• Ubuntu 12.04 on Lenovo ThinkPad with UEFI

  - by Oleksandr

  I have installed Ubuntu 12.04 Desktop amd64 on my Lenovo ThinkPad E330. There were no problem during installation. Now I can boot to Ubuntu and use it. BUT: now there is only one option in Boot Devices in my ThinkPad's BIOS: ubuntu I can boot ThinkPad to Ubuntu on HDD ONLY - no other options. I switched BIOS to "Legacy devices only" - this did not help :( Could you, please, help me and explain how to boot my ThinkPad from USB drive? How can I switch back to Legacy devices and use MBR, not UEFI? Thank you!

• Problem with Ubuntu and UEFI (Problem with any linux OS)

  - by K.T.Sumant

  I have purchased a new Sony Vaio laptop and it is said that the Windows in the recent laptops is installed in the UEFI mode. But all the Linux OS are installed in default in Legacy mode. When I reboot my laptop, Ubuntu is not being detected on boot. Only Windows is detected. To access Ubuntu, whenever I boot the system, I need to: (1) enter the boot menu, (2) change the mode to legacy, and (3) type a bit of scary commands in grub then Ubuntu successfully opens. This is a bit of problem for me. So I wanted to know the solution for this problem. So please kindly look over my problem as soon as possible.

• Windows 7 doesnt boot after installing Ubuntu 12.10 (Asus Zenbook Prime / UEFI problem)

  - by jpdus

  Today I installed Ubuntu and since then i cannot boot into Windows anymore. I used the "standard" option (didnt change any partitions manually, just entered the size) but used the UEFI-mode. At first the GRUB entries for Windows did not work at all, after reading this thead i was able to add a new Grub entry - now i can get into the "windows-loading" screen for a few seconds but then i always see some kind of bluescreen for a fraction of a second and the laptop reboots. I can get into the windows recovery partition but the only option there is to reset everything to factory settings (+erase all data). I have no idea how to get into the Windows 7 repair mode which was mentioned here (tried everything else in this thread too - no success). My boot info can be found here: http://paste.ubuntu.com/1411573/ I have no idea what went wrong (there is even an extra page for the Zenbook Prime where no installation problems are mentioned). I would appreciate any help/ideas, many thanks!

  I've built a new system, and I want to take full advantage of UEFI and Ubuntu. So I install Ubuntu, and try to boot from it, and my BIOS (Asus EZ Mode / Advanced Mode) simply says "No bootable medium found. Insert Bootable Medium and press any key to try again." So I've reinstalled several times, without any failures, Ubuntu IS installed, and I've tried Ubuntu Boot Repair (link below) and nothing I do seems to work.

• Impossible installing Ubuntu 13.04 in UEFI mode with Windows 8 preinstalled

  - by Lautaro Vergara

  I know this is a dejavu but let me please explain my problem. When booting 13.04 installation media EFI mode get to a black screen with Grub version 2.00-l3ubuntu3 version appears after selecting "install" or "try Ubuntu", there appear error messages: - failure reading sector ... from 'cd0' - you need to load the kernel first I have a Dell Vostro 3560 with Windows 8. I have downloaded and burned ubuntu-13.04-desktop-amd64.iso. Hashes checked. I've booted from the dvd with Secure Boot enabled. The same happens when Secure Boot is disable. When booting with Legacy BIOS, installation starts. I tried Ubuntu without installing and looks OK. BUT, I did not follow the installation because in https://help.ubuntu.com/community/UEFI#Converting_Ubuntu_into_EFI_mode there appears "if the other systems (Windows Vista/7/8, GNU/Linux...) of your computer are installed in EFI mode, then you must install Ubuntu in EFI mode too.", which is the case in my computer. I have read many similar questions and the corresponding answers from people in this forum, but till now I haven't found a solution. Could someone help me on this subject? Thanks in advance!

• Install Ubuntu 12.04 in UEFI mode on a HP Pavilion dv6-6c40ca

  - by Marlen T. B.

