sorry - I am in a hurry and dont have time for long explanations.
Have a look at my site http://sanbarrow.com/p2v2008r2.html
it has a sections "patching - the easy variant"
That applies to win7, 32 and 64 and 2k8r2
Use a recovery CD if the builtin recovery mode can not be launched.
Also make sure your vmx still have the lines
scsi0.present = "TRUE"
scsi0.virtualDev = "lsisas1068"
