Windows 10: Windows 10 B. 10586 Stuck on "Finalizing Your Settings"

Yo! I'm writing this before having to do a complete wipeout of my system

Specs:
Lenovo Y510p
Hybrid HDD (Seagate) 1TB
m.2 SSD (Trascend) 256GB.

Story so far (Jump this in case you don't want to know the background):

So, since build 9841 I've been using Windows 10 Insider Preview (IP) as my mainly driver. Until the recent redstone builds, Visual Studio has been plagued with problems (From Windows Universal Apps Development to ASP.NET) . I've installed Windows 10 IP in the SSD and have been using it very happily since I've had no major issues, until the ones I've outlined before.

In my Hybrid HDD I had Windows 10 RTM (10586) installed and didn't use it for a quite while (3 months). When these problems rose, I decided to start using that partition again, but out of the blue it decided to start giving me some serious problems: mostly, the whole XAML interface (Start, Volumen, Sound, Battery, etc.) didn't show up. After trying some fixes (From reinstalling Windows Apps to Creating a separate user), I decide to refresh the bits. Unfortunately, even after refreshing my machine didn't fix the XAML interface problems and even worse: I got no possibility to run Universal Apps.

I went and ran some hard disk checkups, from both: the Lenovo Utility and CheckDisk and none threw an error.

The actual problem:
Yesterday (Feb. 4) I decide to clean install Windows 10 Build 10586 64-bit in the Hybrid HDD partition (without deleting the OEM reserved spaces) and I'm stuck now on Finalizing the settings. Is there a way to fix it? Tried hitting Shift + F10, but in that specific screen it does not work. In previous screens there are no anomalies.

As last resort I must wipe out everything in both drives and start from zero. I would not like to do that, since Visual Studio is so painful to install (takes too darned long).

Is there a way to resort to an alternate method?

Thanks!

:)

Upon N97 Mini map data could be stored upon either mass memory or memory card with choice available within Nokia Maps application > Settings. Don't want you removing map data unnecessarily but you may possibly need to delete both E:\cities and F:\cities
+ .qf file and re-start Nokia Maps application to re-define necessary folder structure; it may help to set Nokia Maps "Online" and download a few kb's of map data via WLAN access point by zooming in to your current location and start again downloading maps
to chosen destination.

Almost certainly as not enough free phone memory to store maps.

 

Well then. It's not that I wanted to do that... I ended up wiping both Windows Installations. I'm back on RTM. What I can guess is that the OEM reserved partition got corrupted somehow and broke the Other OS.

Anyways, will install Insider Preview when things are going better.
