After rebooting a PGP Whole Disk Encrypted system and successfully entering the passphrase at the PGP BootGuard screen, the computer displays only a blinking cursor in the top left corner of the screen and Windows fails to load.
This issue can be caused by a recovery partition on the computer conflicting with PGP Whole Disk Encryption. Many hardware makers include a partition on the hard disk of the computer for recovering your system.
In most cases, this issue can be resolved by decrypting the disk using a recovery disk and then encrypting the disk using partition encryption. However, in some instances, the recovery partition included on the computer must be deleted before performing PGP Whole Disk Encryption.
Use the following steps to recover and re-encrypt the disk
Backups should always be on hand before performing this operation as this could lead to a loss of data. If backups have not been created you will need to make an image of your disk, and transfer that to a new drive. Use the drive with the image for all testing and troubleshooting so that the original remains intact.
Should the above steps fail you can try decrypting from the recovery CD itself using the following option. Again backups should be on hand. If you do not have a backup and one cannot be made an Image should be created and loaded onto another hard drive. You can then use these steps on the drive with the image while leaving the original disk intact for use by Technical Support.
|Note: Once a disk or any of its partitions have been encrypted, you cannot change the disks partitioning (for example, adding or removing a partition, or resizing an existing partition). Make sure the disk is partitioned the way you want it before protecting it with PGP Whole Disk Encryption.|
If the issue continues to exist after re-encrypting the disk by partition, try removing the recovery partition on the computer. For information on removing the recovery partition, check with the hardware maker of your system.
