Cannot Find Primary HardDrive

[brisal73]

I have two hard drives a C: (160g WinXp) and E80g Music etc...) drive. I am getting the NTDLR is missing error on a black screen. When I go into Windows Setup it does not recognize my primary C: drive (which has winxp installed). I see the E: drive, but that's it.

Does anyone have any ideas how to get my C: drive up and running? Any help would be appreciated

you may need to use another machine and see if disc manager can set it active
if OS see's it at all
or use the xp disc and try a command window that may let you see the first partition.
there are a few bootable free disc utilitys out there if you can get someone to burn and try repair and copy the files needed
seems files are there,something has deactivated the c drive
