• UEFI/GPT Win 7 Load Failure in Dual Boot and no GRUB2 [Ubuntu 12.04]

  - by cristian_jordache

  Configuration: MBB: ASRock X79 Extreme6 Win 7 installed on a INTEL 40GB SSD (GPT partitioned) Ubuntu 14.04 on a CORSAIR 30GB SSD (Ext4 and SWAP) I had Windows 7 installed previously in UEFI mode, using 3 partitions (GPT) and works fine if left alone. In UEFI BIOS settings I can see sometimes a "Windows Boot Manager" and other times (?) a "UEFI Intel" entry for INTEL HDD and Windows will boot properly selecting the one available at that time. I installed Ubuntu 14.04 after Win 7 w/o changing any UEFI BIOS settings and it works fine only if the BIOS is set w/ the Ubuntu partition as the first drive to boot, in AHCI mode. If both SSD drives are connected, the Win7 Intel boot drive can be chosen as first boot device but only as an "AHCI Intel drive" (No "Windows Boot Manager" nor "UEFI Intel device" options available in BIOS Boot menu) and Win7 will not load properly as long as the Ubuntu Crucial SSD is NOT PHYSICALLY DISCONNECTED. Windows will try, start booting for few seconds but will fail replacing Win7 logo and that startup animation with w/ the "old" white progress bar and then and will notify that there is a issue and prompt the user to try to Load Win 7 in Normal Mode again or try a Recovery Mode to fix it. If I let Windows INTEL HDD boot via BIOS/UEFI - Windows Boot manager selection, I may see the purple screen of Grub2 loaded for a while, but there's no selection for Ubuntu or Windows and/or then machine is not booting, showing a black screen and a small command prompt cursor blinking on top. So far the only option I see to have Ubuntu boot side by side w/ Win 7 is to reformat the Win7 SDD and set it boot in legacy BIOS mode with a MBR instead of GPT. Per my understanding this is a quite complex issue to fix (Rod Smith's answer was pretty helpful: UEFI boot on my Asus k52f) but any other suggestions are welcome. I find a bit odd that I can boot properly Windows7 SSD or an Ubuntu DVD using a DVD drive set in UEFI-BIOS in "AHCI mode" and w/ using "UEFI/Windows Boot Manager" booting option but I cannot boot a secondary SSD-HDD w/ Ubuntu having the same BIOS/UEFI Boot configuration. Looks like plugging the second SSD [the Ubuntu partition] is interfering with boot options in UEFI-BIOS.

• How to UEFI install Ubuntu 12.10?

