Dell Precision 7760 with integrated intel graphics only with OEM Ubuntu default installation on arrival (no Nvidia, etc). Latest bios (1.7). Intel xeon with 128GB ECC RAM.
Disabled secure boot and played with bios settings for long time.
Qubes 4.1rc3 and Qubes 4.1rc4 both fail to load at installation.
After spending few hours trying to follow the unfriendly instructions on how to edit the non-existant BOOT64.cfg file I have given. up.
Do not buy this machine if you want QubesOS support.
Because I can not get installer to load I can not do a proper HCL.
