Ventoy
Ventoy is installed to a USB disk.
After installation OS ISO's can be copy/pasted, dragged/dropped to the USB.
No further setup is required, unless adding persistence.
MS Windows installer disks can be be added.
Linux OS can be added.
FreeBSD, etc, etc can be added.
90%+ distros in distrowatch.com are supported.
550+ ISO files are tested.
There is Windows and Linux versions.
It is simpler to use than Etcher.

(sounds good but I prefer mkusb for it's hackability).
YUMI (The subject of the "Duplicated" Question)
YUMI has many loyal users.
It appears that YUMI is still well supported and kept up to date.
Have just tested the latest version YUMI-UEFI-0.0.2.7.
Preformatted the USB to NTFS, started YUMI and installed Windows-1909 installation ISO.
Then installed Ubuntu 20.04.1. (I think Windows should be installed first).
Both items installed and ran without problem. The NTFS USB worked in UEFI mode.
No workaround was required as shown in a previous answer to the duplicated question.
YUMI still lags Ventoy as Persistence is limited to 4GB Max. Also YUMI still needs to be run each time a new ISO is added.
