HP PCs - Secure Boot (Windows 10) This document is for HP and Compaq PCs with Windows 10 and Secure Boot. Enable Secure Boot to block malware attacks, virus infections, and the use of non-trusted hardware or bootable CDs or DVDs that can harm the computer. First of all lets get one thing out of the way. UEFI is NOT BIOS. That sounds like semantic squabbling but here it really matters. What you were doing before is setting the boot priority to harddisk and then from the OS to set the boot partition(s) disabled in the partition table so the bios skips past the harddisk onto usb and network options. First of all lets get one thing out of the way. UEFI is NOT BIOS. That sounds like semantic squabbling but here it really matters. What you were doing before is setting the boot priority to harddisk and then from the OS to set the boot partition(s) disabled in the partition table so the bios skips past the harddisk onto usb and network options.
In general, install Windows using the newer UEFI mode, as it includes more security features than the legacy BIOS mode. If you're booting from a network that only supports BIOS, you'll need to boot to legacy BIOS mode.
After Windows is installed, the device boots automatically using the same mode it was installed with.
To boot to UEFI or BIOS:
- Open the firmware menus. You can use any of these methods:
- Boot the PC, and press the manufacturer’s key to open the menus. Common keys used: Esc, Delete, F1, F2, F10, F11, or F12. On tablets, common buttons are Volume up or Volume down (find more common keys and buttons). During startup, there’s often a screen that mentions the key. If there’s not one, or if the screen goes by too fast to see it, check your manufacturer’s site.
- Or, if Windows is already installed, from either the Sign on screen or the Start menu, select Power () > hold Shift while selecting Restart. Select Troubleshoot > Advanced options > UEFI Firmware settings.
- From the firmware menus, boot to drive or network while in UEFI or BIOS mode:On the boot device menu, select the command that identifies both the firmware mode and the device. For example, select UEFI: USB Drive or BIOS: Network/LAN.You might see separate commands for the same device. For example, you might see UEFI USB Drive and BIOS USB Drive. Each command uses the same device and media, but boots the PC in a different firmware mode.Some devices only support one mode (either UEFI or BIOS). Other devices will only allow you to boot to BIOS mode by manually disabling the UEFI security features. To disable the security features, go to Security > Secure Boot and disable the feature.NoteSome older PCs (Windows 7-era or earlier) support UEFI, but require you to browse to the boot file. From the firmware menus, look for the option: 'Boot from file', then browse to EFIBOOTBOOTX64.EFI on Windows PE or Windows Setup media.
UEFI and BIOS modes in WinPE
Detect if WinPE is booted into BIOS or UEFI Mode
Query the registry to determine which mode the device is in. You can do this from the command line:
Return code | Firmware mode |
---|---|
0x1 | BIOS |
0x2 | UEFI |
Use it in a script:
Note that between
delims=
and ' %%A
is a tab, followed by a space.Make sure you boot into the right mode every time
Here are a couple of ways you can make sure you're booted into the right firmware mode every time you start your PC.
Use preformatted hard drives, and use a method that doesn't automatically format the drive.
Disable Legacy Usb Windows 10 Boot
If you want to ensure that your drive boots into a certain mode, use drives that you've preformatted with the GPT file format for UEFI mode, or the MBR file format for BIOS mode. When the installation starts, if the PC is booted to the wrong mode, Windows installation will fail. To fix this, restart the PC in the correct firmware mode.
Remove the UEFI or BIOS boot files
If you want a PC to only boot into a certain mode, you can remove the files that Windows PE or Windows Setup use to boot in UEFI or BIOS mode. Remove the following files, depending on the mode you want to boot to.
Boot only when in UEFI mode
Disable Legacy Usb Windows 10 Install
Remove the bootmgr file from the root of the Windows PE or Windows Setup media. This prevents the device from starting in BIOS mode.
Boot only when in BIOS mode
Remove the efi folder from the root of the Windows PE or Windows Setup media. This prevents the device from starting in UEFI mode.
