so i wnet to bios and selected to boot of my USB but it tells me it isnt bootable and whenever i try to install the windows 7 off of my usb it tells me i need at least 800MB of free space but i have a empty 2TB HDD a SSD with over 480GB of free space and even the damn USB has 28GB of free space so i dont understand why the windows setup shows me this error message......
I'm confused, if the USB is not bootable how are you installing Windows from it? If it's not booting off the USB drive how are you trying to start the Windows 7 setup? Does not sound like you are doing the setup in the right way. Did you just copy the disk files to the USB drive? If you make the boot disk correctly on the USB you will not be seeing 28 gb of free space since it will create a much smaller partition to use and the rest will be unalocated and unformatted space.
First thing, make a correct USB setup disk that boots, if you have a Windows 7 disk, make an ISO of it on your computer, then using the Microsoft ISO to USB utility make a bootable USB stick. Or just use the original DVD if you have an optical drive.
