    I re-installed Win XP on a 1st partition.
    The dual boot need to be re-installed after that...
    Now, when I load Vista, I don't get the desktop anymore.
    When trying to open regedit I get the message: specified path does not exist
    Also when trying to open some programs I get the message: Windows Installer
    Servie is not correctly installed.

    Could I get some help please on this problem?

    Thanks in advance,

    thanks for quick reaction!
    What I did/happened was the following:

    I had only Win XP Home on my Dell machine.
    I was impressed by Vista, that I installed on a new created partition (made
    w/ Partition Magic).
    After the installation of Vista, a boot menu gave me the choice which OS to

    I re-installed XP, first by deleting the partion and than by booting w/ the
    installation CD of Win XP Home.

    When re-booting after the re-install of Win XP, the bootmenu was gone so I
    could not longer start up Vista.

    I used the program VistaBootPro for re-creating the boot menu...First,
    however, I tried the repair function via booting via the Vista Install DVD...

    I succeeded creating the boot menu. I manage to start Vista but when it
    loads it get the message "preparing your desktop", which lasts for a while. I
    end up with an empty desktop.
    When trying to fix or to open programs, I get an error message stating that
    the Windows installer is corrup or not installed. Another message that I
    received when trying to open regedit is that the path thereto is not valid,
    although it should be...

    I think that all these problems are linked to one issue...but I do not know
    the solution...

    I wouldbe gratefull if you could help me...

    Thanks in advance,

    Can you access an elevated command prompt and run "bcdedit /enum"?
    Copy/paste the results into a response.

    Also, when you attempted to do a startup repair with the Vista DVD, were you

    Hello Rick,

    I can not execute anything via the run command...
    I can load the explorer via task manager/new task...but it is temporary
    profile that is loaded. No program can be recognised (I can for example not
    load Office 2007 programs), nor execute regedit...
    I think I has something to do w/ the MBR file, can it be?

    Check BOOT.INI to see if VISTA is in Section 2 of partition 2. I saw
    something in a MS KB article about these kind of problems happening after an
    OS is installed in blank disc space ahead of VISTA's partition.
