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).

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 ?
