1. Turn on IDE emulation in the BIOS (if it does that.)
2. Change the AHCI mode (see google!) if you can.
3. Use the old ways with the floppy disk and driver.
4. Type HOW TO INSTALL XP TO A SATA HARD DRIVE on a search engine.
I have Windows Vista RC2 installed on my new Gateway laptop and I'm trying to install Windows XP on it. However, when I insert the CD and open the setup it says that I cannot install an older version of Windows over Windows Vista. When I boot from the Windows XP install disc, it says that It cannot locate my hard drive. My hard drive is a Western Digital WD1200BEVS. I don't know what to do. Have any ideas?
