I was trying to eviscerate the autocfg.ini virus (or something like that) that kept hanging my reboots and infecting my zip drive. I did a bunch of attrib -r-s-h looking for hiddent files (1ogf.exe type things) and accidentally deleted the ntldr file. Can't re-install XP because I can't SEE my boot drive. Install won't work in normal or repair modes. diskpart doesn't see any partitions. If I try to install XP I get "unknown Disk" and if I try to delete that partition I get the BSOD. Everything was working fine hardware wise so that is not the problem, not is my ram or any of that. Please help.
