Unknown file system on a flash drive?

Question

Solid State Drives

Good day to all! I have a half-dead screw on my computer, so from time to time I have to walk through it Victoria HDD and HDD Regenerator. To do this, I use a bootable USB flash drive with this image . But recently, when booting from a USB flash drive, such a misfortune has appeared: Why

does it occur only when I need to access DOS programs (for this, just a USB flash drive is set in boot device priority), Windows from the same image (for this, in boot device priority exposes UEFI: flash drive brand) can be loaded safely. Tried to format the flash drive, overwrite the image. Everything worked only once, when Sim boot was run on a flash drive before recording. But even that doesn't help now. Can you tell me what's wrong and how to fix it?!??

Answer 1

As a result, I found a solution to the problem in the comments on the Sagittarius website. It is necessary after recording the image to copy the bootmgr file from the SSTR folder to the root of the flash drive with a replacement and voila everything will work as before

Answer 2

There is an assumption that the partition table is in GPT format, which dos does not understand.
