-# GRUB: Incorrect Linux version `booting Linux linux ...`
+# GRUB menu: Linux version not detected
-If for some reason your grub installation doesn't detect your Linux version
-properly, and displays it wrong or as `Arch Linux with Linux version linux` like
-in my case, you can solve it modifying the following files.
+If your grub installation doesn't detect the Linux versions properly, and
+displays it wrong in the prompt menu at boot, like in my case in which appeared
+as `Arch Linux with Linux version linux`, you can solve it by modifying the
+helper scripts which grub uses to build the configuration file.
The problem is cause by the script `grub-mkconfig` which is used to build the
grub configuration file `grub.cfg` (generally located on `/boot/grub/grub.cfg`).
-This script uses other helper scripts located on `/etc/grub.d/`, and in
-particular the file used to detect the Linux version is `/etc/grub.d/10_llinux`.
-This script uses the file name of the kernel for which the menu entry is being
-built (for example `/boot/vmlinuz-6.1.0-25-amd64`) to get the Linux version, but
-there are distributions like Arch Linux that doesn't add the suffix of version
-to the kernel file (for example `/boot/vmlinuz-linux`).
