Reinstall Linux, no bios


Hi,

I sm trying to reinstall linux from a usb stick, but I do not have the bios option. No F2, F12 or DEL. It starts with a black screen and it enters directly in mint logo. If I press F2, the logo dissapears. after a while, 10 minutes, I am able to see the screen and to introduce the user and the password. if I introduce them, it's black screen all the way.

I have a Toshiba Satellite L750.
Previously, I was running Mint Ubuntu.
It boots from the hdd and I want to boot it from the usb.

Everything was working fine, until my laptop ran out of battery and shuted. After that, the bluetooth didn't work at all. I tried different commands, did not work, and then I uninstalled the bluetooth . I restarted the system and the black screen problem appeared suddently. I was able to enter bios until now, suddently.



Sorry if I have grammar mistakes, not my primary language.

And thanks for your help and your time,

It seems you need to get back into BIOS using something like hitting <del> repeatedly -- search for your how to get to BIOS for your particular board.

Until now it was F2 or F12, and it worked.
I've tried and no, if I hit repeatedly f2, i will enter a black screen with a command prompt and everything i type it appears like '[[262' or something like that - random numbers.

now i am in the recovering menu.
in the system summary, it appears that 'no raid system detected'.

I will try to find a command from the root shell, maybe i can enter bios that way.

That is not anything that Linux can help with.
I suggest a search of your BIOS type and key, or something like that. As I mentioned <del> is common but I think <esc> may also be used, along with others.
What type of machine is this though and does it have a "reset" switch?

i found out a method on tomsguide
- pressing f2 and power button at the same time
- you will hear a continuously beep
- then, you have the f2/f12 option on the lower left side
- entering bios

i switched it to usb flash, let's see if it works



thanks, soadyheid
