HP Notebook 15-f009wm
OS: Windows 8.1 with Bing 32 bit
This is my problem:
I can't get my USB drive to load while in Secure Boot mode and continue running into 'Boot Device Not Found. Please install an operating system on your hard disk' screen. The only method that works thus far is disabling Secure Boot mode and enabling Legacy Support. Here are the methods I have tried based on extensive research of various forums after several days:
- Performed all the generic System Diagnostic tests (F2) + Memtest86 + sfc /scannow multiple times after every fresh install + physically checked HDD. Performed all HP recommendations: http://support.hp.com/us-en/document/c01443463
- 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). 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).
- 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.
- Used 'Rufus v. 2.11.995' software to create ISO as FAT32 under several different setting iterations:
1. GPT partition scheme for UEFI (this presumably should be the most appropriate setting but it still did not work). End Format: FAT32
2. GPT partition scheme for UEFI (once with Dual UEFI/BIOS mode enabled and once again with it disabled). End Format: FAT32
3. MBR partition scheme for UEFI (enabled/disabled). End Format: FAT32
4. MBR partition scheme for BIOS or UEFI-CSM (enabled/disabled). End Format: NTFS
- Hard Reset.
- Disabled Security Boot AND Legacy Support together.
- Tried changing BIOS settings mid-insallation of Windows from Legacy to Secure Boot (right after first reboot).
- Rearranged boot order under every possible configuration. Loaded default settings.
- 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. 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. Press Enter to continue." and it just takes me right back to Boot Manager.
I don't understand what the problem is. I'm using a FAT32 format designed for UEFI as well as GPT partition also best suited for UEFI. I've even created the ISO with both UEFI and BIOS compatibility for each iteration. I've arranged the boot order for USB Flash Drive to boot first. The ISO boots fine in Legacy. What am I missing here?
Thanks for your help.
