Thanks for the reply!
I didn't install GRUB, nor do I know what that is.
for bootrec/fixboot - i got the message
"The volume does not contain a recognized file system. Please make sure that all required file system drivers
are loaded and that the volume is not corrupted."
for bootrec/rebuildbcd - i got this
"Total identified Windows Installations:0
The operation completed sucessfully."
Still the same thing when I rebooted, I'm guessing I'll have to reformat now; if so is there any ways for me to backup what i had?
