The Linux USB stick is "magic". Depending on BIOS Legacy/EFI settings it EITHER boots as legacy mode (old small code at start of OS boot partition) OR UEFI mode (code loaded from an EFI partition separate from the OS partition).
You need to have the PC set so that the USB stick boots in UEFI mode, not legacy.
Also the signing etc needs disabled by enable EFI & Legacy modes in Boot. The Boot order of EFI then Legacy then allows bypass of security and repartition of the SSD/HDD. Nothing to do with DEVICE boot order (USB, SSD, DVD, Network etc).
if /dev/sda isn't accessible to Linux live, then you can't install.
SATA0 should be /dev/sda, I don't understand why it's missing from EFI boot list.
