Dear Parallels, I cannot start my Windows Vista Business Ultimate virtual machine. It keep giving me following error: ======= Parallels(R) 3.0 build 5608 (c) 2005-2008 Parallels..... 640 KB Base Memory 1048576 KB Extended Memory Boot from hard drive.... A disk read error occurred Press Ctrl+Alt+Del to restart ======= I am using MacBook Pro, the OS is Leopard (OSX 10.5.4), Guest OS is Windows Vista Business Ultimate. I have tried to use the parallels explorer to mount the hdd file but it gives me following message: ==== Parallels Explorer is unable to open file system volumne. The file system is not supported or contains errors. Start your virtual machine and check the disk for file system errors. ==== I am not using boot camp, I directly installed the virtual machine from the installation disk using Parallels. What should I do now? Thx!
