I'm having trouble dual-booting 12.04 alongside Windows 8. It's a self-assembled PC, so there's no OEM UEFI or anything like that (just to be safe, I checked the BIOS settings and it was set to legacy). So the problem is I boot from the live DVD, allow Ubuntu to carve out its own partitions (by selecting "install alongside Windows 8"), it proceeds to a screen where it tells me installation was successful, then a message pops up saying
"Executing 'grub-install /dev/sda' failed. This is a fatal error."
So I chose to finish the installation without a bootloader. Before I go further, here is the return for fdisk -l:
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sda1 1 1953525167 976762583+ ee GPT Partition 1 does not start on physical sector boundary.

I have it set up so that /dev/sda is my storage HDD with files accessible by both Ubuntu and W8. /dev/sdb is my SSD that I want to run both OSs on. /sdb1 is my existing Windows installation, sdb5 is the currently unbootable 12.04 installation, and sdb6 is swap.
What I have tried so far is deleting the partitions and redoing the whole thing, except initiating it by running
ubiquity --desktop %k gtk_ui
in sudo. No change in behavior. I have tried running grub-install in sudo and it completes successfully. However, when rebooting it boots what I would assume to be the GRUB terminal. Obviously the GUI form is preferable. Anyway, I'm a Linux noob, so I'm open to suggestions.
