I searched for a similar question and I found this although that one is talking about a Windows 8 Preview version. I recently bought a Windows 8 PRO license and I was given a link to download it. After I download that exe file (around 6MB) it ask if I want to install in the system, create a media or just the ISO. I tried to create the media from several computers and when I try to install it in the computer via USB (I don't have DVD), it always says that there are some missing drivers.

Any ideas how can I create a bootable USB installer for Windows 8 PRO?

I don't remember all the specs from my computer but I know it has an Intel Core 2 4400 2GHz, 4GB RAM, NVidia graphics, There's no other PCI connected to the motherboard.

It's worth mentioning that I had Windows 8 PRO installed in that computer before, but it suddenly stopped working and that's why I want to reinstall it again. Last time the same thing happened with the drivers but I have no idea why after a while it skipped itself the missing drivers part (I tried leaving now the computer on that screen again but no luck).

The process your using is the suggested way to create a bootable USB image of the installer. – Ramhound Dec 17 '12 at 12:36
    
@Ramhound I know, but because I keep on getting that error I was wondering if I can do it in any other way just to try. "Downvoter" please leave a comment about your vote. I'll appreciate it. – SERPRO Dec 17 '12 at 13:59
    
The problem stims from the iso being corrupt. Are you pausing the download or something? – Ramhound Dec 17 '12 at 14:12
    
@Ramhound no.. and I have a quite fast broadband (30Mbps). And it happened the same when I used a friend's computer to download it. – SERPRO Dec 17 '12 at 14:34
    
So you had Win8 Pro installed before, it stopped working and you bough a fresh copy to reinstall? Why don't you simply Reset your PC from the Advanced Startup Options? – Karan Dec 17 '12 at 19:29

You can download the ISO and then use Microsoft's Windows 7 USB/DVD download tool to "burn" it to a USB drive.

Thanks, I'll try that later and then I'll check the ISO file with this : answers.microsoft.com/en-us/windows/forum/… – SERPRO Dec 17 '12 at 14:36

I think the problem was with the USB stick. I downloaded again the installer from Microsoft, installed in 2 different USB sticks, and the other keep on having the same Driver's problem, but the second USB stick I tried worked with no issues.

Right. I had the very same issue, and I solved by installing from DVD rather than from USB. – Claudio Jan 14 at 8:16

Just download the ISO of the Pro version of Windows 8 and use your key to activate it.

Please provide some additional information about your PC.

Thanks from your answer @Sanny-sin If I download the iso, how can I put in the USB memory to boot from it? is there any tool for that? – SERPRO Dec 17 '12 at 14:01
    
@SERPRO - The Upgrade Assistant is the tool you should be using. If you want an alternative the Windows 7 tool also works with any Windows 8 iso. – Ramhound Dec 17 '12 at 14:10
