I built a system in 2014 that had Windows 7 running in Legacy BIOS mode. After a few years I upgraded it To Windows 10 with UEFI BIOS mode, then I downgraded again to Windows 7 in 2018. Now I tried to install Windows 7 OFF A USB DEVICE, and it fails to install. I get an error message "0xc0000225".When I created the Windows 7 installation media with Rufus, it said that I have to disable Secure boot to use UEFI:NTFS boot. But I didnt find any option foe it. So I changed it to Fat32 UEFI but Windows wouldn't still install, I get the same error message. I tried to boot the flash drive in my new pc and it works flawlessly in both NTFS and Fat32. I HAD ANOTHER WINDOWS 10 USB IN UEFI:NTFS THAT WORKED IN THE PC I WAS HAVING TROUBLE.
So I want to know why is the error message appearing
Note: (i) My old PC was downgraded to Windows 7 Legacy BIOS in 2018. So I think secure boot was off as I read somewhere that Secure Boot is available in UEFI only
(ii) When I upgraded to Windows 10 I used UEFI NTFS so I can tell the PC supports UEFI
