Hello there! I'm completely new to linux; I've used ubuntu and other distributions but just at user level.
The problem is, I've got a Sony laptop with the inside H2O (3.9) BIOS, don't have the complete specs right now, but i can check them when i'm back at home. It has a NVIDIA 640M LE, 8gb ram, an Intel Core I7 processor, and a 750gb HD.
The screen, although working well enough, is broken, some plastic parts are broken also and it's not in good condition overall. It worked well in every aspect aside from those.
As i have a desktop, computer to work already, I don't need the laptop for working anymore, so I thought it could be a good idea to use it as an entertainment center in the living room, you know, for watching movies, playing some old-school games in local coop with and without emulators and so on.
I thought the still in beta SteamOS (Think it's a Debian-based distro) could be a nice option, so I've installed it. The installation process ran without issues till the first reboot; after that i only get "operating system not found" error and nothing else.
I unplugged the HD and made a complete installation from scrap with every reboot needed in my desktop computer and everything worked out fine: installing games, browsing the web, playing music, etc.
But, after plugging again the HD with the OS installed in the laptop I still get the same error; operating system not found.
Any ideas of how to solve it? Thank you in advance, and sorry about my english
