Gratitude

Tried the ventoy app and it loads several ISOs.

Thank you for the great and comfortable app, at least: -) UEFI and legacy boot features-independent: loads in both cases; -) many ISOs on one drive; -) easy and fastest ISOs update/delete/add; -) easy and fastest ventoy app update, as I understood, w/o ISO files loss; -) Memdisk technique, where you can use it in compatibility cases and also to load your 5 GB ISO into PC RAM, and later proceed with fastest possible speed of PC: no any permanent storage media access in further load/install: all as fast as your manual actions and CPU+RAM bunch speed. Just amazing idea! Very old (15-20 years) RAM disk technique (where file folders can be loaded and managed in RAM), and that Memdisk came from alien's worlds also :)

I even still do not opened docs page of it (except Memdisk feature) to learn more abilities, including permanent configs.

Remember Dendy tv-box, remember cartridges for it? Ventoy is like that: 150 in 1: 150 ISOs - 1 ventoy-driven media

Glad to interact with it! Thank you so much for ideas and realisations! <3 <3 <3 <3 <3

$ pacman -Qi ventoy
Name            : ventoy
Version         : 1.0.23-1
...

Got update of PC package version, updated it on USB stick via sudo ventoy -u /dev/sda): saw the ventoy shows msg sort of "1.0.22 ---> 1.0.23", even did it twice: update 1.0.23 to the same 1.0.23.

Also switched to slightly another ISO: filename manjaro-kde-20.1.1-201001-linux58.iso sha1sum 4ff5f61dbcd211c352c6bc6d50c6aad78a2cac56 origin https://osdn.net/projects/manjaro/storage/kde/20.1.1/

Just the same error as was before:

error: device did not show up after 30 seconds...
Falling back to interactive prompt

sh: can't access tty; job control turned off

So "direct load" works fine until the desktop of OS, Memdisk mode outputs the error text.

[ventoy]

Memdisk mode is only for the ISO files which load everything into memory when boot and which do not need to mount the ISO after startup.

So not every ISO file can be booted in Memdisk mode.

Manjaro Linux ISO can't be booted in Memdisk mode, because it need to mount the ISO file after boot.

Got it. Thank you!
