Unable to install / VMD help

I agree.
If you cannot start the USB, try to e.g. recreate it with balena Etcher or Ventoy.
If you installed, but the installed system doesn’t boot, check here

If that works, but you necessarily need vmd (sometimes needed for dual booting), there are several posts about it. E g.

If you don’t know how to chroot, there’s a tool in the live USB or a tutorial in the forum.