  - by Geezanansa

  Running a newer FM1 motherboard which is using an AMD 3870k APU with a new 1TB HDD. Following the advice in the motherboard manual and https://help.ubuntu.com/community/UEFI have now got to grub option screen for UEFI install. see http://imgur.com/VW5vz The dvd.iso being used is Ubuntu 12.10 desktop amd64 from ubuntu .com. The hdd has had a gpt partition table made for, by using gparted when in a live desktop session when booted in bios mode. (*edit/update: Although the old cd updates on running it is an old kernel and it did make a gpt but that version of gparted uses fdisk whereas gdisk is required to make gpt. Think am going to have to spend more time here http://www.dedoimedo.com/computers/gparted.html lol Using the gparted from 12.10 live session to make partitions; following the guidance regarding this at https://help.ubuntu.com/community/UEFI#Creating_an_EFI_partition, but can only boot to grub option screen http://imgur.com/VW5vz when 12.10 options to "try ubuntu" or "install ubuntu" are selected they give errors as described below*) but after making the gpt decided to leave it unformatted/unallocated space with the intention of using installer to set up partitions. update-originally but gparted now sees hdd as http://imgur.com/hFIvm as described above. *Booting live dvd in EFI mode gives "Secure Boot not installed" just before grub kernel option list with the option to "install ubuntu" but get "can not read cd/0" and "the kernel must be loaded first" errors; when that option is selected. Any pointers on how to get installer going for UEFI install would be good. Thanks in advance. update: Hopefully these screenshots can help better highlight where i am going wrong or if there is something else going on http://imgur.com/g30RB, http://imgur.com/VW5vz, http://imgur.com/31E0q, http://imgur.com/bnuaG, http://imgur.com/y4KGu, http://imgur.com/3u2QE, http://imgur.com/n9lN3, http://imgur.com/FEKvz, http://imgur.com/hFIvm, update: Thank you fernando garcia for pointing me in the right direction to start the process of elimantion. What i have done since asking question is a little home work starting here http://askubuntu.com/faq#bounty and here http://askubuntu.com/questions/how-to-ask. Looking at other similar questions was good fun and found this 12.10 UEFI Secure Boot install the most relative in helping getting ubuntu to uefi install on my system. In response to wolverine's question this article was referred to http://web.dodds.net/~vorlon/wiki/blog/SecureBoot_in_Ubuntu_12.10/ This article in the first sentence gives a link to http://www.ubuntu.com/download which is where i downloaded the 12.10 desktop amd64 .iso(and others) but have been unable to do a efi install of ubuntu on this system and as this is a new system have ended up just going with bios installer running which at least puts my mind at ease that i have not bricked my new mobo.(had to do a clrcmos and flash to latest bios version) So it possibly could be the bios settings or the bios version being used that is problem. To try and eliminate bios version i can not get to post screen in order to id bios version being used. Pressing tab to show post instead of logo and trying to pausebreak to catch post is proving difficult. If logo screen in bios is disabled just get black screen no post shown and pressing tab does not show post. Appreciate using appropriate bios settings and latest 12.10 release should simply get uefi installer running when selected from the grub list (nice graphic details in Identifying if computer boots the cd in efi mode section at https://help.ubuntu.com/community/UEFI#Identifying_if_the_computer_boots_the_CD_in_EFI_mode) And to confirm the hdd is booting in efi mode https://help.ubuntu.com/community/UEFI#Identifying_if_the_computer_boots_the_HDD_in_EFI_mode running the command [ -d /sys/firmware/efi ] && echo "EFI boot on HDD" || echo "Legacy boot on HDD" gave Legacy boot on HDD This is as expected because i allowed the bios installer (which was 12.04 desktop amd64 after trying 12.10 desktop amd64 in efi mode) to run to get a working installation. Which is not what was intended or wished for but wanted to get a working os to bench test new mobo i.e. prove it is working. There are other options as in installing other bootmanagers/loaders but do not wish to do so as shim should get grub2 going that is after secure boot has been signed.(Now got rough idea what should happen just it aint happening. Is it possible ahci drivers are required?) Will post boot info script url of the updated config/setup. The original question asked seems irrelevant to what is being said in this update but as the problem is not resolved will keep on trying efi installing! i.e the problem is same as when question asked just trying to update. Have tried to edit and update the best i can!

• Ubuntu 12.04-2 does not install with UEFI

  - by Rodrigo

  I'm in trouble to instal Ubuntu in Insipiron 14z. I've already created this question (that was wrongly marked as duplicated): First question But, the error seems to be with UEFI. If I disable UEFI on BIOS Setup, I can get into installation process of Ubuntu normally. But, I didn't finish the installation process because I think that will screw Windows 8 installation. So my questions is: Ubuntu installation should work with UEFI. So, why it didn't? Knowing that the error is with UEFI. I can forget the errors listed here?

• Dual booting Ubuntu 12.04: UEFI and Legacy

  - by cmhughes

  I'm trying to dual boot Ubuntu 12.04 (or 12.10) with Windows 8 on a new Sony Vaio, but have run into some problems :) Specifically, my problems seem to come from choosing UEFI or Legacy as the Bootmode in the BIOS. Here is what I have found so far: Windows 8 needs to boot using UEFI, and doesn't work in Legacy mode Ubuntu (both 12.04 and 12.10) needs to boot using Legacy, and won't boot (at least from the live disk) in UEFI mode I have been able to boot Ubuntu using a live USB disc, provided that I change the Bootmode to Legacy. I haven't committed to installing it yet, because I don't really understand the consequences. My main concerns are that instead of simply selecting Windows or Ubuntu in Grub, I would also have to change my Bootmode every single time, which seems like a lot more trouble than it should be. So, the question: how can I install Ubuntu 12.04 or 12.10 in UEFI boot mode?

