Well looks Windows live always look at all disk because even from the install dvd I am landing on this screen 
Not only text does not appear but this menu 
is disabled for an unknow reason. Which prevent me starting chkdsk.
When I try to boot the real Windows 10, it freezes at the login screen so I can t do anything from there (F8 being disabled I cannot start in failsafe).
On linux, the drive is so corrupt that ntfs-3g fails to mount it read only (but the kernel driver works).
Because this is a hardware raid array which is enabled only when legacy boot is disabled (leaving only UEFI), I can t just take the drive into an other computer.
How to start cmd.exe in this situation given I can t even reinstall because of that screenshot?
