    I have a problem with a Windows 10 PC in a german community that the cumulative updates cannot be installed on a computer.

    There is the error that the system reserved partition does not exist.

    I hope this doesn't become a problem for you.

    Is there a way to create one when there is none to begin with ?

    It is possible.
    Maybe there is a thread here that has dealt with the topic.

    Thank you Tekkie Boy.

    If I run into problems with the next drive, should I post them here or start a new thread ?

    You´re welcome.

    Just post it here.
    It's actually about the same computer and the same topic.

    Hello Tekkie Boy,

    I have successfully upgraded the last 3 drives from Windows 7 Pro 64 bit to Windows 10 Pro 64 bit.

    The first of the three had the non-standard drive letter assignment. However, just as you thought, it was not a problem and the drive upgraded without error. The only special steps I took were to do a "clean boot" of Windows 7 by disabling startup items in msconfig.exe run as administrator, and to choose no updates during the setup process. After the upgrade, I used Paragon Hard Disk Manager 17.20 Advanced run from a DVD-R with Win PE 2004 to resize and move the partitions (one partition at a time). Then I used the Disk Management in the Windows 10 OS to correct the drive letters. I rebooted twice after each change. Of course it took a long time with the HDD maxed out at 100% and the activity light solidly lit for a very long time. When I found a break in disk activity, I paused Windows Updates for as long as it would allow.

    The next drive had a standard setup of drive letters, but failed the upgrade in the same way as the drive you helped me with. It is possible that the base set for the drive you helped me with originated from this drive. Rather than start collecting the log files to post, I took a leap of faith and tried the same fix you devised for the prior drive upgrade. That is, the steps listed above in this thread. It worked perfectly again, and allowed the upgrade to proceed and complete.
    Bravo to your skill !!

    The final drive to upgrade, I did a little different. I could not endure the lengthy periods of time while the disk was maxxed out doing its upgrade and update yet again, (yes I know I did not have to babysit it, but you still have to keep checking on it), so I purchased an SSD. I used Acronis Cyber Backup Standard Workstation 12.5 run from a USB Flash drive with a Linux OS on it to do a disk image of the HDD. Then I restored that image to the new SSD. After verifying that all seemed working, I did the upgrade to Windows 10 on the SSD. Wow, what a difference in speed. Even on my 10 year old motherboard with only IDE - SATA mode enabled, the difference was dramatic. I was able to do ALL the Windows 10 updates also. Definitely a worthwhile upgrade.

    I am very impressed by your rescue of my bcdstore. Could you point me to a website that has either HTML or PDF articles / tutorials that explain in-depth the BCD and the associated Command Line commands and options ? I would like to learn more about this.

    Thank you for all of your help. I will send you a PM further thanking you.

    Hello @Win10Newbie9000

    Thanks for the kind words and your detailed feedback.

    I am pleased to hear that you have now been able to upgrade the remaining drives to Win 10 and that I was able to teach you something more instructive.

    You’re right, the installation of an SSD can bring an enormous speed advantage even with older computers.

    I've already made the experience.

    You can find a lot of stuff on Microsoft's documentation pages.

    If you enter the following search parameters in Google search, you will find the Informationen directly on the page on which you want to search.

    For example: bcdedit


    I had recently written to you that I had the case in the german community with the missing system-reserved partition.

    I closed the case as follows:
    I created the missing partition with the help of a partitioning program in front of the Windows partition and at the same time a mini partition of 16MB behind it, which I can set up as an MSR partition in a Uefi computer in the event of a move.

    Then I formatted the system reserved accordingly and created the boot files accordingly on the new partition.

    The failed updates could then be installed straight away and the Windows 10 20h2 could then also be installed without any problems.

    I will reply to your PM later.

    Take care and stay safe.

    Friendly greetings
