① Partitioning

This time, we will divide it into 3 basic plans + 2 logical partitions. Use the fdisk command to partition the partition until the following status is obtained, as in last time.

Command (m for help): p

Disk /dev/sda: 42.9 GB, 42949672960 bytes, 83886080 sectors

After creating and saving the partition, the following error message appears, so I checked it. → I got a lot of information that it will be reflected by restarting.

WARNING: Re-reading the partition table failed with error 16: Device or resource busy.
The kernel still uses the old table. The new table will be used at
the next reboot or after you run partprobe(8) or kpartx(8)
Syncing disks.

After shutting down and vagrant up again, it broke ^^; I don't know the cause, so I put it on hold!
