The new install of XP on a new drive without the other drive in place would be C and D as you partitoned it. Then when you added the old drive, the new XP should have reidentified your,old partitions.
I did similar but left the other drive in. My XP drive failed, the other drive had four FAT32 partitons.E,F,G.H. I then got the first drive replaced under warranty and reinstalled XP on it. The XP drive was then I and J. Yes, the boot drive was I . system worked fine, however it only had one XP on it.
Can you put a Win 98 boot floppy in and run del directory and delete the Windows directory on the second drive?? Not quite sure of the syntax may be deldir. If the original is in NTFS format then the Win 98 floppy won't work. Just download delpart and run it from a floppy and delete that partiton.
Probably many other ways that will follow.
Please point me in the right dirrection. I installed a new drive and loaded it with windows XP. I then installed my old drive (windows XP) into the other position with the hopes I could access it and move some data and applications over from it. No luck cannot access it. My new drive is partitioned C, and D, my old drive is C, D, E, F, and G. My CD is drive M.
My computer has 1.31 Ghz AMD Processor and 512megs of ram.
Your help is appreciated
