Does BIOS do anything when the Computer is shut down

So, I start my computer. BIOS does POST, it boots the system, and from then on out works as a gateway between the OS and hardware, if I understood it all corectly.

If I now turn off the computer either by pressing the out button or by shutdown /s or anything like that, what does BIOS do.

Is BIOS involved in the shutdown process and does it do anything essential?


Unable to modify BIOS. Unable to boot USB

I used to have dual boot system: Ubuntu and Windows. Recently, something wrong happend to my Ubuntu. I tried to fixed, but nothing helped. I tried to boot usb with Ubuntu, but turns out that I have common problem with my laptop. So i tried to delete all, wich connected to Ubuntu. I formatted the disk with linux. Tried to delete folder with ubunru in EFI folder (but it still can’t be deleted). I tried to restore my Windows, reinstall Ubuntu different ways (throw USB, throw Windows). I tried to reinstall Windows.

So right now I have working Windows, but I can’t change BIOS and install new OS. Can somedy me to work out this?

What bios passwords & settings are important to set on a Thinkpad X1 laptop?

I am just booting my new X1 for the first time, and went into the bios to set a bios password. I discovered a slew of security settings:

  1. Supervisor password
  2. Lock UEFI BIOS Settings (enabled/disabled)
  3. Password at Unattended Boot (enabled/disabled)
  4. Password at Restart (enabled/disabled)
  5. Password at Boot Device List (enabled/disabled)
  6. Password Count Exceeded Erro (enabled/disabled)
  7. Set Minimum Length (integer)
  8. Power-On Password
  9. Hard Disk1 Password (text field, need to choose “User” or “User+Master”)

So – I have the option of typing 3 distinct bios passwords (not including the OS password), and enabling or disabling it at various points in the boot cycle.

What’s a good, secure setup to use that’s still convenient? Why do I need 3 distinct BIOS passwords? Which of the checkpoints should be put on enabled ?

Also – I intend to enable full disk encryption using Bitlocker. Does it make some of these options reduntant?

Grub but no bios

I have an intel compute stick that came with ubuntu 14.04, and I’m trying to access the bios so I can boot into a usb. The problem is that when pressing f2, f7, or f10 none of them lead into the bios and instead go into grub. How can I access the bios from grub or boot into a usb from grub?

GRUB locked bios help please

When installing Linux, everything went fine until I restarted to go back to windows. GNU GRUB came up and didn’t let me boot to windows. I tried resetting the computer and going to the bios to change boot order. But when I do that everything is locked up and I can’t change anything in it. The only way to get to windows is by going through Linux bootloader first.

How do I remove Linux, GRUB and everything from that so I can boot to windows and access my BIOS again.

Can’t find UEFI boot option in BIOS

I am using an old machine which has Intel i5-2410M processor 2nd generation.

I am planning to do clean installation of Windows 10 in UEFI as recommended by Microsoft on a recently purchased SSD. I have already created a bootable Windows 10 USB using Rufus with target system as UEFI, however, I am not sure if this bootable usb will work with my machine as I am not able to find UEFI in BIOS. I also intend to install Ubuntu in a separate partition.

Can anyone help me how to set firmware settings as UEFI before proceeding with this installation?

This is the detail of the motherboard:
