How to convert dual-boot HP Z400 Workstation to Windows 7 only

Below are instructions to convert the dual-boot HP Z400 workstation (shipped in Fall 2012 for use with the Xilinx ML605, Altera DE4-530 and BEE3 FPGA boards) into a Windows 7 only configuration. This provides the benefit of additional hard disk space (2x 1TB drivers), which is currently half-occupied by the Linux partition. Use the following instructions:

  1. Boot the system into Windows 7
  2. Go to Control Panel; select Backup and Restore
  3. Create a system repair disk (burn to a blank CD/DVD and leave in the drive)
  4. Restart the system; press any key to boot from the CD/DVD
  5. You will see System Recovery Options – User Recover Tools; click “Next”
  6. Once you have reached the System Recovery Options screen, select Command Prompt
  7. Type bootrec.exe /fixmbr
  8. Type bootrec.exe /fixboot
  9. Type bootrec.exe /rebuildbcd
  10. Reboot the workstation (remove the CD/DVD) and Windows 7 should boot on its own (no grub loader)
  11. To recapture the disk space used by Linux:
    1. Reboot the workstation and type CTRL+I to enter the RAID BIOS
    2. Select Option 3, and from there select both disks, then OK
    3. Reboot the workstation; Windows 7 will come up with two disks showing
