Os-prober, and grub can't find windows 10

Sorry if this sounds similar, but I don’t really know what UEFI or the other boot things are.
I installed Manjaro on sda while windows is on sdc, but grub never shows up. I can pick windows in the boot menu so I know it’s not delete. From what I have read it might be some about UEFI, but I don’t really understand what that is or how to tell if I have it or not. Thank you for your time.

Do as suggested on the update announcement:

I just get permission denied.

I had the same issue, this is what I did:

su root
echo GRUB_DISABLE_OS_PROBER=false >> /etc/default/grub && sudo update-grub

It all seems to work now

Well, look at that… it looks like manjaro-system-20210321-2-any checks / re-enables os-prober…

    'os-prober' was already enabled by the user.

Yep, I noticed that yesterday when I updated my parents computer, it re-enabled os-prober by itself according to the terminal output.
