I changed failsafe option disabled too and even tho i choosed visibility as USER , i cant see option in bios.Cant flash it since usb not working and no other option avabile on my mobo (z270 pc mate) , maybe will not be able to reinstall windows at all didnt tried yet.
Any ideas 
?
Primary option, M-Flash and previous bios (factory or edited in another system, in one internal disk).
An external add-on USB card or you’re going to need restore factory bios, by CH341A programmer, direct SOIC8 contact, de-soldered form board or JSPI1 header… this model has no dual bios or usb bios flash back, so options are limited to programmer.
AMIBCP changes used in Aptio IV are not reflected in Aptio V bioses (Other modules like AMITSE etc… also needs changes), also we dont change the settings of a variable (most cases) we only change the visibility/access of the parent or sub-menus that are not visible, last if not visible, the string itself access.
You may try recent methods for Aptio V:

Thank you for your efforts, allocating a small fat32 partition on my only ssd seem to not working , putting another via sata will work i guess?
Doesnt see internal hdds?.. well i hadn’t any MSI Z270…but my current MSI Z490 M-Flash does browser all kind of drives, external or internal.
Do you think pcie usb card will work ?
It should…as its a device controller outside the motherboard chipset control, what else can i tell you.
I cant guess on several adapters/motherboards/bios utilities will react, to give you a confirm answer as may understand.
So your M-Flash cant see no drives besides USB??? Strange… but if you say so i wont insist on this subject.
No , dont have extra drive rn , but not seeing my main ssd yes.
Of course you couldnt guess ,its just im kinda broke rn , just checking before buying a card.
Dont meant to ask silly questions 
Thx again man
