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 ?
from my initial installation-report:
"when install was finished, a list of drives was displayed, asking where
to install GRUB.
the install drive was highlighted
I selected the drive with bios_grub
the display showed "installing GRUB on (...drive it was installed on...)"
Pardon me for not being more clear. I will elaborate from the photos I took
"Install the GRUB boot loader" menu ... 6 items
Enter device manually
/dev/sda (usb-SanDisk ...
/dev/sdb (ata-WL4000G ...
/dev/sdc (ata-WDC_WD300...
/dev/sdd (ata-WDC_WD300...
/dev/sde (ata-SanDisk_SDSSDA240G_162248447811)
I selected /dev/sde and pressed the Continue button
then the GUI progress bar Installing GRUB and I see Running
"grub-install /dev/sdd" ...
in this case sdd was the install location, sde is the drive that has a
bios_grub flagged partition
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.
Yes, that is from the BIOS
