My MacBook Pro only boots up with Windows 7

Question

I've installed Windows 7 on my Mac with Boot Camp and I had Dual Boot on my screen when I want to select to chose Operating Systems. Yesterday, when I turned on My MacBook Pro (MD 322) it boots up with Windows 7 automatically. I think my OS X installation is damaged and I can't check the OS X partition in Windows.

What can I do?

Solution

Open the control panel and in the search box in the upper right, type boot camp. You should see the Boot Camp disk drive icon below. Open it and it let you change your boot partition.

I could not find something similar in my control panel.

@MohammadHasanEsfahanian - This means you didn't install Windows through boot camp. Which means your OS X installation is gone. Which means you will have to install it again.
