I can't run Parallels desktop on my mac os x computer even though it worked before. XP still works through bootcamp, but when I start parallels i get: "windows could not start because of a computer disk hardware configuration problem. Could not read from the selected boot disk. check boot path and disk hardware. Please check the windows documentation about hardware disk configuration and your hardware reference manuals for additional information." I followed what they have on the parallels support, which is to check the disk through disk utility on the mac side etc. Uninstall parallels etc. and then reboot. Did all of it and it installs fine, but I can't get xp to run.
