I started everything from the beginning with same result, where I have detected some issue via terminal - here the workflow:
uninstalling PGP in both OSs --> removal of bootcamp (incl Win7-64bit) --> reboot --> install bootcamp (without Win) --> install MacPGP --> install Win7-64bit on bootcamp --> install bootcamp drivers --> install WinPGP --> encrypting of HDD from MacPGP.
results: normal PGP-bootloader in Mac, PGP-bootloader in Win appears only for short time followed by black screen with cursor in the upper-left corner.
on this link I found some Terminal-comands to check situation of the disk (http://forum.pgp.com/t5/PGP-Whole-Disk-Encryption-for/WDE-Error-12293-Instrumenting-Disk-with-Boot-Camp/td-p/35242)
bootcamp is the 4th partition, so everything should be fine...
analysis via Mac-terminal was done after PGP-WDE from Mac - it finds a "suspicious MBR at sector 0" (see below) - how to fix this?
would be very happy to receive any helpfuld comments, kind regards, Stork
(booting into Mac is normal, decryption works also fine - this was tested too many times already...)