  I have recently (as of July 2012) bought a HP Pavilion dv6-6c40ca laptop. It came pre-installed with Windows 7 on an MBR. I installed Ubuntu 12.04 on it on a GPT partition in what I think is BIOS emulation mode. I made a BIOS-Grub partition so the install didn't fail. That is what it is for .. right? Now I want to upgrade to UEFI mode. How would I Install Ubuntu 12.04 in UEFI mode on a HP Pavilion dv6-6c40ca. Or is it impossible? My laptop, despite its new age may not be UEFI 2.0+ capable. If it isn't how can I install a software UEFI (i.e. a DUET such as the one by tianocore). Or is this too impossible? A link to my laptop's specs is: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03137924&tmp_task=prodinfoCategory&cc=ca&dlc=en&lang=en&lc=en&product=5218530 My laptop should have a UEFI given this link from HP http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c01442956#N218. And from the link I draw a quote: That means most notebooks distributed with Windows Vista, and all notebooks distributed with Windows 7, have the UEFI environment. My laptop had Windows 7 Home Premium pre-installed. OK. Following the comments so far -- NOTE: I am trying to do this on an external drive so I can see if it works. I have partitioned the drive using GParted as a GPT drive. Created a 200MB partition at the beginning of the drive with a FAT32 file system. Given the 200MB partition a label of "EFI". Set the boot flag on the 200MB partition. What should a do next to install Ubuntu 12.04? Given the link: https://help.ubuntu.com/community/UEFIBooting#Selecting_the_.28U.29EFI_Graphic_Protocol In my first read through (just to see if I will understand everything before I start) I get to step 2.3 Install GRUB2 in (U)EFI systems The first line is Boot into Linux (any live ISO) preferably in UEFI mode. Um .. how do you tell what mode your live CD is in?! And how do you change it if the mode is wrong?

• UEFI Boot Failure - Hang after Printing USB Information

  - by James

  I'm experiencing a really weird boot problem. With both 12.10 and 12.04LTS, the vast majority of kernels (and initrds) that I've tried boot, but hang immediately after printing out information about USB devices. This isn't exactly a full "hang" so to speak, as if I plug in a flash drive, I see information and a /dev/sd* entry printed to the screen. Post/pre-init scripts are not run, there is no handoff, nor busybox or VT prompt. Virtual terminals can't be changed (with Ctrl-Alt-Fx). For what I can see, init may have not been executed yet. With certain kernel and OS combinations however, (specifically 3.2.0-29), I get a full boot and am able to use the OS as if there is no problem. After 3.2.0-29, I've been hard pressed to find a kernel that works. Any idea what's happening or how to fix this? Or even a road to take? I've exhausted the first five pages of Google for every search term I can think of. This is a Lenovo Z580 (i5-3210M) with Phoenix SecureCore Tiano firmware, if that helps any.

• Grub errors during UEFI dual boot for Windows 8 (can't find command 'drivemap')

  - by luca-mastro

  I have got a newly bought ASUS N56V with Windows 8 preinstalled. I needed to install Ubuntu so i partitioned the disk and after having disabled the Secure Boot option from Windows 8 i successfully installed Ubuntu 12.10 from a Live USB. The problem is that if i try to access both to Windows 8 (loader) and Windows Recovery System (loader) from the GRUB menu, these two errors show: can't find command 'drivemap' and invalid EFI file path and it goes back to the grub menu. In conclusion I do not have access to my Windows 8 partition but can only use Ubuntu. How can I solve the problem? I am pretty new to the matter. Thank you!

• UEFI hardware and dual booting with windows

  - by user39803

  I've been struggling for 3 days trying to dual boot Ubuntu 11.10 and Windows 7. I want to use an SSD for my Ubuntu installation and an hdd for Windows. I realized that I have to install windows first and then ubuntu, and so I did that. When I first install windows it boots fine from my hdd, but when I add ubuntu on my ssd and restart, I get a black screen with a blinking cursor. I've read many forums where this is asked but haven't found a single solution that works. I've tried boot repair. It told me to make a fat ESP partition and I did that as well but it still doesn't work. I'm a noob and any suggestions would be really appreciated.

