That's exactly the settings I have. I think I have figured out the grub issue, well, kind of figured it out.
I installed yesterday and everything went great. I rebooted multiple times and was so excited to finally be back up and working that it it dawn on me to make sure grub was actually installed to the MBR of the drive I was using. I wiped the other drive that I had windows on and then I couldn't boot. No bootable disk. Hmmmmmmm.....
I went in via chroot and tried to reinstall grub but kept getting an error so I said screw it and I reinstalled. I disconnected all unnecessary drives as to eliminated any possible headache. Everything went good with the install so I rebooted and got the same error. No bootable drives.
I continued this for another couple install attempts using both installers and had no luck.
It was the alternate installer that tipped me off. I kept getting a warning that grub failed. So I installed via the main installer and then grabbed a super grub disk and dd'd it to another USB drive.
Super grub was unable to detect any grub installation. So no wonder it won't boot! Using rescutux I attempted to repair/reinstall grub but it just errored and chroot didn't work either.
