I recently had a "SMART event" on my c: drive. I could no longer boot because "windows/system32/config/system" was missing or damaged. since i have two hdds i thought maybe i could swap them, install xp on the new c: and access the old c: (now d:).
next problem - no space on hd for os partition. So, I reconnected the drives in the original order and tried to reinstall xp but found "no hard drives connected to system.
now some parts of boot system see the drives but other don't.
I added a second hd to an older system and had a hard time installing it but don't remember what the proceedure was.
Any help greatly appreciated.
