I've been working with ubuntu now for quite some time. My computer loads grub fine on a cold state boot. It loads fine on my 3 linux based systems when they restart. It gives me a grub 21 error when I choose restart in windows 7. I'm forced to press the power button, and turn it back on- not a huge deal, as its a 100% fix. I'm already booting with rootnoverify, and have checked the command on boot to make sure it was the right grub menu that was installed. I also couldn't find a topic with a problem like this, most were just grub not working at all after install or similar.
After lots of searching last night I noticed that over the last couple of days there have been quite a few posts of people receiving the error: no such device lots of numbers grub rescue>. I have a dual boot vista/ubuntu setup with ubuntu on my d: drive and windows on my c: drive and it happened to me last night. So after my freaking out when I received the grub rescue> error after updating somethings in my ubuntu install and restarting. Once the computer rebooted bam! error. after much freaking it only fixed itself by reinstalling the windows bootloader via the vista rescue disk I was wondering if there was a way to prevent this from happening again? will ubuntu attempt to "update" itself again?
I have two partitions installed on my computer, Ubuntu 10.04 (part. sda2) and Windows XP (part. sda1). When I restart my computer I get this message: error: file not found grub rescue>
I thought this must be a grub error, so I booteda Super Grub disk (v 0.9799). Then I tried to fix grub with the Super Grub disk, but I got this message: Error 15: File not found Booting 'not lucky' pause SGD has NOT succeeded SGD has NOT succeeded
I then booted the system using an Ubuntu live CD, version 10.04.I tried to repair the sda2 Ubuntu partition. At a terminal prompt I ran [code] sudo e2fsck -f -y -v /dev/sda2. This did not work. It ended with "e2fsck aborted". I could not repair the Ubuntu partition, I tried to open the sda2 partition by running the terminal command [code] sudo mount /dev/sda2 /mnt. I received the following message:
mount: wrong fs type, bad option, bad superblock on /dev/sda2 missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
Using the ntfs-config program, I can easily mount the Windows XP partition (sda1). It mounts and I can read or write the files on the Windows XP partition. So at least Windows XP is not damaged. I downloaded and ran the boot info script, and here are the results:
Code: Boot Info Script 0.55 dated February 15th, 2010 => Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in partition #2 for /boot/grub .....
when it comes to linux, but like the idea and hope one day to get away from microsoft all together. This is the second time I have tried to install ubuntu on my eeepc 1000HG in addition to windows 7. The first version was karmic koala netbook remix, and yesterday it was lucid lynx netbook remix. Its annoying because before the update packages are downloaded and installed it runs smoothly, even additional applications run with no problem, but after restart to complete installation the following error message appears.
error: no such device: 5290ea6f-1bdf-4eda-b56e-2f282662e188. grub rescue>
I have windows vista. i tried installed linux-ubuntu 9.10 but not knowing after a point on how to proceed further, i quit half-way. so my partition (14 gb)remained wasted. i tried installing again in a new partition and got it done. from my newly installed lunux, i tried to delete that 14gb partition. and now when i restart my laptop, i get this error :
I installed ubuntu today by installing Wubi and after downloading i rebooted computer and selected ubuntu but i got an error saying 'Try (hd0,0): FAT16: NO WUBILDR' and there was few more but i forgot and at the end it says 'Cannot find GRLDR in all device Press CTRL+ALT+DELETE to restart'. it used to work when i had vista...
I dual booted Ubuntu with Win XP, and decided to upgrade XP to Win7. Thought I knew how to do it, so excuse my dumbness. Here's where I'm at: I booted GParted, and deleted the /, /home and swap partitions, making unallocated space. I expanded Win XP partition and tried to re-boot, expecting only Windows to show. Instead, I got the Error 22 error when Grub was the first thing to load. So, back to GParted, deleted the primary partition, created a new bootable partition, formatted it NTFS, and put the Win7 disk and rebooted. This time I got a Windows error "can't load NTLdr".
Rebooted the computer without the disk, and got the Error 22 again. So it seems (?) that I'm not able to change/remove or otherwise, the Grub boot file. So the drive is currently useless, unless someone can tell me how to get the disk back to a bootable state where I can load Win7, after which I can create Ubuntu as a dual boot again.
I've been serching the forum for hours and every thread related to "GRUB error: no such partition" that i've read relates to fixing the issue for users with windows OS also installed or trying to get windows to boot.
How it happened: I edited partitions and now I get GRUB error: no such partition. I ONLY have Linux installed.
I was able to boot the OS by typing:
Code: set partition=(hd0,1)/boot/grub set root=(hd0,1) insmod normal normal
I just got a new computer that has Windows 7 Ultimate, and I want to install Ubuntu to a partition that I created. I want to be able to re-add my Windows 7 to the GRUB, without erasing either of my operating systems. I have seen people that changed the menu.lst file, but got the BOOTMGR not found error. Will I get this problem? My computer came with one drive split in two partitions, WIN7 and DATA. I took 150GB out of the DATA partition to make a new one called Linux. So, how would I put Windows 7 in GRUB, but not erase eithr operating system, and will I get the BOOTMGR not found error?
