I have a similar problem, but didn't quite understand the solution...
time machine/capsule backs up my macbook. Just got an imac, and copied the image to it. Didn't realize it REALLY copied the image to it... so Time Machine decided the new imac
was the macbook.
No. Time Machine always knows which Mac is which, via an identifier that's embedded in the hardware on the logic board.
But it did copy the +Computer Name,+ which you can change via +System Preferences > Sharing.+
And it did copy the Time Machine preferences file (with the backup location you specified), so it backed-the new Mac up to the same destination.
Now Time Capsule backs up the imac... but not the macbook anymore.
There is still a 425GB sparsebundle for the old macbook on the Time Capsule...
Depending on how you answered this prompt, there may be
two sparse bundles:

See #B5 in
Time Machine - Troubleshooting (or use the link in *User Tips* at the top of this forum), for details.
If you said +Create New Backup,+ there should be
two sparse bundles, one for each Mac.
If you said +Reuse Backup,+ there should be one, containing the backups from both, and as it says, the MacBook can no longer use the same set of backups.
Question: Is there a way to reattach to that sparsebundle for backing up the macbook or do I have to start all over?
Probably. First confirm whether there's one sparse bundle or two, and roughly how many backups of the iMac you've done.
