Feature update to Win10 2004 “found some issues”

Topic

New Reply

In preparation prior to installing the above update Windows says “We found some issues. Select this message to fix and finish updating.”   Then this: “Windows can’t be installed because this PC has an unsupported disk layout for UEFI firmware. Win 10 Pro 1909”

I have two HDDs C, which is the disk in use, and D, a storage disk containing photos, etc which I refer to rarely. 
Can you please help?

Can you post a screenshot of the full Disk Managment screen for that machine (Win R, diskmgmt.msc).
Use Windows Snipping Tool to take the snapshot, save to PNG, upload.

HI Paul – is this ok?  Neil

Great, just what we need.

Your disks are not set up for UEFI because the Windows disk is not GPT – you have 3 partitions in a standard Windows setup, a 100MB EFI (required for BitLocker), recovery and the rest Windows (required). You can remove the recovery partition manually, but it’s generally not worth it.

You seem to have an MBR setup. You can check this.
Win R
msinfo32
Look under “BIOS mode” in the right pane.

To convert to GPT and UEFI you need to confirm that your PC has a UEFI boot mode.
Go into the BIOS and check if the Boot Mode has Legacy and UEFI. Do not change anything at this point.

If all is well, make a full backup to USB hard disk.

Follow the instructions on this page to convert the disk.

cheers, Paul

Hi Paul

I’m a bit worried that you might have overestimated my IT ability!  Thank you very much for your advice. I will set about following your instructions, and will let you know if I am successful.

I have not overestimated, you have underestimated. 🙂
Good instructions and a few questions are enough to make even seemingly difficult things achievable.
