The next time you run grub-update that will be obliterated. You should put that into an appropriate file in /etc/grub.d so it will get added to /boot/grub/grub.cfg by grub-update. > > deb12 installer is buggy, perhaps it is confused by 3 disks(2 sata > disks and 1 usb installation stick) ?

The live CDs provide a different installer; I have do idea what that does. > > old wisdom of dual boot still works Good. -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
