0xc0000034 error

my dell was running fine ,then dell backup &recovery popped up so i downloaded it, then it restarted

I have always x it out but stupidly decided to get it this time

i decided to remove restore points and make a new one, after i restarted computer which i have done before i got error code 0xc0000034 boot config data file missing some required info

i have done f2, f12, and another i cant remember . ran diagnostic , everything is ok , hit power 4 times on and off as per instructions, cannot boot into safe mode ,reset defaults in the blue screen that comes up when restarted and will not boot further

there is no way to get into restore or recover options ,

Anyone have this before

thanks
