I just installed Windows 7 Ultimate 64 bit. Did the usual Disk Shrink in disk Management to prepare for dual OS on a 128 GB SSD drive. I rebooted and installed Windows XP Pro 64 bit. Everything went fine other than when the system restarts and I expect to see the option of selecting what OS I want to boot from.....it just continues on and boots up XP. This is a brand new build Gigabyte MB, i5 CPU, 8 GB Kingston DDR3. I have checked everything in the bios, and don't see anything out of the ordinary. Have never ran into this before, any ideas ? Btw, I have 2 other drives ready to go but the are not plugged in. Just the Kingston SSD.
