China DOS Union

Installation environment:
Windows XP Professional SP2
DDR 512M
------------------------------------------
Allocate 16M memory to DOS under VMware (is that enough?), the installation file is the MS-DOS 7.10 CD installation ISO version from the top post in the forum. When starting the installation, there was no problem. After the blue screen content was completed, it restarted. At this time, a problem occurred. The installation could not continue. It prompted: Invalid system disk. Insert the system disk and press any key to continue.

What's the matter with this? Have any friends encountered the same problem as me?
Help me~.
Большое спасибо~！

In the section "Some Installation Precautions" of the article "MS-DOS 7.10 Installation Instructions", it has long been clearly mentioned:

When installing using installation floppy disks/cd - ROMs, including when installing in a case where the hard disk is not partitioned (for example, in a newly - created virtual machine), please pay attention to setting the BIOS to boot from the floppy disk/cd - ROM accordingly (if it is not set) until the installation is completed.

Therefore, please pay attention to reading the installation method carefully first.

I'm sorry, I didn't read carefully enough -_-//

I encountered the same problem as you. Finally, I added a virtual floppy drive to the virtual machine, and there was no problem with installing it using a floppy disk image (*.img, which can be downloaded online). 16M of memory is sufficient. Good luck to you ^_^

Encountered a problem
It seems that just searching will be okay
Thank you, I was also confused
Now it's good