• Installing Xubuntu alongside with UEFI

  - by Geo

  For the past week and a half I have been trying to figure out how to install Xubuntu 13.10 alongside the Windows 7 install I have on my laptop (ASUS X501A with UEFI) and I'm pretty much at my wit's end. Could someone point me to set of thorough instructions on installing Xubuntu (or any of the Ubuntu derivatives) on a HDD under UEFI alongside Windows 7 64-bit Home Premium? Preferably one that also covers GRUB/bootloader problems that come afterwards. A few additional details: Motherboard does have UEFI. I've disabled Secure Boot and Fast Boot. Launch CSM is enabled and the platform keys are not installed (these settings allow me to at least boot Windows 7). I set the HDD's partition table to GPT through GParted before I installed Windows. I'm installing from a bootable USB that has been created through a tool called Rufus with the GPT partition scheme for UEFI computers option, otherwise I've left it at default. I am able to boot into Xubuntu in UEFI mode, but I'd much rather be able to see the option: Install Xubuntu Alongside Windows 7 (or however it's phrased), Xubuntu seems to be unable to recognize that Windows 7 is installed. I do have access to a bootable USB stick containing GParted though Xubuntu seems to come preinstalled with it. If there's anything else that might be of help, please let me know.

• Cannot boot from K/Ubuntu install disk on my UEFI system

  - by user93241

  I just got a new system and have been trying to get it set up w/ Win7 & Kubuntu dual-boot, but I've got a major problem. The BIOS of my motherboard (an Asus Crosshair 990FX) is strictly UEFI -- there is no legacy support mode available. I've been reading up on how to get Kubuntu installed in UEFI mode but no matter what I try I cannot seem to even boot into my install CD/USB key properly. I can get as far as the selection screen ("Try Kubuntu", "Install Kubuntu"...) but this screen starts off not appearing correctly. If I try moving the cursor around it sometimes seems to correct itself and show me my choices. But once I select "Try Kubuntu" it starts loading, the screen goes black and then proceeds to flicker -- about once every 5-10 seconds or so. This continues indefinitely. I've tried this with both Kubuntu & Ubuntu installation media, even the AMD64+Mac Ubuntu variety that is supposed to be a lot more flexible w.r.t. UEFI. The only hint I've had that the system might have booted correctly is a little drum sound that plays when booting from the Ubuntu install disk. Well, that and the fact that when I hit my system's power button it seems to shut down correctly, even ejecting the CD at the end. This might be a video driver issue; my system has two nVidia 550's, one of which is attached to my primary monitor. (The secondary isn't hooked up yet.) I'll keep looking over similar questions but any advice would be greatly appreciated. UPDATE: I've tried booting into my 12.04 install CD twice now, each time using two different options supplied by my BIOS. One seemed to offer the ability to boot into my CD under UEFI mode -- this didn't even produce the initial boot menu. The other method offers the ability to boot into my CD NOT under UEFI mode. This DOES produce the boot menu, but after this point it seems I still cannot get to a proper video mode to see what's going on.

