I just upgraded to Parallels 6 (6.0.11820.602974). After install I rebooted my mac, and then launched Parallels and my winxp VM. Right after the window transitions from "bios" to full screen and windows says "starting windows" I immediately get a BSOD. I took a screen snapshot (attached). This occurs whether booting normal or in safe mode. I didn't change any settings from my Parallels 5 install. I suspected possibly the new 64-bit support, but didn't see any preferences or vm settings for disabling that. Can anyone offer advice how to debug and fix?
