Hi, 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:
error: unknown filesystem
grub rescue >
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? Thanks.
I have an idea to fix this!
You need to boot from ubuntu , you need to edit boot load ( grub ), computer is booting to grub edit it ! or create a new command line !
This is a template !
root (hd0,0)
kernel /vmlinux-version(you can table it ) ro root = /dev/hdaN
initrd /initrd-version
Now press ctrl+x to boot it .
sorry , my english is bad , so , I don't know do you know what I mean !
dit it work ?
in system you just to perfom a command : upgrade-grub(after I forget , you can table)
Well, thanks syg00, I reed it and found a a solution in the part about the rescue mode, had to manually boot to Linux and after it I re-installed grub.
Instead of hijacking other threads, although related, you should start your own thread. That way it'll get the attention it deserves.
In regards to your problem, have a look at this tutorial at chapter 8, it states how to repair GRUB2 and in Chapter 5 there's also a description of dual booting Win7 and Ubuntu.

Hello
When you have made some new partition or just move partition, you will changed the orden of your partition. That's why you get this error.
The easiest way to fix that is with SGD. This is a disk that will automaticly will fix grub for you. You can download it here: http://www.supergrubdisk.org/
And second way.
You have to boot live cd Ubuntu.
With
Code:
sudo fdisk -l
you have to look where Ubuntu is installed.
Then you have to mount it:
I'm very new to this forum and I'm a beginner at using Ubuntu. I am using my wife's computer with a Windows operating system in order to seek help on how to fix my computer that has I think the latest version (Version 10.0 or something close to that) of Ubuntu downloaded on it.
I tried booting up my system the other night and upon booting up I received the following error:
GRUB error: unknown filesystem.
grub rescue>
Can someone help me walk through the steps to fix this error so that I can use my computer again? Being that I so new to using Ubuntu I would greatly appreciate step by step (detailed) instructions.
