Removing Windows XP from a Windows 7 dual boot system

I’ve made the switch to Windows 7 on one of my machines.  It’s time to wrap my head around this new beast.  I installed Win7 x64 on a second hard drive and was dual booting the system for some of the tools I needed.

Now that Windows XP mode is up and running and documents were transferred, I decided it was time for XP to go, cutting the cord.  Unfortunately it’s not as easy as just removing the hard drive and calling it good, though the process isn’t all that hard. NOTE: Do at your own risk; I’m not responsible for damage.

  1. Start the machine in Windows XP
  2. Show hidden files and folders if they aren’t already and copy the “boot” folder and the bootmgr file to the Win7 drive.
  3. Shut the machine down, remove the XP drive and boot off the Win7 DVD
  4. Enter the System Recovery mode after the machine boots and click “Next” to enter the Recovery Toolbox
  5. Click “Command Prompt” and type:
      "bootrec /fixmbr"
      "bootrec /fixboot"
  6. Reboot into Windows 7 and open a command prompt. Run the following command to remove the other second boot option:
      "BCDEdit /delete {ntldr} /f"

Wow. It's Quiet Here...
