I had a friend help install windows, back then I was clueless about the whole deal with achi and ide. A while later, I had to switch hard drives just to run some tests, and the computer wouldnt but, even after putting the original back in.
Turns out BIOS had set itself to ACHI, not allowing windows to boot. Switching it to IDE made it work.
Now I bought an SSD, and its not quite detecting. Im also hearing ACHI is much faster than IDE, so I want to just spend time and switch over.
How would I go about reinstalling windows as ACHI? I have an installation disk and everything. I've already started backing up files to leave the boot disk empty and ready to roll.
