A formerly working system now gives an 'error 17' at Grub instead of booting. Here are the facts I have gathered thus far.
$ blkid
n/a (no output)
$ sudo fdisk -l /dev/sda
Code:
Disk /dev/sda: 60.1 GB, 60060155904 bytes
255 heads, 63 sectors/track, 7301 cylinders

I just loaded octave. I ran through a few examples of how to implement a script file. Everything works until I get to "plot". When I run the "plot" command I get the following.
octave:2> test1.m
error: can't perform indexing operations for <unknown type> type
sh: gnuplot: not found
Just to double check my work, I ran the following code:
y=[1 2 3];
plot(y);
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 am doing the DNS configuration for the first time. Error in named configuration:

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.

i have FC10, and have loss my grub because a windows 7 instalation (other partition). I am trying to re-install the grub version 0.97, so i used:
FC10 DVD install + repair a system
then:
Code:
chroot /mnt/sysimage
grub
but i got:
unknown partition table signature.
so i can not make any grub command:
Code:
grub> find /boot/grub/stage1

I am not able to access the harddrive. I am very new to ubuntu.
I have been using ubuntu 9.10 for a month. i have it installed on a 5GB separate partition of a 80 GB hard disk with my XP installed on a C drive(a separate partition ofcourse) then i had to remove it from my PC so i boot my PC with a partition manager cd and directly formatted that partition of 5GB from that software now i am having this error on my boot of PC....
grub rescue> error:unknown filesystem
I have tried a lot of commands here on this screen and nothing happens...i want to go to my XP .... and can't loose my XP OS and other data as well on different partitions.....
there was ubuntu on my pc operating system but it is strange for me so i wanted to instal windows 7 on my pc. I inserted Window 7 disk and started to install it and i formated Ubuntu but the disk what i was using was damaged and it could not complite the installation and now i dont have any programs in my pc. Problem is that i got another disk but i cant boot anymore my pc, i select drive and stuff and then comes error.
error: unknown filesystem grub rescue- i tryed different commands but those didnt worked.
I had dual boot with windows 7 and ubuntu 10.04 running, and working. In my grub menu on startup I could choose (among things) something called Vista loader. Dont know why, since I installed windows 7 and not vista. Could also choose windows7 and ubuntu, both worked.
Today I accidentally pressed the vista loader, and now I get the following error upon boot: Error unknown filesystem grub rescue
So the next thing I did was download the latest ubuntu and boot from live cd. I followed instructions [url] on how to purge grub2 and reinstall it, and did so with out any problems. However the same error remains when I boot.
I just recently decided to install Ubuntu alongside windows 7 64bit. I was working fine until I decided to increase the partition size of the unused space to take up some space of an unused partition I had made earlier. When I tried to reboot windows I got the error -
error: unknown fileystem.

I have tried a windows repair disc with no results, it cannot find any problem with the startup routine and I have looked at many different tutorials and information about how to restore grub using command from the grub rescue menu. Ubuntu 10.10
i installed ubuntu 10.04.. all very nice, but not the os for me.. lightscribe problems, front ir panel problems. minor niggles for sure, but enough for me to go ahead with formatting and installing windows. simple job...or so i thought... using windows set up, i formatted c: and continued with install...on first restart i got a grub error saying unknown file system... i have tried loads of different things... fix mbr fixboot, that nt60 one. dban wouldnt work either.. im at my wits end ive spunked the best part of 1000 on this system and my wife is nagging me.
View 4 Replies View RelatedI tried upgrading to 11.04 this morning and after rebooting grub left me at the grub rescue> prompt with the message 'error: unknown filesystem'. I've tried purging and reinstalling grub using a live-cd but no joy.
Let me know what additional information to provide. EDIT: Here is the output from the Boot Info Script

my ubuntu installation has stopped booting after i deleted and again created one of my partitions (not the ubuntu partition but my data partition). but now when i switch on my netbook it says: error: unknown filesystem grub rescue>
i used gparted live to resize. this is my disk partition structure:

