P3 - 171 how to change Windows 8.1 to Windows 8?

I bought my P3-171. I have downloaded all Windows updates, then I installed Windows 8.1. Then everything became extremely slow, so I decided to go back to Windows 8. Before that, I installed the latest version of the BIOS to v2.07. I see Windows 8.1 has created a new partition of 300 MB.

Now my questions are:

1. How can I delete this partition?

2. How can I use the full factory reset between the recovery DVD (option 2 on the list)? When I try to use it, it is said, that all information must be deleted before you continue (but how?)

3. If I could somehow, active the 2nd point mentioned above, I will lose the system partition created before buying P3? If Yes, my Windows 8 will remain active after reinstalling it? I don't know if there is any information on this system partition.

I have reinstall Windows 8 but this partition created by Win 8.1 always there. I know it's my fault, but I don't want to have this... That's why I decided to do a complete factory reset (I don't know how it is in English, exactly, but it's the 2nd option after the start-up of the plant since the recovery DVDs).

Sorry for my English, I hope, you can understand my problem, and I hope also, could someone give me a help as well. Thank you, guys!

Just use the recovery for Windows 8 options to restore the system to Windows 8.

Don't you worry about anything else created for Windows 8.1.