• Dual booting Windows 7 and Ubuntu 12.10 on UEFI laptop

  - by fccoelho

  I have a notebook pre-installed with Windows7 and I installed Ubuntu 12.10 on it following the standard installation steps in the installation image. The only problem is that on reboot the machine continues to boot Windows ignoring the presence of Ubuntu (Grub never comes up). My partition scheme is this sda1: NTFS 612MB sda2: NTFS 50GB (after resizing during Ubuntu installation. This is the main windows partition) sda4: extended sda5: ext4 /boot sda6: btrfs / I have tried Boot-repair and it didn't help. Tried rEFInd boot manager but it doesn't support NTFS partitions. I don't know what else to try. My next attempt is to try to install GRUB by hand to the MBR. Any other Ideas?

• How to create an UEFI bootable USB stick from an ISO

  - by shiin

  I have an ISO image of my backup solution's recovery cd. When I burn the image to a CD-ROM, I can boot from it in UEFI or normal mode without problems. Unfortunately, this is no solution for my laptop, as it does not have an optical drive. Thus, I tried to create a bootable USB stick that can also boot in UEFI mode, but so far I have not been successful (note that the laptop has UEFI and boots Windows 7 in UEFI mode). So my question is, if anyone knows how I can get said ISO on my USB stick so that it boots as if I would use a CD-ROM?

• How to install Ubuntu Server 12.04 in a Virtualbox VM with UEFI boot enabled

  - by Deleted

  I have a server which I'd like to install Ubuntu 12.04 on, but I've had some problems and thought it would be nice to get things working in a Virtualbox VM with the same features as the server. I want to enable UEFI-boot in the VM. I "Enable EFI" in the System / Motherboard settings for the VM. I make sure the Ubuntu Server 12.04 ISO is inserted when I boot. And yet I get stuck in the UEFI boot console when I start the VM. How do I install Ubuntu Server 12.04 in a UEFI boot-enabled Virtualbox machine?

• Dual boot UEFI Windows 7 and Ubuntu 12.04 (both 64 bits). W7 entry doesn't appear in GRUB

  - by Joe

  After trying to install both OS during 2 days, I'm confused and getting mad... I have SSD 128 GB and HDD 500 GB both empty. My laptop is Asus K55VM. BIOS support UEFI. What I have done: Install new SSD (Samsung 830 128GB) Use GParted on liveCD to create new table of partitions (GPT) and create 3 partitions (in the SSD) for different purposes: Partition 1: 80 GB (w7); Partition 2: 30 GB (Ubuntu 12.04 -Just / -); Partition 3: 10 GB unused (for future extesion of the other partitions) Install Windows 7 (with UEFI) in Partition 1. This create: /dev/sda1 - 100 MB for System (UEFI boot I guess) - FAT32 /dev/sda2 - 100 MB aprox. for MSR /dev/sda3 - 79.800 MB aprox. for Windows7 data In this point everything works fine. I have W7. Now I install Ubuntu 12.04 amd64 (with UEFI) as follows: Install / in Partition 2 - /dev/sda4 30 GB ext4, and in the hdd I install /home and swap. I select bootloader in /dev/sda1 (where it's supposed to be the UEFI boot). I install updates and reboot. Problem: Now just appears grub menu with Ubuntu entries and not Windows 7. Alternative solution found: When I turn on laptop, before loading GRUB I press ESC key and appear BIOS boot, so I can select to boot the Windows partition, Ubuntu partition, DVD, USB, etc... but I think is not the best way to boot different OS. I've tried: sudo update-grub2 with no success. What can I do??

