Support for .img files are broken in 1.0.22 ???

[mat-industries]

Which IMG did you test?
Please refer https://www.ventoy.net/en/doc_news.html for supported IMG files.

I have tried self made img files. Created a vhd, installed different operating systems, mostly dos. Then i convert the vhd to img with qemu-img.
All images seams to be fine, but there wont boot with ventoy.
First i will try now one of your tested img files, but for future there will be great to know how to build img files that are bootable. :-)
Is there maybe a howto ?