I am having trouble getting a dual boot setup on Ubuntu remix on a netbook. The install went fine, but then windows would not book. I had a windows error. So I reinstalled windows, and rebuilt grub. Now when I try to launch windows from the grub menu it says "error: no such device: 0a82ff1982ff0849". How do I go about fixing that? I can boot to Ubuntu fine now.
With a bit of help from this forum I managed to install 10.04. The solution was to add i915.modeset=1 to the options when booting up from CD.Now I need to do the same in order to boot up from HD. I've opened /etc/default/grub and changed the relevant line to include the above option. But I need to run "update-grub" and it comes back with an error to the effect that it 'can't find a device for / (is /dev mounted?)Also, the boot menu only has ubuntu - no sign of windows in my intended dual-boot. What can I do?
I installed Backtrack 4 and it is set up as a dual boot with my Windows 7 x64 bit. I want to uninstall Backtrack because I am going to put it on a different computer. The problem is - I can't do it. My laptop is an Asus K61IC, and it doesn't come with an installation CD, because the OS was factory installed. It comes with a recovery wizard instead, which gives me the options to 1) recover to first partition only, 2) recover to entire HD, and 3) recover to entire HD with 2 partitions. Because of Grub and it asking for me to choose what operating system to boot when I start my computer, when I recover Windows 7 to the entire HD and try to boot, it gives me Grub error 22. I need to fix my MBR so that the grub menu is also deleted and all of Backtrack 4 is removed, actually letting me back onto my Windows 7. I need a way to delete the Linux partition, and fix the MBR, but I don't know how to do that because I don't have an installation disk.
When i tried to install windows xp and ubuntu 9.04 together i got an error as GRUB 18. Then i installed only ubuntu 9.04. Now i am planning to have both ubuntu 9.04 and fedora 12 on my system. Is it possible that i'll again get the same error? If yes what are the possible solutions?? and is it advisable to have both fedora and ubuntu in the same system??
I installed Ubuntu as a dual-boot system with Windows XP very carefully. Unfortunately, though given the option to boot Windows at the grub menu, when I select it, I get an error. Booting Ubuntu on my other partition works just fine, no issues.
I also attempted to access files from the first partition in Ubuntu using gparted, but once I mounted it, all of my files were not present. I only saw manufacturer files, and many files and folders I didn't recognize.
Also, as an aside, my laptop monitor is suffering from occasional black-outs during use. Ubuntu gave me a little toolbar flag, telling me to go to a website and use the patches given to fix it, but I'm not quite so sure where to input the given patch text. Do I really need to go through the trouble of finding the source code, etc., or is it more simple?
I have a dual boot System with Ubuntu 10.04 Netbook Remix and Windows XP SP3 on an Asus eeePC 1000HE. I had some troubles with updating kernels etc. and I ended up with following problem:
After grub reinstall, I am able to boot Ubuntu, also I can mount the windows partition properly. Trying to boot into Windows, I get the error:
Code:
It's all on one hard drive which doesn't show any errors:
Code:
Partition table entries are not in disk order
Code:
Some partitions don't show a file system because they are luks-encrypted.
As I mentioned earlier, I am able to mount sda1. I think the problem is that the Partition Boot Sector is corrupted, even though I am not sure if the ntfs partition is damaged at all or if GRUB is the problem.
As I said I had problems with a kernel update and therefore had to reinstall GRUB. I think, but I am not sure, that I accidentally installed GRUB on sda1 (the windows partition) instead of on sda. After I installed GRUB on sda again, I was able to boot linux and fixed sda1 with testdisk. Before, sda1 showed as four partitions (sda1p1, ... , sda1p4). I was not able to mount sda1 till I fixed it with testdisk. testdisk says the Boot Sector of sda1 is OK, so does ntfsfix.
Finally, an extract from my /boot/grub/menu.lst:
Code: ...
The Windows XP entry is added by myself. I don't know much about grub, so there might be the error.
I tried to keep it as short as possible (this is only the end of the story), I hope I didn't forget anything important. Please ask if there is something not clear.
I am in Tanzania with this netbook, so it is not possible to boot Windows CD and fix the windows partition with it, also I don't have a very fast Internet connection.
Is there a way to fix this without a Windows CD? Maybe it is just a dumb mistake in the menu.lst?
I know its not a Linux program but my brother had Linux on his HP DV9000 Laptop, Well he wants to go back to windows XP home edition or what ever, he played around with it and messed something up and when you boot it, it comes up with a GRUB error 22, so I try to boot it with the windows XP CD and when i try to install windows or repair it tells me there is no hard disk... which seems kinda stupid considering your PC needs a hard disk to boot up, so in the BIOS menu i did the hard disk testing and what not and it came back 100%...
