can not find bootable device!!!!!!
 

hello

well i am using dell inspiron 6000 with 2 partitions windows xp and the linux flavor kubuntu

the problem is i have blue screens (different error code each time) and each time i try to restart i get "cannot find bootable device press f1...." or i get repeatedly the word GRUB
and sometimes it doesnt give the blue screen errors but the laptop suddenly decides when i try to bootup the same problem "no bootable device"

i boot using the kubuntu live cd and reinstall the GRUB, and this fixed it and i could access both windows and linux, but the problem is that it is repeated almost everyday!

so do i need to reinstall windows or is there something else that i can do to fix this?!

HELP!

ps: i made no changes to the partitions, i only uninstalled oracle but that was a couple of weeks before this problem started to occur
