Thread: Ubuntu 11.10 wont load after upgrade from 11.04 and fresh reinstall
hi all,
have problem here, hope can me solve.
had running installation of ubuntu 11.04, tried update usb 11.04, apparently update went fine not able log in. mounted filesystem live cd, backed up, , did fresh install of 11.10 overwriting ubuntu partition.
after grub got broken, got reinstall using live cd again (grub ok, because can boot again windows in other partition).
when try boot ubuntu 11.10. kernel panic stating:
cannot open root device sda4 or unknown-block(0,0)
please append correct root= boot option
sda4 ubuntu partition, have swab in sda3 , windows uses sda1 , sda2
have run boot info script , here results, im not aware of wrong.
