Windows 10: Latest Build Windows 10 fail, wont allow BIOS access

Hi
Just tried to install the latest W10 as a boot with W7 on SSD , installation failed and now will not complete installation. Will not reboot and reinstall, and prevents access to the BIOS to change boot to CD?
Any thoughts, suggestions or experience?
Looking at disassembly to remove SSD data cable ( Lian Li Briefcase build complicates everything)
Thanks
Dave

It is conceivable that the bios needs an update so the device will work correctly with the latest version/build of Windows 10. If you have just bought it then the version/build of Windows 10 is has will be what was installed by HP in their factory. No guarantee
it is now the latest.

The bios is supplied by HP and you check their website for a bios update for your model. You need to read and follow the instructions from HP.

 

Typically you can press a key combination to select boot source.. F12 on many systems.

Windows cannot disable access to your BIOS.

Welcome to TenForums. What type of media are you using to build your boot media DVD or USB?

 

Using DVD and the W10 DOES prevent keyboard access to BIOS. <DEL> is the usual key, tried it plus <F12> , <F10> ....no way.

 

I don't see how that it is possible for the Windows 10 DVD to prevent you from accessing the BIOS - access to the BIOS occurs before any DVD is read.
Is your DVD drive USB? Maybe it is interfering.
Suggest you take the DVD out, boot to BIOS, set the DVD as the boot device and save the setting, , then stick the DVD in and then reset.

 

Done that
released DVD, cold booted from a PSU switched off,
Dont forget that W8 & 10 do not actually cold boot unless a reboot is selected, the fast boot means that the state is just a deeper sleep mode?
I expect I shall have to disconnect drives to force a BIOS boot.

 

Flux: the latest Windows 10 doesn't provide enough information.
10.074 ISO is available: Download Windows 10 Insider Preview ISO - Microsoft Windows


Knowing what OS you're using as the 'host' and how (as the primary, as a dual boot on a separate partition / in a VM) you're trying to install Win10 is critical to helping solve the issue.

Also knowing if the firmware on your machine is BIOS or UEFI (I'll guess BIOS) is helpful.

The disk schema is informative
see: Disk Management - How to Post a Screenshot of - Windows 10 Forums

and lastly ...
Please follow this tutorial to provide the current operating environment of your machine.

Thanks

I'm not sure what OS you're referencing; specs say 7, you mention 8

As a test, try disabling Hibernation
Launch a Command Prompt with elevated privileges (Run as Administrator...)
powercfg /h off

restart your machine and post the current status.

 

I clearly say W7, the reference to W8/W10 is referenced only to the modified fast boot system.
Installing W10 latest stable release from a DVD , onto an SSD , directly, and choosing to retain data not a new install. This has previously always enabled a boot choice at startup hence dual boot reference.
Cannot disable anything as the computer is in a loop of not installing and not allowing an alternate boot.

 

Maybe hardware prob .. keyboard perhaps

 

How could a keyboard interfere with BIOS access?

 

I had a Notebook in and found that the BIOS supports only USB 2.0, the USB 3.0 ports needs drivers loaded when the Operating System loads.

 

I must admit I've seen something like this on a VM running in EFI mode.

What (if anything) does happen when you switch the PC on? Does the same thing happen with DVD inserted and DVD removed?

 

Berton, good point, I am using front USB3 port for wireless dongle, you may have saved me a tear down to access the SATA data cable!
Noooo..still prevents <DEL> access to UEFI/BIO even when in USB 2.0 native port. Looks like a teardown and SATA disconnect now.

DavidY whatever state or what is in DVD it justs fast boots into W10 installation sequence, then tells me it is unable to install and reboots.........ad infinitum.

Looks like a drive reformat and install from scratch! Good to have that option with the 10074 iso.
