Installing windows 7 on mac

Try to start your mac while holding the c key, it should boot to ur windows dvd and start the installation guide, you should if you come so far to format the bootcamp drive to NTFS and your ready to go.
If all that is not working its because the version of your windows dvd isent bootable and you gonne need to get yourself a full version.
Bootcamp supports for now windows 7 even though 8 is possible but not fully supported.

Good luck.

der findes ikke en 'free version' af windows.

I have tried to hold the c key and nothing happens. i hold it when my mac restarts.

So hold the Alt key down when start and choose the windows dvd to boot from.
