Can't get into Intel Motherboard's BIOS

hayley3 · Aug 31, 2017

So I was having multiple issues and tried to reinstall Windows but it wouldn't work, saying my disk was GPT, or MBR or something. I still could not re-install Windows so I cleaned the drive using DiskPart but still I could not reinstall Windows, so I read this:

The resolution to this issue depends on the the hard disk volume size:
• Follow these steps if the hard disk volume size is less than 2.19 TB:
1. Temporarily disable the EFI Boot Sources setting in the BIOS:
1. Restart the computer, and then press F10 to enter the BIOS.
2. Navigate to Storage > Boot Order, and then disable the EFI Boot Sources.
3. Select File > Save Changes > Exit.

So that's what I did and I was able to install Windows 10 from an ISO file however now I can't get back into Bios to set it back.

I have read you can change that by using Windows but I cannot cause there is not UEFI firmware settings menu.

The computer is running fine but I can't access the BIOS which is driving me crazy. My motherboard is an Intel DZ77GA-70K.

Thanks,
Cheryl

Edited to add: So I was thinking to reset the BIOS and there is a reset button on the motherboard...so maybe I should just do that? I also downloaded an BIOS update and BIOS recovery just in case. Maybe just run the recovery.

If you installed system in Legacy mode (UEFI disabled), then you can't change BIOS back to UEFI boot after that or your system will not boot into windows anymore.

Anyway - this is how you enter BIOS after installing windows 10.

I don't have the UEFI option in Windows.

So I don't understand why I was forced to changed that setting to install Windows in the first place.

UEFI is not an option in windows.

Windows installation error message about MBR/GPT depends on partitioning scheme on your HDD/SSD.
If your HDD is partitioned in MBR, you can install windows in legacy/CSM mode only.
If your HDD is partitioned in GPT, you can install windows in UEFI mode only.
You can change partitioning scheme on your hdd with appropriate commands:

diskpart
list disk
select disk x
clean
convert gpt
or
convert mbr
exit

(Clean command is data destructive. Use with caution.)

I want to start over...and format the disk and reinstall windows. Format used to be so simple. Anyway, here are my results:

Clean not allowed on a disk that contains pagefile volume.
Convert not allowed on disk containing current boot.

Thank you so much for helping!

If you want to start over and install windows again, then boot from windows installation media first.
Only then you can use clean command.

The drive is a brand new SSD drive. I am pretty sure I changed it in diskpart to an MBR not realizing the new SSD was a GPT.
I need to convert it back.
I am not sure what you mean. How can I use a DOS command in a windows application? I know it's not technically DOS.

hayley3 :

You boot from windows installation media into command prompt mode and type in those commands.

Edited:
I did get that to work using the Windows 7 disk and it still gives me the same error...Clean is not allowed on the disk containing the current boot.

What commands did you use?
Can you post photo of it?

hayley3 · Aug 31, 2017

I can show you it via gyazo. Hopefully it will work

You didn't boot from windows installation media.
There should be your windows installation USB flash drive listed also.

You can't clean the drive you booted from.

hayley3 · Aug 31, 2017

Oh I get what you are saying I think. Well I started the computer with the Windows 7 disk. It won't start from the USB.

If I could just get into the darn bios.

Edited to add: I can hook up another hard drive but off to work for now.

hayley3 :

Do you mean DVD disk? Didn't think anyone used those anymore.

hayley3 · Sep 1, 2017

Only cause it won't let me use the Windows ISO I put on the flash drive.

I'll be at work all day today. But I can hook up the other hard drive later, will that work?

Edited to add: what about using MBR2GPT.exe, would that work?

SkyNetRising · Sep 1, 2017

Yes, that also could work. But mbr2gpt is available for windows 10 only.
Are you installing windows 10 or windows 7 ?

Anyway - why do you need UEFI boot? It's not such a big deal.

hayley3 · Sep 1, 2017

I can't get into the BIOS, although I did get in this morning so I"m guessing I'm having a MB issue.

Also when I got in this morning, USB boot is checked, but it wasn't booting from the USB flash drive.

So I read that on Intel Motherboards you can hold the power button until it beeps 3 times and it will give you a Bios menu which it did...was awesome. so that still didn't work but I noticed an error code on my motherboard which said it hadn't detected my keyboard...believe it or not. The keyboard was working fine btw. So I hooked up my corsair to it and got right into the bios.

I did convert the SSD drive back to UEFI and re-installed Windows 10 also.

Anyway I just wanted to thank you for all the time you spent helping me...It was much appreciated!
