Fw: Fw: Grub cannot see my new hard drive
The internal hard drive was visible to Grub, as was the other external USB hard drive, a Western Digital drive. Having an external hard drive connected with USB is not the problem. Grub was on /dev/sda and used to boot the Western Digital drive just fine, until Grub was reconfigured to boot the Toshiba hard drive instead.

If I'm reading things correctly, this "Toshiba External USB 3.0" -
labeled here as /dev/sdb - is the drive which is at the core of the
reported problem.
I'm wondering whether the fact that it's an external hard drive,
connected over USB3, might be relevant to the fact that GRUB and the
BIOS are not detecting it.
There are systems out there which have some of their USB ports hanging
off of an internal USB hub chip, such that in order for the ports to be
visible to the rest of the system, a driver for that hub is needed. If
GRUB etc. doesn't have a compatible driver for that hub, the USB port to
which this external drive is connected might not even be detected in the
first place.

That's *probably* not a problem relative to the fact that this is a USB3
external hard drive, but it certainly can't be helping.

Unless I'm mixing up my reading of the information posted thus far, this
is the internal hard drive, /dev/sda, which has Windows - not the
/dev/sdb which has Linux. As such, I don't see how it's relevant to the
fact that the latter is not visible to GRUB.
