Using UEFI

I have a Compaq CQ61-313US (see sig), and it does contain a UEFI BIOS.

 

However, it's missing the UEFI Boot Mode to even use a EFI based OS..  I have gone all over the BIOS and know for a fact it has the capability to do it, but HP just didn't put this option in the boot menu.

 

I contacted HP support but never really solved the problem.  It was forwarded to another tier, whom never even emailed me back, and now the laptop is out of warranty, and still nothing..

 

I really need to use the UEFI Boot Mode option for a specific OS I need to load on it..  Short of selling the laptop and getting another model, is there anything I can do?

Re: Using UEFI

HP is renowned for crippling their bios's, not sure what you can do if anything.

Re: Using UEFI

Hmm, hope not, because according to HP's UEFI site, this laptop is definitely supposed to have UEFI boot mode capabilities.

 

In other words, the laptop isn't working as it's supposed to be.  I foresee legal actions against HP for crippling a BIOS that they claim has a feature they deliberately disabled.

Re: Using UEFI

I think it does boot UEFI, when you run the hardware diagnostics from the bios it boots the UEFI, 

 

See this doument, it may give some insight.

Re: Using UEFI

The diagnostics is the only EFI application this laptop is seemingly capable of loading..

 

When you press F9 at boot, "Boot from EFI File" is completely missing, it's just simply not there..

Re: Using UEFI

The way it was explained to me was it will onlt boot from a volume named HP_TOOLS, so you would need to rename that partition on the hard drive to something else, then name your boot flash drive to HP_TOOLS, then it should boot to that volume when you select diagnostics

 

The PDF I linked to spells it out, there are certain guidelines you must follow, read carefully.

Re: Using UEFI

I have gone through the manual, for the past year and a half..  NOTHING works..

 

For one, if it's in HP_TOOLS, it must be an HP signed EFI file, so the OS I am trying to run as EFI won't work because it's not HP signed..

 

Then there's this page about loading non hp signed EFI apps: 

"If you want to launch non–HP-signed EFI applications for development purposes, follow these steps:
1. Access the Computer Setup utility and select System Configuration.
2. Select Device Configurations, select UEFI Boot Mode, and then select Enabled."

 

On this laptop, under Device Configurations, "UEFI Boot Mode" isn't there either..

 

I have contacted HP about this, and all they can tell me is yes, they did disable the ability to run an EFI OS, and no, they won't say why..  I've told them that this conflicts with their EFI documents and that it should be supported, they only say "Sorry"..  Nothing..

 

PS:  I have been in IT for many years, so EFI is nothing new to me..  This laptop just don't have the ability load EFI apps, and HP don't care about it, just because it bares the Compaq name on it (just because all HP laptops I've seen have the option to enable full UEFI, and no Compaq I have seen has it, despite using EFI for it's internal use.)

Re: Using UEFI

I wonder if their business line of Notebooks do have that ability.

Re: Using UEFI

Compaq business line?  No idea..

 

Thing is, according to UEFI docs from HP, all laptops after a certain year are supposed to have it, and this laptop definitely is supposed to have it..

 

To be honest, it seems Apple and IBM have the best support for EFI so far..  My next laptop might be an Apple (just because IBM themselves don't make laptops anymore, and I don't think Lenovo took the EFI support with them, but instead use Pheonix BIOS).

Re: Using UEFI

The current HP UEFI BIOS and the HP UEFI support are outdated, this may cause problems with "Complete crashed, Automatic Recovery Start, problems with Hibernate (standby mode), CPU goes to 100% on shutdown and freezes" this relates to the operating systems Windows 7 and 8 with UEFI support.

 

The only solution is:

 

The UEFI support in the BIOS (F10) to disable. enable the legacy support.

 

The system boots not so fast there is no more crashing!
