Lenovo bios key taste FN+F12 - enter the cd boot, select dvd-rom then enter for boot?

WHen you buy Lenove you should know before instal windows xp, 7, 8

1. To enter bios key taste FN+F12
2. Enter the cd/dvd-boot
3. Select from dvd-rom then enter for boot: (maybe you will get 2 version of dvd, the second one is protected). Select first option of DVD then enter, after restart automatic will boot from CD/DVD

So, it is not like other computers, to select, then enter, the change the boot, then save and exit.

Bios is just for Boot.

simple select (up and down), and when decided where to boot, press "enter" and will automatic restart and enter to boot to the drive you selected.
