if you are going to create a master image, you should probably go into the custom disk configuration in windows and choose to make the partition smaller than max disk size.
For example, Iβm creating the master image for Windows 7 Pro on a new workstation that has a 1TB HDD, but I may need to deploy it to a bunch of workstations that have between 160GB and 1TB HDD. During the windows setup, choose the advanced options for disk setup, and make the window partition 80GB to 160GB depending on your needs. Leave the rest of the 1TB HDD unpartitioned (other than the special Win7 partition that it makes automatically).
If you do this, then you wonβt have a problem choosing the Multiple Partition - Single Disk image type option in FOG and deploying to a variety of disks.
Another option, is to use GPARTED on a USB bootable flash drive, and reducing the size of the windows partition down before you take the master image. GPARTED should let you shrink the partition down without corrupting windows. Make sure to leave enough free space for Windows to operate, which I think is about 10% (so if you used 30GB for the install, donβt shrink below 33GB).
