I'm having the same issue. I haven't been able to boot the 4.0.1 installation with UEFI on my Dell XPS 15 9570 w/ 4k/NVMe/1050Ti. It doesn't look like anyone else has either. A screen briefly pops up saying Xen EFI and then it reboots. I am able to complete the installation booting from legacy boot mode but I am still unable to boot from it. I am not getting to a grub menu. "No bootable device found". Seems odd because Ubuntu/Fedora liveCDs boot fine with Dell's UEFI.
I previously installed Qubes on a USB drive for testing and was able to boot into Qubes just fine, it was just too slow. I've tried every step listed on the UEFI page as well as the Thinkpad UEFI troubleshooting page. Any suggestions on where to go from here besides selling my laptop? For anyone else with this issue, to get through the installation: Enable Legacy Options ROMs, Disable Secure Boot, SATA ACPI mode, installation kernel parameter nouveau.modeset=0. The efibootmgr fix doesn't work in rescue mode, I think that's due to not loading the install via UEFI. efibootmgr will run fine from another liveCD booted through UEFI but it doesn't seem to help. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
