No driver install with Boot Camp Assistent possible

I copied mit Win7 bootcamp partition with Winclone 7.1.3 standard to an image file. No problems so far.
Then I switched to my new MacBook and created a partition (80GB, GUID…). Then I restored the image file to the partition. The file system was changed to NTFS and no errors occurred.
Then I tried to follow you instructions and started the Boot Camp Assistent to update the drivers of the new partition. But the Boot Camp Assistent doesn’t recognise the new partition.

if Windows doesn’t start up due to drivers issues, try this:
