Sorry for the late reply!

If you want Windows entries not appears in GRUB menu, you can disable
the detection of other operating systems:
chmod a-x /etc/grub.d/30_os-prober
Than you can run update-grub with Windows HDD plugged, and menu will not
include MS/Windows boot.
Usually, when GRUB has no different OS to show in the menu, it's
configured hidden to boot faster. If you want to discover the menu, you
must hold [Shift] key at boot manager stage.
A bit confused here... are you talking about the Ubuntu boot option in
GRUB? No, that in itself was/is(currently) fine and working. The menu
I'm talking about is the BIOS boot device manager/window that comes up
by entering BIOS Boot Options/holding F12 after POST. The entry to boot
to "ubuntu"(The HDD where Ubuntu-Gnome is on) was gone, with only the
HDD model(as mentioned previously) option remaining.
Attempting to boot to the HDD model option after "ubuntu" goes missing
just boots to Windows. I'm guessing that is because it couldn't find an
OS on the HDD so it went to my default boot option, which was my Windows
7 HDD...
AFAIK, my install of Ubuntu-Gnome itself is fine. Every time I've
reinstalled GRUB via boot-repair it always lets me boot back into the OS
with no problems, but eventually goes missing again... even months later
apparently.

Then will you update-grub With or Without Windows HDD plugged?
Without. The test that I just did was without Windows, though normally
it is plugged in during updates.

I suppose the only thing to seem disappeared is GRUB's menu (hidden to

If you already boot to GNU/Linux (Ubuntu), the command "update-grub"
will rebuild menu's entries with plugged volumes that have operating
systems.
I removed my Windows HDD and did update-grub and I can still boot into
Ubuntu Gnome. This is what it gave for output, if it helps any:

Yes it will get triggered by system updates from time to time, so it
would be worth trying and see if breaks things. A reproducible bug is
much
better than one that says "things break after a random reboot"!
Just update-grub? No special arguments/options? I'll try that tomorrow
and see what happens.
Yeah, sorry about that. I said that because I have no clue what
could be
causing it. I hadn't installed any grub updates in a long time and
I've
only recently upgraded the kernel to 4.5, the only times I would think
update-grub would run.
I swear this has happened without even installing updates before
though.
Guess I'll found out tomorrow when I run it...
I run Windows 7 and Ubuntu Gnome on separate hard drives. I had
unplugged the Windows 7 HDD for the boot-repair.
Don't think so since it happens when restarting from Ubuntu Gnome
and
never from Windows 7 to Ubuntu Gnome if the option was there before
restarting Ubuntu Gnome.
OK, its probably not from windows then
If it matters any, I get a duplicate UEFI entry for Ubuntu, named
after the hard drive model(Model: ST3750528AS). If i select it, the
screen
flashes blue and enters grub as normal(or looks normal, anyway).
I don't have any UEFI hardware still, so not entirely sure about
this.
But I believe the UEFI entries are added by the OS, maybe you can use
efibootmgr to remove the dupe. No idea if this is causing your issues
though.
