Turns out my flashdrive was bootable regardless of USB/DVD download tool giving me an error saying it was unbootable. Have no idea of why, but I read it was because the drive was ALREADY bootable. Installing W7 on my laptop as we speak. I am a happy camper!
So I'm trying to install W7 onto my Asus laptop from a flashdrive. The laptop came with W7 installed but I had to wipe it for a number of reasons. I'm not in possession of a W7 disk so I installed Vista temporarily since I was in possession of that disk as my desktop runs it. I dislike Vista and my laptop doesnt have internet because of it so I want to go back to W7.
I downloaded a Windows 7 Professional 64bit iso from here http://answers.microsoft.com/en-us/windows/forum/window... (it was the only place I could find this version without a service 1 pack), I never "officially purchased" W7, I had it preinstalled in my laptop and the sticker on the back has the key for it so I figured I'd just use that.
I followed these steps for creating a bootable flashdrive http://www.wikihow.com/Create-a-Bootable-Windows-7-or-V... the only thing I did different was use Rufus http://rufus.akeo.ie/ instead of the USB/DVD download tool because when I used it it told me it copied the files but couldn't make the flashdrive bootable. Rufus worked fine and did not give me any warning messages.
I followed all the steps accordingly; but when I get to the BIOS screen on my laptop to boot from the flashdrive, the boot tab does not give me the option of booting from a removeable disk. It looks like this:
UEFI Boot [disabled]
PXE ROM [disabled]
Download a new Windows 7 image of the same version that you use from HERE and download and use the MS USB installer tool and read the directions from HERE using the downloaded Windows 7 image. After installation, activate with your key.
