Yesterday I got a problem which I posted here. Trying to solve it, I installed slitaz live CD to desktop. After that I tried to use boot other live CD's (Ubuntu, Tiny core) but they didn't boot. So I deleted the the slitaz partition through gparted(or something like that) and restarted. After that I am seeing this error message:`

GRUB Loading stage 1.5.
Starting cmain() ...

GRUB loading, please wait...
Error 22`

I have tried Backtrack live CD to live boot laptop but that doesn't work too.

Boot Backtrack or ubuntu live CD. Open terminal and run command "update grub" as root and then restart your laptop.
