I am currently receiving the same warning despite having officially installed Ventoy with the Linux shell script. The only difference between this installation and the previous ones is that this time I used the parameter to reserve disk space. Is this expected?

So am I since I finished setting up Windows 10 in a VHD (cf. forums.ventoy.net/showthread.php?pid=1503#pid1503).

Hi there.

Necessary conditions for Ventoy to work normally are (as stated at reboot.pro /topic/22277-ventoy-open-source-usb-boot-utility-for-both-bios-and-uefi/page-12#entry216140 and also at forums.ventoy.net/showthread.php?pid=1742#pid1742):

1. There must be partition 1 and partition 2
2. ISO/WIM/VHD/IMG/EFI files must in partition1
3. Partition1's filesystem must FAT/exFAT/NTFS/UFS/XFS/Ext234
4. Partition1's cluster size must >= 2048
5. Partition2 must in FAT file system and hold all the Ventoy's directories and files as installed with Ventoy2Disk

So, I took the time to thoroughly check my setup (see previous post) and confirmed that it abides all of them; I don't understand then why I'm getting the warning.



There are just two minor differences from a standard Ventoy installation: partition 2 has been doubled for future proofing and there's an extra ext4 partition at '/dev/sda3' -- an addition allowed by the official documentation.

You can create Part3 and Part4 with the reserved space and use them as you want.

Please enlighten me if you can -- or at least give me a hint on how to disable (or reduce) the ten second delay...

You can't disable the delay in 1.0.21, please wait 1.0.22.
In 1.0.22 only a "unofficial" word will be displayed in the main screen if the disk layout is not exactly the same with it created by Ventoy2Disk.

FYI, straightforward explanation from Ventoy's dev for both the OP error and the current "[Unofficial Ventoy]" message in boot menu:
