XPS 13 9360 - Diagnostics does not recognize PCIe Drive in Legacy Boot

Hi,

I have an XPS 13 9360 that I wanted to use to test and run diagnostics for several PCIe drivers. My current setup involves a Plextor PCIe drive that I use daily. 

Before I put in one of the PCIe drives to test, I ran the diagnostics (Press F12 during boot to get there) on my current drive to see how it goes. But when the diagnostics get to the hard drive test, it skips it saying "Hard Drive Not Installed". 

The drive I have boots up perfectly fine with the current settings with legacy boot. Is it because the test will only detect drives with UEFI enabled? The problem is that when I upgraded my drive, I could not find a way to boot up with it in UEFI mode. After installing Windows on the PCIe drive (I upgraded from a normal m.2), I tried enabling UEFI mode but every time it would fail to start up also saying "Hard Drive Not Installed". So I just left it in legacy mode.

I'm not aware of any available M.2 NVMe to USB adapters that would simplify this for me but I was wondering if anyone else ran into any troubles doing the diagnostics with a PCIe drive? I'm sure the XPS 13's that come with PCIe drives are configured properly though. Not sure how to get mine working in UEFI mode. Any help is much appreciated

PCIe drives normally require the UEFI configuration

You actually HAVE to turn off secure boot and switch from UEFI to Legacy in order to upgrade from the regular M.2 to PCIe. When you install Windows, the UEFI partition is supposed to be installed allowing you to switch back from Legacy to UEFI.

But regardless, detection and even use/boot into windows is completely fine in Legacy. But the diagnostics seems to be unable to pick up the PCIe at all.

Since I have no experience with your system, I cannot say for sure, but there was another thread which indicated a PCIe  or its SATA version was accessible or not accessible depending on if you had AHCI or RAID enabled.

As for me, there is no reason to turn off UEFI unless you need to boot something which is not UEFI capable.
