This is completely different from what I understood.
The statement "GRUB does not get installed at all" is refuted by
/var/log/syslog which indicates clearly that GRUB was successfully
installed on /dev/sdb:
Apr 28 23:55:51 grub-installer: info: Running chroot /target grub-install --force
"/dev/sdb"
(...)
Apr 28 23:56:01 grub-installer: Installation finished. No error reported.
Can you described what happened exactly ?
Were you prompted to "Install the GRUB boot loader to your primary
drive?" ? If yes, did you answer "yes" or "no" ?
Where you then prompted to select the "Device for boot loader
installation" ? If yes, what option did you select exactly ?
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."
If this is a message from the BIOS, then it is flawed. A compliant BIOS
should not care about the partition table, even less the presence of any
kind of partition. All a BIOS should care about is the presence of the
"boot signature" 0x55, 0xAA at the end of the boot sector.
