I am trying to install Windows 7 side by side with Ubuntu. The computer is already running Ubuntu and I have partitioned the hard drive formatted it for NTFS and have a USB copy of the .iso of Windows 7. The usb is also formatted for NTFS and contains the .iso of Windows. People are telling me that I need to boot my computer from the USB via Grub.But I have no idea how to use Grub. So I need to know what commands to enter into Grub once I have it to boot the computer from the USB? How to install Windows 7 once I have booted off the USB into the blank partition? My computer is also fairly old so a lot of the recent keyboard commands don't work.
There has to be an easier way to do this. What is that? What commands to enter into Grub to boot my computer off a USB? How to install Windows 7 via USB to a separate partition of my hard drive?
