A recovery partition is a section of your hard drive set aside to repair the computer in case your main Windows partition corrupts. You use this partition to restore the computer to its original settings. This type of hidden partition is used by computer manufacturers, but you can set your own recovery partition. You need spare space on your hard drive, or you can use a recently installed hard drive for the partition space.
Place your Windows installation DVD into the computer's drive. Click the Windows "Start" button and select "Control Panel." Click "System and Security," click "Administrative Tools," then double-click "Computer Management."
Click "Disk Management" on the left side of the window. This lists the extra hard drive space in the centre detail pane. Right-click the extra hard drive space labelled in black and select "New Simple Volume." This opens a wizard. Click "Next" on the first window.
Type a size for the partition. The size units are megabytes. Windows defaults to the total amount of disk space, so you can also leave this default. Choose a drive letter from the drop-down box. Click "Next." Leave the format option checked and click "Next." The wizard creates the partition for the recovery files.
Copy all files from the installation DVD in the drive to the new partition letter. After the files finish copying, click the Windows "Start" button and type "cmd" into the text box. Press "Enter" to open the Windows command line.
Type the following into the command prompt where "X" is the new drive letter you chose in step three:
bootsect /nt60 X:
These commands create the hidden recovery partition you can use if your main partition fails.
