    Need help, upon turning my laptop on it immediately shows a black screen with a blinking underscore and get stuck there. I've tried removing the battery and plugin it back again (which I've read in the some forums) and it still stays the same.

    It happened when I was replacing windows 10 whit Unbutu, I have only got into Bios from windows, not by pressing any keys.It wont boot from my pendrive or DVD i can do nothing. Before it happened i had changed the boot from UFEI to CSM so I could boot from my pendrive.

    I can't get in to the BIOS whit F2 or F12 or other any key. I have tried everything.

    My Laptop is a Toshiba Satellite P855-S5102
