Endpoint Encryption

Dear All,

I need your help for PGP recovery.

First, I installed WinXP and Ubuntu 12.04 LTS Daul Boot system on my Thinkpad T410, and there are two drives, C and D, on Windows system. Next I installed PGP on Windows and encrypted C drive only. When I rebooted my computer there is a PGP Initial UI to input password, and then I could select Ubuntu or Windows XP.

When I upgraded Ubuntu's kernels, I have to append menu entry for Windows XP in grub.cfg file, for instance:

menuentry "Microsoft Windows XP For IBM" --class windows {
    insmod part_msdos
    insmod ntfs
  search -s -f /ntldr
  ntldr /ntldr
}

so that I could select windows.

But yesterday after I upgraded Ubuntu and rebooted the system, I could not see the PGP Initial UI so that I could not access Windows now. I think the reason may be that the new upgrade updated MBR, then destroyed the PGP Initial UI. So could I recover  the PGP Initial UI? Should I use PGP WDE recovery disk image? How could I check my PGP version?

Thanks a lot.

I have the similar environment as the blog: http://blog.securism.com/2009/01/recovering-a-pgp-whole-disk-encrypted-drive/

But there are some differences:

1. I only encryped C drive in Windows, and my D drive could be mounted in Ubuntu

2. I could boot Ubuntu system

The output of "fdisk -l" on my Ubuntu:

Some more questions:

1. My colleague told me the version of PGP is 10.2, but should I confirm it further since there are so many subversions? see: http://www.symantec.com/business/support/index?page=content&id=TECH176201

2. Could I create a bootable USB drive using this iso image instead of CD ?
