boot sector damaged again

dennis

hy,

I'm trying to get kodi(xbmc) running for a few days now, but every time i'm almost ready and want to do a final reboot my boot sector brakes down.
I've tried to restore it several times with boot-repair without any luck.
Can someone please help me localise this problem and restore it because i'm going crazy here.
I've setup kodi to boot directly (without login).

I can see Marws has the same issue ( https://up-community.org/forum/public-ubilinux/968-start-in-shell-mode-because-ubilinux-not-found-anymore-after-unplug-power-supply )