• HP ProBook 4720s UEFI boot only manually into 12.04

  - by HainjeDAF

  I'm trying to get UEFI boot on my ProBook 4720s. Because I swapped the HDD for a SSD I had a blank canvas to start. The 12.04 Live DVD refuses to boot into UEFI, as do Alternate and desktop CD's. However, when I make a 16Gb flashdrive into a live FS using the bootdisk tool in ubuntu, I can boot from USB, manually into UEFI mode. It even sidesteps to DVD as medium when I boot from USB with 12.04 Live DVD present. I installed a GPT partitiontable with part 1, label EFI, fs FAT32, flag BOOT, mounts at /boot/efi part 2, label Linux-ROOT, fs ext4, no flags, mounts at / part 3, label Linux-SWAP, fs swap, no flags, mounts as swap So far, My system refuses to boot from harddrive by itself. I have to select "Boot from EFI file" and manually browse to (HD0,GPT1)\EFI\ubuntu\grubx64.efi any other option ends in "no system disk, please insert boot disk" I tried installing BURG, but that merely enforces non-efi boot. I tried most of the solutions I could find, but one says \EFI\grub\grub.cfg next says \EFI\ubuntu\ubuntu,cfg I'm confused and getting frustrated. How do I correctly install Ubuntu 12.04 in UEFI mode on this machine???

• Dual Boot Installing Ubuntu 12.04 with Windows 7 (64) on a non UEFI system

  - by Randnum

  I cannot seem to install the correct boot loader for a non-UEFI firmware system. I'm trying to install Ubuntu 12.04 and Windows 7 (64) which are technically compatible with GPT but for windows only if the firmware is UEFI enabled. My system uses the old BIOS system and does not support UEFI. Therefore, whenever I finish my Ubuntu install and try to install Windows I get a "cannot install to GPT partition type" error. Even if I use Gparted to format a special NTFS file format for windows it can't handle the GPT partition style because it doesn't have UEFI. But my ubuntu install always forces GPT during installation and never asks if I want to install the old BIOS style MBR instead. How do I resolve this? Both OS's will install fine on their own the problem is when I try to install the second OS it doesn't recognize any of the other's partitions and tries to rewrite it's own on top of the other. I've tried both OS's first and always run into the same problem. Since there is no way to make Windows recognize GPT without upgrading my Motherboard how do I tell Ubuntu to use the old BIOS MBR on install? Do I have to download a special Ubuntu with a specific grub version? or should I manaually configure my partition somehow to force it not to use GPT? Thank you,

• Install Ubuntu in UEFI mode (unable to boot from USB)

  - by Adele

  I recently bought a Dell Inspiron 15R SE with Windows 8 (64 bit) pre-installed (UEFI supported). I want to install Ubuntu in dual boot with Windows 8. I tried to follow all instruction here : https://help.ubuntu.com/community/UEFI And here : Installing Ubuntu on a Pre-Installed Windows 8 (64-bit) System (UEFI Supported) So, I set Secure Boot to "off" into BIOS and I disable Fast Startup as described here : http://www.eightforums.com/tutorials/6320-fast-startup-turn-off-windows-8-a.html I created a bootable USB key for Ubuntu (Ubuntu 13.10 64bits international Edition) with Unetbootin. The problem is I am unable to boot from the USB key. The computer tries to boot into infinite loop. I also tried to boot from USB with "Legacy Boot" option instead of UEFI. In this case, the computer says there are no bootable devices. Of course, I tried to boot from my USB key on an other computer having normal BIOS and it works perfectly. Have you ideas about what I need to do to be able to boot from USB ? Thanks in advance for your help, Adele

• Ubuntu 13.04 on UEFI system with Windows Boot Manager as the main loader

  - by Mehrdad

  On my old laptop (legacy BIOS, MBR disk), this was perfectly possible to get working: I turn on the computer and see the Windows Boot Manager I use EasyBCD (or BootPart, or something else) to add an option to the BCD menu which allows me to boot into GRUB, and then into Ubuntu I can't figure how to do this on my new laptop (UEFI, GPT disk), whether in UEFI or legacy mode. Currently I've installed (and even booted!) Ubuntu on my laptop, but only with the help of an external GRUB (on a USB flash drive). How can I add GRUB as an option in the Windows Boot Manager on a UEFI laptop? (No, I don't want to change my primary boot loader. So no, I don't want to overwrite the Windows boot loader with GRUB.)

