Can't install w10 update, UEFI error?

[discoslice]

So, I have Windows 10 already installed on my PC. I upgraded it last Summer from Windows 7 for free.

I've been trying to update it for the past 6 weeks but keep getting the error: "Windows 10 couldn't be installed. Windows can't be installed because this PC has an unsupported desk layout for UEFI firmware."

I have 3 hard drives and Win10 is running on my main SSD, disk 0. I remember having some funky upgrade issues and needed to unplug certain hard-drives but forgot why. Heres is a look from Disk Management. I've got an MSI m-board plus BIOS, all new.

You have 5 partitions (4 active) on your boot drive. It is also probably a using MDR partitions, which has a limit of 4 primary partitions. Win10 UEFI machines would normally use GPT instead of MBR. There also doesn't seem to be a Win10 Microsoft Reserved Partition (MSR). So pretty non standard.

It is probably fixable. But if it was me, I would backup my data and do a clean Win10 install. This approach is sure to work and can be done in a known about of time. Other options are more risky in terms of not permanently fixing the problem or accidentally stuffing up the partitioning and loosing your data.

Thanks for your reply. Ugh I'd hate to do a clean install again. I checked that link you provided - so the possible "fix" is to add MS Reserved Partition to my main drive?

Anyone else on this?
