I bought a new PC (i know that it is better to build pc yourself but there was very good pc for low price. And it came with Linux. You can browse the internet and download Steam and play but not all library so i thought i will install Windows 7. I got Windows. Put it in. I go in to the bios put it to 1st read disc and then read hdd. So i saved and reset PC. And it didnt showed to press anything he just thinks and starts Linux. Tried one more time and nothing. Thanks for help.
