Hi. I reformatted my laptop yesterday, it had two partitions. C: was Vista and D: was XP. I just formatted and installed on C:. I was installing everything and it was all going well. My laptop had SATA IDE compatibility mode, so XP works fine. I wanted to install the SATA drivers for better performance. I was following a guide, and all was going smoothly, but, I had a different version of driver then the guide, and I accidently chose the wrong device in the ".inf" file. Now my C:\ XP won't boot. I've tried Sata compatibility and enhanced mode. Nothing. Can I change it back at all? I just get a BSOD then it restarts. I've got the other XP so I can change files ect.
