Can I use silicone to protect the BIOS

I plan to create an airgapped laptop with a seperate bootloader that is on a permanently write protected SD card that i will cary on my pocket all the time.

I will also remove the wireless card on the motheboard. Only thing that makes me unsettled is the BIOS. It’s a pretty old BIOS and doesn’t even support UEFI.

I can’t be sure about it’s integrity so I thought can’t I just pour silicone to protect the BIOS chip? To prevent flashing new firmware I can just use a hard password.

Unable to enter into BIOS setup

I have hp-n003tx laptop. Recently I have changed my 1TB HDD to 1TB SSD(crucial company) and removed optical drive and connected HDD in that place. I have windows installed on my SSD. Few days back I have installed Ubuntu on HDD. Now every time I switch on my system I am taken directly to windows. And I wanted to enter into Ubuntu by turning off secureboot. For that I tried pressing esc key and it took me to all option which has boot option and BIOS setup. f9 is key for boot option and f10 for BIOS setup. Now I wanted to turn off my secure boot option. When I press f10 (key for BIOS setup) it doesn’t enter into BIOS setup instead it will be in the same page but if I press f9 (boot option) it gave me all the boot option. Please suggest some solution to go into BIOS setup to turnoff secureboot. Thanks.

Ubunutu BIOS bug

About a year ago (give or take) I bricked a Lenovo Flex 3-1130 laptop after installing ubuntu and got hit by the annoying BIOS bug. Couldn’t boot anything, even though the options to do so were there through the BIOS (ubuntu, windows, EFI usb, etc) but nothing booted. The Lenovo logo comes up for a few seconds, then the computer shuts off, then the cycle repeats ad infinitum.

Decided I didn’t want to deal with it until this week when I found out a solution came out. However, said solution requires being able to boot into an OS, which I can’t. I’ve scoured the webs and tried the following:

Removing the battery and trying to boot using AC power only.

Changing the BIOS settings to disable Secure Boot (surprise, I can’t).

Trying to reflash the BIOS using a USB (Downloaded BIOS from Lenovo, copying the .bin file onto the USB, pressing Fn + R at powerup to flash)

A caveat with the flashing approach: I used some tool (Adam P’s SLIC tool) to try and get the “recovery name” in the Lenovo BIOS image, but it wouldn’t work. I tried using a number of different names (AA.bin, BB.bin, BBHW.bin, etc, etc.)

Nothing seems to work. Not sure if maybe I tried one of the above approaches incorrectly. I’m a complete newbie at all this so apologies if I’m using some terms incorrectly. Any helpful tips on what to do next would be great. Thanks to you all in advance.

ACPI BIOS Error(bug) with file lost

I am using Ubuntu 18.04 but recently faced wired problem.

After complete shutdown, next day after start sometime got this error.

enter image description here

Then manually invoking fsck /dev/sdb2 solve the problem but every time there was missing something or some file. One occurrence I found that my home was deleted. Another time some binary was missing.

I do a fresh Ubuntu 18.04 installation that also doesn’t help either.

I suspect that my SSD may be corrupted but according to smartctl -a it’s OK.

ACPI BIOS Error and Ubuntu Freezing 18.04.3

I keep getting this error when Ubuntu boots ACPI BIOS Error (bug): Failure Creating [\_SB.PCI0.XHC.RHUB.SS10. AE_ALREADY_EXISTS (20181213/dswload2-324 Then if I click on settings or Mozilla it will freeze and I have to reboot the computer. I read somewhere this could be due to my NVIDIA GeForce Drivers. Here are my computer specs: HP Omen Laptop Processor- Intel Core i7-8750H BIOS Version- AMI F.05 Graphics Card- NVIDIA GeForce GTX 1050

If anymore information is needed just let me know

Bios stopped recognizing any drives after trying to install Ubuntu from usb drive

I tried installing Ubuntu (dual-boot with Windows 10) from my USB drive but I got the error “No EFI system partition was found, the system will likely not be able to boot successfully and the installation may fail” I closed the installer and reboot my computer to find that none of my drives are being recognized by the bios. When I went back to Ubuntu on my USB (apparently it can recognize the USB and nothing else) all the drives were recognized and there was nothing wrong with them. I have no clue what could be going on here.
