I've been trying to create a 'multiboot' USB to install Windows 10 and 7 both from the same USB drive and I could not find any reliable solution yet, Is there a way to create such USB drive that can boot on older and newer systems alike?
What I have already tried:
Ventoy - Sometimes on older hardware, installation gets stuck with a black screen and a blinking cursor.
Easy2boot - Very slow and gets stuck on windows logo very often.
Yumi - Apparently isn't compatible with UEFI
WinsetupfromUSB - same as E2B, slow and gets stuck very often.
