B590 - Can't access BIOS anymore

I have a huge problem with a B590 Notebook:

 

I replaced the harddisk for a test installation of windows 10. This was already quite a pain in the youknowwhat, since it didn't want to boot from USB-stick. I was able to solve that by changing a boot-option in the BIOS to 'legacy' and changing the boot-order and could continue with the windows 10-installation.

 

Then I wanted to reinstall the old harddrive and run the original windows 8 again. Unfortunately the computer doesn't seem to recognize the original harddrive a boot-device anymore. Instead it seems to search for a boot-device on the network (in an endless loop).

The problem now is, that I can't access the BIOS anymore. Pressing F1 as stated on the boot screen has no effect (just like pressing F2, F10, F12, ESC, Enter, AnyKey).

My next idea was entering the BIOS from the still running windows 10 installation (By pressing Shift+Restartbutton.) Strangely there is no 'UEFI Firmware settings'-option

 

So how can I enter the BIOS to check the boot-settings/order on this notebook?

 

Thanks!

Re: B590 - Can't access BIOS anymore

Me again

 

I think I found some more information that is relevant for this problem:

 

As I wrote above, to enable booting from USB stick I had to change the boot-mode to 'legacy'.  This caused windows 10 to install itself without UEFI-support and that's why there is not 'UEFI firmware' option in the advanced restart menu anymore. The notebook now simply acts like it doesn't have UEFI anymore. (Meanwhile I tried to install the tool 'EasyUEFI' which also says that there's no UEFI available).

 

The next problem with the legacy-bootmode is, that the notebook won't boot an OS which was installed on a harddisk with GPT instead of MBR. That's why it refuses to boot the original windows 8 from the original harddisk.

 

I still need a way to enter the BIOS desperately! For some odd reason it seems to NOT be possible by pressing F1 during the boot process. Maybe some Lenovo technician 'forgot' to implement that?... In this case I see two possible options that I could try:

1.) Remove the batteries to reset the settings and hope that they are reset to such values that enable booting from the original harddisk

2.) Install Windows 8 on another disk, flash the BIOS-update from the Lenovo website and hope that this one contains the 'forgotten' BIOS-key-option.

 

To be honest, I don't want to try any of those two options before some Lenovo-technician advises me to do so.

Any third option? Anybody?

Hi Zzap , 

 

Greetings. 

 

You can try to power drain it initially by removing the battery , ac adapter and harddrive ,then press down the power button for 12 seconds while off. Then without the harddrive to press on F1. 

 

If same issue ,herewith are similar discussions regarding the same issue that you can take time to review for the next action plan. 

Can not enter in BIOS Lenovo B590

Update us how things go.

Re: B590 - Can't access BIOS anymore

Hello,

 

sorry for the longer delay.

 

I knew the first link already, but that one didn't help.

However, the second link was new to me. The one advice (disabled 'Setup'-item in the boot priority list) was not applicable, since that item was not present in my list.

But encouraged from one of the other posts I tried removing the batteries to see what happens. After booting I got a message that the clock is wrong and I automatically landed in the BIOS. There I was able to change the boot-priority and now everything works correctly again!

 

I could even enable booting from USB-device AND from the original internal HD. If I remember correctly, one has to allow booting from UEFI and from legacy-device and set the USB-devices at the top of the boot priority list. (I don't have the notebook here anymore since it wasn't my own)

 

So if anybody is faced with the same problem of not being able to enter BIOS anymore: removing both batteries helped in my case and did not cause any further problem.

 

Thank you for pointing me to the above thread!
