How do I format my flash drive to FAT16 to make it bootable?
I formatted my flash drive to FAT32 but when I plug it into my newly built computer, it doesn't boot from it. I have tried all USB boot options from FDD to everything else that I can't think of. My guess is that I have to have FAT16. I have read many answers, and they say something about you can only have a flash drive up to 2Gb or 4Gb. I have an 8Gb flash drive. Can I still format it to FAT16? The Windows 7 I have on it is I think either 2-3Gbs.

No, you can use either FAT-16 or FAT-32. What you need is an operating system on the flash drive from which to boot.
Download and install the HP USB disk format tool, SP27608.exe.
Download the MS-DOS files IO.SYS, MSDOS.SYS, and COMMAND.COM to a convenient folder.
Run the HP format utility and select FAT format. Choose "Create a DOS startup disk", then browse the folder containing the MS-DOS files and click OK. Proceed with the format. When done, the drive should be bootable.
