UEFI and USB boot

Thread needs solution

This is not urgent.  I want to head off any problems if I need to restore the image backup.  
I have created a USB boot device for Acronis.  With a previous not to be named backup product
I had an extremely difficult time rebooting back into Windows 10 after restoring a mirror image
due to my solid state UEFI drive.  Changing the boot device order required accessing the BIOS menu
and reverting to Legacy boot options to allow a device other than internal hard drive to boot.  
What is the procedure for Acronis?  I would be more comfortable if I had a description of the
procedure and known possible issues ahead of time.  I haven't found anything in the knowledgebase.

Hi eastwest

The limitation you're referring to is going to be similar to all offline recovery media, as it is dependent upon how your bios is configured.  Before you run into a situation where you need to recovery, you should test your recovery media now and make sure that 1) it boots up, 2) start a "mock" recovery and make sure you can navigate to the backup file and 3) during the mock recovery, make sure it sees your internal hard drive so that you know you'll be able to restore down the road.  You don't actually have to complete the recovery, but if you have a spare/extra hard drive, you could pull the original and restore the image to the extra hard drive instead and test booting with it to make sure all is well withotu risking your original hard drive and/or data. 

As far as the bios goes, some computers allow for both UEFI and/or Legacy boot at the same time, one or the other (but only 1 at a time), or only one type at all.  Acronis can boot both Legacy and/or UEFI mode and works on 32 bit and 64bit machines.  Getting your bios configured though may take some playing around if it doesn't boot right away.  Often times, you may need to disable secure boot and even if the system is UEFI by default, if there is an option to turn on CSM/legacy mode, that may also be required to boot to 3rd party bootloaders.

Take a look at this thread with screenshots of a Dell 5510 and the different bios options that can be configured and how the changes impact the type of bootloader options you can see when using yoru system one time boot menu or boot overrided menu.  Of course, each system bios is different, but hopefully it will give you an idea of what to look for on your own system.   When doing a recovery, the key is to make sure that you boot the recovery media in teh same manner as your OS was installed (if legacy, boot in legacy mode and if UEFI, boot in UEFI mode).  This is because how you boot the media, will determine how Acronis formatst the drive - MBR or GPT/UEFI.  You can usually go from an MBR to GPT (if your system is capable of booting UEFI), but you can never go from UEFI to MBR.
