Booting from DVD issue, "Reboot and select proper boot device".

Hi! I just burned a copy of the Windows 8 Developer Preview onto a DVD. I have created a partition for the new OS (because I don't want to install over Windows 7).

When Windows 7 is running and I pop in the DVD, the computer directly recognizes it as a runnable program. I'm also able to install Windows 8 when Windows is running.

But because I want to install it to another partition I need to boot from the DVD. But I can't. First it just ignores the DVD, and boots right into Windows 7. So I tried to force boot via BIOS. Then it just said "Reboot and select proper boot device or insert boot media in selected". Can someone please help me?


I have an ASUS N82J laptop, 4GB RAM, Nvidia GT335M, i3-350M processor, 500GB HDD.

Thank you in advance

im thinking it ignores the disc because the order you have for booting 7 is from hardrive first, if you press f1 or f8 or one of the f buttons at the black screen before 7 loads you will get the order of which to boot from first ,select disc and it should load the install screens .

Forgot to mention that booting from the DVD-drive is set to number 1 in booting order. Still doesn't see the DVD while starting :/
Thank you for the quick answer though

ok ,thats a tricky one then,
as for the quick reply i copied it from my reply over on sevenforums

Is the disk actually bootable? Your statement here would seem to confirm this as the problem.

Have you checked with a known bootable disk, such as a copy of XP, Vista, or Windows 7?

How did you burn the .iso image of WDP to disk?

Haven't tested with another DVD. Will do

Umm, like I always do. Open with WinRAR, and then copy over to the DVD. I know that sounds weird, but it has always worked perfectly fine when booting through DVD:s. Maybe I should try with a real DVD-burner just to be on the safe side xD

That's the reason. I take it that you have extracted the contents of the .iso file and then copied the extracted contents to disk, correct?

Yes, exactly.

That method works if you are making a USB installation stick, but as part of the preparation you have to make the stick active, i.e. bootable. With a CD/DVD, the only way of making it bootable is to burn the .iso image directly without extracting its contents first. A suitable program for this purpose is ImgBurn, available from The Official ImgBurn Website
