Problem on upgrading from 10.04 to 12.04

[manosonem]

Hi,

yesterday i decided to upgrade from 10.04 (32-bit) to 12.04 (32-bit) but after rebooting i get the following error(s):

** (plymouthd:317) : WARNING **: Command line 'dbus-launch --autolunch=ca673ea319228ac3ae5ce7964e2eab4a --binary-syntax --close-stderr' exited with non-zero exit status 1: Autolunch error: X11 initialization failed.\n udevd[341]: specified group 'colord' unknown

[ 5.831191] sd 4:0:0:0 [sdc] Assuming drive cache: write through
[ 5.831191] sd 4:0:0:0 [sdc] Assuming drive cache: write through
[ 5.831191] sd 4:0:0:0 [sdc] Assuming drive cache: write through

And in the next 3 lines there is a message that i can not read well because of the encoding(greek) but it says something about pressing "S" or "M" but if i press any of these buttons, nothing changes.

This message appears after the post screen and it does not reach to enter the grub.

Hi,

GRUB has already booted, but it's menu is set to be hidden with no timeout.

Do you have any pen drive or external hard disk plugged in?

It seems there's a problem with sdc, which means the third hard disk (it could be a pen drive too).

S is to skip and M to manually repair, this usually appears when you face a disk problem.

You can try booting from a live cd and doing fsck on all the partitions, (/dev/sdc1, /dev/sdc2, etc) also you can edit the grub.cfg or re-build it with this live cd to have a timeout.

I hope this helps.
