I downloaded a Windows 8.1 Single Language 64 bit ISO strictly as a test (as Microsoft doesn't make Bing version available (yet?) for download), used Rufus to set partition scheme to GPT for UEFI and file system as FAT32 and created the new image. ' 32bit is unable to boot on a UEFI GPT disk computer.

The problem lies in the 32 bit version of Windows I had installed: Okay, thanks to another user from another site I had posted on, I received the answer I was looking for and am posting it here for anyone's future reference. I've arranged the boot order for USB Flash Drive to boot first. I've even created the ISO with both UEFI and BIOS compatibility for each iteration. I'm using a FAT32 format designed for UEFI as well as GPT partition also best suited for UEFI. Press Enter to continue.' and it just takes me right back to Boot Manager.

Once INAB is enabled, the flash drive is recognized and allows access to the files in the folder but none of the files will boot as the next screen that pops up every time states: 'Selected boot image did not Authenticate. With the Internal Network Adapter Boot disabled by default in BIOS while in Secure Boot mode, the flash drive won't even read in F9 Boot Manager. Rearranged boot order under every possible configuration. Tried changing BIOS settings mid-insallation of Windows from Legacy to Secure Boot (right after first reboot). Disabled Security Boot AND Legacy Support together. MBR partition scheme for BIOS or UEFI-CSM (enabled/disabled). MBR partition scheme for UEFI (enabled/disabled). GPT partition scheme for UEFI ( once with Dual UEFI/BIOS mode enabled and once again with it disabled). GPT partition scheme for UEFI (this presumably should be the most appropriate setting but it still did not work). 2.11.995' software to create ISO as FAT32 under several different setting iterations:ДЎ. Used 'Windows 7 USB/DVD Download Tool' to create ISO which automatically formats drive to NTFS converted to FAT32 using 'AOEMI Partition Assistant' software (preserving all partitions/data) but it still won't read. Installed using Legacy Support (I understand you can't go back and enable Secure Boot and disable Legacy once it has been installed this way but due to lack of any other way of installing Windows, I have no choice). Did multiple fresh installs of Windows 8.1 with Bing (32 bit) erasing all partitions from hard drive every time (my system is designed for 64 but I only have access to a 32 ISO). Performed all the generic System Diagnostic tests (F2) + Memtest86 + sfc /scannow multiple times after every fresh install + physically checked HDD. Here are the methods I have tried based on extensive research of various forums after several days: The only method that works thus far is disabling Secure Boot mode and enabling Legacy Support. Please install an operating system on your hard disk' screen. I can't get my USB drive to load while in Secure Boot mode and continue running into 'Boot Device Not Found.
