Unable to update Windows 10 (UEFI Error) - Help please!

[AVLNCH]

Hi everyone,

 

I've been struggling for the last few months trying to get Windows 10 to update and I think I'm finally about to give up. I have attached an image of the error I get.

 

My knowledge in this particular area isn't strong but I'm willing to learn. Any help would be appreciated.

It's fixable but requires a full format and reinstall...

 

The issue is Windows 10 requires a GPT drive and yours is probably still MBR.

 

Can you list your full PC Specs please. Also right click your Start Button, select Disk Management, take a screenshot and post it please.

Thanks, are you good to do a full reinstall? 

 

You'regoing to need access to this thread during the process (a phone, tablet or laptop) as the process is fairly involved though it will seem harder than it is and once it's done it's done.

I can use my laptop to be on here whilst I do the full install. I'm good for a full re-install. I don't have a Windows 10 disk or bootable USB, and for some reason my PC is unable to make one with the Microsoft tool because it keeps giving me errors so I'm a little stuck on where to get something to install Windows 10. I can buy another key as I got this one as a the free 7 upgrade years ago, but I'd prefer to avoid it if possible.

That's a problem, what error does the tool give you? Can you not make the installer on your Laptop?

 

Tbh is sounds like you need a reinstall anyway.

It just gives me this. I've googled it and flushed my DNS as well as rebooting. No success.

Run the tool on your laptop.

[Master Disaster]

Or get an image from https://www.microsoft.com/en-gb/software-download/windows10ISO

Both want me to download the Tool. I get the same error on my laptop. I'm very confused...

 

EDIT: It's working now. I restarted my internet.

Redownload the tool from here or get the ISO from here and burn it to USB using RUFUS

 

Anyway heres the steps

 

So before you begin you'll need

 

A working Windows 10 installer (USB or DVD)

Your Windows 10 key

Also please unplug all your other hard drives except your Windows drive (THIS IS VERY IMPORTANT)

Obviously back up anything that's important to you before you begin

 

Phase 1

1) Reboot your system then head into UEFI, set the following options as I list them (if they're already that way then leave them be)

 

(I STRONGLY recommend you create a profile backup of your current UEFI settings before you mess with anything so you can revert if required)

 

Compatibility Support Module or CSM - Disabled

UEFI Fast Boot - Enabled

UEFI Secure Boot - Enabled (This option is not really required, if you cant find it don't worry to much)

Full Screen Logo - Enabled (Again optional but gives you a cool new boot animation)

 

2) Now save and exit (usually hit F10) then make sure Windows at least tries to boot. If Windows boots normally or boots and then blue screens your good to continue, if you get stuck on a UEFI error message then don't continue and instead note the error down then go back into UEFI, reload the saved profile and come and post the message.

 

Phase 2

1) Insert the Windows Installer into your PC, reboot and boot from the installer (making sure you choose the UEFI boot option from the boot menu if there are multiple choices)

2) Follow the wizard through until the hard drive partitioning screen then stop

3) Hit Shift+F10 to open a command prompt

4) Enter these commands one at a time pressing enter after each one (IF YOU DIDN'T UNPLUG YOUR HARD DRIVES THEN THIS INFO WILL NOT BE CORRECT AND WILL PROBABLY FORMAT THE WRONG DRIVE!!!!!!!!!!)

 

diskpart

select disk 0

clean

convert gpt

exit

 

If you didn't unplug your extra drives then do this (note i'm not responsible if you format the wrong drive

 

diskpart

list disk (and note down the ID number of your windows drive)

select disk x (replace x with the ID number you noted down)

clean (Doing this will erase EVERYTHING, make sure you got the right drive)

convert gpt

exit

 

5) Then close the command Window (click the X at the top) and carry on with the Windows install wizard until Windows is installed and you're at desktop.

 

Phase 3

1) Shut down your PC and reconnect all your other drives again

2) Download/install drivers for all your hardware

3) Install your Apps again

 

Enjoy your new Windows install. Now thats done your PC will be running in UEFI boot mode and any future reinstalls/upgrades should just work with no extra steps.

I'm using the tool to download Windows 10 but I think it's also making the bootable USB too. How can I get just the ISO to use RUFUS? Both the links take me to download the tool. I wonder if the tool is just downloading an ISO to the USB, But I can't tell.

Once the tool is finished downloading it will ask you if you wish to create a USB installer or save the ISO iirc.

 

Yeah it seems like the ISO link only works if your not running Windows, on a Windows system it seems to redirect to the tool automatically.

Okie dokie. I'll do all of the above and report back. Thanks in advance.

I completed all your steps and it worked a CHARM. Thank you very much for your help. You have no idea how much hassle you have saved me!
