How to edit grub for boot switch?

Chernenko

Hi,everyone.

My computer have two solts for SATA,my first install Batocera on sda,after 1 moons (today) I'll buy a new disk and install Manjaro-Xfce,seens on sdb.

I'm installed grub-customizer for search another boot,but it's not work.For now I want to boot on Manjaro's grub and after seconds try to load Batocera,have somebody to tell me how to do?

I'm not sure if Batocera upgraded the grub.cfg on sda1 can keep right,so I want boot from sdb.

Thanks.

GameCast This can't help for me,bro.
My computer all system are Linux,with out Windows.
I seens just change my 2rd system grub.cfg and use it for boot batocera.
I try to copy info for Batocera's grub.cfg,add "set root='hd0,mbr1'" or add not,whatever that's not work,seens like can't find files and kernel not loaded.

GameCast Don't mind bro.
I'll try again it,because that's can made one manchine have two useful,and if I want add a game just switch system to download and unpack it,or reback partition when Batocera crashed.
For now?Just use BIOS to switch Batocera and Manjaro,I know it's seens stupid.
