To create a recovery USB drive
Prerequisite: Ensure that the drive has a minimum of 1 GB of space.
- Format the USB drive using the FAT32 format.
- In the root directory on the drive, create a folder named EFI.
- In the EFI directory, create a subfolder named Boot.
- Access a client computer that has Symantec Endpoint Encryption Drive Encryption installed.
- Copy the following files from the client computer to the USB drive x:EFI/Boot directory, where ‘x’ is the drive letter:
C:\Program Files\Symantec\Endpoint Encryption Clients\Drive Encryption\
The USB drive is now a bootable UEFI drive.
To use a recovery USB drive
- On the non-booting client computer with the Opal v2-compliant drive, insert the USB recovery drive.
- Access the system’s Boot Options menu. Usually you can do this by pressing F9, F10, or F12 immediately after powering up Windows, but consult the user guide of your PC for more details.
- Select the USB drive (or, on some systems, select the \EFI\Boot\bootx64.efi file on the USB drive) from the Boot Options menu to boot from the recovery USB drive.
- At the preboot login screen, authenticate.
- After successfully authenticating, if the encryption record is still intact, you have the option either to decrypt without booting or boot directly into Windows.
- Press ‘D’ to decrypt the drive.
