...but rather than re-installing the OS ( W7 Ultimate ) and all software can I not simply make an image and copy it to the SSD, thereafter modifying the BIOS to boot from the SSD rather than the original HDD leaving the latter available for data only ? I gather I have to disable Prefetch, Super Prefetch and disk defragmentation, does anything else need modifying ? Thanks in advance for any help. P.S. I use PING to create/restore images and have done several restores without problems.
