Future of Acronis with UEFI on Win 10
I had a years old computer crash but had extensive backups of TruImage version 2014. I replaced the aging box with a 2019 laptop and readied the boot USB, in order to mount the image as a virtual drive on the new Win 10 Home laptop. No go. UEFI and Secure Boot prohibited it. Hours later of research appeared that my particular new laptop would not allow Legacy boot. Which begs the question: Why back up for years successfully if Windows will not let you restore? It seems the worse of all worlds. I was able to recover files by restoring to another older machine (20 hours), then copying a few over at a time. Not pleasant. What am I missing? How can one be absolutely certain that files can be restored when the time comes on a Win 10 machine, and what technologies are employed to get around the Secure Boot? Are we stuck with "Win 7 image" - the red headed poor stepchild of Microsoft's backup tools? Any help appreciated. Regards, Michael Clifford

As Steve said, you don't need to boot your recovery USB to access your backup data. Just use open the .tib in Windows' File Explorer and copy the files you need to recover.
There is a big difference between recovering a dead system - recreating your old Win 7 system - and recovering files from that old system. You have the tolls to do either task, but they are different tools.
I assume you really don't want to recover your old Win 7 system, but suppose you did want. Then you would have to be concerned about Secure Boot, UEFI vs legacy boot, GPT vs MBR, etc. The simplest way to deal with Secure Boot is to disable it if you know you are going to boot from a safe source. (You can always re-enable it afterwards.) And if your old system was a legacy BIOS system you will have to make sure your new computer can boot in legacy mode. When you boot your from your recovery medium you would need to use the non-UEFI boot option. (If your recovery medium was created many years ago, that may be the only option. But if it's that old it may not have drivers for your newer hardware. You may need to create a new recovery USB.) Or you could boot in UEFI mode and build your recovered system as a UEFI / GPT system. (I haven't done this so don't know what extra work may be required.)
The bottom line is that Acronis provides the tools to do this. But if you already have a reunning Win 10 replacement for your Win 7 system, those tools don't come into play. Just do what Steve said.

Hi I can only reinforce previous posts.
It depends on the following:
Is CSM (compatibility mode) enabled in BIOS, which allows either UEFI or legacy boot devices (Windows, USB sticks etc, Acronis survival kit).
About CSM Legacy and UEFI:
Which is the OS that you want to recover. Only 8.1 onwards do seriously support GPT, UEFI and secureboot. It was introed with 8.0 but very poorly.
If you want to full recover Windows 7 however you need to boot legacy, you cannot restore it as GPT as it won't boot. It cannot handle GPT for boot devices.
If you have a backup that contains MBR scheme you can boot this in legacy mode only or with UEFI and CSM enabled results in legacy too.
Check your GPU compatibility with UEFI boot:
If you have Windows 10 and still use MBR, your graphics cards support must UEFI GOP (Check with GPU-Z) you can and should convert your boot scheme from legacy to UEFI and enabling secure boot.
Finding out your current mode:
You can check the settings in msinfo32. BIOS mode is either legacy or UEFI. If Legay, Secure Boot will show unsupported.
Finding out your scheme quickly:
Windows Key+X open Powershell with Admin rights
get-disk
From the output check your Windows boot disk if it is GPT or MBR.
Conversion methods:
You can also convert Windows 10 Backup from MBR to GPT with a restore, however it is easier than that.
Boot from Windows 10 USB stick created with the latest Media Creation tool or ISO with >latest< Rufus (Rufus also allows an ISO download from MS servers.
Make sure to boot it up as UEFI (eventually use BIOS boot menu selection, your stick may appear as "Devicename" and "UEFI: Devicename"
When seeing the first Win10 setup screen issue
Shift + F10
issue
mbr2gpt /validate /disk:0 (assuming that your Win10 is on disk 0, it should be anyway connected on the first SATA port (0) aswell.
if this throws an OK.
mbr2gpt /convert /disk:0 this will convert your Windows from MBR to GPT which is regularly needed on modern systems that were upgraded from Win7 or 8.x and UEFI was not enabled ofc.
I never had any issues with this, except it might throw that something went wrong with Windows Recovery since 1903. However you cannot simply make this change undone, a tool that can is Partition Wizard Free (watch out closely what you install and bloatware)
