Greetings everybody. I have a problem with my Windows installation on my tablet which I don't know how to fix but have a feeling it's something obvious which I missed. So here's the story:

 

The problem

I recently bought a Modecom FreeTAB 8010 x86 tablet and it was all fine and dandy for the first few days but eventually I started running out of space on the system drive. I noticed that a huge portion of my internal memory was used up by the recovery partition (almost 6gb). In order to try to make the best use of the already measly 16gb SSD that's inside the tablet, I opened partition wizard from Hiren's boot CD and marked the recovery partition for deletion. Everything was set up and ready to be deleted so I told recovery wizard to restart the system and do the procedure. Windows shut down normally and after a short UEFI boot screen, windows started booting again but this time instead of the usual 10-15 second boot time, it took it almost 2 minutes and it didn't even boot. After around two minutes it crashed with a BSOD and a message saying: "CRITICAL_SERVICE_FAILED". Note that it probably didn't collect any error info since the screen shows up only for barely 3 seconds after restarting again and going in a bootloop.

How i tried to fix it

I first tried to boot into a live linux pen drive but couldn't since this tablet's motherboard doesn't support BIOS at all, no legacy mode, no nothing - it's UEFI only.

Since it was UEFI only I was searching for an UEFI compatible rescue distro and eventually just burned Ubuntu 14.04 iso to a pen drive. It didn't boot.

In a desperate attempt to even see what was the situation with the disk, I downloaded the untouched Windows 8.1 iso from Microsoft and burned that to a pen drive and suprisingly that worked fine and I managed to enter windows installation. From there I entered the system repair options. Of course none of them helped. It's not necessary to get into detail about this but the first two "system refresh" options didn't work since they required me to boot into recovery from the original working system. Startup recovery didn't do jack and I tried the usual /fixmbr and /rebuildbcd which also didn't work since this is an UEFI based system not BIOS one. NOTE: I checked the disk with diskpart and the original Windows and recovery partitions were still there, everything seemed to be fine. I eventually tried to go into safe mode but it also crashed every time I tried so that option is out. I then remembered that I backed up my recovery partition to a pen drive. "This is my way out!" I thought but it wasn't. Booting into recovery didn't help at all, you can see why in this video:

 

Closure

So this is why I come to you guys. Something has gone wrong but I have no idea why. Reinstalling is pretty much not an option since I wasn't provided with a serial key upon buying this tablet and I don't even know what internal devices it uses so finding the drivers would be a gigantic pain. If I missed some important information about the tablet or the installation please point it out to me and I'll add it. Also you don't need to tell me that deleting the recovery partition was an intensely stupid idea since I later found out myself that Windows used it to store compressed parts of the system on it and deleting it would pretty much render the entire installation useless. Any help on this issue is very appriciated and big thanks to everybody who takes their time to assist me on this issue.

 

EDIT: I have a feeling this thread didn't go into the right subforum (Should I have put it into the Windows 8 section?) If I did actually miss the subforum then I'm sorry, I couldn't make up my mind which sub forum was more relevant to my issue.
