I tried to easily put CentOS-7 in a PC that I no longer need
at first
Things necessary
PC, USB (about 8GB)
Obtaining installation media
https://buildlogs.centos.org/rolling/7/isos/x86_64/CentOS-7-x86_64-Everything-1511.iso
Create USB installation media from ISO file
Use Rufus
https://github.com/pbatard/rufus/releases/download/v3.12/rufus-3.12.exe
Specify the iso file from the boot type selection and
Specify the partition configuration, target system, and file system and press the start button.
If you see this after pressing the start button, select Write as ISO image
Since such a warning message appears, if the data in the USB memory to be used remains, move it to a PC etc. before doing it.
When the writing is completed, a notification sound will sound, so this completes the USB installation media creation.
PC USB boot
After inserting the USB installation media into the PC you no longer need, start the PC and then press F12 (depending on the PC model) to enter the Boot Menu.
Select USB to enter the CentOS 7 installation screen
Select Install CentOS 7
Select language as Japan
I’ll go into the installation overview so what to do

If you press [Finish], you will get angry if there is no area, so select [Secure area].
Select [Delete All] → [Reuse Space]
When you return to the installation summary, the yellow display disappears and the minimum settings are completed, so select [Start Installation].
