Introduction

This guide shows how to put Linux in control when you create a natural dual-boot of Windows 7 and Linux Fedora 14 if Windows 7 is installed first. A new MBR will be created at the start of the disk and Linux's boot loader (GRUB) will be in control of startup. You can then run either by selecting one from a Linux menu during bootup. No data loss will occur and a third-party boot utility is not used.

In this procedure you need to shrink the Windows 7 drive to make room for Linux. The example shown here uses one hard disk.

32 and 64-bit versions of Windows 7 Home Basic, Enterprise and Ultimate were used in testing so this will also work with Windows 7 Premium and Professional. The computers used were (1) a 32-bit Dell Optiplex with Pentium 4 (2.26GHz), 2.0 GB RAM, 160 GB ATA hard disk, and (2) AMD Athlon 64-bit (2.4GHz), 2.0 GB RAM, 1 TB SATA hard disk.

Following these instructions correctly should always succeed. However, any change to your computer should not even be considered unless your have a rescue plan. This guide also contains that rescue plan - just in case!

The procedure used is suitable for experienced computer users.

Important Installation Notes

Shrinking a Windows 7 or Vista drive
If possible, you should avoid resizing a Windows 7 or Vista partition with a third-party partitioning utility like GParted. Windows partition editors often use different disk geometry than that used in Linux. Therefore resizing a Windows partition outside of Windows control could sometimes make Windows unbootable.

Shrinking a Windows 8, 7 or Vista drive. You should use Shrink in Windows' Disk Management to resize the Windows partition. You can read Shrink the Windows 8. 7 or Vista Partition for instructions on completing this task successfully. Use the free GParted Live CD to gain disk space only if you must - read the page Use GParted to Resize the Windows 8, 7 or Vista Partition to learn how.


SUMMARY of Procedure (Advanced Users)

  1. Backup.
  2. Create Unallocated space for Linux at end of Windows NTFS disk (use Shrink in Disk Management).
  3. Install Linux Fedora 14 on the free space
    - select "Create custom layout" and create partitions yourself.
    - install GRUB on the MBR (the default for "Install boot loader on ...").
  4. Restart computer. Select which OS you wish to use from the GRUB menu.

That's it! The GRUB boot loader menu will boot Linux Fedora 14 or Windows 7.

STEP-BY-STEP: Install Linux Fedora 14 and GRUB when Windows 7 was installed first

It's the nature of a step-by-step that it appears long and difficult. Not so!

Installing other operating systems on your Windows 7 computer may invalidate your warrantee.

It's important to follow the instructions exactly as stated and you should have a properly working Windows.


Requirements

  • Installation CD/DVD for Linux and preferably Win7's DVD.
  • 1 download.
  • A first hard disk that uses only NTFS and contains a working Windows 7.

A. Make your preparations

  1. Backup important data before making any changes to a partition. You can burn files to a CD, clone an image of your hard disk, copy files to a USB flash/pen/thumb drive, or use an USB external drive (a good choice)
  2. Download Fedora 14, standard or 64-bit version from http://fedoraproject.org/. You can use the excellent free GetRight download manager to help with the large download. Create the Fedora Live DVD from the downloaded .ISO file.
    Optional: Download NeoSmart's free Windows 7 System Recovery Disk if your Win7 DVD is missing!
  3. Disconnect all external devices before you start.

B. Make free space (Unallocated) for Linux

You must create disk space and leave it as Unallocated or Free (not formatted). Decide first on how much disk space you wish to allocate to Linux and if you will create an extra partition (/home) for your Linux data. This data partition can be left intact should you wish wish to reinstall Linux at a later time. The Swap area size should be about twice your RAM size but you should allow less than twice if you have a lot of RAM.

Make a note of the size of the Free/Unallocated space.

  1. Restart computer correctly (close all programs/software before Restart).
  2. Open Disk Management in Windows 7 (right-click Computer, select Manage, click Disk Management).
    • Note which partition is marked Active.
    • Right-click the Win7 volume, and click Shrink Volume.
      • In Enter the amount of space to shrink in MB: enter enough for Linux and its Swap file.
      • Click the Shrink button (it may take some time!).
        Note that we are leaving the newly acquired free space as Unallocated.
      If Shrink does not give you sufficient Unallocated space, read how to Shrink the Windows 8, 7 or Windows Vista Partition for instructions or use the free GParted Live CD. Then return here.
  3. Restart to Windows 7.
    • Open Disk Management and check that the change made is correct.

