What we can do if a bootable PGP WDE drive fail to boot the OS correctly? Initially we can try to do a recovery operation using the OS bootable CD/DVD or restore to a previous known best configurations point. But think if those operations also fail to recover the OS boot process. Then the option is to reinstall the OS. But as the drive is encrypted, we can't simply reinstall the OS on the same drive. If we do it, it will cause a data lost. Therefore, we need to decrypt the drive and install the OS. Then again encrypt the drive.
We can do two things in such a scenario.
1. Remove the drive and connect it to another PGP installed machine as a slave drive and decrypt it via the PGP desktop.
2. Use the boot.iso to boot the machine and decrypt the drive using bootable cd.
In this post I will describe how to do it using the boot.iso or bootable PGP CD.
First you need to get the correct version of the boot image (boot.iso). It is important to have the same version of the Symantec PGP software to avoid any data lost.
Best way to find the boot.iso is to burn a CD image after initial PGP desktop installation. You can get the image file from these location according to the OS.
32-bit :- C:\Program Files\PGP Corporation\PGP Desktop\bootg.iso
64-bit :- C:\Program Files (x86)\PGP Corporation\PGP Desktop\bootg.iso
Or you can download it from the Symantec website.
Then boot from the CD drive. It will prompt the initial PGP login screen. Do not enter the user name and passphrase. If you can go to the "Advance panel" go to it and try to decrypt the drive. (But in my case I haven't got a advance panel.). But if not, press F4. It will direct you to the WDRT window. Get the WDRT from the server and type it. After submitting the WDRT boot disk (CD) will try to decrypt the encrypted drive. This process will take some time (very high). Don't stop it and make sure power supply is OK.
Keep in mind if something goes wrong, it will cause a data lost and you wan't be able to reverse the operation.
