Hi,
I got a new pc and i now i just have to install windows the problem is when i boot the pc up it says disk boot failure please enter system disk and press enter.So i put the windows disc in and press enter and then it goes to a black screen with the same disk boot failure please enter system disk and press enter.So how do i get windows on.

Go into the BIOS and check out the BOOT sequence. Make sure that Boot from CD is enabled as well as enabling boot other devices. Then when you restart your PC you should get the option to boot from CD on the startup screen by pressing any key.
