cim and im Linux NTFS imaging scripts v1.1.1 README
Using cim and im is very easy:
1 - Down the .iso then burn to CD or use YUMI or unetbootin to boot it off a USB drive instead
2 - Boot off the SystemrescueCD + cim CD or USB device you just created
3 - When you get to the prompt, type 'cim' to create images and 'im' to restore. Just typing the script names with no options will print full instructions to the screen complete with examples.
Whats more tricky is using the Windows Automated Installation Kit and sysprep to prepare Windows 7 installs for successful imaging but there is a good guide to that here:
Follow that guide through to step 13 then in step 14 you can boot SRCD+cim and run cim instead. You can safely ignore any references it makes to using or creating a WinPE disc as in that guide they are simply using it to create the image.
It is also vital that your Windows 7 install is contained within a single partition - the first on the primary storage device, if you want to image it using cim and im. This will likely be the case for people who have upgraded to 7 from Vista or XP but otherwise it is more likely your Windows 7 has a hidden boot/recovery partition. In this situation you have to either use fsarchiver manually, use Clonezilla instead or wipe your partition layout, create a new one and then install 7 afresh within a suitable cim-friendly partition map.
