Well I have managed to get rc4 installed in UEFI mode, but it's not a nice process :) The Qubes iso seems to contain two menus for EFI booting, but the Dell XPS15 won't display them at all, hence there is no possibility to edit the boot line and add the modprobe.blacklist option at bootup. There are two ways I've found to overcome this - in one, I edited the Qubes iso file before writing it to a usb stick, and the other was by following the Lenovo troubleshooting link, https://www.qubes-os.org/doc/thinkpad-troubleshooting/ 1. Binary edit the Qubes iso (I used gvim as plain vim could not handle the temp file!?!). Search for "i915.preliminary_hw_support=1" and REPLACE it with the string "modprobe.blacklist=nouveau ". This MUST be exactly the same length as the i915 string, so it add three spaces at its end. ANY change in the length of the text line will damage the iso and it definitely won't work. This probably only needs to be done for the "qubes-verbose" menu options, but I didn't check this, I just replaced all the repeats of the string in the two menus. There is a third menu for GRUB legacy, but I did not bother replacing them there. Then write out the iso to usb, and reboot. Interrupt the Dell boot screen with F2 and select the UEFI usb boot option. All should work OK. (Qubes-check will fail because the iso has been edited, but the check option only appears when legacy booting.) 2. Or, follow the Lenovo troubleshooting guide at the link above, and create the usb and change the Label to BOOT and mount it. I could not find the xen.cfg file, but there was a ".cfg" (can't remember the name) that contained the bootup command lines. I replaced the option "quiet" with the modprobe.blacklist=nouveau string. Length of the string does not matter in this case. Save the file, unmount the usb and try to boot from the it. It didn't provide an UEFI boot option on my DELL, but I was able to boot the "fallback boot on Anaconda" from my boot manager "refind". You may not want to go to the trouble of installing that if you are not multi-booting your laptop. In which case, you only have option 1. Some of the problems with the Dell (apart from the nVidia device), are that it seems to require that any EFI partition must have both the correct partition type (EFI) and the specific EFI disk identifier, otherwise its bios does not recognise an EFI boot partition.
