I did launch startup repair and it goes to black screen with white arrow, nothing else.
I tried to recover factory settings, and it said missing a file.
I pressed F8 and and did the start from last good config. Nothing also.
I did disable auto restart and blue screen gave me this:
unmountable boot volume stop: 0x000000ED (0XFFFFFA8004F575D0, OXFFFFFFFFC00000B5, 0X0000000000000000, 0X0000000000000000)