• Make UEFI, GPT, Bootloader, SSD, USB, Linux and Windows work together

  - by user129552

  I like to use the latest hardware and the latest software; thus I have a Laptop (Lenovo X220) with UEFI instead of BIOS an SSD instead of an HDD GPT partitioning scheme instead of MBR USB to boot from instead of optical disks. I need to use both Windows and Linux. I tried to make them work alongside, but I didn't succeed. Most Linux distribution isos don't even really work on UEFI systems booted from USB. (Not even the self-claimed cutting-edge Fedora. I also tried Linux Mint Debian Edition and Sabayon Linux (according to this guide) which did not work. Only Ubuntu worked for me. I first installed Windows 8 which created sda1: Recovery, sda2: EFI system, sda3: msftres, sda4: NTFS Windows. Windows worked without a problem. I then created sda5: linux-swap and installed Ubuntu into sda6: btrfs. After rebooting, I was not presented GRUB2 as expected, but instead my system just booted into Ubuntu. I could no longer access Windows. After fixing dpkg in btrfs Ubuntu, I followed the Ubuntu documentation on UEFI booting. The result left me with a broken GRUB2, but interestingly, when I wanted to select the device to boot from, I was not only presented the internal SSD, an attached USB device, or LAN, but also Grub2 (broken), Ubuntu and Windows. The result is not very satisfying to me. What would I have to do to fix everything? Or differently asked, what operating system should I install at what point given my possibilities and requirements, so that I have a working bootloader in my UEFI GPT system which presents me a working Linux and Windows.

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

  - 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,

• No discs found when trying to install Windows 8 with UEFI

  - by Sahas Katta

  I have a Vizio Notebook (CN15-A5). It came pre-installed with Windows 8 x64 and is taking advantage of UEFI out of the box. The BIOS (APTOS AMI) is in Secure Boot mode with the OS selected as "Windows 8". I removed the stock HDD that came with the machine and put my own SSD into it. I created a Windows 8 Pro x64 installation disc on a 4GB USB flash drive formated as FAT32 since its apparently required for UEFI. When I boot from the USB Win8 installation disc, I get suck when I reach the "Custom: Install Windows only" section. Normally you would see a list of available discs and their partitions, however my entire list is blank. If I head back to the BIOS and disable Secure Boot and set the OS to "Other OS" and attempt again, I am able to see the list of available discs in the system and can install a copy of Windows 8. Unfortunately, doing it in this method results in an installation with a traditional 350 MB partition + OS partition instead of 4 partitions which is normal for a UEFI setup. Has anyone run into this problem? I've tried loading defaults in the BIOS and attempting to install via every combination with no luck. Any help would be appreciated.

• Cannot install CentOS 6.5 using UEFI usb boot

  - by Vaindil

  I am trying to dual-boot CentOS 6.5 on my desktop that is currently running Windows 8.1. I have two storage devices: an SSD that has my Windows installation, and an HDD that has all of my data. Both are formatted using GPT, and Windows boots using UEFI. I used the CentOS 6.5 live DVD (CentOS-6.5-x86_64-LiveDVD.iso) to create an EFI-bootable flash drive (it does boot properly in EFI mode). I receive an error, however, when CentOS is booting (error is below). I have a 6.4 boot DVD which boots as expected, but it does not boot in UEFI mode and therefore doesn't play nicely with my Windows installation (I have no way to access it, even using rEFInd or any other similar tools). What do I need to do to get the device to boot properly in UEFI mode? Kernel panic - not syncing: Attempted to kill init! Pid: 1, comm: init Not tainted 2.6.32-431.el6.x86_64 #1 Call Trace: [<ffffffff815271fa>] ? panic+0xa7/0x16f [<ffffffff81077622>] ? do_exit+0x862/0x870 [<ffffffff8118a865>] ? fput+0x25/0x30 [<ffffffff81077688>] ? do_group_exit+0x58/0xd0 [<ffffffff81077717>] ? sys_exit_group+0x17/0x20 [<ffffffff8100b072>] ? system_call_fastpath+0x16/0x1b drm_kms_helper: panic occurred, switching back to text console

