برای نصب با Parallels این راهنما رو بخوانید:
و البته این صفحه:
و اما راهنمایی که من استفاده کردم:
*Make sure to back up your HD before you start this, Disk Utility deletes everything!*
1. Boot from Cd-Rom drive by restarting and pressing 'C' while the Mac restarts.
2. Once you enter into the installation program, click on Utilities from the menubar and select Disk Utility.
3. Partition your disk into 2 parts. The first one (i.e. the top partition) you will leave as Free Space for Ubuntu. The second one (i.e. the bottom partition) you will partition as Mac OS X Journaled (Extended). My partition sizes were 20 Gb for Ubuntu and 60 Gb for Mac OS X.
4. After partitioning your HD, (re)install Mac OS X. Go through the whole installation set up and reboot.
5. After you have OS X up and running, insert Ubuntu install CD and reboot from the Cd-Rom drive by restarting and pressing 'C'.
***Make sure you don't have any external hard drives connected to your Mac at this point! It's the external HD that makes Ubuntu unable to install yaboot!***
6. Once you are to the Partitioning screen, choose "Use largest free space". This tells Ubuntu to install on the first partition we made earlier.
7. Ubuntu should then go ahead and create the partitions it needs and install the base OS and yaboot.
8. Sit back, reboot Mac, and yaboot will ask if you want to boot Ubuntu (press 'L') or OS X (press 'X') or from Cd-Rom drive (press 'C'). Press 'L' and enjoy!
با این تفاوت که در مرحله ششم من گزینه Manual رو انتخاب کردم و خودم فضاها رو مشخص کردم نه اینکه از Use largest free space استفاده کنم.
فراموش نکن که حتما از اطلاعاتت نسخه پشتیبان تهیه کنی.
