Step B: Use Windows’ Disk Management to shrink the partition (see Resize a Partition for Free in Windows 7 or Vista). Step A: Use the Windows defragmenter or a third-party defragmenter to defragment the Windows partition.
Stage 1: Reduce the size of the existing Windows partitionĭo not use the partition managers Parted, GParted or KDE Partition Manager to reduce the size of the existing Windows partition, or you will damage your Windows installation. If you already have Windows installed, the procedure to prepare the PC and install Linux is divided into the following three main stages. So, to reiterate, the method described below avoids two potential major problems: 1) it avoids the possibility of making a Windows factory restore partition unusable 2) it avoids the possibility of Windows applications overwriting some of the GRUB 2 code. The method described below does not install any GRUB 2 code in the MBR, and thus it will avoid this problem. See the blog article Windows applications making GRUB 2 unbootable for details. Note also that some Windows applications can make a PC using GRUB 2 unbootable if GRUB 2 is installed in the MBR. If the contents of the original MBR are overwritten - even if it is only by using the Bootrec.exe tool on a standard Windows Vista/7 Installation DVD - then the manufacturer’s code will no longer be in the MBR and so it will no longer be possible to boot the hidden factory restore partition by pressing the key(s) specified by the manufacturer. The reason why this is the best method is because it does not alter the contents of the MBR (Master Boot Record), which, in addition to the Windows bootloader, may contain code created by the manufacturer to boot the hidden factory restore partition instead of the Windows Vista/7 partition if it detects that you pressed a defined key or keys while the PC is booting. If you already have Windows Vista or Windows 7 installed in a single partition, then the method described below is the best way of ensuring that your Windows installation will still be bootable even if the Linux installation or GRUB bootloader become damaged in future.įurthermore, if your PC has a hidden factory restore partition for Windows, the method described below is the best way of ensuring that you will still be able to recover Windows in future using that hidden partition.

I’m going to explain how to configure your PC in order to dual boot Linux and Windows Vista or Windows 7, assuming Windows is already installed.
