Software :: GRUB Won't Boot From XFS Partition Gives Error 21.
Apr 17, 2010
GRUB (0.97) won't boot the XFS partition that holds my new Arch Linux install, instead giving an error 21. I am able to boot my system using GRUB on the Arch Linux install CD - having to manually edit the commands each time.
This holds even after I updated all software and then reran setup from the grub shell. I made sure to install to the MBR not the partition (the latter I believe trashes XFS).
Googling has found some mentions of trouble, but nothing that seems to clear on how to resolve the issue.
Changing filesystem is not an option - I installed Arch on a drive that already contained all my data. (Which is all fine, I made sure not to format it

I have a netbook that dual-boots Win XP and Ubuntu 10.04 and accidentally hit the Win recovery mode in GRUB today, but quickly restarted without formatting or proceeding with any recovery. But upon reboot I just see: error: no such partition. grub rescue>
What I have tried so far: Boot to USB Live Disk... It won't, just goes straight to grub rescue.I do ls and it gives me (hd0) (hd0,4) (hd0,3) (hd0,2) (hd0,1) (fd0) error: fd0 cannot get C/H/S values.
set gives me
prefix=(hd0,5)/boot/grub
root=hd0,5
but if I try to boot it says unknown command so I figured I needed to find the right partition to boot from but I went through all of them with ls (hd0,4)/boot, ls (hd0,3)/boot etc. and every partition comes back "unknown filesystem".

Just delete a linux partition and now when i boot a message appears and says error: unknown filesystem grub rescue >
I have search on the net for this problem and i have understand it a little. But my situation is a bit different and because i don't want to format my hard disc i wanna try to fix it. So before a couple months i download ubuntu 9.10 and i installed it a month later. But my computer used to crash all the time and i couldnt use it. So i download the latest ubuntu 10.4 and install it while having windows xp and the old ubuntu 9.10(so i had windows xp, ubuntu 9.10 and ubuntu 10.4 partitions). Now i tried to delete the partition of ubuntu 9.10 from disc utility. so i have the message i wrote above when i boot. I dont wanna delete my windows xp and ubuntu 10.4. what should i do to stop this message from appearing.

I have an ML570 G4 with a P400 array card. Ubuntu server 10.04. I added more drives and extended the size of the partition to 2048gb. Now on boot I get Grub Error 18. The live cd sees the partition I just cannot boot it. I've googled around quit a bit,but have not found much that is relevant. I believe I am going to be adding a smaller boot partition to the beginning of the drive to fix this

I am new to Linux. I have installed RHEL 5.4 on my PC with preloaded Windows XP.
Windows was set as the first boot kernel. So if i do not choose which OS to be loaded it will load Windows by Default.
Today I got an error saying GRub Loading Stage2 read error.

I dual booted ubuntu with vista a while back, but I was running out of space on both partitions. So I thought I'd install ubuntu on another slightly smaller HDD from an old laptop. I thought all the ubuntu and grub stuff were on that one partition, so I thought if I just deleted it, all would be good. I isn't. Now when I boot up, I get a message saying 'Error, no such partition exists' and then 'Grub rescue:' and an input. So what I want now, is well, basically to be able to boot windows. I'm guessing I either have to remove grub, or just make it forget I ever had Ubuntu.

I got ubuntu 10.04 lucid lynx along with windows (dual boot) and using Grub. On my computer, I have my C:/ (programs) and D:/ (data). I've never used my D:/ before that day that I've lost my windows partition on my grub menu. I usually use my D:/ with windows. The first time I used my D:/ to store data with linux, I lost my windows option in my grub menu. I'm not sure what I did wrong but I do want to restore my windows option in my grub menu.
After "fdisk -l",
I checked in /boot/grub and there is no menu.lst to modify. how I can get back my windows option in my grub menu ?

I having a problem getting my grub loader to see one of my hard drives. I added a drive, and my grub loader lost track of where everything was. I couldn't get my old linux (Red Hat 9) so I installed SuSe on my new hard drive. But I need my be able to boot from my old hard drive because it has apps that only run on the earlier version. From /proc/partitions the old hard drive is sdd

I am trying to install a box here where my /storage partition is about 2.5T.I had setup the partitioning with suse, while testing, and all worked well.Now when trying to install CentOs 5.5 it gives me an error, that my boot partition is on a gpt partition and this machine cannot boot that.Also I don't see the option to create XFS partitions from the installer.Can 5.5 support GPT @ install time?

is it possible to use a Windows-based recovery partition on a dual-boot computer to overwrite the Ubuntu partition and remove the GRUB loader? For instance, if you booted up your computer, accessed the hidden recovery partition and used it to reset the computer to it's factory default settings, would that effectively remove the Ubuntu partition and the GRUB loader? Would a completely new installation of Windows overwrite/uninstall Ubuntu and GRUB automatically?

I updated yesterday and now when I start my laptop it goes in to grub rescue mode. I have booted from a 'live cd' and thought I could repair grub from there. In gparted however the partition with ubuntu (sda1) is seen as unknown file system, in terminal when I list the partition table it shows up as FAT16 type. When I try a grub-install it gives this error message:

I dual boot windows xp and ubuntu 9.10 UNR on my asus1005ha Netbook What happened: I deleted the ubuntu partition and the swap partition through windows xp using Disk management. Whats happening now : When I power on my netbook grub says the following GRUB loading. Error: no such partition grub recovery>. I attempt to input any sudo command it says unknown command which makes sense considering the partition no longer exists.

