You can use free tool from Microsoft "Windows 7 USB DVD Download Tool". This tool will work fine with win8 iso images. Only 4 steps to create bootable USB drive: Select ISO, Select drive (USB or DVD), Format drive and Create.
can upload the links becoz it says i have to complete 20 posts. but if u want u can google it with then given names. and i tried microsoft usb tool but not working on 64bit iso, this is the only step it worked with.
The only thing I did was, take my Sandisk 8GB flash drive, reformat it to FAT32, take the WDP disc image, open it with 7-zip, extract the contents of it on the root of my flash drive, rebooted, profit. No 3rd party software or anything (well, not counting 7-zip, but you could use any other extractor like WinZip and WinRAR)
Or this Start CMD(as administrator) in Windows 7 or vista Code: diskpart.exe list disk (locate usb drive) select disk x(x=usb disk no.) clean create partition primary select partition 1 active format fs=ntfs quick Extract contents of iso using WinRAR into the USB drive. Boot from usb and install.
Why not using Windows 7 USB DVD Download Tool? Another simple solution would be to format as NTFS, copy the files and execute {Drive}:\Boot\bootsect.exe /nt60 {Drive}: /force
This method is the best, you can also use "format fs=fat32 quick" instead once you have no files bigger than 4gb The reason i like this is that after you use the flash drive, just delete the files from it (don't format) and you can always copy the installation files from any W7/W8 iso to it again and boot without going through the above steps again!
You can also use RMPrepUSB (see website) - it also has a tutorial on how to install Win8 onto a USB drive and boot Win 8 straight from USB.
