I'm going to try this to see if it's working when I have a chance
(Guide) How to Create a Windows 7 UEFI Boot Stick
i fresh install windows 7, then i enabled secure boot, then it doesn't boot it says "operating system loader signature not found in secure boot database ('db')" then i disabled secure boot then it boot fine
Other than leaving secure boot disabled, I found this at the link below that may help.

Operating System Loader Has No Signature . . .
these steps resolved my issue:
1. On Startup, press F12
2. Reset Bios to default settings
3. Restart laptop
4. In Bios, select Boot Sequence menu
5. Manually ADD additional line with the name "Windows Boot Manager"
6. Select /EFI/BOOT/BOOTX64.EFI
7. Exit
After I converted from GPT to MBR disk with AOMEI Partition Assistant, can anyone what's that for??
