    Upgrade from 1607 to 1703, error 0xc1900104

    I read online it could indicate that the System Reserved partition ran out of space.

    Checking the file "C:\$WINDOWS.~BT\Sources\Panther\setupact.log" I found this line:
    2017-07-29 20:04:54, Info CONX CFreeSystemPartitionDiskSpaceChecker: checked InsufficientSystemPartitionDiskSpace, found HardBlock.Not enough space on partition [\\?\GLOBALROOT\Device\HarddiskVolume3\] Required: 15 MB. Available: 10 MB

    I managed to free ~100 MB, now it's marked as raw (unallocated space) and it is next to the SRP.
    I wish I could merge this space with the SRP but I don't know how to.
    As you can see the diskmgmt utility doesn't recognise the SRP while the diskpart program does (it's the 16MB partition marked as hidden, number 3).
    What should I do?
    Note: I can use Linux utilities but I would like to use Windows ones first if avaiable, I don't want to mess with my installations.
    Note: I am currently dual booting with Arch Linux using GRUB on the EFI partition. Arch Linux is installed on Volume 5 (I don't know why is marked as hidden and raw from diskpart and as recovery partition from diskmgmt).

    Good analysis: I generally recommend people have 500 Mb unallocated (it doesn't matter where) when upgrading or doing an in-place upgrade repair install.

    Both can result in there being two Win 10 Recovery partitions on disk (the unused one is not deleted - presumably in case of reversion- but it never is deleted automatically).

    Try shrinking C: that much.

    Diskmgmt doesn't show the 16Mb System partition by design. For that use a 3rd party tool.

    The file system of the partition is unknown on linux and Windows set it as "other", I didn't find any program that is able to expand it.

    Minitool Partition Wizard is very often mentioned here.

    I upgraded succesfully without touching the SRP, I followed the article in this thread.
