I have a new 27" iMac with the i5 processor, Snow Leopard, and 8GB of Ram. Using the secondary display trick, I was able to successfully install Windows 7 (64 bit) with Bootcamp and it is working great. But I also have Parallels Desktop 5 (latest version) and am having troubles with it running Windows 7 from my Bootcamp partition. I was able to get the virtual machine installed and Windows 7 will boot. However, it takes a LONG time to start the virtual machine and hard drive access is VERY sluggish. To be clear, Parallels itself loads fast but once I start the Windows 7 virtual machine, it takes 5-10 minutes to loads. But even after it loads, any time I do something to access the HD, it is very slow. For example, if I try to play a game, it'll take a long time to load the game but once it gets loaded, it runs great. So I know it's not a memory, CPU, or GPU issue. I have 4 GB or Ram dedicated to the virtual machine. Now I thought I read something about Parallels having trouble with Windows 7 when using the Bootcamp partition - something about a HFS reading problem from a Bootcamp driving or something? My Mac is booting into the 32bit kernel of Snow Leopard and the Windows 7 installation is 64 bit? Would that be causing a problem? I also have Macfuse and Paragon NTFS installed on the Mac. Would those be causing a problem? Specifically, what do you think could be causing the very slow hard drive access in my virtual machine? I wasn't able to find a solution at the Parallels website. Thanks!
