+--- Thread: Ventoy not booting .img files (/showthread.php?tid=2275)
Ventoy not booting .img files - Reedemer0fSouls - 12-12-2022
I make partition images in Ubuntu KK. If I save these images as .iso, Ventoy boots them just fine, however, if I save them as .img, Ventoy refuses to boot them. What am I doing wrong? I though Ventoy was supposed to boot .img files, was it not?

There is a standard specification for bootable ISO files, but not for .img files.
Different .img files have different format/layout, so Ventoy can boot normal .ISO files, but Ventoy can only boot some .img files, not all.
Ventoy need to test and adapt for each type of .img files.

I have tried saving bootable USB's as .img files using both dd and "Gnome Disk" (they produce the same result) by they don't boot. I have tried both the bootable partition and the whole device eg. /dev/sda1 and /dev/sda.
Changing the file extension to .iso doesn't fix the issue. Is there a recommended way of creating an ISO variant?
