I have an hp pavilion 17 power laptop with windows 10 home pre-installed. Today when I was creating an extra partition for Ubuntu and when I looked at the disk management window I was surprised because it had 4 recovery partitions instead of only one which is showed in the file explorer.

Are all of these extra recovery partitions with no drive letter important?
Can I safely delete these extra partitions?
