Hi there! A couple of days ago I bought Parallels (build 3188) to run Windows XP Professional on my 24" iMac with the 2,16Ghz Intel Core 2 Duo processor and 2GB of memory. I run it on Mac OSX 10.4.9 (8P2137). The problem is that I can't get a stable Windows environment! I followed the OS Installation Assistant and chose Windows Express (recommended). I proceeded to installing Windows XP Professional from an original CD and every thime the installation freezes, spontaniously reboots or simply gets in a loop. I tried it 6 times and the last time I finally managed to get a working Win XP Professional environment, despite the 2x reboot while setting up... Now, my Windows environment has also rebooted 2 times, the USB is not working (inside Windows there are no drivers installed for the USB controller and I can't get any installed either). I tried installing Xp Home Edition, but with the same results. I also tried installing from an ISO file and I tried another Xp Professional disc. After two evenings of installing Windows and pulling my hair out, I gave up... Can anybody help me with this?
