• Bootloader error Ubuntu 12.04, system goes to Grub-rescue instead of booting

  - by user83508

  I am trying to install ubuntu 12.04 on my system but it is constantly giving me bootloader install fail error. I have tried to lot to solve this issue but reading articles over the internet but still no gain. Firstly since the bootloader was not getting installed I tried to install it on all the alternative paths given in the installer, failing with I selected install ubuntu without bootloader. Then I tried to manually install bootloader via terminal at try ubuntu via grub-install, but I was not able to do that. Then I tried using boot-repair and it was also not able to install the bootloader because after it my system shows grub-rescue. I tried to use boot-repair and install bootloader on a seperate partition mounted to /boot and still my system is booting and it still shows grub-rescue. The error which my system shows during boot is: Error : no such device : 04ac0510-bd4f-43b8-b885-b885-11c4dec21db8 I am not dual booting and ubuntu is the only OS I am installing. I am using Raid 0 with two blue western digital hard drive so I am not sure whether it is right or not. The details given by boot-repair are in the below mentioned link; http://paste.ubuntu.com/1147208/ Afterwards, I made one more change I installed ubuntu again and this time I installed the bootloader at a different partition on /boot. After this the bootloader error has gone but I am still not able to boot to ubuntu as I get the same error I was getting before. I have not installed dmraid, I feel it is neccessary for Raid0, but I thought ubuntu already has Raid drivers. Moreover in the dmraid installation instructions for 12.04, I used the one for 10.04 and selected to install bootloader at the partitions from the dropdown. This time the installation finished normally without an error but still I am not able to boot my system as the same error shows during booting this time also. Now I am stucked and I have no clue on how I can boot my system. Please tell me how can I boot my system.

• Where to install Ubuntu bootloader on a Mac?

  - by ylhtravis

  I'm trying to install Ubuntu on a Mac, but I can't get it to boot with default mac bootloader or rEFI. It shows up as "Windows" On the mac bootloader and shows up as "Linux" on rEFI. I'm not sure where should I install the bootloader to during installation. Here's my partition table: sda : Hard drive manufacturer name sda0: Mac partition sda1: ... sda4: SWAP sda5: Ubuntu And I have installed the bootloader on sda5. Should I install it on sda instead? I'm afraid this will replace the default Mac OS X bootloader and I won't be able to go into the Mac side again. Any help will be greatly appreciated. Thank you.

• Ubuntu 12.04 Bootloader failed to install

  - by Chris

  Sorry about the excessively long question, but I figured giving more information would be better. I recently bought a new desktop for myself, running Windows 7. It has two hard drives, and I wanted to install Ubuntu on a small partition on the second hard drive. I created 25GB "free space" in Windows and ran a LiveCD install. I wanted to select the install options myself but accidentally selected "Install alongside Windows 7," but it seemed to pick up the free space and installed itself there as I wanted it to. However, I was told that the bootloader installation had failed. I chose to "Cancel installation," leaving my computer unable to boot. I wiped my computer and reinstalled Windows. After that, I tried installing Ubuntu through Windows using WUBI, once using files from my LiveCD and once downloading everything again. Both times the install succeeded, but both times when I restarted and tried to load Ubuntu, it gave me an error - wubildr.mbr was corrupt or missing. I checked in Windows - it was indeed present on the C:\ drive. I went back to the LiveCD installation, this time going the custom options route. I assigned 16GB to an Ext4 journaling file system and 10GB to a swap file. I got the same bootloader error as before. Being prompted to select a different partition to install the bootloader to, I first tried the partition Ubuntu was installed on. A window came up saying that the install had succeeded, but a second window gave me the same error and choices as before. I went through every single option it gave me, including the Windows partition and the hard drives themselves (dev/sda, dev/sdb). Same result. I then chose to not install a bootloader. Windows still works fine, and I assume Ubuntu has installed but is unbootable. Knowing that my computer could potentially brick itself again - and, this time around, with a lot of data to lose and hassle to go through if I mess it up - I really don't want to do anything without some advice. So I'll ask this: a) Why did the bootloader fail to install? Can I fix the error and install Ubuntu fresh? b) Is there any way to get around the error, install the bootloader, and point it towards an existing installation of Ubuntu? c) Is there a quicker and easier solution I might have missed? EDIT: Thanks for the tip, AthloX. After testing the liveCD in Virtualbox with no installation problems, I looked around for some alternate bootloaders but had no success. I attempted another install, which installed the bootloader and Ubuntu just fine but bricked Windows 7. I wiped both hard disks clean, including some "System Reserved" partitions I hadn't noticed before, before re-installing Windows 7 on one hard drive and immediately afterwards installing Ubuntu on the other. Now the computer boots into Windows, but I can pop into the BIOS at startup to boot into Ubunbtu via it's bootloader, and I'm guessing it'll only take a bit of poking at the BIOS to swap the load order. Many thanks!