I have two partitions on my HDD. A Windows XP (hd0,2) and an Ubuntu 9.10 (hd0,1).I have been using the Windows mainly and ran a program that changes the HDD's serial number. Now when I boot up and Grub loads, I try to access the Windows partition and get the following error:
Error: No Such Device: 2e3857fb3857c08f
I am still able to boot the Ubuntu partition but can not seem to get grub to point to the Windows partition any more. This is very frustrating as I really need to get back into that partition soon.
I believe i no longer have Vista. I had installed 10.04 side by side with Vista. Now that we have 10.10 i wanted to do a fresh installation on my laptop. I wanted to do the same thing, install it side by side so what i did is i installed gparted and tried to erase/delete ubuntu 10.04 and leave windows on it. From what i remember, i did just that. I restarted my laptop and windows didnt come up...i got a grub error...i decided then to install ubuntu 10.10. i selected to install ubuntu side by side again with vista. During the installation, i received an error about a partition...i made a few clicks...after it was installing and it went smoothly.
Now when i restart my laptop...it does not give me the option for windows....how do i know if i still have windows on my laptop? According to Gparted i dont have it anymore...
I have a dual boot system with ubuntu 9.10 x64 and Windows 7. Everything has been working fine for a a long time but yesterday I tried to delete an unused partition through the Disk Utility in ubuntu (System->Adminstration->Disk Utility) and everything was messed up. I used to get the "Grub error: Unknown filesystem". I managed to create an ubuntu bootable usb and followed some tutorials for fixing grub but all i managed to do is to get another error: "Grub error: No such disc". After some experimentation i got "Grub stage 1.5" which gave me a grub> command prompt./dev/sda is the drive containing Windows and Ubuntu.
Code:
[ Boot Info Script 0.55 dated February 15th, 2010 ============================= Boot Info Summary: ============================== => Grub 0.97 is installed in the MBR of /dev/sda and looks on the same drive in partition #6 for /boot/grub/stage2 and /boot/grub/menu.lst.
i have just discoverd i can't enter my windows 7 via grub boot menu i get error 13 Invalid or unsupported executable format what can i do? # This entry automatically added by the Debian installer for a non-linux OS # on /dev/sdb1
I had a working dual boot Ubuntu 10 and Windows 7. Anyways long story short, I got it working again but have lost the boot option for windows 7. If i run fdisk -l, I get the following.
I installed gparted and can see that windows 7 is installed in dev/sda6. In another forum, i read that someone had to edit their menu.lst so i did with the following.
Just attempted to upgrade from 10.04 to 10.10, after having updated everything. Upon completion of the upgrade I was asked to restart, however, when I restarted the PC I was presented with the following: GNU GRUB version 1.98+20100804-5ubuntu3 Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions.
Background: My mother's HP laptop had Ubuntu and Vista on it, Ubuntu my brother's doing. He decided he wanted to take off Ubuntu yesterday (he had forgotten the password), and deleted the partition that it was contained within. The computer now boots to this error.
Inventory: We no longer have the install disk for Windows Vista, he cannot tell me what version he used of Ubuntu, what partition it was on, any of the specs for the machine, or generally any information about the system. All I am aware of is that error on the boot-up screen. I have nothing else to work with.
I would like to remove Grub, and Ubuntu, and leave Windows intact (the request of the owner of the computer), but I have no idea what commands I could use to get rid of either when I can't access Windows, or how to properly remove them if I did access Windows.
I just installed Ubuntu 9.10 on hd1 - /dev/sdb1 at the end of the installation I chose to install grub at hd0 - /dev/sda1. The file system I chose was ext4 for ubuntu "/" - 50 GB, ext3 for "/home" - 5 GB, and 1.5 more for swap. When the installation was complete I got the following prompt:
GRUB loading error: no such disk grub rescue> >
There was nothing I could do, pressing TAB did not show me all the commands like grub is expected to. Typing 'help' did not show any commands as well, instead it showed me - "NO SUCH COMMAND" or something like that (I did not took note of what the output was). I believe the problem is in the grub loader - which was not really installed properly in hd0 - /dev/sda1 (which is FAT32 - windows)
I have a dual boot PC with Windows Vista and Ubuntu 9.1. The problem did start with Ubuntu 9.04. I think the problem started around the same time I added a Seagate FreeAgent USB hard drive for backups. The GRUB OS list will come up after the PC boots. I can select Vista and it will start w/o a problem. If I try to boot to Ubuntu the PC will restart itself. It may try and start Ubuntu MANY times until it eventually gets started. I have tried to repair the problem with no results so far. I have tried it with and without the Seagate device attached.
i was working on ubuntu when the machine suddenly shutdown. when i restarted it, i keep getting a sh:grub console instead of the logon screen. dunno what to do.
