I have an Laptop with an Aptio-BIOS and OEM Windows 8. My Harddrive is defect but warranty expired. So I bought a new Harddrive, built it in and now I´m trying to install Windows 8 from an original Windows 8 Setup-Disc. Every time I start the Laptop the BIOS-setup comes up. Now I achieved the boot menu, but the only Boot option is

UEFI: IP4 Realtek Ethernet Controller

How can I boot from the Setup-Disc?

EDIT: After activating CSM the setup still comes up and I´m still unable to boot from cd.

See if there's an option to turn off secure boot. If that doesn't help, see if you can enable the "legacy BIOS" or "Compatibility Support Module (CSM)". –  Karan Mar 7 '13 at 1:49

Just got a "new" Notebook (selled here in Austria by "Hofer") and came to know that the BIOS changed and is different from previous ones: less possibilities to change and in the boot order option also only UEFI: IP4 Realtek UEFI: IP6 Realtek to choose from.

In the same menu the is a select box: "boot from windows8" which is activated

after chanaging this selection to "other system" and saving/reboot I was able to get into the F7 select boot device (F7 or F9 what ever suites your notebook) and start from DVD or harddisk. Selecting harddisk to boot from I was astonished: no windows 8 coming up so I had to go back to BIOS again and change back to "Boot from windows8"

Hope it helps, Fritz

You should disable "fastboot mode" and restart before being able to see "Boot device priority"/"Boot override" : you should then see boot priority options

If you find other problems booting try setting "secure boot mode" to CMS

Welcome to Super User! Generally we like answers on the site to be able to stand on their own - Links are great, but if that link ever breaks the answer should have enough information to still be helpful. Please consider editing your answer to include more detail. See the FAQ for more info. –  slm Apr 15 '13 at 14:02
