I purchased my PC, already installed with 8.1. I have since done the upgrade to 10, but I still have 2 partitions on my hard drive, one for "Recovery Image" and the other for "8.1 Restore".

I assume these are no longer applicable and needed, but wanted confirmation of this. If no longer needed, can I just delete the data and combine partitions to gain the extra drive space (I have EaseUS Partition Manager)?

Not sure if I should reuse these partitions to set up a Windows 10 recovery, or use a USB bootable device instead for this. If the latter, can someone provide a link for this? Thanx,