before doing this, my ubuntu partition was /dev/sda7, the swap partition was /dev/sda 6, and the data partition was /dev/sda 7.
I have dual boot with Ubuntu 9.10 and Windows 7. Today, after using Partition Wizard on Windows to resize its partition, I got the following message when reboot:
Code:
I dont actually know what to do, I've been reading some threads on the internet but nothing equal to my case, only people who installed Windows after Linux and lost GRUB. Do I just need a live CD to reinstall GRUB? Can somebody tell what to do?
When i open my computer this message is coming what can i do?
grup loading error:unknown filessystem 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 :
GRUB loading.
error: unknown filesystem
grub rescue>
I would like to know what exactly has happened and how do i get this resolved.
I have a pc that was running with the latest version of ubuntu and i wanted to install just vista for somereasons.
And what i did is to format the main driver and try to boot it from vista CD and as you may guess i have an error that says: unknown file system grub rescue
Each time i start the pc. I have an ubuntu live cd and also the vista cd, so what should i do now? the vista cd dosnt boot and the same screen appears all the time.
I just installed ubuntu on my computer that already had windows 7 on it so I could dual boot them. After installing ubuntu and playing around on it a little I went back onto windows. I then restarted my computer and now it won't startup. I get an error that says unknown filetype grub rescue<. I don't know what to do to get back into windows or ubuntu.
View 4 Replies View RelatedI've recently installed Ubuntu 10.10--it had Windows 7 on the machine before but wiped that off so it is not dual boot.
The upgrade manager prompted me to install about 170MB or so of upgrades. I chose to install everything and then rebooted. Upon rebooting I received an error (sorry but didn't record it).
I rebooted by ctrl-alt-delete and then got the error: error: unknown filesystem grub rescue.
How do I get back my installation?

I am building centos - debian dual boot system. Each os has separate boot partition, both ext3.
Installed Centos 5.5 x86 with grub into MBR.
Installed debian 5.0.4 x86 with no boot loader.
Added debian to centos boot partitions grub.conf
Centos boots fine. When I tried to boot debian I got grub error:
Code:
Error 2: Bad file or directory type
Grub's command line auto compledion didn't work on debians boot partition - looks like it does't recognize that partition as ext3 (but when I booted centos and tried to mount debian boot partiotion - no problem it mounted ). And this is not single fs corruption - after another debian reinstallation the problem remained. Anyway recreating that fs using "mke2fs -j /dev/sdxx" solved the problem.
I'm running Debian testing and after a recent software update, suddenly I can no longer boot into my single Linux kernel image anymore. I did look at the software update before I did it and I don't believe that it removed any software packages. When I try to boot into my linux 2.6.26-1-amd64 image, I get the following message from grub:"error: unknown command `initrd'"..The same error appears if I try to boot into single-user mode. I have a Windows XP partition on the same hard disk and I am still able to boot into that from grub. I've searched the net and haven't really found my same problem replicated anywhere. I would imagine that the problem is just that somehow the initrd package got removed in my last software update, but again I don't recall seeing any software that the update planned to remove.
Any thoughts on how I would go about fixing this problem? Since I'm unable to get into Linux at all, I imagine I'll have to use a LiveCD to get in and fix the problem, but I don't know where to begin looking.
Yesterday I installed the latest version of ubuntu to my computer that was already running windows 7. I had everything working fine until in windows I deleted a partition that had nothing in it.
After this I restarted but I can't get into either OS. I get an error that says Error: unknown filesystem grub rescue>
I think I need to fix something in grub. I have been booting off of a usb stick with linux on it in the mean time.

If I could I would change the boot order but I can't do that (I have a Dell Studio 1747). I try F2 to enter the BIOS set up, but I still end up with that error and never get to the setup. F12 doesn't work either (F12 is for the boot order) so I can't boot from the DVD with the Win7 installation DVD as the computer just freezes and I can't get past the Dell splash screen.
I have tried to remove the coin battery on the motherboard in an attempt to reset the BIOS but that didn't work either.
So...
F2 = error
F12 = freeze
Reset bios by removing coin size battery = no change
I assume there is no use reformatting the HD by attaching it to another computer and re-install Win7. Is it a motherboard problem?
Yesterday my computer froze using ubuntu 10.1 so i turned the power off, then back on, now i get this message when trying to boot: error unknown file system Grub Rescue>
I tried fsck from a live CD but it doesn't work.
