Hi! Welcome to the forum! :enos:

Is your issue because grub is not running os prober? 🤔

You may try this:

```auto
sudo nano /etc/default/grub

```

Go to the end of the file, and type this in a new line:

```auto
GRUB_DISABLE_OS_PROBER=false

```

`Ctrl + s` to save

`Ctrl + x` to exit

Now update Grub configuration:

```auto
sudo grub-mkconfig -o /boot/grub/grub.cfg

```

It may take some time because os-prober is slow. Be patient!