• Create Windows Bootloader/Boot into Windows from Ubuntu

  - by Kincaid

  I have computer that dual-boots (or tri-boots) Windows 8 Release Preview, Windows 7, and Ubuntu 12.04. Grub boots between Windows 8 and Ubuntu; for which I use primarily. Recently, I have decided I wanted to remove Ubuntu, as I hardly used it. As a stupid mistake, I deleted the Ubuntu partition before changing the bootloader to replace Grub. Whenever I know boot the machine, it gives me the "grub-rescue" prompt -- I am unable to boot into either Windows (8 nor 7), nor Ubuntu (except via USB, of course). I do not have any Windows 7/8 recovery media, so that isn't an option. Please note that after I deleted the Ubuntu partition, I put the PC into hibernate, and then turned it on. This means the C:\ [Windows 8] drive cannot be mounted. I don't know if that is bad, but it definitely doesn't make things better. I am currently booting Ubuntu via USB, in an effort to restore the Windows bootloader solutions. I have looked into using boot-repair to solve the problem using the instructions here, although after attempting to apply the changes, it gave the error: "Please install the [mbr] packages. Then try again." I don't know why I'm getting this error; is there a way to install the 'mbr packages?' I honestly don't know what exactly they are, nor how to install them. Is there any options I have not yet exhausted to be able to boot back into Windows, in the case that there is a better way? In the end, I want to set the bootloader to boot into Windows 8, but booting into either Windows 7 or 8 is fine -- I can use EasyBCD from there. Is there a simple solution to this? I've checked BIOS, and I haven't been able to find a way to boot into Windows. Any help would be greatly appreciated.

• Reinstall of Windows Bootloader not working

  - by MrBoxy

  It first started when I deleted my partition that had Ubuntu 12.04 on it. Little did I realize at the time that it would destroy all the resources of Grub on it, and subsequently prevent me booting into my hibernated windows. So I made a 12.10 Ubuntu live USB and reinstalled windows bootloader. When I rebooted it gave me a bootloader error saying I that it could not find the resources to boot from. So I went back to my live USB and installed boot-repair and tried to repair the mbr. It didn't work though. Here is the URL the boot-repair gave me if I was in trouble: paste.ubuntu.com/1328309 Thanks in advance :)

• What location to put bootloader, when running multiple drives and partition

  - by Matt G

  I have Win8 on my desktop, where a 120G SSD is used to run windows and some select applications, while I have a 2TB HDD to provide basic file storage and where possible, install applications instead of on the SSD. I want to install Ubuntu on a new partition of the HDD (I allocated 300GB, with 5GB swap file). I've used a USB to install the OS, which seemed to have done the job. However, after prompting for a restart, I can no longer boot to ubuntu. During instillation I was confused about where to install the "boot loader instillation". I ended up selecting "/dev/stb" because I figured I would be able to boot with BIOS by selecting the HDD drive as a priority over the SSD. The bootloader is a large part of where I think I went wrong. My partition system looked something like this: /dev/sta ... //SSD ~120 GB /dev/sta1 NTFS (350 MB) //Win8System /dev/sta2 NTFS (118 GB) //Win8C-Drive /dev/stb ... //HDD ~2TB /dev/stb1 NTFS (1563 GB) //FileStorage /dev/stb5 Free Space (300 GB) //Space I want to use for Linux (NOTE: Created two partitions from the 300GB, ~5GB and 295GB. stb5,stb6.) It'd be great if I could get an explanation of what drive you'd select for the boot loader and why, and what selections won't work with regards to the Boot Loader Instillation. I think I understand what Grub is, but I have no idea on how to use it, or play around with it. I seem to be able to get back into OS from my usb, however I believe it's just showing me a preview/trial of Ubuntu (ie, can't access any of the system NTFS drives). Note, if I try to install from the USB again, it will recognize that a version of Ubuntu 13.10 exists on the system. Apologies in advance, have used windows all my life, don't really know to much about Linux at all. Did have a brief skim over some similar questions, didn't find anything too useful. - Where to install bootloader when installing Ubuntu as secondary OS? - ubuntu 12.10 dual boot with windows 8 on two hdds - Dual-boot Windows 7 and Ubuntu on two SSDs with UEFI

