Windows 10: Uninstall Grub Bootloader in Kubuntu?

Hi, let me tell my story first:

I had created a dual boat about two months ago. Once Windows 10 and once Kali Linux. Then I tried to hack my own wlan. The wordlist I created should be 100 petabytes in size. I thought to myself: It will stop at some point. Conclusion: It partially did. When I restarted Kali Linux, it was extremely slow and there was no graphical interface. Since I couldn't find the wordlist with the terminal, I wanted to uninstall Kali Linux. So I watched some videos on Youtube how to do that. But for most of the videos the tools were no longer available. So with Windows 10 I deleted my Kali Linux partitions and restarted my laptop. After that I had an error from Grub that there are no partitions to boot. Then I took my boot stick and selected Kubunu ("to test" clicked, so I have some interface). So now I am in Kubunu and don't know what to do. When I try to boot with the Windows Boot Stick, there is also an error.

Question for all those who do not want to read through it: How do I uninstall Grub Bootloader with Kubunu?

Remove GRUB

This pretty much covers all scenarios:
boot - Uninstall Grub and use Windows bootloader - Ask Ubuntu

 

Grub bootloader before windows8

will the W10 upgrade work if you have a linux bootloader setup before the windows
bootloader ?

had some negative experience before, (8 pro >> 8.1 pro update) that messed up the upgrade then, got stuck at 80% and then told me nice that it "fails-to-install"
and rolled back to 8.

so are there any 10 testers (who have the same setup as me and) who can tell me if MS has a better upgrade method this time, last time i spend hours, had 2 fix the grub, because the w8.1
had deleted it and it kept upgrading a failing system in its own circles, like a crazy dog trailing its own tail.

so will this upgrade experience in my situation be better this time?

or do i
need to remove grub again ?

 

Make Windows 10 Bootloader Override Windows 7 Bootloader/GRUB

Now after running into two different grub errors, my PC refuses to boot from anything. First I got the grub error no such partition, so I booted from Ubuntu 17.10 install disk and reinstalled Ubuntu 17.10, removing the previous installation of Ubuntu 17.10. After resinstalling, I booted once, and grub appeared normally, I think I also booted into Windows 10 from grub and ever after that, I can no longer boot period. I get this:

GNU GRUB version 0.97 (593K lower / 523264K upper memory)
[ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ]

I've tried booting from Windows 7 & 10, Ubuntu 17.10, 18.04 & DBAN (hdd wipe) disks with no success. Now what? (trying the grub commands from this link:

How to recover lost GRUB bootloader in Linux

didn't work).
