After Linux is installed, "the allocated partitions cannot be allocated ."

MBR (Master Boot recorder) Stores hard disk information in the Main Boot Sector. MBR is the heaviest hard disk.
This is because two important items are recorded in the MBR: The Boot Management Program and the partition table ). Therefore, we are modifying the partition table.

Due to the limited capacity of this MBR block, at the beginning of the design, only four partition records were designed.
Partition records are called primary (primary partition) and extended (extended partition). That is to say, a hard disk can have up to four primary + extended sectors, extended can only have one
Here, if you want to partition into four disk partitions, You can at most:

P + P

P + E

To partition. (Because extended cannot be used directly, you still need to partition it into logical)

Because there is a primary partition and an extended partition, only two primary partitions can be created at most.
The/AND/boot are regarded as the primary partition in sequence, so swap cannot be created ......

Solution:
Use the partition tool to divide all the remaining space into extended partitions, and then install the system. Divides the entire hard disk into one primary partition.
And an extended partition. Linux is installed in the remaining space of the extended partition.
