Dual Boot Uefi Installation Difficulties

I recently got a new Dell XPS 15 laptop. It has 3 different boot modes: Uefi Secure, Uefi Secure off and Legacy.

When I boot up my fedora live thumbdrive on Uefi secure and off, the installer doesn't detect the hard drive. However, when I set the boot mode to Legacy, and boot using the Uefi USB drive option, and I can install Fedora normally. From here I can create a new partition, add my /, /boot and /boot/efi mount points and complete the installation. When I restart my computer it fails to boot and I can't access windows or fedora.

Thoughts?

Check your BIOS settings, make sure the hard drive/thumbstick isn't set to legacy/compatibility mode and then it should boot under UEFI. Also make sure you have created the USB using a UEFI/EFI image.

I repaired my windows partition and deleted my previous installation of Fedora. I'm booting up the USB drive in UEFI mode (not legacy) and I'm still not seeing the hard drive. When I go into the installation menu it says "No disks detected. Please shut down the computer, connect at least one disk, and restart to complete installation"

I had a similar issue trying to install Fedora on a MacBook Pro and I solved it installing through a DVD media instead of USB Live.

Unfortunately, this laptop doesn't come with a CD ROM bay :/

Mine too, I used a cheap external USB DVD unit from my friend. ;-)
