Update GRUB Configuration File - Rescapp - Documentation
Newest computers start up thanks to the newest (from 2015 onwards) UEFI boot system.
Older computers start up thanks to the old BIOS boot system.
Later on the boot process is delegated into GRUB. GRUB has its own menu system. You might be lacking some distributions entries or some Windows entries.
This option rescans your Operating Systems and updates the GRUB menu accordingly so that other distributions and Windows appear again.
