T7600 Won't Boot from USB

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?

I found a solution.  When I wanted to reinstall LINUX (Ubuntu Studio) on a dual-booting T7600 the USB option was not visible.  Eventually I found an entry for the LINUX efibootmgr program which might have solved my problem, but it made me think about a solution using only the BIOS.  The solution may require that the "grub-efi" boot manager has been installed.  In my case I discovered from "efibootmgr" that there was a "USB Storage Medium" entry in the BIOS which was not enabled.  I did F12 into the BIOS which was in UEFI mode and then selected to add an entry.  In the window that opened there was a button to select a file which started with "EFI" but when that was entered I saw my LINUX OS as a label - "ubuntu" and in that there was the file "grubx64.efi".  I selected that and used the name "USB Storage Medium" as listed in the "efibootmgr" list and the USB option appeared in the UEFI boot list.  I applied and exited and I'm writing this after booting into the USB stick.
