I have a computer that has a fatal error and being able to run Windows Recovery Environment on the machine without requiring a full disk decryption would be the best solution at this point, not only for this laptop but for future cases similar to this. I have integrated (myself) the article here:

with the article here:

but when I boot into Windows RE the necessary tools for PGP are nowhere to be found. When I go straight from the symantec document Windows PE boots and does have the proper tools to access the encrypted drive, but as far as I know windows pe does not include any of the recovery tools in Windows RE.
