Installing Windows, Linux and Yosemite inside Mac

This post tells you how to install Windows and Linux within Macintosh Machine (Yosemite)
Base OS: Yosemite
Other OS: Windows 8.1, Fedora 21 (Linux Mint 17.1 also)
Machine used: Mac Mini (Mid 2013)

Installing Yosemite

Step 1: Install Yosemite (If you have mavericks, download it from the Store and install it)

Installing Windows 8.1 

  • Open Boot Camp and select "Install Windows 7 or later" and also select "Download the support Softwares for Windows 7 or later", You need to provide a FAT partitioned Pen Drive (This wil be another pendrive other than the Windows 8 Boot Pen Drive, if you dont have any other pendrive, leave this step, after installing Windows you may come back and download the support softwares) and Click Next.
  • Now Mac will ask for partitioning your hard disk into two (Select atleast 50GB for installing Windows).
  • Reboot and Press the "Option" button and select Windows (You have to insert the USB that boots Windows 8.1)
  • Everytime when Mac restarts, you need hold the "Option" key to select the Windows OS.
  • Once Windows installed, Open the FAT Pen Drive with the support software (There will be folder called Bootcamp, open it and click the setup.exe and wait till all the drivers are installed and you can see a bootcamp icon in the bottom right task bar)
  •  Thats it.... (Hold the "Option" Key everytime if you want to select the concerned OS (Mac or Windows)

Installing Linux (Fedora 21 or Linux Mint 17.1 or Ubuntu 14.04.1) 

  • Make a bootable Pendrive with either of these three OS (in my case, i used Fedora 21 64 bit)
  • You need to make the bootable pendrive that suits Mac... Here are the steps
  • Copy the Fedora-xx.iso file in Desktop and issue the command 
  • $] hdiutil convert -format UDRW -o ~/Desktop/fedora21.img ~/Desktop/Fedora-xx.iso
    $] diskutil list
    Select the appropriate disk (in my case/dev/disk2) and make it bootable by the following command
    $] diskutil unmountDisk /dev/disk2 
    $] sudo dd if=~/Desktop/fedora21.img.dmg of=/dev/rdisk2 bs=1m
    (you can use /dev/rdisk2 for faster operation, else you can use /dev/disk1, also remember i did all my work at the Desktop so, i put ~/Desktop, 
    in your case you can change the alternate location where you stored the iso and img) 
    $] diskutil eject /dev/disk2 
  • Install rEFInd for Mac
  • To install rEFInd, unzip rEFInd and open the folder, Open Terminal and drag the from the rEFInd folder and drop it to the Terminal and press Enter... 
  • Open "Disk Utility" by pressing the "Command+Space Bar" and shrink the boot space for Linux (20GB is the minimum recommendation I suggest). You can see the picture below. (The first image shows the unshrinked partition and the second image shows after shrinking)

  • Once done, Shutdown the machine and then Power ON. 
  • Select the Linux OS from FAT Partition and boot and install Fedora 
  • if You get the following error, "sda may not have enough space for grub2 to embed core.img" during the partition, you can reboot the machine and Hold the Option key and then select the Fedora Linux.
Once everything is installed, you can continue to boot Mac (Yosemite) or Windows 8.1 or Fedora 21..... So all three OS in a single Machine.....
