So, I'm new to Linux. I want obedient computers, and I already use mostly open-source software on Windows as-is (Keepass, Firefox, Thunderbird, LibreOffice, etc - I'm cheap, what can I say). The whole NSA thing has really creeped me out of the idea of using non-free operating systems for much longer, so I'm giving Ubuntu a try.
I'm trying to install it on a Fujitsu Lifebook P1510D - an older swivel-tablet type design, very small, with a Pentium M ULV 1.2 GHz processor, 1 GB of RAM, and a 30 GB IDE hard drive. I figure it's a perfect old machine to pair with a fresh install of the latest Ubuntu, but I am having no luck whatsoever. I've tried installing both Ubuntu 12.04 LTS AND Ubuntu 13.10, and both seem to get through the installation process just fine (and, in fact, booting the Live CD shows the hard drive partitioned with files copied to it) - yet when they reboot and try to boot the OS natively from the hard drive, I get the same error:
"Operating System not found."
I have not tried to install Windows, I suppose I could give it a shot, but what on Earth could be causing this? I've even tried the boot-repair option, and I checked my flags in GParted. Help me, Ubuntu Forums, you're my only hope.
