Windows 10: Suddenly Going back to W7 while Installing W10

    Suddenly Going back to W7 while Installing W10

    I was installing W10 and got that black screen with the big white circle. Then, once it restarted. When it booted again, suddenly a screen came up saying "Attempting to Recover Installation" then saying "Restoring your previous version of Windows....". Why does this happen? Is there any way I can change where it boots into? Thank you.

    I am currently having the same issue. Initially, somewhere along the validating system for install, I was spit out an error that pretty much told me the install couldn't complete due to insufficient boot space on my Data Partition. The final time, the update completed all the way until boot up, were I was given the flag for "Hold on, we're setting up a few more things for you...", which resulted in this error:
    0x1900101-0x20017 The installation failed in SAFE_OS phase with an error during BOOT operation.
    Now, my fix for the first issue I had was going into Disk Management, creating a volume label for my data partition and running a chkdsk, as well as taking ownership of all files contained in this partition, AND adding readwrite admin privileges, which allowed me to minimize space.

    At first, I thought the volume label could perhaps be messing something up with the boot operation, but the more I think about it, the more I doubt myself, because I can successfully reboot into WIN7 afterwards. I've seen a list of possible variables that could cause this error, but aside from doing a clean install I haven't found any other fix, and the last post I found that actually had a solution for this wasn't even an upgrade, it was changing builds. Some people are saying computer drivers, other people are blaming Nvidia and claiming GPU drivers, which, I wouldn't NOT believe. It's getting a little tedious, having to continue through this process multiple times, only to bump into a new wall every time.

    NOTE: I do have a secondary drive (An old 1TB HDD), however, almost every one of my friends that have upgraded from win7 to win10 also have 2 disks, a primary SSD, and a backup HDD for storage, and their installs were simple and easy.

    Anyone have any assistance to get over this hurdle, and also, I hope the following advice on my first error fix (No credit goes to me; I was not the one to come up with this fix.) can provide you some assistance, @harvard.
