Okay, so I thought I would check out windows 7, made a new primary partition on my HD (which means I have 3 primary partitions, one used by vista x64, one by xp, and one set aside for windows 7 - plus an extended partition for storage), and tried to install from the boot dvd.
However, shortly after the 'Starting Windows' animation before installation starts i get a BSOD which reads:
STOP: c000021a {Fatal System Error}
The initial session process, or system process terminated unexpectedly with a status of 0x00000000 (0xc0000221 x001003a8).
The system has shut down.
I have tried my default BIOS settings (which overclock the processor) and default BIOS settings, both lead to the same error.
Pre-existing installations of Vista and XP both load fine, and I only re-installed Vista the other day with no problems.
Any ideas anyone??
