I've looked through many problem solving techniques for similar problems, but with my set-up it appears none of them are quite relevant.
My computer is a HP Envy Phoenix with 3 drives installed: 128GB SSD which my Windows is installed on, 2TB Drive which I generally install programs on and use for storage and a 1TB (Previously completely empty) drive of which I recently installed Ubuntu 14.04 on.
The issue I am now faced with is that the BIOS menu is no longer showing the 128GB drive to boot off at all, meaning my Windows drive has completely vanished. Funny thing is, when I use Gparted or even go to re-install Ubuntu, the 128GB drive appears. (Although in the Ubuntu installer it doesn't show it to be the host to Windows OS).
When I installed Ubuntu, I installed it on the previously stated 1TB COMPLETELY CLEAN drive and did not do anything to any of the other drives. I split it in half, using half for the Ubuntu OS and the other half for the prerequisite "swap" section.
The Windows OS does not show up in the Grub 2 either.
I feel the issue is that Windows is booted on Legacy and Ubuntu boots on UEFI, yet in the BIOS the drive doesn't even appear under the Legacy tree.
Does anyone know how I can boot Windows 7 again (without re-installing/doing the fix with a Windows 7 installation disk)?
Now, on a different thread, it is said that I have "mixed" BIOS installs and are best to re-install one of the OS's so that they are both on the same BIOS. Which begs the question to me (not being able to navigate the Ubuntu installer efficiently) how do I install Ubuntu on the correct BIOS setting? Thank you for your time
EDIT: I have re-installed Ubuntu onto the drive with a 16GB /boot area and a 16GB swap area. The rest of the drive is now for Ubuntu.
