You'll need your recovery discs that came with your computer, then it should be fine. Insert the disk, boot with C held down, select Disk Utility from the menu utility after selecting the installation language, format the drive - Mac OS Extended, GUID partition table and then select to restore from TM.
I wish you the best of luck ![]()
I installed ML on my iMac and have serious problems since. I want to go back to Lion. I've been using TimeMachine to backup on an external disk. If I restore to the day before I installed ML, will Lion be reinstalled too - i.e. the iMac will be exactly as it was before installing ML?
And if so, should I start up using comm+R then restore from TimeMachine
