Uefi 64 bit can only boot on 64 bit bios architecture. Uefi 32 bit can only boot on 32 bit bios hardware. The last time I had an issue booting rescue media in UEFI mode was on an Acer laptop which would not allow me to do so if Secure Boot was enabled.Īlso, uefi booting is specific to the architecture at build. Scott, all recent Acronis USB rescue media can boot in either UEFI or Legacy modes but whether this does so on your computer can depend on how the BIOS is implemented. Or in rescue media, use add new disk feature to initialize the destination disk first. In windows, delete the volume and then initialize correctly first. likely, you either need to format the destination disk and make sure it's initialized as the same as the source image (MBR or GPT), or the destination disk already has windows on it and should be formatted anyway so an existing OS (which also could be locked by fast start hibernation) is not present. Unlock the disk by doing a full shutdown so windows does not using a locked hibernation file and fastboot.

Fastboot on windows 8, 8.1, 10 locks a drive with a protected hibernation file that windows will recognize on the source disk and winpe or WinRE rescue media is windows and will see it too. You need to boot full Windows and do a full shutdown before anything. Really hard to provide a random "guess" to answer your question, which is the best you'll get without some information from your end.Īssuming a clone or a full disk restore is being tried.ġ. Andry, when are you seeing this? Are you using rescue media or is this from windows? Are you cloning or restoring a backup? If a backup restore, is it an entire disk or files/folders? If files, are you attempting to restore to the original location with existing permissions?