• Live CD won't start with UEFI

  - by skytreader

  I'm trying to dual boot my Windows 8 machine with Ubuntu 12.04 but I cannot even get to the Live CD under UEFI. I've already set my UEFI boot loader to load from the DVD drive before anything else but it keeps on loading Windows 8 first thing. I've checked that the Ubuntu installer I am using is working by setting the BIOS to legacy boot; under this setting, I can get to the Live CD but it cannot detect Windows 8---something I do not want to happen. Just for the record, my boot order is as follows: ATAPI CDROM: HL-DL-ST DVDRAM GT51N USB CDROM: USB FDD USB HDD HDD: TOSHIBA [SERIAL NUMBER] Network Boot-IPV4: Network Boot-IPV6 Windows Boot Manager Has anyone ran into the same problems as me for UEFI? What am I missing here?

• Installing Ubuntu on Asus G75VW (UEFI)

  - by user101653

  You all are my last hope... help! I bought an Asus G75VW from Best Buy. It has the new UEFI BIOS instead of the old style BIOS (1980's) and has Windows 8 preinstalled. I cannot get the G75VW to install Ubuntu 12.10 in EFI mode. I did get Ubuntu to load if I changed the BIOS to CSM and the computer sees and installs Ubuntu in "legacy mode". I attempted boot repair, and Ubuntu will load after 1 minute but as legacy BIOS only. If I changed the BIOS to UEFI "Binary is whitelisted" is displayed and I get a purple screen. My goal... keep my preinstalled Windows 8 on internal drive bay 1 and install Ubuntu 12.10 on internal drive bay 2... and somehow make a choice on which to choose. I am at a loss. I am a software programmer, but I am very bad at understanding BIOS and partitioning. Any ideas? Has anyone done what I want to do. This is a full second day on my "issue"! If I cannot get Ubuntu installed, I'm returning the laptop. And "wait" until these obstacles of UEFI/EFI and properly handled to allow people to load EFI based Ubuntu without a hitch. Thanks, Dave

• Problems dualbooting Ubuntu because of UEFI

  - by Koffeehaus

  I have an X-series Asus laptop which I just bough about a month ago. I want to dualboot Ubuntu - Windows. I can easily access LiveUSB with both UEFI enabled and disabled. I heard that there were problems with UEFI, so I disabled it. After I've installed the system I couldn't access it. It just boots to Windows straight. Another unusual thing, that never happened to me before was that the partition editor wanted me to create a BIOS reserved area, which I did, but not at the beginning of the table. Any ideas how to access the Ubuntu partition? As far as I can guess both Windows and Ubuntu have to be both of the same type of boot, either Legacy or EFI. This is not the case of what I have now. So, if I reinstall Ubuntu in UEFI mode that correlates with my Windows type, will I then be able to boot into it? I have a constraint, my laptop doesn't have a CD ROM, so I cannot reinstall WIndows, nor can I move around the Windows recovery partition. This is the boot-repair report : http://paste.ubuntu.com/1354254/

• Making an Ubuntu installation disc UEFI bootable

  - by skytreader

  I'm trying to install Ubuntu 12.04 on a machine with UEFI (Windows 8). Following Rod Books, I managed to get my system to boot using rEFInd. However rEFInd does not offer me any options to boot from my Ubuntu installer disc. Another thing...after following Rod Books' instructions, my machine greeted me with something along the lines of "The bootloader is not trusted" (my usage of the term "bootloader" is possibly wrong; I'm not well-acquainted with these terms) I got to work around this by setting up some passwords in the BIOS and putting the renamed .efi of rEFInd to the trusted list. While in this screen, it showed me the drives with a possible .efi (among them, the drive S in Rod Books' guide) and one of the drives it showed was my optical drive with an Ubuntu installer. I tried browsing for an .efi in the Ubuntu installer but found none. True enough, at Windows, I searched the drive for an .efi but found none. So how do I make my Ubuntu installer UEFI bootable?

