    Ok, thanks in advanced but I have a MacBook that is using windows 7 that i lost password for so I am stuck a login screen. I want to boot the Mac os x from the startup but I'm getting errors and GRUB on command part. So lost not sure what to do, Do I need to first get bypass the password or is the cd compatitabilty the issue? I'm not familiar with macs at all... And help or suggestions will be greatly appreciated.

    [C] key is used to boot from a CD, [D] key is useful to boot from a DVD, better is to hit [alt] to choose any bootable OS even on a USB drive.

    Now using password resetter from Install drive, you'll be able to reset OS X admin password only but there's no OS X admin password to reset on a Windows installation.

    I guess Windows is installed on an NTFS partition, right ? So OS X installer wouldn't be able to write on it. Better would be to install it on an external FAT 32 drive OSX Installer is able to manage formatting it as HFS+, then you'll need to install NTFS tool before to format internal drive.
