Optiplex 5260 AiO - New Windows 10 installation
Hoping someone can help me before i send these machines back to Dell.
Brand new 5260 AiO. First Dell BIOS I've seen where you cannot access the internal HDD/SSD through legacy BIOS boot options, but should be fine. Or so I thought....
BIOS is set to UEFI. Secure boot is switched off legacy ROM options enabled so I can press F12 and boot from USB to install OS
Trying to do a core, security baseline build of Windows 10 Pro. Deleted all existing partitions. Booted from a Rufus win 10 ISO bootable USB key. shift+f10 diskpart > set disk to GPT and all that jazz. Installed Windows 10. Remove USB key and restart.
No bootable devices found....
Go into BIOS. Notice that under UEFI that Windows Boot Manager is not there. Nothing, nada. zero. Click "Add Option" button and get error "File System not found!"
**bleep**!?

According to reports here, newer/latest versions of UEFI BIOS are getting further locked-down industry-wide (ie SecureBoot, etc.).
No Rufus.
Just use USB flash created directly from microsoft.com ISO tool. Bare-metal install to blank/raw HDD/SSD.
