At day 1 i got update bios, n everything by is ok.

At second days, im update my driver win7, n everything is ok.

At 4 day, everything is normal but when im shutting down my win7 n planning to change to linux mint 18.3 suddenly no BIOS NO LOGO
(Im change someting in easyBCD about safaboot, i dont remember about the details)
Unfortunately, my display is stuck in blank screen.


I ve tried hard reset, clear cmos battery, removing ram, unplug n replugged my DISPLAY cable, but still no luck.

Try to remove my hdd n cd rom too, but still no luck.
Cant go to BIOS,

Ive tried recovery bios, but with my condition, it was impossible.

I got my bios exe
From original 62cn41ww to 62cn44ww

N got bios bin too

Dont have vga cable to try another monitor, n another keyboard

Only have my android xiaomi redmi 5a, looking for another issue.
