Hi all,
I have a problem here, hope you can help me solve.
I had a running installation of Ubuntu 11.04, then i tried to update from USB to 11.04, apparently the update went fine but then i was not able to log in. So i mounted the filesystem with my live cd, backed up, and did a fresh install of 11.10 overwriting ubuntu partition.
After that grub got broken, i got to reinstall it using live cd again (grub is ok, because i can boot again into windows in other partition).
Now when i try to boot Ubuntu 11.10. I get a kernel panic stating:
cannot open root device sda4 or unknown-block(0,0)
please append a correct root= boot option
sda4 is my ubuntu partition, i also have swab in sda3 and windows uses sda1 and sda2
i have run boot info script and here are the results, im not aware of what could be wrong.
Boot Info Script 0.60 from 17 May 2011
