system. It consists of tools to diagnose and troubleshoot issues that may occur before your computer boots to the operating
system. It enables you to diagnose hardware issues, repair your computer, back up your files, or restore your computer to its

multiple options for recovering Windows operating system on your Dell PC. For more information. see Dell Windows Backup
Media and Recovery Options.
BIOS recovery
The BIOS recovery is designed to fix the main BIOS, and cannot work if the boot is damaged. The BIOS recovery will not work
in the event of EC corruption, ME corruption, or a hardware related issue. The BIOS recovery image should be available on the
unencrypted partition on the drive for BIOS recovery feature.
Rollback BIOS feature
Two versions of the BIOS recovery image are saved on the hard drive:
● Current running BIOS (old)
● To-be-updated BIOS (new)
The old version is already stored on the hard drive. The BIOS adds new version to the hard drive, maintains the old version, and
deletes other existing versions. For example, A00 and A02 versions are already on the hard drive, A02 is the running BIOS. The
BIOS adds A04, maintains A02, and deletes A00. Having two BIOS version enables the Rollback BIOS feature.
