Grub not finding Windows Partition

Manjaro-i3 on an ASUS Zephyrus G14 w/ Ryzen 9 4900HX, RTX 2060 Max-Q
When running the update-grub script, I get the following output:

Generating grub configuration file …
Found theme: /usr/share/grub/themes/manjaro/theme.txt
Found linux image: /boot/vmlinuz-5.9-x86_64

Warning: os-prober will not be executed to detect other bootable partitions.
Systems on them will not be added to the GRUB boot configuration.
Check GRUB_DISABLE_OS_PROBER documentation entry.
Adding boot menu entry for UEFI Firmware Settings …

/usr/bin/grub-probe: warning: unknown device type nvme0n1.

I can boot to windows if it’s set as the default boot device. From doing other research, here’s some other outputs from commands that are commonly requested:


├─nvme0n1p1 259:1    0   260M  0 part 
├─nvme0n1p2 259:2    0    16M  0 part 
├─nvme0n1p3 259:3    0 805.2G  0 part 
├─nvme0n1p4 259:4    0   900M  0 part 
├─nvme0n1p5 259:5    0  19.5G  0 part 
├─nvme0n1p6 259:6    0 512.7M  0 part /boot/efi
├─nvme0n1p7 259:7    0    16G  0 part [SWAP]
└─nvme0n1p8 259:8    0 111.5G  0 part /

p1 is the windows efi partition
p2 is the windows recovery partition
p3 is the main windows file partition (NTFS)
p4 is an ASUS proprietary recovery boot partition
p5 is the storage area for the ASUS proprietary recovery software.
The other ps are part of the linux install and explain themselves.

Any help would be appreciated. I’m at a bit of a loss.

The disable os prober line fixed it. Thank you.