C. Install Fedora 14

Raid/LVM was not an issue when testing so partitions were created manually during installation. The default location for the Boot Loader was accepted (to the MBR). The dual-boot was created automatically by Fedora. Finished.

  1. Bootup from the Linux Fedora 14 Live CD.
    Double-click the Install to Hard Drive Desktop icon (Activities > lowest icon).
     
  2. Click Next and then select the appropriate keyboard.
    Then select Basic Storage Devices (unless you have a non-standard setup).
    Now tick the check-box for the hard disk drive where Fedora will be installed.
    Enter a name for indentification.
    Select the correct city for your time-zone.
    Create a Root Password of your choice (and remember it!).
     
  3. Select Create Custom Layout in the next screen (that's VERY important).
    • Highlight the Free space you created for Fedora, and click the Create button.
    • In Create Storage, select Standard Partition, and click Create.
      The Add Partition window will open. First create the Linux EXT4 partition.
      • In Mount Point:, select / (a forward slash).
      • In File System Type:, select ext4
      • In Size (MB):, enter all available space (for Fedora) except 2 GB (for the Swap File)
      • Leave Fixed size checked.
      • Click the OK button.
    • Highlight the remaining Free space, and click the Create button.
    • In Create Storage, select Standard Partition, and click Create.
      The Add Partition will open. Now create the Swap partition.
      • In Mount Point:, leave it blank.
      • In File System Type:, select swap.
      • Tick to enable Fill to maximum allowable size
      • Click the OK button
        (it's fine if the Swap is made a Logical partition in an Extended partition).

      Click Next when ready, or click Back to recreate partitions.
      Then click Write changes to disk or Go back if unhappy with the changes.
      The new partitions will now be created on the disk and formatted.
       
    • The next screen is vital to ensure the correct location for GRUB.
      • If you wish to overwrite the Windows MBR and boot loader, leave the default at Install boot loader on /dev/sda or /dev/hda
    • Using a boot loader password is optional.
    • Under Boot loader operating system list,
      highlight the Device labelled Other and click the Edit button.
      • In Label, enter a name like "Windows 7".
        Leave Default Boot Target unchecked unless you want Windows 7 to be the default.
      • Click OK.
  4. Click Next and the install process will start.
     
  5. Restart the computer when Fedora installation is finished (remove the DVD).
    Let Fedora boot automatically and it will quickly finalize its setup.
  6. Restart computer again.
    Press the required key (within three seconds!) when you see Press ... key to enter the menu to access the Linux boot menu which will allow you to select Windows 7 or Fedora..

Congratulations! You have created a GRUB-controlled natural dual-boot of Windows 7 and Linux Fedora 14 when Windows 7 was installed first, and the Windows-created MBR and boot loader have been replaced by the Linux version (GRUB).

Help! I want Windows-control back again!

The Windows boot loader can be recovered relatively easily. Please note that doing this will stop you booting to Linux Fedora.

How to reinstall/recover the Windows 7/Vista boot loader (BCD)

If you installed GRUB to the MBR:

Bootup any Windows 7/Vista installation DVD or even from NeoSmart's free Windows 7 System Recovery Disk.
It must be a 64-bit version if a 64-bit Windows 7/Vista is installed.

  • Press a key when you see Press any key to boot from a CD or DVD.
  • Select your Language and then Time....
  • Select Repair your computer (bottom left of the Install now screen).
    An automatic check of your system will run but will not identify GRUB control!
  • In System Recovery Options, highlight Windows 7, and click Next.
  • Click Command Prompt in System Recovery Options.
    • Type in (and press ENTER)
      Bootrec.exe /fixmbr
      exit
      (GRUB will be overwritten and the Windows boot loader reinstalled).
  • Now click Startup Repair in System Recovery Options.
  • Restart computer.
    Windows 7 should boot as originally.

If you want to use the hard disk space currently allocated to Fedora:

  • Boot to Win7 and open Disk Management.
    • Right-click the Swap partition, select Delete Volume..., click Yes.
    • Right-click the Linux partition, select Delete Volume..., click Yes.
    • Right-click the Swap partition, select Delete Partition, click Yes - required for Logical partitions only.
    • Right-click the Linux partition, select Delete Partition, click Yes - required for Logical partitions only.
    • Right-click the partition to the left of Unallocated, select Extend Volume...,
      and click Next to use the maximum space for Windows, and then Finish.
      Alternatively, create a new partition in the Unallocated space and Format it.

In just a few second you will have all the Linux space back in Win7. Restart computer.
