    4th update


    If I use MiniTool, I can create the 350 MB unallocated space on the C drive and move it to the front. However, when I try to extend the 100MB system partition (aka Partition 2 in Diskpart), it only allows taking from the 1GB recovery partition (aka Partition 1 in Diskpart). There are no other choices in the drop-down box.

    If I use AOMEI Partition Assistant, I can create the 350 MB unallocated space on the C drive and move it to the front. However, when I try to resize the 100MB system partition (aka Partition 2 in Diskpart), there's no room to drag the bar to increase the size of the partition beyond the existing100MB size.

    One thing I noticed... Both MiniTool and AOMEI show the 128MB partition (aka, partition 3 in Diskpart) located between the c drive and the 100MB reserved partition (windows disk management doesn't show this).

    The 350MB unallocated space is located between c drive and the 128 MB partition (aka, partition 3 in Diskpart); it's not next to the 100MB reserved partition.

    Maybe this is why I can't extend the 100MB reserved partition...

    This shows the location of the unallocated 350MB relative to c drive, the 128MB partition and the 100MB reserved partition.

    Yep, so you will have to use Partition Wizard to move the 128 mb partition over, so the free space moves next to the 100mb reserved partition, then you can extend it.

    The only options when I right click the 128 MB partition are delete, copy, surface test, wipe partition and properties. I can't move it.

    I can copy the 100 MB system partition to the unallocated 350MB space and then extend the 100MB to the full 350MB size. I can then delete the original 100MB partition, but do you think that will cause problems?

    Copy the partition to the empty space, expand it to 350mb, make sure to set the new copy as the active partition, reboot and try to do the upgrade. If the upgrade goes through, you will be able to reverse the process - shrink the copy back to 100 mb, copy it back to the original location, make sure it is set as the active partition, then expand you C: drive back.

    And it's still the same problem and same solution.

    And there is an alternative solution. Delete the 100mb EFI system partition and use a boot loader fix method to create the boot files on C: drive.
    Did you actually do this ? and what is "a boot loader fix method" ? Would you elaborate this.

    Copy the partition to the empty space, expand it to 350mb, make sure to set the new copy as the active partition
    Again, How do you set the new copy active partition ? Using diskpart ?

    Yes. My laptop currently has 2 partitions only on it. One partition has Windows 10 build 10240 and contains my boot loader files. The second partition contains Windows 10 Insider build 10532. I deleted the little 350mb system reserved partition that previously contained my boot loader files and used Macrium Reflect boot fix utility to create the boot files on my Windows partition.

    There are plenty of methods to fix a missing boot loader. There's the repair option when booting from Windows install media, there's a bootrec command, there's a bcdedit command, and Macrium Reflect has a tool to fix Windows boot problems, just to name a few. My easiest and most reliable method has proved to be Macrium Reflect.

    There's several methods to do that as well. I believe Macrium Reflect does it, if need be, when fixing boot problems with Windows. Diskpart can be used. Windows disk management can be used. Any partitioning program such as Minitool Partition Wizard can do it.

    You have to remember - just because a bios may not require the use of an active and separate "system reserved" partition to boot, the manufacturer of the computer system may still have used that method and that is what Windows 10 is seeing - a system reserved partition with the active flag set that contains the boot loader files. And if that partition is initially 100mb in size (which is the common pre-Win 10 size) and Windows 10 can't increase it's size to at least 350mb because something else on the disk is in the way and unmovable, then it will give the "can't update system reserved partition" error.

    Because of the differences in bios and computer configurations, Windows 10 is not going to change the location of the boot files or booting method during an upgrade - just like the rest of the previous operating system, it is only going to attempt to upgrade what is already existing. Now, you do a clean install and Windows 10 will create what it thinks the computer is configured to use for booting (which sometimes is not correct).

    Rittercon can certainly do a whole bunch of disk partition cleanup - his/her configuration would drive me nuts - but the object here is just to get an upgrade to Windows 10 to finish.

    Have everything pending and ready to go, except making the new 360MB "active". Don't see any choices in MiniTool available to do this.
    Will this be done automatically?
