Doesn't your Lenovo laptop have what Lenovo call a '1 key recovery' button?

It is a very small button located near (in my case) the power in cable. You need something like a paper clip to press it.
You press it while the laptop is powered off & it will then immediately automatically boot into the BIOS screen..

More likely the BIOS is interfering. Is this a new install? Which Lenovo? Some are set to a RAID only single drive mode, and no AHCI mode.

Instead of pressing and holding f2 key, try tapping the f2 key.

I see the phoenix BIOS. However, the GRUB can't EVER interfere with the BIOS, since it gets passed off to by the BIOS, for bootloading the OS. If that laptop has a CMOS coin battery on mobo, like CR2032 in it, that's likely the problem and needs replacing.

I believe you're yet another victim of the Phoenix SecureCore Tiano UEFI bug which has installation of any OS in UEFI mode subsequently deny entry to the UEFI setup. There's many reports out there for G480 and G580 and we've seen the issue here on the forum before with other machines with that early UEFI BIOS version. Do you have Windows installed as a dual boot and can you still boot it? If yes, reflashing the BIOS from it will likely fix things again. If not... there's quite involved solutions out there such as https://forums.lenovo.com/t5/Lenovo-B-a ... -p/2133603

Seems thought that simply reinstalling Windows (if F12 still works and you can boot from a Windows install USB/DVD), reinstalling Windows, reinstalling Mint as dual boot and reflashing the BIOS from Windows would work. Or make sure to install Mint in legacy mode next time if you desperately don't want Windows sitting around a corner of your disk. Nut in any case, reflash first and that likely implies Windows first...

that's a good catch rene! I know Lenovo put out a special "Linux BIOS" not long ago, for some of their RAID only BIOS,after a battle in 2016 between Linux users and Microsoft/Lenovo changes that were done to how they were blocking out Linux on some new computers at that time.

Where you can read articles about that time.

This particular issue is a bona fide bug though: in previous iterations of this issue here on the forum I ran in to reports of this happening also with e.g. Windows 8 installed in UEFI mode on an original Windows 7 system. It's just that Linux is the by far most common first by the customer in UEFI-mode installed OS which has this look like anything to do with Linux as such...

Oh. I didn't even in fact read that linked "involved solution" thread beyond skimming the initial post, but note a bit below:

https://forums.lenovo.com/t5/Lenovo-B-a ... rue#M46868
Update: Even in the newest BIOS Update 62cn97ww (for Lenovo G580), Ubuntu causes the same problem. I came across a solution on the internet, that works without having to update the BIOS if Ubuntu can be accessed. To fix it, boot into Ubuntu (should be installed on the system), start Terminal and type in the following commands:

Code: Select all

sudo grub-install
sudo efibootmgr -b 0 -B
Reboot and F2 should work. BIOS should be accessible through F12>Tab>Setup also. Ubuntu will boot no more but can probably be fixed.

Notice even in 2008, odd stuff going on with Lenovo. This sounds like a CYA sort of answer. I for one will never buy a Lenovo.

All,

Thanks for alerting us to this issue. These BIOS updates apparently produced a very rare and unique side effect in which a random character power on password was set during the BIOS update. This occurred in less that 1% of systems, and as such was not found during pre-release testing.

Lenovo has temporarily removed these files from the web to update the code to address this issue and the files will be re-posted once the update is confirmed and re-tested to ensure no re-occurrence of this symptom.

For the majority of the population, the BIOS update proceeded smoothly without the noted issue with a Power on password being set. No further action is required for these customers as their systems should function normally.

For those who were affected, the Power on Password can be removed by removing the CMOS battery (the one that looks like a watch battery) from the system temporarily, and allowing the memory to drain. Reference the Hardware Maintenance Manual on the e-support site for your particular system if you feel comfortable performing this activity yourself.

At a high level, these are the steps to follow:

Turn off the computer.
Remove the battery pack.
Remove the backup battery
Turn on the computer and wait until the POST ends. After the POST ends, the password prompt does not appear. The POP has been removed.
Reinstall the backup battery and the battery pack.
Note: Some ThinkPad systems have the ability to reset the Power-on passwords in the ThinkPad BIOS setup utility if a Supervisor password has been set.


If you do not feel comfortable performing this activity, or if you are not able to successfully remove the power on password following those steps in the HMM, please contact service for assistance.

Well, if you'd vow to never use a technogy product once some customer somewhere at some time runs into a bug... you'd have a quiet life :)

Forgot where I got the command, either from another post on this forum or researching for something and got it in my notes. It is a 2015 added systemd feature, similar to how you can boot into firmware settings directly from Win10 with: hold shift-Restart, Troubleshoot-Advance Options-UEFI Firmware Settings.

As mentioned, you should now so as to regain access to your BIOS settings: you are being hit by a BIOS bug.
