Virtualbox error: "Fatal: No bootable medium found !"

Virtualbox error: "Fatal: No
Bootable medium found !"

Using virtualbox to install the system has a very high chance of this error, because when brother encounters the same problem, he crashes "Fatal: No bootable medium found! "A lot of content appears

Most of the above problems are caused by using ghost to install the system in virtualbox.

You can enter a PE system in a virtual machine. This is written into the memory, so you can enter it. Go to the disk management tool, select your hard disk, and select "Update MBR". OK, restart. (P.s. It is best to do this first, and then re-use ghost to install the system)
