can not replace disc when install Win OS

[Aphrodite]

During windows installation, the disc (iso file) cannot be replaced, such as the virtio drive disc.

I don't understand your problem. You cannot usually remove a disk during the installation of a Windows OS on a physical machine either. What is requesting a disk change during an OS install?

During windows installation, the disc (iso file) cannot be replaced, such as the virtio drive disc.

Warning: The virtio-scsi controller will only be seen by OSes with device support for
it. In particular, there is no built-in support in Windows. So Windows will not see such
disks unless you install additional drivers.

... and you can't have installed third party drivers before you even installed the OS.

During windows installation, the disc (iso file) cannot be replaced, such as the virtio drive disc.

The easy solution is to add two CD drives to the VM, and insert both ISO files at the beginning. For details see Paravirtualized Block Drivers for Windows > Setup During Windows Installation. After finishing the installation, you can shut down the guest OS and remove the 2nd CD drive, if you want.

Two optical drives is a solution.

When installing windows to disk partition, I want to eject win.iso, insert virtio-win-0.1.171.iso to install the virtio-scsi disk controller driver, and the eject disc will cause the virtualbox to crash.

VMware workstation can eject CD and insert pvscsi driver CD.
QEMU for Windows can do it, too.
