You will recall that a Ghost 15 Copy Drive with Win7 leads to failure of both HDs to boot. It is related to both BCDs being made invalid by the clone process and the Disk Signature not being copied to the new HD. The following method of Copy Drive results in both HDs booting into Win7.
See this web page on how to do a BCD Edit from BING.

Four parameters are edited. The first two result in HD 0 and Partition name. The second two result in {boot}. Well, if you make all four result in {boot} prior to performing Copy Drive, it will succeed.
Hopefully, a Symantec fix for Ghost 15 isn't too far away and we won't have to do pre cloning BCD Edits.
Edit..... I should mention, following a Win7 install, all four BCD Edit parameters are HD 0, Partition name. It is a little more complex if you have a SRP.
