I upgraded from Karmic Koala to Lucid Lynx beta, was working fine for a while (was even rebooting). But, after some time, it is not booting and i cant find a solution.
I have tried installing the grub again, doesn't help.

Well, the problem is all my settings, bookmarks and passwords are blocked in that partition. I cant find where the Chrome stores bookmarks in Ubuntu.

Can you help me either getting my system rebooted or getting the bookmarks ?

p.s. I am currently on liveusb.

Edit: The grub menu comes, and it runs (as it should for 6-7 secs) and then a blank screen comes and after some time, there is an error some what like below

Busybox 1.3
Job control turned off
Cannot access tty
/bin/sh ..

grub.cfg file at pastebin

Edit 2: The same thing happens when i boot with recovery option. (something like below)

[2.176345] device-mapper: dm-raid45: initialized v0.259
[6.873452] scsi 5:0:0:0 Direct access

after waiting for some time, the following shows

BusyBox v1.13.3 built0in shell(ash)
Enter help for a list of built-in commands
/bin/sh: cant access tty: job control turned off (in initramfs)

Also, earlier when i was able to boot into Lucid, I used to edit the boot option like below :

insmod ext2
set root=(hd0,5)
linux   /boot/vmlinuz-2.6.32-16-generic root=/dev/sda5 ro  
initrd  /boot/initrd.img-2.6.32-16-generic

Now, the above runs for 2-3 seconds,

recovery required
recovery done
mounted filesystem

after that its a complete black screen (for like atleast 3-4 mins)

when you get this error, you're attempting to boot into the standard kernel, yes? does the same thing happen if you choose the recovery kernel? – quack quixote Mar 24 '10 at 0:55
