Just so I'm clear, did you use IFL to copy the IFL partition to Free Space on your HD. Did you create a partition for IFL before the copy?
I did create a partition for IFL files called "IFL" (131MB) after "IMAGE" partition. I used Windows File Explorer to copy all files from IFL UFD stick to IFL partition, then I hid it.
When I run IFW v3.02 on Windows 10 Home x64 it shows: Either way, by running it as or double click it brings up that warning... dang! Drive D: (DATA) has full permissions. Only drive C: as usual it doesn't has full permissions by default.
Try this, right click imagew.exe (and imagew64.exe), Properties, Compatibility tab, put a tick in Run this program as an administrator. OK. etc
It's not showing the IFL item which will be called UEFI OS (until you change the name). Have a look in the BIOS and see if you have UEFI OS in the Boot Option Properties. See if you can add it. If not you will have to delete the IFL partition and do an IFW Copy of the UFD partition (not the drive) to the Free Space. It might not like the Microsoft created partition.
I did it but it's still not showing, neither in BIOS nor EasyUEFI obviously. Do I have to copy and set it to active or something in IFW options?
Try this. In EasyUEFI click Create New Entry, Type "Linux or other OS", click on the IFL rectangle to make it go red. File path... Browse to \efi\boot\bootx64.efi OK. Description IFL, OK.
I truly believe IFL partition wasn't detected or seen as bootable in BIOS because it wasn't flagged as ACTIVE.
Excellent. Select IFL, click Set/Unset one-time boot. Power, Reboot, Yes. You should see a script error in IFL.
Neither mine Brian, sorry if I said it wasn't. It's still inactive but just saying my BIOS wasn't able to detect due to the lack of active status. Well I go back on topic LOL
