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.
