I am trying to roll out Zorin OS in my club on some HP Compaq 8200 Elite SFF PCs on which a Win10 is still installed. The usb boot stick (created with Etcher and Zorin OS 15.3 Core) is not showing up in the boot menu. So I have selected “Run UEFI Application…” and selected USB->EFI->BOOT->GRUBX64.EFI.
The grub screens starts and show the different booting options, e.g.
- Try or Install Zorin OS
- Try or Install Zorin OS (safe graphics)
- Try or Install Zorin OS (nvidia)
I tested all options and all of them result in a black screen (with no mouse showing up).
I tested the Live USB Stick on a old Fujitsu Lifebook as well as on a new HP Spectre and there the “Try Zoring” works perfectly.
I disabled all security options in the BIOS of the HP Compaq and tried again without results.
I found some related posts but no solution of them worked:
- When I click Try or Install Zorin OS it brings me to a black screen
- [SOLVED] Black screen after install
Any help is very appreciated.
