So I recently acquired a used Dell Optiplex GX280, only problem was the harddrive, easy fix, grabbed one of my IDEs and installed XP on it (deleting the current Windows ME partition). Then crap, forgot to grab the drivers! So, at school, got my drivers on a flashdrive, got home, hooked up the HD, and now I'm getting an error on start-up.
It's telling me that the Primary Hard Disk Drive 1 cannot be found, then it goes on to say that the Secondary Hard Disk Drive 1 can't be found, but yet it's registering in the BIOS. I hit F1 to continue as it says, but it then proceeds to tell me that NTLDR is missing.
I'm lost as to what to do now, the XP installation was sucessful, and it was running last night (with no internet

). Keep in mind this computer isn't going to be our primary, this is going to be one in my room, not really used for gaming but more or less the random internet browsing I'd do.
Thanks!
