Reverting To a Backup

I uninstalled some software improperly and now it won't work, so I want to go back to my backup on my external. Is this how? I use super duper.

"Other Notes
My reccomendation is to use Carbon Copy Cloner if you have the space. This will make a copy of your current system and you can save it as a diskimage that you can revert back to if you have problems after the installation. To do this, start up from the install disk and under Disk Utility you can select to reformat a drive using a disk image."

Start up from your external drive and launch Superduper. Backup your external drive to your internal drive. Done.

To boot from an external drive, restart your Mac and hold down the option key (sometimes labeled "alt").

Thats what I thought too. But when I do it I get a weird folder logo with a ? on it.

Well the other alternative is to boot off the DVDs that came with your Macbook, select 'Tools> Disk Utility' and then restore your internal drive volume from the external drive.

But it sounds as though your external volume is HFS+ formatted, but with the wrong type of partition scheme. (It needs to use GUID).

Thats weird, when I backed it up with superduper I never had a problem. And I used disk utility to format it. Is there somewhere I can check to see if it is GUID, or change it to that?

Sure, just fire up Disk utility, select your external drive and it'll show you the partition scheme at the bottom of the window.

It says "Apple Partition Scheme" is this correct?

SuperDuper has been a pain in the **** for me. I like to use FileSalvage.

Nah, for intel Macs it needs to be GUID Partition table.
Apple partition table is for PowerPC Macs.

You'll be able to read it fine, but it won't be bootable.
