Hi, that looks like a legacy BIOS installation with Windows partitions on Disk 0. However, the Recovery partition is missing. Further, there's no unallocated space; sometimes Win 10 creates a second recovery partition when upgrading.
If your recovery partition is missing, if you try SHIFT left click restart, you will not have any advanced troubleshooting options (Safe Mode options, System Restore, Command Prompt).. - you can try that.
However, people have reported only having two partitions as you have with MBR/legacy BIOS.
from the link below:
Partition layout If you install Windows using a bootable USB key made by Windows Imaging and Configuration Designer (ICD), it creates the following layout by default: a system partition, a Windows partition, and a recovery tools partition.

I would suggest shrinking C: by, say, 600Mb at least, and trying again manually, following the recommendations here:
Upgrade to Windows 10 Windows 10 Installation Upgrade Tutorials
- uninstall AV, clean boot, disconnect any unnecessary peripherals....
After that, time to consult the logs.
@Pluto46 - you've too many Recovery partitions. You may need to delete the ones that aren't used. (Whether that's what causing the upgrade to fail I can't be certain though, of course).
Also I recommend creating some 500Mb unallocated space on your system drive (which the above should achieve).
I'd also want to see your disk layout as viewed e.g. by Minitool Partition Wizard, please, as that shows a partition Disk Management won't.
(To work out which Recovery partition is used you need these commands from an admin command prompt:
BCDEDIT
REAGENTC /info
)

Those recovery partitions appeared today I think. I was surprised by how many there were. I don't look at it very often though. I'll get hold of that partition wizard in a bit.
How do I know which recovery partition is in use?

- you play 'match the numbers' between the reports and so identify the partition.
After reading all your suggestions about tutorials and MS docs, I think the only way to repair the disk and show 3 partitions as needed, is to start over with a reinstall and a clean / blank /wiped disk. I then should be able to also switch to UEFI.
My motherboard did not give me the same abbreviation, but called it either EFI or UEF, I forgot witch.
I am assuming that is the same as UEFI?
What do you think? or is there another way to do it?
Thanks
