creating an iso of Trisquel 10 with MATE Desktop failed

Make sure you have the latest Ventoy setup on your drive, they are releasing several fixed on each version.

I have one pendrive with ventoy and Trisquel 10 boots correctly, I haven't used to install though.

I tried to update Ventoy, but it wasn't possible. Missing file mks....
So I downloaded Trisquel 10 again, in case there is a new version and tried to run it from usb.
It didn't start at all, blank screen.
When I tried Trisquel 10 with the Ventoy usb stick it said no UEFI support. Can it be that the Trisquel 10 iso doesn't support UEFI?

I downloaded Triskel 10 (KDE) and put it on the Ventoy usb stick and also on a separate usb-stick (like I did with Trisquel 10 before) and both failed in opening the iso.

I had also Debian 11 on the ventoy usb-stick and when I opened the iso file, it worked. I would be able to install Debian 11.

So what is the difference between Debian 11 and Trisquel 10 / Triskel 10 ?

I tried with the Ventoy usb-stick to install Parabola, PureOS and it failed also.
When I tried guix it was possible to install guix.

Can it be there is a problem with the new laptop? Interestingly the GNU distributions Trisquel 10, Parabola, PureOS failed, but only guix was possible to install. I bought it with ubuntu installed and added guix. Only Debian 11 would be able to be installed as well.

on an other 6 year old laptop I was able with the Ventoy usb-stick to install Trisquel 9 without any trouble two days ago. After it i updated Trisquel 9 to Trisquel 10 without any problems.

thanks for your help

I tried, what you have said. I created an iso with UEFI-only USB and tried to start it.

The first screen appeared when using the iso, to choose between trying trisquel or installing trisquel.
But when I tried all of them, I heard working the laptop to get started the iso, but there was only a black screen all the time.

So it failed also.

I used different usb-sticks, one with Ventoy to try several isos on an other laptop (3 year old Lenovo)at work.
Interestingly all isos were possible to run. Trisquel 10, Triskel 10, Parabola.

On a 11 year old computer it was the same. Trisquel 10, Triskel 10 isos worked.

So it is clear that my new laptop is the problem.
Could somebody please check if my CPU is the problem, that Trisquel can't work with it?
