Made a big mistake trying to get rid of partitions on Venue 8 Pro. OS will not load anymore!

Hello,

                  First time on this type of forum so I hope what I write makes sense.  So, here it goes.  I upgraded my Venue 8 Pro to Windows 10 and after the upgrade it kept telling me that I needed to make some space on the disk.  I looked and there were not many programs I could removed and so looked further and found that there were 2 partitions that had almost 6 gigs assigned to them that were not used.  I tried to reclaim that space.  I first did a recovery copy on the micro SD and that seemed to work fine.  I then fiddled around until I was able to remove the 5+ gb partition and reallocate it to the main partition.  The second partition (about 750mb) I was able to free up but as it was before the main partition I was not able to reclaim the space into the main partition.  I downloaded a recommended utility to try and move it after the main partition so I could reclaim it like the other one.  Everything seemed to work but then it came to a crashing halt and I got a blue Windows screen saying that "the application or operating system couldn't be loaded....".  I figured out how to get into the bios to see if I could change the boot order, I created a windows 10 bootable USB and after much work finally got the tablet to start from the USB.  At that point, Windows 10 wanted to re-install (which I am fine with) but the only problem is that the touch screen no longer responds!  I guess the driver is not loaded on a USB boot.

Now I am stomped.  I really don't know how to go any further.  Is there a way to get the drivers to load from the USB key?  Can I send my tablet to some magical place where qualified technicians will re-build it for me?

Any help or moral support would be greatly appreciated.

Thank you

Richard
