Record the process of installing win7 on a virtual machine

Question 1: how to solve the problem that the virtual machine installation system repeatedly enters the DOS toolbox

The main reason for the solution according to the following method is that the virtual optical drive is loaded incorrectly. When the virtual machine is created, the default mode is SATA mode, while the GHOST system supports IDE mode.

Question 2: the computer failed to start and is trying to load 64-bit applications, but this cpu is different from 64-bit mode (my thinkpad's way to enter bios is to press F1)

Check that the intel virtualization technology option is turned on correctly in the bios settings!

If the corresponding feature is enabled, you need to check whether 360 security and health is installed, and turn off its core protection engine. This × × function will prevent virtual machine software from being virtualized, resulting in the 64-bit virtual machine system cannot be installed normally.
