Boot from disk drive UEFI - XPS 15 L521x
Hi, I just received my XPS 15 and plan on dual-booting Win 7 and Ubuntu. I'm trying to install both, but I have no disk drive boot option in UEFI mode, only in legacy mode.
How can I boot from a disk using UEFI mode?
Thanks!

Figured it out! As for windows, it would have helped if I had tried it because it does work. As for linux, the boot menu just doesn't look for grub efi on the disk. The solution is to install using bios, then you must boot using efi to install grub, so install refind and use it to boot efi then instsll grub and you're good to go!

UEFI requires GPT -- which isn't easy to set up and may not be supported at all by your Linux distribution. If you want to set up GPT for Windows 7, see the link below - but it'll be far easier to leave the system in legacy mode.

Note: You MUST use the 64-bit version of Windows 7 -- the 32-bit version doesn't support GPT boot,
