|Still am fighting to get Parallels 3.0 (build 4124 and 4128) to work on my Macbook Pro with my Windows Vista Ultimate edition which is running fine under Bootcamp along with VMware fusion beta 4. Today, I upgraded from Parallels build 4124, which used to cause blue screen of death to Parallels 4128; and the same problem(s) continues again with new upgraded release; not sure how to get Parallels to work with Bootcamp Vista.
I get the new blue screen of death now. So, I booted back Vista under parallels using Safeboot with network; and uninstalled Parallel Tools. But sub-sequent boots caused the Vista not able to boot under Parallels as well as VMware; as it is keep complaining about the missing c:\windows\system32\hal.dll file at the boot screen itself.
So, I did a direct boot to Vista; and that seemed to work, which saved my life not to reinstall or repair the Vista OS…and this time I didn’t dare to boot back with Parallels ; as every time I boot; I get into new set of problems. VMware Fusion seemed to be working fine, even though I noticed that it tries to register the OS again…but at-least it looks like stable on my environment; and I think I will get settled with Fusion for now; as it has much better performance than Parallels along with it also supports Readyboost. I will wait for the upgraded version of Parallels to try later and also wait for Fusion to support Unity for Vista editions.
