I have a ROG Strix G712L. 32Gb RAM 2 x 1TB - M.2 NVMe drives NVidia 2070 Win10 Home
I have upgraded the laptop to Win10 Pro (keeping all the data, not wiping Win10 Home), Secure Boot was disabled during upgrade, and everything was fine. After a few days I decided to reinstall Win10 Pro (again not wiping the drive) because I had some networking issues (after doing a Win 10 debloat). This time I forgot to disable Secure Boot before doing the reinstall and although the reinstall was just fine when I tried to reboot it wouldn't. It stops after about 5 seconds just after the ROG logo appears. I can access the boot menu so disabled Secure Boot but still won't boot. I enabled it, no boot.
Then I booted from a USB stick, no problem, the PC is working.
Then I installed Win 10 Pro on the other drive I had in there (clean install as that drive was brand new), I disabled Secure Boot before doing the installation, and the PC boots just fine from the second drive. I can access everything on the first drive, so the drive is fine. My question is how can I make the fist drive boot again? I suspect the non-boot issue is caused by me not disabling Secure Boot BEFORE re-installing Win 10 Pro on the first drive.
Google search only brings up instructions about how to enable / disable Secure Boot, which I don't have an issue with.
I presume I could wipe the first drive and re-install Win 10 Pro that way but I prefer to keep everything on it.
