problem in linux partition
yesterday i made shutdown to my pc.When I again booted then surprisingly mi got the grub error 17.so as usual I took my ubuntu live cd and tried to boot from it so that I could be able to fix grub(if there is some error)
but live cd failed to boot into os and gave some errors like that:Buffer [355.005069]I/O error on sda 8 logical block 0
[355.005069]ata3.00:exception emask 0*0 sact 0*0 serr 0*0 action..
and to it there were also some unusual lines
Also my xp is working fine.
I dont know what to do now??
