Windows users who are familiar with Disk Management may notice some partitions with no name attached to them.
Usually, those partitions or volumes will be marked as "Disk 0 partition 2" or so.
Some users may have intentionally or accidentally deleted partitions because of insufficient drive space; they might think there won't be any problem if deleted since they have no name.
But that's not true – because these partitions you deleted are likely to be boot partitions.
There are generally 2 types of boot partition: an EFI partition for the GPT drive and a System Reserved Partition for the MBR drive.
If you have accidentally deleted these two volumes, your computer will be unbootable.

Both these 2 kinds of boot partitions are responsible for booting the operating system, so they are never recommended to be deleted.
