From what you said, it sounds like you tried to upgrade from Win8.1 to Win10, but that failed in the process and now, you can not boot the PC into a working OS.
Is that right?
You should NOT have messed with the partitioning prior to doing the Upgrade. The Win10 Upgrade tool knows how to repartition your drive for the upgrade and will do that itself, if it is needed, during the Upgrade.
Did you actually make it part way through the Win10 Upgrade? OR, did you just repartition your drive and are NOW trying the Upgrade?
While Microsoft tells you that there is no risk in the Win10 Upgrade, because they let you believe that you can always revert back to your original OS and setup within 30 days, the ugly fact of the matter is that the Win10 GoBack function has proven to be unreliable -- and when it fails, it can leave machines in a corrupted state -- which doesn't always happen, but it does happen often enough to be a problem and you won't get any warning in advance that it is going to trash your PC!
If that is not bad enough, the Win10 Upgrade is know, in some cases, to corrupt the Recovery partition stored there by the OEM that built the original machine. This pretty much guarantees that no HP Recovery is going to work.
So, if you actually made it part way through the Upgrade and NOW, want to restore Win8 to your PC, you need to let me know that.
