If you want to learn the Linux system well, you have to start from the installation system. Let's share with you about the USB disk startup and installation of the Linux system.

Scan the newly added disk; the number after host/host can be changed into 0max 1max 2.

Write the boot.iso to the USB disk

Enter the USB flash drive startup interface

Adjust the boot order of the boot hard drive again after installation.

The system is installed.

If you encounter the situation that you can't get in when you start using the hard disk in the virtual machine to simulate the USB disk when writing to boot.iso startup.

You need to make the next conversion of the format of the hard drive and then re-burn the boot.iso in the USB drive

Check the first 512 boot bytes in the USB flash drive:

Hexdump-C / dev/sdb-n 512

Iso

Isohybrid boot.iso conversion format