• bootloader install failed

  - by user211860

  I have lenovo u510 with windows 8. This ultrabook has 24GB SSD and I tried to install Ubuntu 12.04.3 in it. I changed bios from UEFI to legacy and I used a LiveDVD. I created a 17GB partition when I was in windows from this SSD and I tried both manualy or with the "install alongside" but was allways without success because bootloader install failed and was unable to install GRUB. I tried also to use the "recommended repair" from Boot-Repair but it says that my laptop can only with UEFI boot. I changed it but the same thing happens my laptop boot in windows 8.

• Uninstall ubuntu from external hard drive + remove bootloader from internal hd

  - by Bart Sleeuwen van

  I have created a bootable usb stick with linuxlive and Ubuntu.I then tried to install ubuntu on my external harddrive. However I guess I wrongly picked the drive where the boot section is installed, it now is installed on my internal (C:) drive. When I open the bios bootsequence it says Ubuntu 2 times? As if the boot is installed twice? I'd like to uninstall Ubuntu from my external drive but most important: I don't want Grub to be start up on my PC. I tried booting in Windows 8 recovery mode and used the following commands: bootrec /fixmbr bootrec /fixboot However the ubuntu choices wont disappear? I then tried to add bootrec /scanos and bootrec /rebuildbcd to the commands but somehow this wont work either. Anyone got some ideas? Thank you in advance! Best regards, Bart

• Ubuntu - prettier bootloader

  - by Matthew

  I hate how when I turn on the computer it just (after the hp logo, which I hate having also), shows white text on a black background. I'm wondering if there's easy ways to customize this (I'm choosing between Windows 7 and two separate Ubuntu 10.10 installs). I've read a little about some complicated ways to do this, but is there not some simpler ways by installing a package on ubuntu or something? I don't want to hack a bunch of code together to get a simple effect. I'm hoping for actual images and having like the windows 7 logo and ubuntu logo to choose from. Ideas?

• Selected wrong OS from bootloader settings and now can't do anything

  - by Eric

  I'm trying to help a friend out with an urgent issue he is having. He has two Windows 7 installations when he was starting up his computer so the bootloader menu was making him select an OS every time he restarted. One installation is functional and the other is not. He wanted to make it so that he did not have to select the correct OS every time he booted up. He chose the wrong (non-functional) operating system in the windows settings and set the time to select an operating system int he bootloader menu to 0 seconds. Now, his computer attempts to boot into a non-working operating system and he has no way of selecting the correct operating system so that he can fix his mistake. What can he do to get into the functional OS so that he can fix his mistake? Thanks so much.

• Hidden bootloader

  - by Jack

  I need a bootloader that will work as described: I want my computer to boot Windows, that is my main OS installed on a primary bootable partition. However, I'd like to have a 2-3 second span with blinking cursor, before Windows starts. If I press any key in that period it should launch Ubuntu from a small Truecrypt-encoded partition, upon providing a correct password. In other words I'm looking for a hidden bootloader that would expose itself only when a key is pressed during a certain time. Do you happen to know anything like that?

