Hello,

Try this 1

Place the Windows 7 DVD and then make sure that the first boot device is set

to your DVD-Drive in CMOS settings to boot from it.

For basic information, click on the below hyperlink "Boot Order" and follow the

instructions given under "How to configure the computer BIOS settings to

boot from CD"

Boot Order

If you want to continue using Windows 8 then try updating the drivers.

Good Luck

Oh !!
Thanks Jack4rall.

But it is the simple instruction to do. My problem is that when i have entered the CD it says no windows found. But CD is okay.
