Multi-booting examplesEdit

With Windows Vista and Windows 7Edit

  1. Make sure that you have enough space to install Windows 7.
  2. If you have already created a separate(empty) partition for Windows 7, skip this and move on. Otherwise,
    1. Open Disk Management by going to Start and typing 'Disk Management'.
    2. Right click the volume and click Shrink Volume.
    3. Select the amount to be shrinked. This will be the partition size as well.
    4. Right click on the new partition and click Create New Volume
    5. Select all the free space gained by shrinking to be allocated to the new partition. Choose the format option as well and give it a name.
  3. Install Windows 7.
    1. If you have a disk, you can simply insert the disk and run the installer. Choose the new partition when given the choice of partition. Make sure that you're not overwriting Windows Vista itself!
    2. If Windows 7 is somewhere on the HDD, simply navigate to the location and start the installer.

With Windows XP and Windows 7Edit

The ability to resize disk partitions was introduced only with Windows Vista, so for a user currently running Windows XP and wanting to dual boot with Windows Vista or higher, he/she should be having a separate partition for that OS. Otherwise, he needs to use a 3rd party tool of reinstall. Make sure that you have a separate partition. If you have, move to Step 2, otherwise if you are using a partition tool, use that and move on to Step 2. If you'd rather reinstall Windows, continue.

  1. Reinstall Windows. To do so,
    1. Locate your Windows XP disk.
    2. Restart and enter to your BIOS's One-time boot. If you do not know how to do so, refer to your documentation. If on entering the One-time boot, there is no option to boot from CD, refer to your BIOS on how to enable booting from CD.
    3. Press any key when prompted to do so.
    4. Follow the on-screen instructions.
    5. Delete the current partition. Make sure that your files are backed up!!
    6. Create 2 partitions with appropriate sizes. Make sure to leave enough space for the new partition. You may want to create additional partitions, do so.
    7. Install Windows XP on the first partition.
    8. Once you've got a brand new copy of Windows XP running, move to Step 2.
  2. Install Windows 7.
    1. Locate your Windows 7 and start the installer.
    2. When you're given the choice of the partition, select the other empty partition. Make sure that you're not overwriting Windows XP itself!

OSX and Windows 7+Edit

This section applies to version 4 of Boot Camp.

This section concerns mostly those who are trying to dual-boot Windows 7+ on their Intel-based Macs. Before you start, update your Mac to the latest that is supported, and update BootCamp. If you have BootCamp 3 or below, see your Boot Camp documentation. This guide is intended for users with Boot Camp 4 or higher. If you plan to use Windows 8 or higher, you should upgrade to Boot Camp 5 and higher. If you do want to use 32-bit Windows, do not upgrade beyond Boot Camp 4(but use the latest in that), as Boot Camp 5 is for 64-bit Windows 7+ only. Do not use a Enterprise SKU. You'll end up being unable to install by a GPD error. To start,

  1. Prepare your Mac by following the instructions above.
  2. Decide whether you're using a USB drive or a DVD. USB is better, but not every Mac supports it. Most models from 2010-2011 support this. Go to the Apple website to verify this. If DVD is your option, you'll still need a 2GB+ USB for Boot Camp drivers.
  3. Make sure that you have sufficient space.
  4. Open Boot Camp. It's mostly in the Applications folder. Click Next.
  5. Select all the options. If you're using a DVD, unselect the first option. That option uses a ISO file and erases the USB and copies the contents into that. If you're already having a USB with Windows installer, remove the first option.
  6. Select the ISO and the drive to which it will copy the file. The drive will be formatted, so make sure that you've backed up your files on that drive..
  7. Once that's done, if you've selected the option to download Boot Camp drivers, it may ask you where to save that and then will begin downloading the files. Select a USB drive(your files won't be affected) If you've selected the first option, this is not required as that'll be already done for you.
  8. Select the partition size. It is better to allocate atleast 30 GB of free space.
  9. After formatting, the computer will restart. Stay alert at this time.
  10. When the Mac 'chime' sounds, immediately hold the option(ALT) key. Keep holding till a boot menu appears.
  11. At the boot menu, select the USB/DVD drive containing the installer.
  12. The Windows setup will start. Select your preferences and click Next.
  1. Proceed till you reach the page which asks you to select your partition.
  2. Select the BOOTCAMP partition and format it.
  1. After that, click Next to continue. Wait till you reach the OOBE(Out of Box Experience) where you configure the settings for first run. You would've seen this on first run after buying a new PC. Complete the OOBE.
  2. Before/After you see the desktop, you'll see a Boot Camp installer if you've left the USB connected. If you did not, then start the installer by connecting the USB and then starting the installer setup. Complete the installer and restart when prompted to do the same.
  1. After restarting, your Mac should boot to Windows. If you want to boot to OSX permanently, you can do so though Boot Camp. If temporarily, hold down the ALT(Options) key when the Mac chime sounds and select your OS.
