Cannot get into Normal Bios on the 750-124 Envy

[Maxxpsoft]

I am talking about normal Bios and not the UEFI. I recently updated to Win 10 anniversary

Seen an upgrade to my Bios http://support.hp.com/my-en/drivers/selfservice/hp-envy-750-100-desktop-pc-series/8499646/model/8819...

which was A0.16 Rev.A.

Installed it and it reset my settings. I need to get back in there to turn back on my Virtual Technology. Otherwise I can only create 32 bit VM's in VirtualBox

Cannot get back in to normal Bios. I tried Tap the ESC which worked before, screen hangs and I hit enter and the HP logo comes up, tried hitting and also tapping F10. All these as I turn power on. I have a Logitech K800 wireless keyboard which worked before. I have tried a plain usb keyboard making sure they were on the USB 2.0 port. F2 will bring up the UEFI bios from a cold boot.

Them Win 10 things don't get me there Settings, Recovery, Advanced. Tried all of them

I was hoping HP had fixed the getting into Bios thing with that Bios update so installed it. This thing has been a pain as far as that otherwise I'd be a happy camper with this PC, how come you can't fix this HP?

BIOS and Windows 10 are very different things. You have a UEFI BIOS, not "normal", as you call it. I suspect you may mean what is called a legacy BIOS. You cannot access legacy BIOS because it is not present in your desktop PC.

BIOS is firmware and an operating system is software.

If this issue in getting to the startup menu happened after you updated the BIOS, then I suggest that you enter the PC UEFI Diagnostics  menu (with the F2 key) and use the Firmware Management section to rollback to a previous BIOS.

Haven't tried that cause at the bottom of the Bios update it states this

** After this BIOS update has been installed, previous BIOS versions cannot be reinstalled.

I don't want to end up with a Boat anchor so didn't try that.

If the BIOS can be rolled back it will show that in the Firmware Management secvtion. That shouldn't turn your notebook into a "boat anchor" If it doesn't work  it will simply leave the present version installed. 

UEFI BIOS and the Hardware Diagnostics make upgrading and rolling back BIOS safe. It is not like it was six or seven years ago.

Afraid you are wrong. There is a legacy bios and UEFI on this thing

I may resort to doing what I shouild not have to do.

Shutdown unplug main drive and start up. Should throw an error and let me into LEGACY Bios

Unplugging hard drive it just hangs, reason below

Solution is

I had installed a better video card Nvidia GTX-950. When hitting ESC it hangs and nothing happens. Black screen although you can see it change colors slightly

Fortunately both the onboard video card and the new Nvidia both using HDMI cable. So I just plugged back into my on-board video card. Booted up while tapping ESC and the Legacy Bios screen selection came up where I can select F10 to enter Legacy Bios

When you do a HP Bios update it appears to set everything back to default, in other words on board, selecting the on board video. Although you see it selecting HDMI port on boot so you think it is ok.

I've been working  with Dell  PC last 15 years at work, it don't matter what card I put in them. On boot I hit F2 and Bios loads so this bit me. Now I know

Hope this helps someone else.

If you can select the sections with a mouse cursor,  the BIOS is UEFI.

What is the difference between BIOS and UEFI?

Both BIOS and UEFI are firmware code stored on chips on the motherboard.

The Basic Input/Output System (BIOS) is responsible for setting up devices used by your system so that those devices can send and receive data. The BIOS has a limited amount of memory as well as other design constraints that limit what you can do with your computer before the operating system loads.

Unified Extensible Firmware Interface (UEFI) works with the BIOS and as an extension to the BIOS, to allow more functionality than what the BIOS alone is able to provide. UEFI provides more graphical menus, more detailed diagnostics, and allows the BIOS to contain more rich features, such as Secure Boot. UEFI can also open EFI compatible software from other storage locations, such as a hard drive or a USB storage device, for even more functionality.

I know the difference and I also know I have both