• Call 32-bit or 64-bit program from bootloader

  - by user1002358

  There seems to be quite a lot of identical information on the Internet about writing the following 3 bootloaders: Infinite loop jmp $ Print a single character Print "Hello World". This is fantastic, and I've gone through these 3 variations with very little trouble. I'd like to write some 32- or 64-bit code in C and compile it, and call that code from the bootloader... basically a bootloader that, for example, sets the computer up to run some simple numerical simulation. I'll start by listing primes, for example, and then maybe some input/output from the user to maybe compute a Fourier transform. I don't know. I haven't found any information on how to do this, but I can already foresee some problems before I even begin. First of all, compiling a C program compiles it into one of several different files, depending on the target. For Windows, it's a PE file. For Linux, it's a .out file. These files are both quite different. In my instance, the target isn't Windows or Linux, it's just whatever I have written in the bootloader. Secondly, where would the actual code reside? The bootloader is exactly 512 bytes, but the program I write in C will certainly compile to something much larger. It will need to sit on my (virtual) hard disk, probably in some sort of file system (which I haven't even defined!) and I will need to load the information from this file into memory before I can even think about executing it. But from my understanding, all this is many, many orders of magnitude more complex than a 12-line "Hello World" bootloader. So my question is: How do I call a large 32- or 64-bit program (written in C/C++) from my 16-bit bootloader.

• Windows 7 won't boot from any bootloader except for Windows Boot Manager after partition resize

  - by user2468327

  I have a triple boot system on a single SSD: OSX, Windows 7, and Ubuntu. I use Chimera (basically another version of Chameleon) as my bootloader. Usually I can boot all 3 OSs without any issue, but after using GParted to make my Ubuntu partition 2 Gigs larger, Windows 7 throws me an error when trying to boot to it from either Chimera or Grub. The error is consistently: `0xc000000e can't find \Boot\BCD" (slightly paraphrased). However, I can still get into Windows by selecting Windows Boot Manager from the boot options in my BIOS. I've already tried several known fixes for similar issues, including bootrec /rebuildbcd (and variations), and BootRec.exe/fixMBR + BootRec.exe/fixBoot. I've also tried Chkdsk. At best this has made it so Windows 7 boots on its own by default (making me have to reinstall Chimera and change back my boot settings in the BIOS). At worst this made it so Windows won't boot period. Now I'm back full circle where I started. A detail that might be useful is that bootrec /rebuildbcd says that the number of found Windows installations is 0. I'm fairly certain that I don't have a hybrid MBR. Mainly because I have a UEFI BIOS, and with that, it appears each OS can support a GPT. So it would kind of pointless to have and deal with. I may be wrong though, I couldn't find any way of finding out for sure online. However, I know for sure that the version of Windows I have installed is the UEFI version, as well as every partition tool I've used to look at my boot drive tells me it's GPT. How do I get it back so I can boot Windows 7 through another bootloader so I don't have to manually select it in the BIOS? Preferably without a reinstall.

• Repair GRUB bootloader for multiboot system

  - by user1715324

  I have two hard disks – one a 1TB and the other a 250 GB. I installed the OSes in the following order: Windows 7 on the first hard disk (1 TB) After that Kubuntu 12.04 on a partition (/dev/sdb7) on the second hard disk (250 GB) The second drive also contains an NTFS partition. Now, kubuntu's bootloader was installed on the second hard drive's MBR (and successfully detected Windows 7). So, whenever I wanted to load Windows I used to select the first hard disk from the BIOS boot menu and the second hard disk whenever I wanted to load kubuntu. I know I could have set the second hard disk as the default drive, still I prefered this method. The problem started when I installed Linux Mint 13 on the second hard disk (/dev/sdb3) and overwrote kubuntu's original MBR. Now, the GRUB just detects Mint and Windows. The MBR on the 1 TB hard disk is untouched. Is there a way I can modify the MBR on the second hard disk now so that it will show kubuntu and Mint both?

• Restore Windows 7 bootloader after Windows 8 install

  - by JMK

  I have installed Windows 8 onto a partition after Windows 7, and when I turn my PC on, Windows 8 basically loads completely, and then I get the option to choose my OS. If I select Windows 8, I go straight to the lock screen, if I select Windows 7, my computer completely restarts and then boots into 7. I want to use the Windows 7 installation DVD to restore the Windows 7 bootloader using the method described by the How To Geek but I am worried that if I do this, Windows 8 won't boot. Can anybody advise on whether or not this will work, and if not how can I go back to selecting the OS right after the BIOS loads?

