I have an ASUS ROG G75VW. I've installed a SanDisk SDSSDA-240G to which I cloned an image of my previous HDD. However, the SSD does not show in the Boot Menu as a bootable device. I've had the SSD in both SATA ports, I've removed the previous HDD, I've updated the BIOS.

Any idea how I can make the SSD show up as a bootable device?

Then you did something wrong.
Assuming the original drive is still bootable, redo it.

Like this:
-----------------------------
Verify the actual used space on the current drive is significantly below the size of the new SSD
Download and install Macrium Reflect (or Samsung Data Migration, if a Samsung SSD)
Power off
Disconnect ALL drives except the current C and the new SSD
Power up
Run the Macrium Reflect (or Samsung Data Migration)
Select ALL the partitions on the existing C drive
Click the 'Clone' button
Wait until it is done
When it finishes, power off
Disconnect ALL drives except for the new SSD
Swap the SATA cables around so that the new drive is connected to the same...

Swap the SATA cables around so that the new drive is connected to the same SATA port as the old drive
Power up, and verify the BIOS boot order
If good, continue the power up

It should boot from the new drive, just like the old drive.
Maybe reboot a time or two, just to make sure.

If it works, and it should, all is good.

Later, reconnect the old drive and wipe as necessary.
Delete the original boot partitions, here:

In thinking because I didn't clone ALL the partitions, my BIOS didn't recognize it as a bootable drive.

But yeah, after running the process again and cloning the drive in its entirety, it worked just fine.

Thanks!
