I'm about to go crazy.  I've reloaded my Precision 3630 with a fresh Windows 10 install but after it reloads, it will not boot!  I've tried UEFI and Legacy and installed them in different ways about 10 times.  I've played with all the settings I could find and from recommendations I found in this forum.  Turning on settings like Secure Boot, AGHI, RAID, etc... No luck! 

In the BOIS, I can see my drive listed in SATA section, but it is not listed in the boot order and I cannot add it.  I only have options to boot from NIC, USB or Diskette Drive.  I even tried using an NVMe drive.  That loaded right up...but no way to boot to it and it's also not listed in the boot order options. 

I can also completely install Windows 10 off a USB but when it's done it comes up saying it cannot find a boot drive.  I can get it to boot up windows IF I leave the USB in the drive.  What is going on??  Why isn't my drive seen in the BIOS boot order?   I've never seen this before. 

I've also updated to the latest BIOS version.  Maybe that messed up it up?
