I installed with what I thought were the recommended partitions but I think I may have done something wrong. I'm not loading windows or any other OS and I don't have anything indispensable on the computer. I tried reinstalling trying to use as many default settings as I could. For awhile there it only booted into BIOS and all of my boot options were missing but it would work when I booted with the ubuntu live usb inserted. Fiddling with the settings I can create a new boot option but I don't know where the path is located.

I can reinstall, repartition if I need to.

To clarify booting in CSM mode gave me back an insert bootable disk and retry error. in the boot options I have no options. I reinstalled using UEFI, same problem. Boot repair is currently hung at "purge and reinstall GRUB of:sda3(upd) http://paste.ubuntu.com/11879419/

You have newer UEFI capable hardware, but installed in CSM/BIOS boot mode. CSM - UEFI Compatibility Support Module (CSM), which emulates a BIOS mode

You then always need to boot in CSM mode, not UEFI nor UEFI with secure boot on. Only in CSM/BIOS mode. It looks like you booted Boot-Repair in UEFI mode & it tried to repair for UEFI boot, but without efi partition it cannot fully fix it. You should just be able to boot in BIOS mode?

Hold shift key to get grub menu as with one install it will not show menu normally.

What brand/model system and what video card/chip? If you get grub menu you may need video boot parameters.

My computer boots to a black screen, what options do I have to fix it?

Or you can reinstall in UEFI mode, you could convert existing swap to efi partition, FAT32 with boot flag to be the ESP - Efi System Partition and add swap at end of drive. You have to be sure to boot installer in UEFI boot mode to install in UEFI mode.

Also shows Windows 8 screens, which you do not need, just skip that part.
