I used Boot Camp to put Windows on my Mac. I got worried incase it would wipe Mountain Lion off my Mac so I cancelled it. I deleted the partition.
Now everytime I start my Mac up, it tries to open via Windows (which isn't installed).
How do I make it automatically boot up using Mountain Lion (10.8.2)?
iMac, OS X Mountain Lion (10.8.2)
To start into OS X, press X key while your Mac is starting. You can also press Option key and select Macintosh HD.
Then, to start always into OS X, open System Preferences > Startup Disk, and choose Macintosh HD.
You don't have to worry about the Windows installation because if you don't do anything wrong, Windows and OS X will share space on the hard disk of your computer. If you want to install Windows with Boot Camp, print this file > http://manuals.info.apple.com/en_US/boot_camp_install-setup_10.7.pdf
There's only Macintosh HD in System Preferences > Startup Disk. How can I delete Windows if it's not there?
That means that you don't have Windows installed. Just choose Macintosh HD and everything will be back to normal when you start the computer
It still automatically tries to start Windows and it says something like 'insert a bootable device'
Reset the PRAM. It will restore the startup disk, so after doing it, go to System Preferences > Startup Disk, and choose Macintosh HD
Thank you very very very much! I thought my problem was un-solvable. Thanks for your time and patience, and for solving my dilemma.
You are welcome
How do I select my Mac to start up on Mountain Lion rather than Windows?
