Today, My Windows XP did not boot as it displayed that WIn/System/Bit32 file is missing. I used theWIndows original edition and tried to boot. It booted but when I selected the Repair Console, it went through the programme and asked which program u want to repair "1.C:\Windows_. I typed 1 in the blank space and thereafter it asked for the particular program which I want to repair viz., chkdsk, bootsys (around 40 topics.) What should I do to repair my already installed WIndows XP?
