What happened?

This concerns only the installation part of Ventoy. Using the Partition Configuration menu, Ventoy seems to be allocating the wrong amount of space.

Device info: Ubuntu 20.04, arch x86_64
Package: ventoy-1.0.91-linux.tar.gz
Installation file: VentoyGUI.x86_64

With my 128 GB Samsung USB drive, I requested 118 GB of reserved space at the end of the USB stick with the Ventoy2Disk GUI. I click Install. This should leave roughly 10 GB for the .iso partition. Instead, Ventoy only uses 1.6 GB for the Ventoy partition and leaves 127 GB as free space.

I tried preserving 110 GB and clicking Install but the amount of Free Space is 118 GB instead of 110 GB.

Finally, I tried with 32 GB, and I got 34 GB.

The preserved space use GiB unit, that is to say 1GB reserved space is 1024 x 1024 x 1024 = 1073741824 bytes
(It's better to change the unit from GB to GiB in the partition configuration diagbox)

Your USB stick's capacity is 128320801792 bytes.
128320801792 / 1024 / 1024 / 1024 = 119.5 GiB
128320801792 / 1000 / 1000 / 1000 = 128 GB
