The GRUB which was previously installed on /dev/sdb ?the GRUB that was on the only disk with a bios_grub flagged partition.Thank you for the clarification. If I understand correctly, - the machine usually boots with some GRUB on disk X, - you installed a new Debian system with GRUB on disk Y, - then the machine rebooted on disk X as usual.
Correct: to reiterate the problem... DI asks on which drive to install GRUB User says disk X DI attempts to install on Drive Y result ... GRUB does not get installed at all
The Debian installer will not add the newly installed system to another existing OS GRUB menu; it will only add other existing OS's to the new installed system GRUB menu, which will be displayed only if the machine boots from the disk containing the new GRUB. So what you describe is normal behaviour.
"normal"?except I am not asking for the existing GRUB menu on drive X to be appended.
the request is Install GRUB on drive X
If you want to add the newly installed system to another OS GRUB menu, you need to run update-grub from that other OS. If you want to boot with the new installed GRUB, you need to set up the BIOS to boot from the disk which contains it.setting up BIOS to boot from a drive that does not have a bios_grub flagged partition results in:
"GPT-formatted disk. Legacy boot not supported. Press any key to reboot."
