  1. The XP bootloader writes over the 7/vista bootloader.

    So installing XP on a pre-existing Win7 pc, you'll need to repair the Windows 7 boot file and add XP to the Windows Boot Manager list.

    Either install XP first, or if you've already installed xp on a Win7 PC, follow these next steps.

    1. Run EasyBCD.

    2. On the left side of the EasyBCD window, click on the "Add New Entry" button.

    A) In the top section under Operating Systems, click on the Windows tab.

    B) To the right of Type, select Windows NT/2k/XP/2k3 from the drop down menu.

    Leave the "Automatically detect correct drive" box checked.

    C) To the right of Name, leave the default Microsoft Windows XP as the name to be displayed in the Windows Boot Manager.

    D) Click on the Add Entry button.

    3. On the left side of EasyBCD, click on the Bootloader Setup button, select the "Install Windows Vista/7 bootloader to the MBR" option, and click on the Write MBR button.

    4. Close EasyBCD.

    5. Restart.

    EDIT- If you don't need XP, then click on "Windows XP" and click on "Delete" on the EasyBCD "Edit boot menu" window.

    Also, once you format C:\, the D:\ drive becomes the de-facto C:\ drive (system drive) for the currently installed OS (WIN7 in your case).

    If you again try to install XP or anything else on that drive, the old existing installation (Windows.old or something) will become unrecoverable.

    The files will still work, but it can't be used as an OS any more.
  2. the isse with using thirdparty software is that you will never know when it contains a malware or worm

  3. In general, always install windows OS's in order from oldest to newest in order to prevent the boot loader from being over written with an older version that doesn't know about the newer OS's.
