Windows 10: Windows 10 Upgrade C1900101-20017 Error

I'm having the same problem trying to upgrade to Windows 10. I also used Paragon software to clone an HDD to SSD, which other posters mentioned as well. So, I believe this is the primary contributing factor here.

When I attempt the upgrade, as some point I also get a rectangular popup message in the upper-right corner of the screen about alleged "problems on drive D:" and "running chkdsk", even though I have no drive D: on my machine. What really happens is that the update picks up hidden EFI partition on drive C: and for some reason assigns drive letter D: to it. This might be the actual reason for the failure. Immediately after the reboot (and the "SAFE_OS" message about the failure), I can actually see drive D: mapped to the EFI partition. It is visible in Explorer, even though it does not exist in Disk Manager. (The next reboot makes D: disappear for good).

Apparently, Paragon software HDD-to-SSD migration process does something incorrectly. This is what later makes Windows 10 updater incorrectly interpret EFI partition on system drive as some sort of "broken" D: drive. And this is what makes the update to fail.

In my case I just did a clean reinstall of Windows 8 on the target drive (deleting all C: partitions in the process) and then updated it to Windows 10. That way it went through without any issues.

 

I just wanted to come in here and post what wound up being my solution after months of trying to upgrade to W10.
I spent MONTHS trying to upgrade. It turned out to be my boot partition. Its usually called "System Reserved"( it ususallly wont show unless you are in disk management). On my machine it had been deleted when I incorrectly restored a system image to a new drive after a drive failure. Macrium startup repair fixed the machine after the restore so it would boot, but did not actually make a new boot partition. When I was first trying to install W10, the machine would not even boot. Just a black screen because W10 needed the boot partition. So, I created one, but after my C drive. So, my disk had C drive first, then the boot partition. After trying the upgrade, it would boot, but back to W7 with the C1900101-20017 error.... Months went by and I tried all of the suggestions...replaced my network card because old broadcom cards could cause the error and uninstalled many unused programs...still no dice on getting W10 to work. Then, I decided to move the boot partition to before the C drive partition and whammo, W10 installed without a hitch... TLDR version; make sure your boot partition (maybe called system reserved) is before your C drive. You have to look in disk management and the boot partition should be before(to the left) of the partition that contains your operating system...If it isnt, use a tool like mini tool partition wizard free to move teh boot partition to the left of the os

 

I am having the same problem but my SSD has a two more partitions. I will list them in order:

WINRE_DRV
SYSTEM_DRV
Local Disk
Windows8_OS

With my partitions in the above sequence, the SYSTEM_DRV is not directly adjacent to the Windows8_OS partition. I am curious how your partitions are layed out. I also used Paragon Hard Drive Manager to copy from a smaller SSD to a larger SSD. Any ideas would be appreciated.