• Windows 8 preinstall downgrade to Win 7: UEFI problems :/

  - by Tim Flemming

  I have a friend who has a Hp Laptop with UEFI booting. He locked himself out of windows 8 (forgot his password)... so he called me. Well after trying to use the latest version of chntpw in UBCD5.2.6, i came to the conclusion i needed to wipe the drive and install windows 7. A little googling suggested using certain versions of chntpw, but i decided to not waste the time burning endless CDs. Anyway, He agreed to installing Win7 "I hate the big tile thingys". So i attacked with Gparted. Wiped the whole drive. Set flags to boot. Set part table as MBR. However upon trying to install win7, it still claimed i had a GPT style disk. unable to install. the only thing i can think of I'm doing wrong is not changing the bios/UEFI to legacy... My question is, If I enable legacy, somehow get the drive to actually be MBR, and use my X86 DVD, should I be good? Is there some common glitches ppl miss when dealing with GPT/EFI/UEFI? I need answers cuz he now has a blank laptop which I am responsible for. Another question. windows 8 came installed on a GPT disk. SO WHY WHEN I BOOT THE INSTALL DVD DOES IT SAY IT CANT INSTALL TO A GPT STYLE DISK??? WTF??? talk about the bleeding edge man.

• How to load kernel from live cd on UEFI install of Ubuntu 12.10?

  - by Geezanansa

  Running a GYGABYTE FM1 motherboard which is using a AMD 3870k APU with a new WS Caviar 1TB HDD. Following the advice in the Motherboard manual and https://help.ubuntu.com/community/UEFI have now got to grub screen for UEFI install. The dvd.iso being used is Ubuntu 12.10 desktop amd64. The hdd has had a gpt partition table made for, by using gparted when in a live desktop session(booted in bios mode)but decided to leave it unformatted with the intention of using installer to set up partitions. Booting live dvd gives grub 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.

• Windows 7 won't load unless other harddrives "disconnect"ed in UEFI shell

  - by lmz

  I have three disks, one GPT partitioned containing Windows 7 and Debian, the other MBR partitioned containing CentOS, and the other one MBR partitioned, empty. It used to work (loading Windows boot manager using rEFIt) but now after installing CentOS and OpenIndiana on the second drive, Windows won't boot. The logo is displayed briefly and then a text mode scrollbar "Loading files", then back to the rEFIt menu. The only thing that makes it work is if I drop into the UEFI shell and run disconnect XX where XX is the device handle of the other hard drives (obtained from running devices). This makes me think that the bootloader is getting confused about where the Windows partition is. Is there any information on how the Windows UEFI boot loader finds the Windows partition, or is there any logging I can turn on to help troubleshoot this issue?

• GRUB2 UEFI booting from LVM on RAID (with XEN)

  - by pavian

  I'm experimenting with booting root fs from LVM volume inside the raid (mdraid superblock 1.x) via UEFI with GRUB2. Also I'm using Xen hypervisor. From grub command line I can see my lvm volume (ls command) but I got kernel panic due to "unable to mount root fs". I saw a note in this article telling it's probably impossible to boot root fs from raid via UEFI, but I don't understand the reason why not. Is it possible to boot linux with this configuration without the initramfs (which I don't won't to use)?

• List of recent motherboards with BIOS / without UEFI [on hold]

  I am building a new desktop PC and I want to have full disk encryption on it. TrueCrypt doesn't support UEFI as of now. Are there still recent motherboards out there without UEFI ? I didn't find any list and I am afraid that I will have to study each potential candidate's technical sheet before purchase. I want to buy 2 or 3 of the same model to be future proof. Newegg links will not help, I don't live in the USA ... this means that this post is a legitimate target for PRISM ;-) Thanks for your help.

• What is UEFI and Secure Boot? How do they affect Ubuntu?

  - by Oxwivi

  Discussions and reports about UEFI and Secure Boot has cropped up in many Linux circles, but can anyone summarize it's impacts on Ubuntu and how it affects the general users? I know that UEFI and Secure Boot are separate (not interchangeable), with Secure Boot being a part of the Unified Extensible Firmware Interface BIOS specification. PS I do know how it affects Ubuntu, this question is for the benefit of public knowledge.
