Installing Windows 7 on MacBook Air? Last night I was trying to install Windows 7 on my new MacBook Air, I started it and the Windows installation began. I deleted 80GB HD (preinstalled Mac OS) also deleted, but I could install windows completely. Now my MacBook is not starting or booting from external USB DVD rom, please help me out, not even booting from the original Mac CD which came with PC.
Create an image file from install DVD using Disk Utility. Restore this image to a USB flash drive. Then start the Macbook, press and hold "option" button. you will see the start up options. Select USB drive and complete installation.
