I download the latest Clonezilla put it on USB stick with Rufus (MBR, BIOS or UEFI but tried GPT, non CSM too), it works on some of the devices and it freezes on others after selecting mode. I tried different vga modes, not all of them of course.
The BIOS on the ones it works on lets me set Disabled under Boot / CSM Support, the ones it freezes on there's only "Boot option filter" UEFI and Legacy, Legacy only, and UEFI only with 3 extra lines under Boot "Launch Storage OpRom policy, Launch Video OpRom policy, and Other PCI device Oprom priority. I'm pretty sure I tried almost all of the combinations. No BIOS update possible the board is a no-name no-support board.
What can I try?
