I need to re-install/repair Windows 10 on a T7600, and have had no success.

Installation Medium

1. Using the Microsoft Windows Media Creation Tool, it automatically formats the USB in FAT32. 
2. I have also used Rufus to force an NTSF format as directed by Microsoft Tech.
   1. Partition Scheme: MBR
   2. Target System: BIOS (or UEFI-CSM)

Hardware

• stripped down to a keyboard, monitor, and ethernet 
• PERC H310 Adapter having SSD at RAID 0 having damaged Windows 10 registry file

BIOS Version = A17

• tried both Legacy and UEFI
• 'advanced boot options' does not exist
• there is no secure boot toggle option

Processes Attempted and Results

Using NTSF USB

1. no boot sequence is found under UEFI
2. RAID Adapter turned off from 'Boot Sequence'
3. under 'Legacy', it boots to a 'Press any key to boot from USB'
   1. it responds to a key being pressed, but resorts to booting up using the RAID adapter 

Using the FAT32 USB

1. The Boot Sequence discovered & shown as UEFI: INT13(,0x83)
   1. File Name was " " and not editable
   2. "No bootable devices" is found
2. Created a 'Boot Option' with the file \BOOTMGR.EFI in the main folder of the Windows 10 USB
   1. de-selected the the self-discovered UEFI option (option #1 above) from the boot sequence
   2. didn't work
3. Created a 'Boot Option' with the file \EFI\BOOT\BOOTX64.EFI
   1. didn't work

The only other EFI files on the USB drive are memtest.efi, cdboot_noprompt.efi,cdboot.efi.

I'm at a loss.  I have installed/re-installed Windows 10 before on the same T600 machine, but can't recall what settings were used and it may have been a previous BIOS version.

Has anyone had recent success, and how did you do it?
