Locked Is there any BIOS that only supports UEFI (GTP) boot?

[casperyc]

Tablet is a Teclast Model X80H.


Sorry if the title does not make any/much sense, but I have never had such problems.

I can boot the tablet using a PE from USB, I then installed win10 x64 (fresh with new partition with MBR)

But after that, BIOS can only detect one UEFI-built in boot as shown.


It couldn't boot from my newly installed win10. Can't even have the option to boot from local disk???
It was orginally one win8.1 with GTP partitions...
And I could see a boot option "Windows Manager" (it is from win8.1? )

Question, does it matter how I partition the disk using GPT or MBR?
Windows fresh install should write the "boot info" to the disk, so it will boot up??

Any suggestion for what I should do now???

YES if u r in MBR the the the boot info is in the first 4k of the partition and if u r in GPT then the boot is in a partition called EFI comonly in the bios showen as "boot from windows boot manager"
for u r case if u want to go passe from GPT "and it is u r case" u must format all the disk so u can install windows as MBR and doing that will erase the efi partition as well
as i have anderstand u r are in GPT as most all new pc came. me too had to go from GPT to MBR for wil but this time i have returned to GPT mode cause it is very pratique
in MBR u can create only 4 partiton in hard drive but in GPT u can do what u want. i suggest that u create a bootable usb with refus in UEFI mode and reinstall windows and stay in GPT mode .

Hi,

If you are sure that the disk is in MBR and not GPT it will not work because for UEFI boot you need to have the disk in GPT.

Boot from the Windows 10 install and after selection the language press SHIFT + F10 to access the Command Prompt, type MBR2GPT /convert to try to convert the disk from MBR to GPT if it works the machine should boot fine after the change.

So in that case, my BIOS does not support MBR ?
Never seen that kind of BIOS before.

At the moment, is only as the ``built-in UEFI'' , which does not do shit..........

Not exactly, The BIOS only have UEFI mode and that implies GPT.

Which Motherboard Do You Have ! ?

Which Motherboard Do You Have ! ?

He's definitely got a wired one.....


But mine still does not boot up for some reason.
Just tried re-partitioning it into GPT and reinstalled win10 again...

Not success.

BIOS now shows the Windows Boot Manager, but cannot boot, and goes into the "next" option, which is the "built-in UEFI" that does some more nonsense....

 

[MrZeb]

Did the installation complete or it failed on the first boot that the installation does?

It would really help a lot if you posted more info about this tablet, such as make/model/etc, etc... so that others can better help you.
Also, please only use lookimg.com next time when posting images. I've now edited your post.

Failed on the first boot (never booted up)

Thanks.

I will see if I can edit it.

It's FB4M

Even that website doesn't offer support for its products... pretty much tells you everything you need to know about this product. After googling teclast tablet format install win10 there are some posts and videos, not for the model you specified... Best of luck, not sure why the os that came with it wasn't good enough for you?

From what I can find, it's a dual-OS (Android 4.4.4 and Windows 8.1) 8" tablet with 2 gigs RAM and 32gigs emmc HDD.

Is this correct?
If so, there is very little information available on how to properly install Windows 10 on this device. From what I found, it's difficult to do, but possible.
If you are eventually successful, you will still need the proper touch and orientation sensor drivers for it. For that, google is your friend.

Good luck!

@casperyc Check if there is any option on the BIOS related with Secure Boot and disable it.

Another possibility is to let the system boot from the flash drive and instead of starting the installation of Windows 10 choose Repair then you will see an option like Continue (Exit and continue to Windows 10) try that to see if it boots using Windows 10 that is on the HDD/eMMC.

Secure boot is disable.
Quiet boot is disable.
Fast boot is disable.


At the moment, I can only boot using PE.
And I can see that Windows Boot Manager.
The ESR partition and system partition is all good to go...

But I just cannot boot windows....

Every time it goes into the

Press ESC in 2 Seconds to skip startup.nsh,any other key to continue

That is correct. That's the one.

I just don't want to use win8.1 and wanted to use win10 instead...

You may want to re-check your install partitions again and make sure they are not deleted by booting into PE or whatever you are using to install Windows 10 and check your partitions. I suspect an issue there.

If you meant the EFS and "another" (whatever) partition for GPT, I can see them all. I have also checked that the BCD file is showing the correct information.

BIOS does have the Windows Boot Manager, but it just does not seem to be reading from there....

I am using

WinNTSetup v4.0

to install win10 (esd file) from this site.

 

[MrZeb]

Why don't you use a flash drive containing a clean Windows 10 install disk?

If you use Rufus to transfer the Windows 10 ISO to the flash drive it can be made compatible with UEFI and BIOS mode if you use the hot key ALT+E (one time only this setting is preserved between sessions).
