[SOLVED] I made a Macrium Rescue disk on a pen drive but when I tried to boot from it there's an error ?

[JockyMacIntosh]

I have a GigaByte Aorus b550 pro ac board and a
AMD Ryzen 7 3700X CPU 8 Core 4.4GHz Boost CPU running Windows 11.
After installing my windows 11 and various programs, I installed Macrium reflect and made a backup image.
I then made a Macrium Rescue disk on a pen drive.
However when I rebooted from the rescue disk to test it, I got an error saying this type of disk is not supported.
Now, I am not sure, but I think the error said something about GPT not supported.
Can anyone advise ?

I use Macrium, but can't recall anyone having that issue.

You chose the USB flash drive from a boot menu using an F key??

Can you boot from that same flash drive on some other PC?

There are certain choices to be made when you make the rescue USB. Can you remake it using other choices? I think it would be properly formatted within Macrium during the process.

Can you make another rescue disk using a different flash drive?

Make a photo of error message and show here.

I am about to do so now. Last time it stopped the windows boot manager from booting and I had to do a reinstall. Here goes !

Just guessing here (since no photos) ...
Macrium rescue flash drive could be created for legacy boot.
If you have configured BIOS to allow only UEFI boot, then legacy boot sources can not be booted anymore.

Wow !! Thats a relief. It worked perfectly.
The last attempt must have been a faulty pen drive. I threw it out.
I used a new pen drive this time and all is well.
Thanks
