Grub does not detect windows on another disk.

[isXander]

Grub bootloader does not detect my windows installation. Windows is installed on a different disk than grub. Am I right in thinking that grub does not search for installs on different disks?

Windows is mounted to /run/media/isxander/Windows. I have used update-grub and os-prober but nothing works.

 

Edit: I have had problems with grub in the past. Manjaro made grub hidden by default. Also, when peeking in grub.cfg, a lot of things are uncommented when they said uncomment if which suggests manjaro  has changed it quite a lot

 

Edit 2: I am new with linux so I am not comfortable with changing configs unless it is step-by-step (hope you understand)

Try rEFInd, see if it detects your Windows EFI file though.

grub.cfg may have to be edited manually.  See this thread in another forum. 

Apparently an issue I have seen asked elsewhere, too

If your Windows install is uefi you need to use grub-uefi and not grub2 and vice versa.
