GRUB update not working

[Joesplace]

I am adding a new drive to a Windows 11 computer with Zorin 17.3 installed on it. I am booted into Zorin and run a terminal command to add Windows. When I use "sudo update-grub" it will not add my Windows 11 drive to grub. The message says "Warning: os-prober will not be executed to detect other bootable partitions. Systems on them will not be added to the GRUB boot configuration.

Oh, sudo fdisk -l does detect my new drive.

Any Ideas on how to add Windows 11 or why this won't work?
thanks . . .

sudo nano /etc/default/grub

Uncomment (remove the hashtag symbol):
#GRUB_DISABLE_OS_PROBER=false
Leave set to false.

ctl+o to overwrite, enter to save configuration, ctl+x to eXit the editor.

sudo update-grub
