I'm working in Windows 7 and trying to create a bootable Windows 7 partition. I'm working with a computer with no optical drive and the only USB device I have is a 2TB external HDD with a bunch of data. It has 2 partitions, the first is NTFS with my data, and the second is empty and 20GB large. I've tried formatting the 20GB partition as FAT32 and marking it active, but UNetbootin and Windows 7 USB/DVD download tool cannot seem to find the partition.
I don't want to move all my data. Is only the first partition eligible to boot? Can I make the bigger partition with all my data have the Window 7 boot data without moving all my files? Is there a way to make the second partition bootable?
