i have installed ubuntu inside windows and then afterwords i installed fedora 16...all time during start up its show os selection by grub loader but after i did some partition on windows its shows error:unknown filesystem.enterting rescue mode..
My Ubuntu 10.10 system suddenly froze/crashed for no reason and I had to hard reboot my computer. Surprisingly it doesn't load anymore and stay stuck on a grub rescue prompt after an "unknown filesystem" message.
I had Windows 7 and Ubuntu 10.1 installed in my intel i3 4gig DDR Sony Vaio E-series laptop. Both operating system were working fine. Only problem that I used to have was the sound didn't use to play when I boot through Ubuntu. Due to that, I formatted the corresponding drive from Windows in which there was Ubuntu installed.
Hi All,
Ubuntu 12.04 will not boot on my laptop. I keep getting the following error.
error: unknown filesystem.
grub rescue>
I am able to run a live-cd. I have tried using boot-repair-disk.iso; however, it says something to the effect of the boot repair was successful and to restart the computer... I restart the computer, and I get the same error.
Please advise.

I did a dumb thing... I forgot that Ubuntu 10.04 (Lucid) switched to Grub2 which puts a ton of *.mod files (kernel modules) in /boot/grub. I thought they were soundtrack files put there erroneously and moved them. Needless to say, the next reboot was traumatic. I was presented with something I had no memory of ever seeing...
I have Win XP and Ubuntu 10.04 dual boot.
I was trying to uninstall Ubuntu. Instead I removed the partition and the result is:
error: unknown filesystem
grub rescue>
I tried to boot from a 10.04 and 10.10 Ubuntu CD and I get the same error message.
Please help.
Thanks
Hi,
I'm a pretty new Ubuntu user, and I can't figure out what to do from searching other threads.
Anyway, here's my situation:
I had Ubuntu 12.04 installed on a partition, and OSX 10.7 on another, and it worked great. Then after I installed 10.8, my Ubuntu partition no longer worked.
I have a netbook with a dualboot for Windows7 and Ubuntu..I accidentally deleted the partition for Ubuntu then after I restart my netbook it goes directly to the error: unknown filesystem grub rescue>.
Hi I recently had Ubuntu on a partition, but it didn't work out so I went on windows 8 partition and deleted that partition. However, now when I restart my computer it will not load anything and gives an error of
Error: unknown filesystem.
grub rescue>
I don't know what to do and I don't know how I can log back into windows or anything.
