I've been at this for hours and have looked through tons of forum posts without finding anything quite matching my situation.

I started off trying to follow these instructions:

including using Ubuntu 12.10, disabling quick boot, and disabling secure boot.

The installer couldn't detect what space was used or not in the Windows partition (and gparted sort of just freaked out when I tried it), so I used Partition Wizard in Windows to shrink that partition. After that the installer (from USB) gave me the option to install alongside the other OS(es, it thought there were multiple) and it correctly used the large, unformatted one left over from the shrink.

After that, on restart the manufacturer logo shows for a split second before I get a black screen with "Operating system not found." I can get into the BIOS/EFI and boot from USB, but even the EFI's option for loading Windows just results in the "Operating system not found" screen.

I tried boot repair twice as the instructions said. The link that it gives is here: The result is still the same.

So basically, I can't access Windows or Linux, I can only boot from USB stick. This is on a Sony Vaio S series. Any help would be greatly appreciated.