I resize my Ubuntu extended partition in Windows and now when I boot, I'm getting a GRUB rescue and the error "no such partition". I'm on a LiveUSB. Here's the results of my fdisk -l:
Code:
omitting empty partition (5)
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders[code].....
The first device is my hard drive: the second is the LiveUSB and the third is an SD card I have to move files to.I ran a fsck on my Ubuntu partition, and I can't seem to mount it (or the Windows one): it gives me the error: "Message did not receive a reply (timeout by message bus)".How could I recover my data on both the Windows partition and the Ubuntu one?

I was and idiot and stared messing around gparted before I was ready to partition my hard drive. Consequently I messed up my partitions, and when I restarted my computer a screen comes up that reads:
GRUB loading.
error: no such partition

Have I killed my computer or is there some way I can fix it?

I know this is a common error, but my situation is a little different than previous threads on this issue and I just want to make sure I get the correct solution.
Basically, I had Ubuntu 10.04 and Windows 7 on my netbook and wanted to try a more lightweight version of Ubuntu. After settling on LXDE for a desktop, I decided to install Lubuntu 10.04. I chose not to install LXDE over regular Ubuntu because I wanted to eventually end up with an Ubuntu distro with either GNOME or LXDE, but not both. So rather than put myself through the hassle of uninstalling all the GNOME or LXDE packages, I decided to keep them each on separate partitions.
In the end I decided to just stick with regular Ubuntu and deleted the Lubuntu partitions. Now I get the GRUB error written in the title of this thread.

I'm using an Eee netbook so i have no CD drive. I've used Linux for about a week. Someone else installed it for me using their flash drive. If I need to use a flash drive to install I will need info on how to install to a flash drive. I had it set up so i could choose windows or ubuntu at start up. logged into windows to play a game and all it brought up was.
GRUB loading.
error: no such partition
grub rescue>
Now that's all I get when I turn it on.

Ubuntu 9.10 was set up to handle the booting selection - previously I thought it was xp but Ubuntu 9.10 "did" it. The system started out as a xp / ubuntu 9.10 dual boot on a 400gb drive. xp has 210gb, ub has 80 and their is a 100gb shared storage. Xp was installed first and then I followed a guide over at linuxconfig.org to get ub installed so that I could select which OS was wanted at boot. Ubuntu manages the boot up menu (Went back to look at my notes from the original setup) The owner tried to update to ub 11.04 and afterall was said and done the machine now boots to the message
error file not found grub rescue I can't say if 11.04 was properly installed or not. Ask whatever you like and I'll give the best answer I can. I think the xp install is okay but I can't say for certain as I don't know how to boot it outside the bootmanager at startup. Data has been saved so if I have to blow it all away and start over I can but I'm hoping I won't have to.

I'm a Windows 7 user attempting to install openSUSE in a partition on a separate hard disk, and am receiving grub error 17 on install. My windows partition is sdb1, and my (hopeful) openSUSE partition is sdc2. When I attempt to redefine the grub config after receiving the error message, there are no mounted drives in my "/dev/" folder to point to, nor can I find the kernel image or RAM disk in my "/boot/" folder.

I have a machine with two disc but only one is involved in the boot. It is hd0 / sda. On this I have several partitions, first I have a partion (sda1) with grub-legacy and a menu.lst file that boot by chainloading my ubuntu 10.04 on partition sda4 (with ext4 and grub 2). This works without any problems. Today I was doing a larger upgrade of my mythtv install so I first copied sda4 to sda3, did all the neccessary changes in /etc/fstab and a grub-mkconfig (so that the grub.cfg on sda4 also included sda3 kernel). The chainload manage to nicely chainload to sda4 and when I select the newly copied kernel on sda3 it boots. Now inside the booted kernel/ubuntu on sda3 I again do the grub-mkconfig so I get a correct grub menu. I add a new chainload to menu.lst on sda1 so that I can go direct from that to my new partition.
when I chainload to the sda3 (hd0,2) partition I get grub-legacy error 13 invalid or unsupported executable format. No grub2 menu from sda3 shows up and the boot halts. The grub.cfg files on sda3 and sda4 are identical besides the uuid and hd0,3/4 references.

I had 3 partitions on my hard dive, Windows 7, Ubuntu, and just junk on the other. I installed Ubuntu in a way where it went to the GRUB filesystem? first, where it ask me to start in linux kernel 2.38.6 (can't really remember the kernel exact name) which was ubuntu, some other options, recovery mode, and at the very bottom was the one to go to Windows 7. I was in Windows and I wanted to get rid of my junk partition but I formatted the Ubuntu partition by mistake.
Now when it boots up it saying:
Error: unknown filesystem. grub rescue>
I hope there is a way to save my files on Windows. I tried to reinstall Windows 7 back on my computer but it wouldn't go through since the grub startup thing is the main one, not the windows one.

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
