Dual-booting all versions of Windows and Linux
Install Windows-controlled Dual-Boot of Fedora 16 on a Windows 7 computer with one hard disk (Win7 installed first and Win7 still controlling startup after Linux installation)
Last reviewed: April 2012
If you have one hard disk, this guide shows how to leave Windows 7 unaltered when you create a natural dual-boot of Windows 7 and Fedora 16 when Windows 7 is installed first. The Windows 7 boot loader will stay in control (not Linux's GRUB). You can then run either by selecting one from a Windows 7 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.
If you have two or more hard disks (even if installing Fedora on the first disk), you must go to this page
If you prefer Linux Fedora's GRUB to control the dual-boot, go to this page
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 you 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
EasyBCD. The highly-acclaimed EasyBCD is a free editing utility that allows any user to easily edit the Windows 7/Vista boot menu (the BCD or Boot Configuration Data). Some settings, not used here, are very advanced. EasyBCD works in Windows 7 and Vista, but also in Windows XP if you first install Microsoft's .NET 2.0 Framework.
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 with one hard disk(Advanced Users)
That's it! The Windows boot loader menu will boot Linux Fedora 16 and Windows 7.
STEP-BY-STEP: Install Linux Fedora 16 when Windows 7 was installed first -and you have 1 hard disk
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.
A. Make your preparations
B Make space (Unallocated) for Fedora 16
You must create disk space and leave it as Unallocated. 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 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.
Always make a note of the size of the Unallocated space (it will be named 'Free' in Linux).
C. Install Fedora 16
Raid/LVM was not an issue when testing so partitions were created manually during installation. Fedora was installed with Grub 2 placed on the Linux EXT4 partition. The originally Active partition always remained Active after Fedora 16 installation so Windows then booted automatically. Finally EasyBCD created the Linux Fedora 16 entry in Win7's boot manager thereby creating the Windows dual-boot.
D. Put a Linux Fedora 16 boot option in Windows boot loader
Congratulations! You have created a natural dual-boot of Windows 7 and Linux Fedora 16 on a single hard disk with Windows in control when Windows 7 was installed first.
Footnote: EasyBCD creates an NST folder on the root of the Windows partition when it adds an operating system to the Windows 7 boot loader. This NST folder contains one or two files vital to booting the added OS. Be sure you do not accidentally delete it.
Uninstall/Remove Linux and reclaim space
Linux Fedora is wonderful, regularly updated, and it's free! Nevertheless you may wish to remove it at some stage. Removing Fedora from this dual-boot, and regaining its disk space, is quick and painless.
In just a few second you will have all the Linux space back in Vista. Restart computer.
Note: EasyBCD has an Uninstall shortcut in Start > All Programs > NeoSmart Technologies.
Repair Windows 7 Startup
You will not have any problem if you follow the instructions as stated above. However you might encounter some freak occurrence like a power failure during an installation. Windows 7 should always boot again if you execute the following procedure.
If still stuck for a solution, boot again from the installation DVD, select Repair your computer, highlight Windows 7, get to a Command Prompt, use DIR command (DIR C: or DIR D: etc.) to identify drive letter allocations (sizes and Labels will help), and type in:
Help! I get only the GRUB boot menu!
If you only get a GRUB boot menu on bootup, then GRUB was mistakenly installed to the Active partition, (hd0) - probably the Windows partition. The Windows boot loader has been overwritten by the Linux version but it's easily recovered.
