grub "sytem setup" entry lost

[alexnt]

I did the latest updates on my linux mint and after reboot, I noticed that "system setup" entry on grub is missing. Any ideas?

The first thing you should do is make sure you're booted via UEFI still. One of the updates may have broken that. If you have confirmed that you are booted via UEFI you can add this to your grub.cfg:

menuentry 'System setup' $menuentry_id_option 'uefi-firmware' {
    fwsetup
}

Reboot and the option should appear. Let me know how it works! ~Breadpudding

Edit: This was found in the grub.cfg on my Debian system. Compatibility may vary with Mint.

I launched grub customizer to add the script and I saw that the entry was there at the bottom of the list, I 'm 99% sure there wasn't the other day. So, I just saved and closed the program than just closing and then rebooted. The entry was there this time.

Thank you for your time.
