My system has Windows installed on a 500GB Intel 660p SSD, and a 1TB HDD purely for storage, that is currently empty.
When installing Ubuntu off a flash drive, if I use the "Install Ubuntu alongside Windows Boot Manager" option under Installation type, the next screen only gives me the option to partition off some of the HDD. In the drop down menu for select drive, the HDD is the only option.
If I use the "Something Else" option, the SSD shows up, but this is a more complicated screen, where I have the option to select either entire drive or 1 of the 4 partitions, I'd rather figure out why the simple install can't be done on the main drive.
The SSD also shows up fine when browsing in Ubuntu (running it off the flash drive).
