    How to uninstall Windows XP from dual-boot with Windows 8?

    I have a dual-boot system with Windows 8 and Windows XP.
    Now, I need to uninstall Windows XP so that I can install Ubuntu.

    But the problem is the partition having XP is active and it is the system drive.
    I think even the MDR is located in XP partition.

    Here's a screenshot of my Disk Management window:

    Please help me to uninstall XP.
    THANKS in advance

    Please backup any thing necessary so you can revert back if things go wrong,.
    1. If you don't have the Windows 8.1 Installation disk then you need to create a USB/CD Recovery disk:
      - From Control Panel ->Recovery and follow the steps.
    2. Win+R -> then type msconfig and delete the entry for Windows XP from the Menu and set Windows 8.1 as default.
    3. From Disk Management, delete the Windows XP partition.
    4. Set your BIOS to boot from USB/CD then Use the Windows 8.1 Installation or the Recovery disk to boot up your PC, If you boot from the installation disk, click on Repair my PC first else
      Trouble Shoot->Advanced Option->Startup repair->Windows 8.1
    5. This should create a new MBR in C partition and set it to active (Windows 8.1).
    6. Take out the USB/CD then reboot.

    NOTE: For Windows 8, the options in step 4 is: Trouble Shoot->Advanced Option->Automatic Repair
