I have tried to do a single install on a laptop that previously hold Windows 7. I tried to install 64bit desktop version of 14.10, 14.04, and now 13.10 with the same results. Installation from USB works just fine. No errors during installation, but after reboot it just wouldn't start from the Ubuntu partition.
The processor is intel core i5-2410M cpu @ 2.30 Ghz x 4
EDIT from comments: I tried to run a boot-repair and it answers "GPT detected, please create a BIOS-Boot partition..
