Loading Fedora 42 from another Linux grub.cfg

Ask Fedora

Hello everyone, I am back to RH environment after early involvement many years ago. It seems things have changed a lot.

I have a multiboot system with Win 10, Zorin, SUSE, Manjaro and recently Fedora 42.
All of them can start directly from Win 10 BCD, except for Fedora.
Fedora 42 is not automatically recognised by any of the other systems either.

I would be grateful if anyone could suggest a working structure of a menuentry{ } for Fedora 42 that may work, say, from 40_custom on a standard Linux.

My system is BIOS/MBR, Fedora in two partitions ext4 and btrfs.

When Fedora installed it should put BLS (boot loader spec) file into /boot/loader/entries.
grub knows how to read all the files in that folder to construct the boot menu for Fedora.

The file contains the grub command lines used to boot a Fedora system.

Thank you for an important piece of information.

Issue resolved.
