    No system reserved partition


    Installed a Samsung SSD on my Asus CM6730-06 desktop running Win7. the Win7 OS was cloned from the Asus Pc to Samsung SSD. Windows 7 runs great off the SSD. Got a Windows 10 upgrade notice and received an automatic download of Win10 but when it tries to install I get the message "Windows 10 couldn't be installed". "We couldn't update the system reserved partition". I would like some help to upgrade to Win10 on this pc. Thank you

    :)

    No Windows 10 System Reserved Partition (Can't Update)

    Hi Andre,

    I downloaded the ISO, mounted it, and when trying to install, I got this message:


    No system reserved partition [​IMG]


    I then found a post here: "You can't install Windows on a USB flash drive using Setup."

    ...that said to change a registry key from '1' to '0' (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PortableOperatingSystem)

    On doing this, I could now run Setup from the mounted ISO.

    I sucessfully updated Windows 10, and as you thought, it created a new partition, which can be seen below. (It shows as Recovery Partition instead of System Reserved, however, and it appears after the primary partition instead of before??)

    Hopefully I wont have any further issues updating in the future.

    Thank you both for your assistance.

    Kind regards

    Euan

    Yes, it would, but in your case, it might not, if you use the ISO file. Windows 10 setup would automatically create it. Did you try using the ISO file to upgrade?

    Post a snapshot of a fullscreen Disk Management Window:
    To open Disk Management, press Windows key+r, type diskmgmt.msc and press Enter or click GO. Make it full screen. Expand the fields as necessary so everything can be seen.

    I think I have some similar problem, windows 7 update says "windows 10 couldn't be installed" with error: 80070006-2000C.
    I'm pretty sure its a system partition related problem based on what meager info I could turn up.
    After checking it turns out that I don't have a system reserved partition; the primary partition has the system and boot files - could this be a problem? It's factory installed Asus n53jq , apparently they decided to put everything in the main partition, possibly that's causing a problem.

    You can try using MiniTool partition wizard to shrink your main partition, leave 600 mb free in front of it. That should give Windows 10 plenty of room to create a recovery partition. Not sure if it will create the recovery partitions on an upgrade though.

    You might have to do a clean install of Windows 10 (skip any time that it asks for a product key), deleting all the partitions on your hard drive first - that will definitely create the recovery partitions - but it won't activate. Then you would do a clean install of Windows 7, just select the big, main partition as the install location - don't delete partitions. You do have a Windows 7 product key? That should leave the needed recovery partitions intact. When Windows 7 activates, you can upgrade it to Windows 10.

    Of course any clean install will erase all your programs and data.

    Thanks, can anyone advise if leaving some empty space will work?I'm a little leery of crashing my system, I don't really have time for that right now. or is there a way to manually create a system reserved partition by copying the boot folders over and making it active?

    the clean install is a route I would prefer not to go; I have a ton of software installed, but if I must it would be a good chance to upgrade to an ssd.

    On my system, a clean install of Windows 10 Pro from a retail distribution media (not the upgrade) I have four partitions, Recovery (450Mb), System (100 Mb), Reserved (16Mb) and Primary (the rest of the drive).

    The reserved partition does not show in diskmgmt.msc, but I can see it using the "list part" command in diskpart.exe

    Were you able to resolve this by creating a new system reserved partition? I have almost exactly the same issue. I have a Vaio laptop and migrated my Win 7 install to an SSD, which left me with no system reserved partition. I used the instructions linked in this thread to create a new system reserved partition, but I'm still getting the same 'Couldn't Update the System Reserved Partition' error. Anyone know if there is something else I can do to get the upgrade to work? I really don't want to do a fresh install of Win 7 (assuming that would work)? My dismgmt screenshot is below.

    Strange, you shouldn`t need a SR partition to do an upgrade.

    Attachment 32696

    Did the Windows 7 install drive have a SR partition ?

    Not sure. After I migrated to the SSD, I wiped the old drive to fill it with movies/music/pictures.
