xp home edition MBR messed up
« on: November 26, 2007, 06:50:48 PM »
I went to make a norton's ghost image of my hard drive.  something went wrong.  My master boot record got screwey.  I now have to use a start up floppy made from a program called xpquick.  A mentor of mine tried to set the boot.ini file and copy two other standard windows boot files but that did not work.  Bios changes do not work either.
  Its no big deal but i would like to fix it.  any suggestions ?

    1.  Error Message?  It would be helpful to know what the current symptoms/error message is when you try to boot from the hard drive?  Knowing how far you get in the boot/startup process helps identify where the problem occurs.


    2.  Since the boot floppy works; then regarding the hard drive it is my guess:

        a.  The Master Boot Record (MBR) structure is ok because your system is able to access the hard drive and read files on your boot volume (containing Windows XP operating system).

        b.  The primary partition containing your system volume (C:?) may not be set "active" in the partition table of the MBR.  I'm wondering whether it got cleared by the Ghost program.  During startup you look for the system boot files in the "active" primary partition.  If it isn't set "active" or the appropriate system files aren't there, the hard drive will not boot.

        c.  The Boot Record on the "active" primary partition (system volume c:) may be damaged/corrupt or no longer pointing to correct location of NTLDR.

        d.  NTLDR, NTDetect.com, Boot.ini issue.  Any one of these files could be missing, damaged, corrupt or in the case of Boot.ini; misconfigured.  Sounds like your friend probably checked for this or replaced them with "fresh" copies.


    3.  Start by determining whether the primary partition containing the system volume (logical c: drive) is set "active".  Use your boot floppy to boot into Windows XP.

    What is the logical structure (division into logical drives) of your hard drive?

    If more than one logical drive, what does each logical drive contain (ghost, windows)?

    Is the system volume, logical c: drive, a "primary" partition and is it set "active"?
    Is it the only primary partition that is set active?  If there are other primary partitions are they also set "active" (they shouldn't be)?

    Use the "Disk Management" tool to do this (hope Windows XP Home Edition has it).  One way to access tool is:

        a.  Left click on "Start" button, start menu is displayed.
        b.  Right click on "My Computer" item, a drop down menu should appear.
        c.  Left click on "Manage" item, "Computer Management" window should open.
        d.  Under "Storage" subcategory, left click on "Disk Management".  Right hand pane should include all your hard drives with partition/volume.
        e.  Find the system volume on the bottom half of the right pane.  Is it "color" coded as a primary partition (dark blue, I believe)?
        f.  Right click within the system volume.  From context menu you should see something like "Mark active partition".  If you're on a primary partition and the item is grayed out, I think it's currently set active.


    4.  XpQuick.  And thanks for the "tip" about xpquick.  I'll have to take a closer look at it.

    You could also try running fixboot and fixmbr from the Recovery Console...
    Do you have an XP CD ? ?

    thank you.  the disk management tool did the trick.  my c: drive was not set to active.  The reason I was vague at first was that I would get no error.  Just a flashing cursor. Norton's ghost must have messed this up.

    Ghost is a powerful but useful tool...
    It's best to be prepared before using...
