  2. How To Choose Mac Os On Boot Camp Mac

Hi Jkutos,

I understand you are not able to boot to your Mac since installing Windows 7 with Bootcamp. If you are seeing a prohibitory symbol, your Mac can't find a valid System Folder to start from. You will need to reinstall the OS X to resolve the issue. Do you not have a Time Machine backup of your computer?

When you see a circle with a slash symbol instead of the Apple logo, it means your Mac couldn't find a valid System Folder to start up from.

Jul 14, 2006 Glad to hear that you’re having a good experience with Boot Camp.It’s pretty cool, as I explain here: Running Windows XP on your Mac with Boot Camp. I too noticed the same issue, however, and there’s a bit of a trick to getting it to boot into Mac OS X each time, rather than Windows. Jul 11, 2014  All you need to do to boot straight into OS X is press and hold the “Option” button on your Mac’s keyboard as soon as you power the system on. Keep holding it.

If you're using your Mac at a school or business, it might be trying to start from the wrong version of OS X. Contact your IT department for more help.

If this is your personal Mac, try reinstalling OS X by using OS X Recovery.


How

Mac reboot boot camp. OS X Recovery includes a built in set of utilities as part of the Recovery System. You can use OS X Recovery to do the following:

  • Restore your Mac from a Time Machine backup.
  • Verify and repair connected drives using Disk Utility.
  • Check your Internet connection or get help online using Safari.
  • Install or reinstall OS X.

To start your computer from Recovery, restart your Mac and hold down the Command and R keys at startup.

Hold these keys until the Apple logo appears. After your computer finishes starting up, you should see a desktop with an OS X menu bar and an OS X Utilities window with the options listed above. If you see a login window or your own desktop instead of the Utilities window, it's possible that you didn't press Command-R early enough. Restart your computer and try again.

Choose the option you want to use from the Utilities window or the Utilities menu.

In order to reinstall OS X, you need to be connected to the Internet using Ethernet or Wi-Fi. If you're using a wireless Internet connection, click the Wi-Fi menu in the upper-right corner of the screen to select a nearby Wi-Fi network. Choose your preferred network name and enter a username and password to join the network if needed.


Take care,

Once you've set up Boot Camp, you have three different ways to make the switch between partitions. Let's look at these based on their starting points.

If you're in Windows, you can switch to the Mac OS X partition using the Boot Camp icon in the System Tray. Click the gray diamond-shaped icon, and click 'Restart in Mac OS' from the pop-up menu. Then, confirm your choice to reboot to Mac OS X and give the computer about a minute to make the switch.

If you're in Mac OS X, you can switch to the Windows partition using the Startup Disk utility within System Preferences. In the Startup Disk, choose the 'Windows on BOOTCAMP' partition, and click 'Restart.' Then, confirm your choice to reboot to Windows and give the computer about a minute to make the switch.

If the Mac was powered off, you can choose which partition to boot before the Mac selects for you. To do this, press the Option key on the Mac while it's on the blank white boot screen. Within a couple of seconds, the Mac should present the two partitions to you on the screen. Use the arrow keys to select a partition, and press Enter to boot to it. This Option key feature is available either when booting from a powered-off state or if you're rebooting from Windows.
