Ventoy installation for older and newer systems

[pcpartpicker]

Hello.
I am a PC enthusiaist and I own many older laptops (10-15 years old), as well some older desktop PCs from 2016 year and newer.
I did install Ventoy on my 256 GB USB pen drive with many .iso images, but on some laptops I was unable to run Ventoy normally, due to error messages on pictures below.
I believe issue has to do with either I am booting Ventoy UEFI or Legacy system.
So I need help on how to make installation again so I can run normally Ventoy on older as well on newer systems with UEFI support?

Start by using a smaller UFD for your Ventoy device. There is an old BiOS bug with older Systems that rears its ugly head when you use Ventoy devices larger than (I believe) 138gB. Without available BiOS updates on those machines, the issue will persist.
