Ventoy s the best way today, in my opinion, to install - and test - LiveISOs, better than YUMI and Multisystem, that are the alternatives.
I installed my Manjaro Gnome with this software, and a pendrive, but, the KDE version do not work with it after the Manjaro Welcome that works, so it is not a copy failure - i think -
I am so in love with this software to install and test LiveISOs that I would like it to become the de facto standard for installing LiveISOs, and even imgs, and as Manjaro x86 and arm (pinetab) are my favorite distros, this check for compatibility for the liveISOs - only to advice if it works or not if it is a lot of work to fix if they do not work - would be great.
If Ventoy fails to boot an ISO there is always the imagewriter in our repositories.
I know in stable branch the ventoy package is at version 1.0.29-1, a bit behind of the latest release, but testing and unstable have 1.0.30-1 version. Anyway, for the AUR package we have @Yochanan as copackager, hence there should be no problem with it either.
Maybe you can share some logs. I can boot the Live Session of each latest Manjaro ISO i tested …
Windows users has to be paranoid - that comes with the territory - that said - antivirus uses a better-safe-than sorry approach when it comes to signatures - and since ventoy is a an application which writes data to the boot sector - and virus scanners have signatures from real malicious code which resembles - ventoy code - then false positives are bound to happen.
I admit I have not done a source review of ventoy since my first reviews but I believe those are false positive - or another possible option which is someone offering malicios downloads disguised as ventoy - for the time being - I have no problems with ventoy.
The install program Ventoy2Disk.exe has not been updated for some releases. It seems that it has been added to the whitelist of anti-virus software vendors. But Ventoy2Disk.exe is updated in this release, so there may be some false positives again.
Really confusing why this might be the case. There shouldn’t be any meaningful difference between gnome and kde isos in this respect. They are built with same toolchain, same kernel, same bootloader, same drivers and so on. Nothing that affects booting is different between those two.
Just tested the latest Manjaro ISOs (KDE and XFCE) with the latest Ventoy. Sure enough XFCE boots up with no problems while KDE gives me this error:
mount: /run/miso/sfs/rootfs: wrong fs type, bad option, bad superblock on /dev/loop3, missing codepage or helper program or other error.
ERROR: Failed to mount `/dev/loop3`
Falling back to interactive prompt
You can try to fix the problem manually, log out when you are finished
sh: can't access tty: job control turned off
something went wrong when you copied the KDE image to the USB stick
perhaps the download was already corrupted
perhaps the copy to the USB storage didn’t complete
before you yanked the stick out?
… just two of a couple more possibilities
