Windows 10: keystroke(s) to enter BIOS/Boot Manager

Hallo
first post here; I have a Linx 8 tablet running Windows 10, and despite several hours of web/forum trawling I cannot access my BIOS settings to view my boot manager, either through the Settings/Restart method, or in Safe Mode. I can get to a screen that lets me choose between either UEFI Settings or Boot Manager (by holding the power and the volume up buttons together at start up). Selecting the UEFI option takes me to the expected prompt, but choosing Boot Manager just starts Windows as normal. I simply cannot access my Boot Manager; I have disabled Fast Boot.

AFAIK, I have tried all possible options from within Windows 10, is there a keystroke that will allow me to do this?

Thanks
Brendan

Windows 10 BSOD on shutdown or after long usage

I managed to enter bios but thats not really an achievement, could i safe boot from bios somehow?

I managed to get into actual windows and got the minidump file and system information file (both after driver verifier).

Windows 10 Update Always Fails!

Paul,

To elaborate on @lacrumb's post - different PCs use different keystrokes, but almost all of them have a special key to enter the BIOS at startup. In my case it is the <DEL> key. When you first turn on your PC it will tell you what key to hit to enter the
BIOS. The message will flash by quickly, and you need to be quick on the keyboard, but once you get into the BIOS you should be able to find a list of boot devices, and change the order in which the PC tries to boot from each one. Don't change anything else
in the BIOS!

 

See if this will help you UEFI Firmware Settings - Boot to from inside Windows 10 - Windows 10 Forums and welcome to Tenforums

 

Thank you. Am I being n00bish perhaps? I can't access boot manager in the 'conventional' way because my bios is UEFI?

Your link looks like it will help answer these questions.

 

I don't think you are being Noobish. I am completely unfamiliar with your tablet model and have no idea how to boot into bios other than the link I posted. I would want to also. Perhaps if you downloaded the Manual for your tablet it would show you how. I wouldn't think the reason for your problem is UEFI mode.

 

I'm afraid I don't have the motherboard specs for this tablet; it just appears that the Boot Manager link is either broken or disabled. I can access the EFI settings but it presents me with something resembling a Command Prompt, and I'm not too sure about making any changes there. I found this link also, for anyone else watching.

What You Need to Know About Using UEFI Instead of the BIOS

Using the powerButton+volumeUp method (or other methods within Windows 10), I am presented with the following



:

Choosing Boot Manager I get:




If I select Windows Boot Manager, Windows 10 just starts as normal, no boot options, if I select Internal EFI Shell I get:





Which I am unfamiliar with.

Anyway thanks again, research continues.

The windows boot manager will take you straight into Windows if the is only one boot menu entry.
The final picture is the EFI shell.

Are you trying to get to this Advanced Startup Options - Boot to in Windows 10 - Windows 10 Forums ?

Apart from that you might be seeing all you can change. I'm running Windows 10 on MacBook which boots through UEFI and there are precisely zero pre-boot options for me to change. I can either boot Windows or not - I can't change boot order or set any flags to turn secure boot or processor features off or on or anything at all.

 

@lx0
I am beginning to suspect that this might be the case for me too. I cant understand why a Boot Manager link is provided in Advanced Start Up if these options are unavailable. I connected a USB drive with Fedora 23, and chose Boot from USB in Advanced settings and the dialog says, cannot boot from USB no USB boot option exists, use your boot manager to change settings. I press Windows Boot Manager and Boom, back to desktop

Sigh.

 

If you only have 1 OS installed and are in UEFI mode, you only have 1 boot manager. If you select Boot Manager it will take you to your OS. If you have a UEFI created USB, you should have 2 boot managers and should see a choice. If you have an MBR created USB, it does not have a Windows Boot manager. You would have to disable secure boot and fast startup and probably the CSM settings, if you have that.

 

Hi,

That looks like a programming environment to me.

Ok, that is very clear now. I believe the version of the Fedora installer I have is EFI (not UEFI); when I connect it to my PC it shows up as an EFI drive. On my tablet, I have disabled Fast Start Up and Secure Boot. I believe it may be possible to revert to Legacy Mode (according to the link I gave in #5).

FWIW I am already running Fedora 23 on my main PC (dual boot with Win7). I'm just experimenting with the possibility of running Fedora on my tablet too. Not a crucial problem, and I'm also aware of the likelihood of bricking my tablet, so I will proceed with much caution.

Many thanks everyone, and thanks for the warm and uncritical welcome.

I believe that is the way it works. At least on my computer, if I have 1 item with a Windows boot Manager, I have only 1 Windows Boot Manager option to choose. If I have more than 1, I have a choice of Windows Boot Managers. I'm not real sure of the distinction between EFI and UEFI if there is one. I have an EFI Boot Partition.

 

this looks promising, adding a second boot option via elevated command prompt:

Booting from a stick, or maybe even an SD Card might be a safer option!*Wink
