What kind of partition should Linux be installed on?

Linux 菜菜”: Linux needs a new partition installation, I don't understand, the partition here refers to the extended partition created by Fdisk under DOS, or the logical drive or the remaining space on the extended partition, and Or a non-DOS partition. For example: my machine is divided into two areas, one partition is C drive, the second partition is D, E drive, I want to install Linux now, should I delete the E drive, or create an extended partition installation What? Expert: Please forget the concept of A, B, C, D drives. Linux does not have this concept like other UNIX. The so-called partitioning is to divide the hard disk into several logically independent parts, each of which can be used independently without affecting each other. You can create a file system on a partition or create a swap area for virtual memory. The partition is recorded in the first sector of each hard disk, called "Master Bootstrap Record" (MBR). If your Linux is for personal use only, then it is best to set up three partitions for it: 1, root file system; 2, swap; 3, /usr file system. Because DOS Fdisk is stupid, do not know how to set up other system partitions, so you just let it set up the place you left for DOS, and install DOS in advance, and then use the Linux fdisk program to set up the Linux partition. Linux can be installed on four possible primary partitions, or on a partition within an extended partition, and there can be multiple extended partitions on a single hard disk