• Install GRUB bootloader without installing Linux.

  - by Kavitesh Singh

  I have Windows 7 installed on the system and I want to create a separate WinPe bootable partition which system can fallback when things go wrong. Now Win7 does give this option and i might also edit the BCD store to make changes in the boot menu of Win7 or could use EasyBCD. I dont want to use these options as i need to customize hiding/unhiding of partitions at the time of booting etc. I search and found GRUB might the tool i am looking for. I want to use GRUB loader without any version of Linux installed on the system. Can someone guide me how i can install the GRUB on harddisk MBR and configure the bootmenu. I search internet and mostly i came across commands which search the GRUB on the harddisk because of existing linux installation and then try to repair it. In my case there is no Linux at all. I have Ubuntu 9.10 bootable CD/ OpenSUSE 11.2 liveCD and installation disc. Can i use them to install GRUB on my system?

• Access Existing Linux Installation from Windows Bootloader - Linux Installed and Then Windows 7

  - by nicorellius

  My hard drive is failing. I installed a new drive, and the installed Ubuntu 12.04 to try to rescue data. Realized that I wanted to install Windows and just access drives without transferring data (there are loads of it). I then installed Windows 7. Now my drive only boots to Windows 7. How do I access Linux and make Windows boot-loader load Linux? I originally thought I would just not use the Ubuntu installation but now I think I want it to be a dual boot system. What are good boot-loaders to install for this kind of dual boot situation? Can I accomplish this with BCDEdit? If I would have done this the other way (Windows first, then Linux) everything would be fine, but I didn't and now I'm trying to fix this. The problem I have is that I don't really know how to boot into Linux to retrieve any files I need. I guess using the disc would work, but I'm not sure how to go about this.

• How to change windows bootloader target folder

  - by ST3

  Here is described part of windows boot process. I would like to ask if there is a way to change boot folder, I mean to use something else instead of C:\WINDOWS. And of course that something else is a copy of Windows directory. It looks like bcdedit is good for that purpose but I'm not sure how to use that. That I want is to change path, which currently is \Windows\system32\winload.exe to \Windows Copy\system32\winload.exe Another thing I have found out is registry, HKLM\BCD00000000\Objects\{df90fe29-c40d-11e2-a7bb-92410b6e649d}\Elements\12000002::Element value is \Windows\system32\winload.exe so changing this also may be promising. But I'm not sure if I should change registry value and don't know how to use bcdedit, so any related help will be appreciated.

• How can I reinstall GRUB Bootloader on MBR after installing Kubuntu?

  - by Agnes

  I installed Ubuntu, but then installed Kubuntu over it (formated Ubuntu Partition) because Ubuntu is not compatible with almost any hardware on my PC. Problem is I'm stuck with an old GRUB that says Ubuntu in the options because in my attempts to make it compatible with my hardware I got an old Grub with an image with an Earth that says Debian. How can I replace the GRUB with the one Kubuntu is supposed to install. I don't want to modify just the text, or the command to install on /sdaX, I want to actually re-write the MBR with the latest grub (reinstall the bootloader). Thanks.

• How to move the Windows 7 bootloader to the Windows 7 partition?

  - by pauldoo

  I recently installed Windows 7 in a triple boot setup alongside XP and Linux. When I was finished and was in the process of restoring the bootloader for Linux I discovered something strange about what Windows 7 had done. I discovered that Windows 7 had not installed a bootloader to it's own partition, and instead had instead set up a bootloader on the pre-existing XP partition that offers a choice between 7 and XP. This behaviour has been noticed by others. Now my booting is slightly odd. I have GRUB on the MBR which lets me choose between Linux and Windows. When I select Windows I have Grub boot to the XP partition where I get the 2nd choice between 7 and XP. Why doesn't the Windows 7 installer put the Windows 7 bootloader on the Windows 7 partition like all previous MS OSs? This is now going to be a real problem for me, as I now want to wipe the XP partition and install something else there (probably another non-MS OS). How can I move the bootloader for Windows 7 onto the Windows 7 partition, thus making it bootable and allowing me to safely wipe the XP partition?
