    Installation error - Build 7000

    e6600 2.4ghz
    500GB HDD
    2 GB RAM

    Windows XP Pro

    Mounted .iso image and proceeded to do a clean install, got till the end of the installation and an error saying: "Windows could not update registry data in the installation" popped up and reverted my setup back to Windows XP.

    I don't have DVD burner so I don't have the option of burning the .iso to a DVD.

    I tried setting up a dif. partition thru PartitionMagic but was not able to...

    Help? TIA

    Found this post related to a Vista installation:
    I got the message "Windows could not update registry data in the installation." on several attempts to upgrade Vista. Each time, I uninstalled more software (including parts of IIS that caused some other folks trouble).

    I also checked my event logs (using eventvwr.exe) and cleaned up problems reported there until no more errors were being logged.

    Then I found the file C:\$Windows.~BT\Sources\Rollback\setupact.err had some useful info. An error message there suggested trouble with the HKLM\SYSTEM\MountedDevices key in the registry.

    I cleaned out some old entries from there, rebooted, and tried the upgrade again. This time it worked (although it appeared to freeze a couple of times toward the end, requiring a hard reboot -- scary stuff).

    If you want to try cleaning up the MountedDevices key, read up on it first to avoid causing more problems, and save the existing data there first. I kept the \DosDevices entries and \??\Volume entries for my floppy and hard drives (A:, C:, F:) and removed all the other entries. On reboot, Windows rebuilt the entries for my CD and DVD drives.

    Gonna check it out..

    Hi Albert,

    That link could well be right. A clean install will be a better bet.
    You may need to create a partition and format to NTFS before you begin to install 7. How come you couldn't create another partition - any error messages?

    Hope it helps

    It looks great!

    Type regedit in run via the start menu.

    Navigate to HKEY_LOCAL_MACHINE
    Navigate to SYSTEM
    Navigate to MountedDevices
    Delete all entries except for the /DosDevices entry pertaining to your main hard drive.
