"We couldn't install Windows 10. We've set your PC back to the way it was just before you started installing Windows 10. 0xC1900101 - 0x20017 The installation failed in the SAFE_OS phase with an error during BOOT operation"

I have tried all the remedies suggested from the initial problem that was Code 80240020, delete files, try again... never worked.

Thought the problem might have been my original set-up. An SSD as DISK1 that contains W8.1, and DISK0 had other drives including the original Dell W8.1 on it (hidden when the OS was running):



So I detached the other 2 drives:



DID NOT help?

Windows Update shows a variety of error for the failure as well.

I even tried the UPDATE tool...

No matter what I try I always fail and return to the W8.1 desktop?

Anyone have a FIX for this?

Hi IVRS,

This seems that it could be an issue with some installed applications?

Check here > [RESOLVED] Couldn't update to Windows 8.1 - 0xC1900101 - 0x40017

Well I read the link and although it is for a slightly different error (40017, not 20017) I did Method 2, the clean boot.

Failed as well...



I'm going to try the UPLOAD tool, but I don't expect any change... sigh...

I guess you missed it 'Z'...

Yes, I've got back-ups of both C:'s. Using Symantec System Restore 2013 (I hope this works on W10, it is expensive to get new versions for 3 systems). Others in the Dell forum with the problem have been able to Update the original C: but not the new one on the SSD, so it probably isn't h/w or s/w per se but how W10 sees the SSD I'd think.

I have NO desire to start over. That does work to the Original drive only.

I was thinking about doing a restore to the old C: with Symantec of the SSD C:, and give it a try. Even if it did work though, I'd then have to clone that over to the SSD, but I'd probably have problems with future updates then?

I do hope MS calls and can fix this so I'm hanging in there and waiting.

Other PC (L's) is also a Dell, but an XPS 8500, 2 years old. Dell does NOT say it was tested. It's failing under Windows Update as well, and it has a similar SSD setup. So I'm sure it is HOW the SSD was cloned over and made bootable. Only difference is L's PC I did it manually and had to do some under the cover type of disk editing as the clone (using Norton Ghost at the time) produced 2 identical disk ID's. Had to change one and then it booted fine. On my PC I used Paragon's Migrate SSD 4.0 and it worked like a charm.

If you search the web for my error some had it with the Preview as well, so I can't believe MS hasn't seen this before, even happened during the W8 to W8.1 updates. I was running the Preview, but in a VM and had no problems, but that does visualize the h/w so that is why it might have worked?

It will be interesting to see what MS has to say if they ever get back to you.

I suspect "Sorry, not our problem"!

In the Dell forum it turns out a few have the identical problem, all on SSD's as the boot drive.

L's XPS 8500 as it turned out DID install W10 to the SSD without a problem! Different Security Suite (Norton vs. McAfee on mine), Pro with Media Center and I have Home, different video cards, ATI vs. Nvidia, but basically the same systems. Hers installed without a hitch.

Fast forward to the Dell forum... and those of us with the problem all have it on SSD's. One tried installing W10 to the original hard drive and it worked. We all thought maybe the way was to cutomize W10 to what we want and then clone it over the SSD. Makes sense but that is a heck of a lot of work and lost things as well. As it turns out one person decided a better way. First installed W10 to the hard drive over W8.1 to see if it worked. Then cloned the SSD to the hard drive. Guess what, same fails. Even the W8.1 install disks fail like W10. Reported back in the forum and that is when we ALL discovered we used Paragon's Migrate OS to SSD 4.0 to clone the SSD. It did work well and it was easy, BUT something is did/changed has stopped Windows install in its tracks!!! I have no clue what that could be?

Posted to Paragon's forum and also to their support message area. Like I said, I can see MS telling me it is their problem.

So right now I'm in limbo. Hard drive is way out of date. Last used in April 2014. Many programs on it need to be updated and I'm not sure I want to do that now. Just MAYBE someone can fix this mess.

2 suggestions:

1. Disable your AV, uninstall Classic Shell, Start8, any Stardock software.
2. Redo the clone to the SSD using Macrium Reflect Free. Might even create a backup image then restore it to the SSD instead of clone.

A/V was active on the hard disk when I installed there, so it isn't a problem. No Stardock s/w.

I need the state the SSD is in. Could care less about the hard drive C:. All I did was populate it with things like Firefox, Thunderbird, Quicken 2014, and a few other things I'd want on the C: drive. Got the data for them off the old computer and then cloned it to SSD. I left the hard drive C: in case Dell wanted me to restore to the shipped state if I had a h/w problem. They usually ask for that at first.

What I need is the SSD brought up to W10. What ever happened migrating to the SSD will still be there possibly. I could have the problem in the future as well. The fix I need is to be able to INSTALL to the SSD...

The hard disk W10 is a pain right now. A lot of things need to be updated and background tasks seem to be running doing the same, updating almost everything that calls home to see if there is a newer version.

I'll at least wait for MS or Paragon to give me an answer and go from there. I might be forced to update the hard drive to where I want it to be and then clone it over to the SSD. It will not be a fast or fun job....

Did you mean inactive? If not disable and try again.

So you can't re-do the clone from the HDD to the SSD?

No, Active. W10 installed fine on the hard disk's C: partition with McAfee in full operation.

Problem is getting the present SSD C: on the hard disks C: partition and THEN upgrading to W10. One person tried and W10 couldn't be installed and failed. It is possible I can use the Image vs. cloning, but right now I'll see if Paragon or MS has an answer.
