Unable to get GRUB to recognize Windows install

I got Ubuntu Budgie put onto my friend’s computer on a separate drive and I am unable to get GRUB to recognize the Windows install on the Windows boot partition. When I am trying to get the OS-prober to detect it in the terminal, it is not producing anything. He has not used Linux at all before and that was why I was going to have a dual-boot for him, I had just switched the boot priority in the BIOS to be on the Windows one while I’m trying to figure it out. I was originally going to use the Windows Subsystem for Linux to enable him to just use Ubuntu within Windows, but it was not producing any GUI for him, it was only the terminal that was showing. The WSL also was only allowing up to the 20.04 LTS release of Ubuntu, not even the 22.04 LTS, which was odd.

This is a generic Ubuntu install issue - you should also ask this on the wider ubuntu community forums askubuntu.com and ubuntuforums.org
