I have the 32-bit ISO of the Windows 8 Consumer Preview and I burned it to a DVD (using Nero Express on Windows XP) to install in VirtualBox on my other computer (running Fedora 15).

The problem is, when I try to boot from the ISO in VirtualBox on my Linux computer it gives and error and won't boot.

Interestingly, when I open the ISO in Fedora's Archive Manager, it shows it as occupying 2.5GB, but only containing a blank text file called README.TXT; however, when I open it using 7zip on Windows it shows it as having quite a lot of files.

Why is the data differing between platforms? And if the ISO isn't corrupted, why isn't it booting?

EDIT: BTW, the error I get when I try to boot in VirtualBox is the same as this one

EDIT #2: Turns out Windows 8 requires NX; once I enabled it it booted just fine.

Did you read the README.TXT? I think I can guess what's going on, and if I'm correct, I'm nearly 100% sure the ReadMe also tells you what's going on. :P –  Mehrdad Mar 3 '12 at 4:03
    
@Mehrdad README.TXT is completely blank –  Nate Koppenhaver Mar 3 '12 at 4:15
    
> Why is the data differing between platforms? And if the ISO isn't corrupted, why isn't it booting? Use a tool like IsoBuster or ImgBurn to get more detailed information about the ISO. With IsoBuster, you can view the file-systems (and the files they contain) that are present in the image which will more thank likely explain what is happening: different tools look at/see the image differently. –  Synetech Mar 3 '12 at 6:00

You have two separate issues that have nothing to do with each other.

Your installation problem most likely has to do with you using a virtualization product that doesn't support Windows 8 because of the version or the way it's configured. You don't mention your CPU, but VT-x technology is required to support Windows 8 on VirtualBox. If you disabled it in the BIOS or your CPU doesn't support it, that's your problem. Make sure to select Windows 7 as the machine type and give it at least 1GB of RAM. Use VDI, enable APIC, enable PAE/NX, enable VT-x and nested paging. Then it should install.

Your other issue (some tools showing the files on the DVD and some not) is just lack of support for UDF on older tools. It doesn't indicate anything wrong with the disk.

Thanks; my CPU does support VT-x, and it is enabled in the BIOS; I had issues with that not being enabled before so I always check that. See the EDIT #2; it was NX not being enabled that was preventing it from booting. However, I know that UDF works with the tools that I have; because I needed to open a UDF disk before and it worked just fine –  Nate Koppenhaver Mar 3 '12 at 4:18

Turns out it was Fedora's Archive Manager causing the problem, I opened the ISO using PeaZip and it showed all the files.

I still don't know why that particular ISO was not opening right with the Archive Manager; I'm pretty sure I was able to open other ISOs with it before
