Once more, UEFI difficulties with my HP Laptop... regarding windows...

Well, sometimes life makes you go down a path you didn't think you'll visit again.
I'm supposed to start very soon a course that will deal with many intriguing issues
but will begin with aspects of Windows.... so I found myself reinstalling windows 10
on my laptop, and running to the old UEFI issues of incompatibility of my HP Pavilion 14...
Neither Windows 10 or 8.1 nor Linux mint or Fedora were able to solve the problem this time...
and thus I found myself trying again and again, using various solutions I and software tools
I found on the net... nothing worked, and frequently it seemed that a certain inconsistency
of the laptop would drive my mad - it would not able booting into anything, unless legacy mode
enabled, but when legacy mode was enabled, no solution to fix the lacking EFI data on disk worked....
at the end, I was able to boot into a USB based windows installation (made with the RUFUS tool) and use a set of commands I found on superuser.com regarding UEFI & windows booting difficulties to form my own solution for my problem:
diskpart
sel disk 0
list partition
[do what it takes to make an EFI partition. 
search "create partition efi" if you don't find it elsewhere, on the link below ] 
list volumes
select volume XX
assign letter=b:
exit
bootrec /fixboot
[ make sure to verify what goes on in your b: drive; mine was empty, and therefore did not need to backup, and could immeditely:  ]
bcdboot XX:\Windows /l en-gb /s b: /f ALL
(i think the f ALL did the trick in my case) 

reboot... and the computer is booting into windows 10... next step (which I hope will not be that horrid now),
is to make it into a dual boot machine... keeping my fingers crossed this will not turn into an all-nighter...

If you happen to experience an occasional performance issue on your computer ever since you've installed that android emulator...

The family salon computer was hanging. A relatively powerful windows 7 machine.
I could not access "my computer". But I had access to drives.
I checked the processes. 
A process called "HD-PLUS" something was hogging the cpu.

I tried searching the net, and hopa!
Turns out it is a process of the Bluestacks emulator

Yes.... i am one of those who have installed it. Because of the kid. He wanted to play some Android game, and it seemed logic to try and see how is life with android emulators. Bluestacks wasn't fast enough, so we moved on to NOX (which is, at least for now, as far as performance and ease of use go, amazing). But as there was no obvious reason to remove bluestacks, I left it to be. 

After all, if it isn't running, assuming the software in itself is safe, why not leave it for trials when time allows?

But there you go.
Even though it was officially not running, it was hogging the system... 
so I removed the software. and everything returned back to normal.

Conclusion: if you have a performance issue on your computer ever since you've installed that android emulator...
