How to check if a Veritas System Recovery Disk (SRD) is booted in UEFI or BIOS mode.

Problem

Solution

1. Boot from the recovery disk
2. Click on Analyze
3. Click on Open Command Shell Window
4. Type the following command: wpeutil UpdateBootInfo
5. Type the following command: reg query HKLM\System\CurrentControlSet\Control /v PEFirmwareType

If the command returns 0x1, the recovery disk is booted in BIOS mode. 0x2 represents UEFI mode. The below example shows a recovery disk booted in UEFI mode:

NOTE: If you create the SRD on a USB drive that is formatted as NTFS, the SRD will only detect BIOS. If you need to create a USB Veritas System Recovery Disk that needs to boot on both BIOS and UEFI (firmware) computers, then you must create the recovery disk on a FAT32 USB drive.
