Restore Win 10 on BIOS/MBR to UEFI/GPT
Hello,
I have an interesting problem I need help with. I have a good Acronis TI2018 backup of a Win10 system that booted on BIOS/MBR. I now need to restore the same OS to a new system that only supports UEFI.
I setup the new drive at GPT but how do I create a UEFI boot partition and restore the OS?
Thank you!

Success!
I actually found two methods to solve this problem.
1) I manually re-initialized the drive as GPT then installed a temporary version of Windows 10 using the Microsoft media creation tool. This new OS was booted UEFI. I then booted a TI2018 Linux version from CD and it restored the original Windows 10. Acronis automatically restored the MBR based OS to UEFI.
2) Microsoft has a tool called mbr2gpt. It allows you to convert an MBR drive to GPT with data in place. Supposedly you can do it live from Win10 OS, but I preferred to do it using a Windows PE boot USB drive.

Always glad to hear of success regardless of the method to achieve it. Thanks for your feedback.

The above comment by @jgkurz is the most helpful tip I've read on this topic: use mbr2gpt.
I tried several times to convert my laptop from MBR to GPT using TI2020 (both Linux and WinPE versions) from a .tibx backup to no avail.
Then I restored my drive as MBR and used the mbr2gpt tool, changed my BIOS to UEFI only, and it booted on the first try.
