"You need to format this drive before you can use it" error. HELP!!!
I tried booting my computer a few days ago (HP Pavillion a1730n w/Windows Vista), but got an error that said "BOOT FAILURE". I hit enter and it just says "err2 err3" and it just hangs there. So I tried using the windows vista repair disk, but it would find any operating system. While using the repair disk, I searched for the hard drive (C:\)I was trying to boot from and clicked on it. It said "You need to format this drive before you can use it". To try to fix this, I tried to run a disk check, but I got a message saying that windows cannot access the disk. How am I supposed to fix this without having to format the hard drive and start all over again?
