So I have an ISo that I bought from Microsoft and I put it on a USB but my pc can't boot from it for some reason so now my only option is to burn it to a disk but I have 2 disks and there both only 700mb, so is there any way to remove some unimportant files off the iso like language packs so I can burn it? Or is there any way to put half the install files on one disk and half on the other and do a " insert disk 2 " kind of thing? Thanks in advance, and any answer is appreciated even if it is a simple yes or no lol.

Don't use the Win7 USB Tool or whatever that thing is called. Use diskpart to prepare a USB drive to install Win8.

Insert flash drive and open up command prompt (run as administrator)
Type in the following
diskpart
list disk
select disk
clean
create partition primary
select partition 1
format fs=ntfs quick
assign letter (any letter that's not in use)
active
exit diskpart
Still in command prompt, navigate to your Windows 8 ISO file, you may have to mount it first
If the mounted drive is letter F then we need to navigate to the F:\ in command prompt
From F:\ in command prompt, type CD boot
F:\Boot> then type bootsect /nt60 X:
X= letter you assign to your flash drive.
If it's done successfully, it will say bootcode successfully updated...

Yes I used the Windows 7 USB/DVD tool and it worked fine and all my bios boot settings were fine but every time it tried to boot off the flash drive it says windows did not start successfully, would you like to start windows normally? Yes or no. That's what it says every time

exit command prompt.

Now copy everything from the Windows 8 ISO into the flash drive.
Restart system and boot from flash drive to being installation.

At that point your USB media is mounted as a drive letter, you should be able to simply copy and paste the files from inside the ISO to the USB drive as you would copy files to a USB storage device. If you have PowerISO, yes, you can copy them from inside the ISO when mounted.

Another possibility which might explain why your media created with the Windows 7 USB/DVD Download tool was failing could be if the USB drive was connected to a USB 3.0 port. The Windows 7 USB/DVD Download tool breaks support for USB 3.0, but the media should work fine if connected to a USB 2.0 port.

The bootsect portion should not be necessary. You should be fine with just formatting the drive, setting the partition as active, and copying the contents of the ISO to the drive as this includes the boot files of the installation media.

And it failed. Here's what it says," a bootable device has not been detected. Please refer to the product guide at intel.com/support/motherboards" so what now? I tried using a different usb port and it still didn't work. And yes all the ports on this pc have usb 2.0. I think that it just isn't recognizing a removable drive when it starts up. But the light on the flash drive blinks. I am so confused. : \
