I have saved the sectors and applied delete/undelete to the lost Win7 partition. The result of both is shown in the Attachments.

Since Undelete found the new 100 MB boot partition and in addition two older unbuntu partitions but not the the pre-existing Windows 7 partition, I am in a different situation than your working assumption stipulated here:

Should I apply your above advice in an analogous manner i.e. deleting 100MB Windows boot partition as well as the two ubuntu partitions selecting the
option to clear the boot sector and then try undelete again before restoring the backup copy of the Win7 boot sector? What about the two Extended partitions containing the ubuntus?

I have an additional question that may have had implications on the result of the undelete:
When selecting "Undelete" I was asked
"Start on Cylinder 2 ?"
Since I did not know the implications and "Yes" was selected as default, I pressed "Yes". Was this action correct?
