Bios Update F.10 affects UEFI OS Boot Manager (Paviliion 15 cs-3xxx series)

[Anonymous]

After upgrading from Bios F.06 to F.10 I encountered two issues.

1.  On the UEFI BIOS menu, for OS Boot Loader, only the Windows boot loader shows whereas I had two boot items in F.062. In Linux (I know, not supported), if I had Legacy Support Disabled, I had no audio. Had to enable it to get audio.

But the important matter is that I have no access to any boot item other than Windows after the BIOS upgrade. The workaround for me is to boot using EFI and select the Slackware (in my case) UEFI Directory and boot directly. I am not satisfied with F.10.

(ignore tje bootx64 file. It was a test)

Question: Is it safe to roll back to F.06 and will UEFI work as before?

Thank you

As a follow-up, ROLLBACK is not possible as an error is reported "Unable to locate .SIG file". Apparently, the UEFI security enhancement requires one., F.10 package has one, F.06 does not.

If the issue persists, after the above steps, try the below:

1. Turn off the notebook.

2. Plug the notebook into a power source using the power adapter.

3. With the notebook off, press and hold the Windows logo key  and the B key at the same time.

      NOTE:

   On some notebook models, it might be necessary to press and hold the Windows logo key  and the V key.

4. While pressing those keys, press and hold the Power button on the computer for 2 to 3 seconds, and then release the Power button but continue to hold the Windows logo key  and the B or V key until the HP BIOS update screen displays or you hear a beeping sound (usually 8 beeps).

   The HP BIOS Update screen displays, and the BIOS update begins automatically. This might take several minutes, and you might hear additional beeping sounds.

   • If the HP BIOS Update screen does not display, repeat the previous steps. If the issue persists after repeating the steps, skip to the next step to Download a replacement BIOS file.

   • If the Power light turns off, the notebook has turned off because the Power button was held too long. Repeat the previous steps, making sure to hold the Power button for 2 to 3 seconds only.

Thanks @Riddle_Decipher , but the F.10 BIOS installed properly and I suppose functions as designed (albeit poorly). It just does not function as F.06 does. The UEFI OS Boot Manager Bios Option only shows the Windows Boot Manager, none other. Unable to Roll Back (see above). I suppose I could always put an alternate bootx64.efi file (such as grub or lilo) in the EFI\Boot directory (Did bootx64.efi change with the recent update?). Easier option would just to roll back. I don't need UEFI security as this is a home laptop, not a corporate one. The inability to roll back is serious.

And PS: Taking the bottom off this laptop to remove the battery means destroying the four footpads which are glued on. I'm not sure I want to do that unless I was adding or removing other hardware.

2) Click on Sign-in or select the product using the below step:

3) Enter the serial of your device.

4) Select the country from the drop-down.

5) Click on "Show Options".

Fill the web-form, to populate a case number and phone number for yourself!

Also, if you are having trouble navigating through the above options, it's most likely because the device is out of warranty, if yes? please send me a private message with the region you are contacting us from,

@Riddle_Decipher

1. I did contact support. No response after hour long chat

2. Device only two months old and in warranty

3. Only want to toll back bios or have boot menu restored.

@Anonymous As I mentioned earlier, if the steps suggested to reset BIOS didn't work, it's most likely a hardware malfunction, and if you have trouble reaching out to the support chat/phone, here's an alternative:

If you have an HP authorized service center near by, you should be able to take it to them and have it checked,

@Riddle_Decipher, no it is not a hardware failure. The BIOS installed normally and the system functions. HOWEVER, the error is in the BIOS firmware where it does not permit a rollback or show all EFI bootable directories as F.06 did. your UEFI menu options show a ROLLBACK option. It does not work. This needs to be fixed. You shall see, I won't be the only one with the issue.

@Anonymous I understand your concern, however, the firmware isn't available as of now, the bios recovery isn't working for you and the only other way to fix this, is to get HP to repair the device, if you wish to get it done, please contact the support team.

I wish you good luck, ahead.

The solution appears to be this. The UEFI update overwrote the EFI firmware which contains the boot order entries. In Linux, there are two commands that can show the UEFI firmware settings outside of using the BIOS Firmware update. The simpler one is efibootmgr.

bash-4.3# efibootmgr
Timeout: 0 seconds
BootOrder: 0001,2001,3001,2002,2004,0000   (Missing boot entries)
Boot0000* Internal Hard Drive - TOSHIBA MQ04ABF100   (Legacy boot)
Boot0001* Windows Boot Manager   (Default boot)
Boot2001* EFI USB Device
Boot3001* Internal Hard Disk or Solid State Disk

efibootmgr permits the manipulation of the EFI tables. Here you can see the boot order is Windows, USB, regular HD. HOWEVER, you can see the BootOrder entries for 2002, 2004, are missing. I believe the old boot order in the previous UEFI version is my missing Linux boot.

So again, the BIOS UPDATE to version F.10 overwrote and did not preserve UEFI settings. I will now experiment with restoring boot functionality and will report back my results here.

The source code is located in the RedHat repo. https://github.com/rhboot/efibootmgr

A GUI boot manager is rEFInd. It's source is here: https://sourceforge.net/projects/refind/

A Windows application for this is EasyUEFI: https://www.easyuefi.com/index-us.html
