Parallells 5 extremely slow

[gman901]

What's up with Parallels 5 and Windows 7? It seems to take forever to boot up into Win 7 compared to Parallels 3 booting to Windows XP. Also, I did the automatic installation and it gave me two shortcuts, "My Bootcamp" and "Windows 7". It took a long time to install, then it told me I would have to manually configure the rest of the way using the Windows 7 disk? I did not install the disk and let it finally finish. Now every time it boots up, I get a warning message that it cannot locate the primary hard drive to boot from, yet it finally boots up on its own. It seems very confusing and sluggish compared to older version of Parallels working with XP. Is there anything I can do to have a smoother boot up experience with Windows 7 and Parallels 5? Should I have gone with VMWare Fusion 3?
