Restoring a damaged Windows.old folder?

Suffered a head crash on a laptop's C: drive. Was able to recover nearly all the data using Linux tools, but the boot sector and some critical Win 7 files were damaged beyond recovery, so I have been unable to create a bootable volume using that info. I cloned the data to a new physical volume and did a fresh Win 7 Ultimate 64 install over it (same as the original volume). Updated to SP1 to match the original volume. But there are still corrupted files in the Windows.old folder which, if copied to the new install, will prevent it from booting. Can anyone help guide me through restoring my old user accounts and application preferences to the new install? No restore points to go back to, unfortunately, due to the crash.