• Installed UBUNTU12.04 in Legacy, when changed to UEFI just runs the Terminal, not GUI

  - by jraulvc

  Well, I installed Ubuntu 12.04 in a Gateway NE 522 with Windows 8. First, I had to install it in Legacy mode, because in UEFI it would not run the bootable USB. In the Legacy mode it runs perfect. Once done that with help of the "Boot-Repair" I changed it to the UEFI and disabled the secure boot mode. GRUB runs fine but when I run ubuntu I get the following message: microcode: failed to load file amd-ucode/microcode_amd_fam16h.bin kvm: disabled by bios kvm: disabled by bios kvm: disabled by bios and then I just get access to the terminal. From there, I have already tried with reinstalling unity and gmd. When I try to install amd64-microcode the same error ocurrs ( microcode: failed to load file amd-ucode/microcode_amd_fam16h.bin ) by the "updating the microcode on all online processors..." phase of the installation. Can somebody tell me how can I recover the graphical interphase of ubuntu from the terminal? Thanks a lot

• Dual Boot Windows 8 UEFI and Ubuntu 12.10

  - by 0x4a6f4672

  I have got a new Samsung Series 7 laptop with Windows 8 where I tried to install Ubuntu. It is a 64-Bit system which uses UEFI and has "Secure Boot" switched on in the BIOS by default. After I switched if off (and set it to "UEFI and CSM OS") I was able to install Ubuntu (Ubuntu 11.10, which recognized Windows as Windows Vista, although it is Windows 8), by booting from CD with Settings/Change PC Settings/General/Advanced Startup in Windows 8. But after the installation and the restart of the machine somehow ignored Ubuntu and booted only Windows 8. Then I tried to reinstall Ubuntu 12.10. It still only boots Windows 8. Then I tried Boot Repair, which was not really helpful. Any ideas how I can create a dual boot system with Windows 8 and Ubuntu 12.10 ? Here is the link that Boot Repair generated: http://paste.ubuntu.com/1368624/ Is it necessary to create an extra EFI partition with GParted?

  I want to upgrade my machine with a new Motherboard, RAM and Processor. I am planning on doing a clean install of Ubuntu 12.04. The Motherboard I want to use is an Asrock 970 Extreme4 which uses an AMI 32 MBit UEFI BIOS. My Question is, is there anything I have to watch out for during the installation process? Cause I have read that some people have trouble booting into ubuntu using a UEFI BIOS. Any advice? I don't want to spend all that money for the different parts only to find out that I can only use windows properly. Thanks in advance

• Install problem on UEFI, Windows 8 new desktop

  - by albuquerque mat

  I just bought an HP desktop, p6-2326s, which has windows 8 installed. I have tried booting a Ubuntu live disc but the machine won't boot it. When I bring up the UEFI boot menu it offers a selection of UEFI BOOT SOURCES, windows boot manager, dvd drive, IP4 Ethernet controller, or IP6 Ethernet controller. If I select the dvd drive with the CD in it I get the message "Secure boot violation, Invalid structure detected. Check secure boot policy in setup." With all other selections it just boots into windows. So where do I go from here?

• UEFI Dual-Boot - Ubuntu 12.04.3 + Windows 8.1 (One GPT HDD)

