This issue has been solved. See solution.

I have a MacBook Pro, 10.6.8 SnowLion. I have lost the PGP Desktop Enterprise (10.0.0, Build 2732, PGP SDK 4.0.0) pasphrase. I have made a Time Machine back up and would like to format my HD, reinstall 10.6.8 and recover with Time Machine. How can I boot to the OSX disk to reformat my HD? Will the boot guard prevent this? Thanks.

You will need to access the drive from another OS in order to format it, or get a bootable disk to nuke the hard drive.

Thanks for the quick response. Just to be clear, I can insert my original OS DVD, hold down the C key on start up and this will bypass the boot guard allowing me to install the OS?

Yes that is correct that_guy. When booting the CD, you shouldn't even be prompted for the PGP passphrase at bootguard. Since we are not booting the hard disk, so the EFI file where bootguard is stored should not even be getting accessed at that point.
