My current rescue media boots from CD, because I created it on my old PC which was running Windows 7, and which did not support booting from USB media.Ģ. The fixes attempted by the Fix Boot Problems wizard depend on how the Rescue Media itself was booted, so if you boot your Rescue Media in BIOS mode and try to have it repair a GPT disk set up for UEFI booting, it won't perform the correct fixes.Īs it happens, I would like to create new rescue media, for two reasons:ġ. And it's also not entirely accurate that it doesn't matter to Reflect how you boot to it. It is possible to create a Rescue Media flash drive that is only bootable on Legacy BIOS systems, although it is also possible to create BIOS+UEFI Rescue Media. The Reflect boot option is just an entry that points to a WIM file, so rebuilding it after this conversion is unnecessary.Īs for USB flash drives, they are not necessarily agnostic. The reason it doesn't matter there is because the actual boot portion in that scenario was already handled by Windows Boot Manager, which presented the boot menu in the first place. Nothing will change by recreating the Reflect boot menu option after switching from MBR to GPT and BIOS to UEFI. it does not matter to Macrium how you boot to it to do a backup or recovery from the rescue media.

Bootable rescue media on USB device is agnostic to the boot method and should boot fine via EFI OR MBR to the PC. One more thing, if you installed MR to the boot menu you should recreate your rescue media and update it.
