Bootable Flash Drive or Hard drive to install Windows 7

Original Title: Estimating Windows 7 WIM File sizes - UFD too small for image

I was trying to capture awim file for Windows 7 to a bootable ufd, but the 16GB UFD was too small.  I reran and directed the capture to a USB hard drive.  Is there a tool to estimate the UFD size required?  Is the FAT32 format a constraint?

Can I build a bootable USB hard drive and capture the image to it so that If I boot from the USB HD instead of the UFD?

Can I install from a USB hard drive instead of the UFD?  Then I would not be limited to the USB size of 16GB or 32GB.

Hi Dan Hauge,

You can use a Hard Drive, if you wish to, instead of a Flash Drive to make a bootable drive. Also, file system on the drive is not a constraint here. You can make a bootable flash drive even if it is a FAT32 file system.
