Asking for help on my FIRST post... the epitome of lame. Sorry...
It's unlikely I'll resolve this one flying solo.
I pulled my Win XP SP2 drive that was working perfectly on an HP Pavilion Pentium 4 HT 2.80GHz PC w/4MB RAM; as I wanted to attempt running Windows 7 Pro on it. The motherboard is an ASUS Tek. I knew this would be a real stretch to get it going without it being constantly active from the system demand alone, but I wanted to give it a go. I concluded if it didn't pan out, I'd fall back to the Win XP drive and all would be good.
That didn't happen.
From the point where I unplugged the Windows 7 Pro drive and plugged in the Windows XP drive, that's where it REALLY went downhill. The immediate error upon failure to boot was: "NTLDR is missing". After making a boot CD-R from a backup image I had of an NT Loader image file, the next error I received was that the 'hal.dll' file was either missing or corrupt from the root\system32\ directory.
This is currently where I stand since I can see where this is headed. I'm speculating this may be the result of a flashed BIOS when I installed Windows 7 Pro on the other hard disk; however, I do NOT know this for certain. The current version of the BIOS is from American Megatrends v3.14 09/04/2003. I do not know what the date and version was before checking it today.
Is there anyone that may have some insight to this issue? I have a Windows XP, and Windows XP Pro installation disk if I should need it to copy files; but I CANNOT OVERWRITE this drive. I simply don't see files becoming corrupted or missing on a perfectly functioning hard disk and OS, so something else is obviously at play here. The only thing I could think of was a change to the BIOS during the Windows 7 Pro install on the other drive.
