unable to find my all local disk partition?

[kmanish75]

i m using windows 7 and i m facing a very strange problem. I did some changes in my bios. actually i was trying to install windows xp from hard drive itself but nothing work so i switched it off.. then on next morning i run my computer and found that its not working and it was asking for repairing CD. And now when my windows is repaired it is not showing my all local disk. In My computer there is only one hard disk drive i.e drive C:\ (30gb) is visible. my hard capacity is 500gb but only C drive is visible. i don't know where my all drives are gone i.e D (100gb), E (100gb), F (100gb), G(135gb).they are not visible not even in disk management..Please help i don't want to loose my data.

sorry for my bad English.

Hi, Welcome to Seven forums.

First thing, why were you installing Win XP from your hard drive? And what changes did you do in BIOS?

You might have removed the drive letters. Follow this link and perform the steps. Change, add, or remove a drive letter - Microsoft Windows Help
