Restoring all files from a .dmg

Hello all. I have an iMac 27 inch running Snow leopard. About 5 weeks ago I had a problem where the system would not re-boot. I went online to try to solve it but eventually took it back to where I bought it (Future Shop). It was still under factory warranty luckily.

They ended up restoring the iMac to factory conditions. Stupidly, I did not have a Time Machine back up or any other except that I was able to save all my files as a disc image.

Luckily I was able to mount the image so I did not lose any data.

My question is what is the best way to restore all my preferences, applications, System, Library etc. I know I can't just copy over and replace all of theses files and folders.

Has anyone ever had this issue and does anybody have some advice on how to proceed.

Thanks very much.

Have I posted in the wrong area?

Just wondering? Does anybody have any ideas on this or where I can go to learn more? Thanks.

The area you're posting in is OK. To answer your question, if you did not backup all those settings and preferences with Time Machine or a cloning program, they're gone.

If you wish to learn more about Time Machine and backups in general, go to this LINK.

Thank you. The thing is, I did save everything with the dmg back up. I saved the entire hard drive.

Saved it how? On an external drive? If so drag to the desktop and double click to pen the file up and see what is there.
