Windows 10: Partitioning trouble after upgrade, clean install and revert back

    Partitioning trouble after upgrade, clean install and revert back


    Hello
    Recently upgraded to w10 from w8.1 via the upgrade option, then proceeded to make a USB boot with w10 and performed a clean install.

    However, something is fishy with my system and w10 so for now i want to revert back to w8.1 via a clean install of w8.1
    When i installed w10 however i noticed i have an abundance of partitions, and preferably i would only like to have my SSD and HDD as optional storages spaces. I do of course not want to delete any necessary recovery or system partitions, but to me it seems like i currently have too many.

    Which of the partitions in the picture below can i delete?
    is it safe to delete all the recovery partitions when clean installing w8.1 from usb? meaning that will the installation create the necessesary partitions required by windows?

    hope someone can help me out.
    see picture for info(gjenoppretting = recovery)

    you can delete All the partitions on Disk 1, C drive disk

    the first 300MB partition is recovery for windows 8 and the last 457MB partition is recovery for windows 10

    can i even delete the EFI partition? or should i even?
    if i understand you correctly, ill then ,atleast before the install, only have 1 big C: partition in disk 1, and the D: partition in disk 0? and then w8.1 installation wil create a recovery partition during install?

    thank you for the quick answer!