  - by swafbrother

  UEFI Dual-Boot - Ubuntu 12.04.3 + Windows 8.1 (One GPT HDD) Hello, I'm having trouble setting up a dual-boot (Ubuntu 12.04 LTS and Windows 8.1) in my ASUS K55VM laptop's hard drive disk (500 GB). I was mostly following tutorials for doing this, but at some point something has gone wrong. Up to now, I have followed these steps: I formatted my HDD into GPT. I clean-installed Windows 8.1. I didn't prevent Windows from choosing the partitions to use and it created these partitions: A Recovery partition (sda1). An EFI System Partition (sda2). A Microsoft Reserved Partition (sda3). A Windows Data Partition or C drive (sda4). I reduced the Windows Data Partition via Windows' Disk Management. I made a bootable USB Stick with Ubuntu 12.04 LTS from ISO, using Universal USB Installer. I created these partitions for Ubuntu: A Boot partition, mounted at /boot (sda5). A Root partition, mounted at / (sda6). A Swap partition (sda7). In Device for boot loader installation I chose: /dev/sda. Then, when I rebooted, it went straight into Ubuntu. So I installed Boot-Repair, and clicked on Recommended Repair. It automatically did its job without asking for anything. I rebooted and Grub showed up, with a lot of options. At this point I had a decent dual-boot setup; Ubuntu and both Windows entries worked fine: Ubuntu. Windows Boot UEFI Loader. Windows UEFI bkpbootmgfw.efi. I executed this command: sudo grub-install --force /dev/sda5. Then I tried to make Windows 8.1's Boot Manager the main boot manager, so that I could choose which OS to boot into from a menu. I downloaded EasyBCD on Windows. It showed 2 Ubuntu entries and 1 Windows entry. I went into BCD Deployment tab and clicked on Write MBR. At this point, I went into BIOS and made Windows Boot Manager the first boot option. When I rebooted, I got a black screen with the message efidisk read error, and then (I guess) it switched to the next boot option, which is Ubuntu, resulting in Grub showing up. From Grub, Ubuntu entry is working and so are both Windows entries. If I choose Ubuntu, it normally boots into Ubuntu. But if I choose Windows, it goes into Windows' boot manager. In Windows' boot manager, a menu shows up: Ubuntu. Ubuntu. Windows 8.1. If I choose Windows, it boots into Windows without any problem. If I choose Ubuntu, it boots into Grub (back to step 14). Here's my BootInfo Summary: http://paste.ubuntu.com/6698171/ Windows Boot Manager is clearly not working as expected; I can't directly boot into it and I can't boot into it from BIOS either (efidisk read error again). If I want to boot into Windows I need to boot into Grub first, which is the opposite of what I wanted. I need help at this point. What is the best thing I can do? Is there a more reliable and/or simpler way of acomplishing a satisfying dual-boot for this situation? Can someone provide a way for going back to step 8, where I had a more efficient dual-boot setup? If only I could undo what I did with Easy BCD and skip Windows' Boot Menu... Can someone provide a way to fix this mess? Thanks in advance and sorry for the length of this, I wanted to be exhaustive.

• Boot existing ubuntu installation on uefi, GPT BTRFS

  - by user204720

  I have looked through many of the questions, and haven't found anything that quite satisfies this problem. I have an ssd hard drive that is bootable from my old computer. It is a standard BIOS, however, I built a new computer with Z87 motherboard that is a UEFI. What I'd like to do is boot from this hard drive without wiping out the hard drive. I've tried booting from legacy mode, doesn't seem to work. Part of the multitude of problems is my partitioning scheme, which is GPT. sdx1 is the btrfs system, sdx2 swap, sdx3 is bios_grub. I've tried setting the UEFI/BIOS to boot in legacy mode, I've tried turning my swap partition into a Grub EFI boot, I've tried copying the file system onto a new drive installed on the new system. However, copying the information doesn't keep the filesystem or subvolumes intact. I've also tried boot-repair which is when I overwrote the swap space. I'd really rather not start over on a new install, so any other suggested trees to bark up would be appreciated. For the record, I hate you Microsoft, and ASUS I understand complying with microsoft, but make it optional... I'm really disappointed in that I have to deal with Windows 8 when I have nothing to do with it. Something I think I could try, but would like to hear from more experienced users. Moving the sdx1 (btrfs /@/@home) partion and opening up a 100 MB partition on the beginning sectors and install efi compatible Grub2 installation. Would it work? How to move a partition?

  When trying to start Ubuntu from my USB key in UEFI mode (it works in Legacy mode, but I have to keep Windows) on a Dell Inspiron 15z , Grub starts, but when I choose any option, I get a black screen and my USB key stop teling me it is being read. EDIT: when using the legacy mode and trying to install Ubuntu, I get a blank partition table with Ubiquity… … and a very strange partition table from GParted (I have a hybrid 32Go SSD + 500Go HDD disk) :
