I have a thin client Wyse D90D7. It can't boot Lubuntu and any other linux distro 64-bit that doesn't have UEFI-CSM. it always get stuck on black screen without error. Installing 32-bit is not an option because some softwares I use no longer support 32-bit and the hardware is based on 64-bit. Linux Lite 64-bit with CSM support and Windows 10 x64 boots perfect but it's running slow so I prefer Lubuntu on thin client.
I used Rufus and it does tell if ISO have UEFI-CSM or UEFI only
Is it possible to add CSM support on bootable USB?
