Hello,
I solved this problem by simply: In the Devices menu --> Insert Optical Disk.

It can give the error: FATAL: No bootable medium found! System Halted.
when you inserted the installation CD after starting Linux in VirtualBox.

Hi,
did you create a virtual disk?
does this virtual disk contain anything?
did you define how the CD drive is emulated (disk image or real drive)?
did you put the installation CD of an OS in your drive?

Hello,  Actually, I followed the FAQ for installing VirtualBox, I don't know if there's anything else needed with that!!

Hello,

It's important to understand that VirtualBox creates a virtual machine. This machine doesn't have an operating system installed. So once your machine is created, you need to install an operating system (Windows, Linux, BSD... whatever you want)

For that, you start your machine for the first time, press F12 to choose what to boot from, and then you start from the appropriate medium (CD-ROM for example).

The main partition must be activated!!!!

For the DOS, I did it with fdisk; otherwise, you have tools for that.

Ha! I was trying to make a DOS virtual machine and I had the same problem!

You have to understand that the problem is not your adjustments or your manipulation: it’s that your virtual hard drive is not *EXACTLY* as DOS understands it, which generates the error message!

I solved it as follows:

1. Prepare a DOS virtual machine via VirtualBox with all the default settings except maybe the memory; by default for DOS, VirtualBox gives 32MB which is a bit low!!! I gave it 512MB :)

2. Insert a CD-ROM or a virtual floppy disk for your DOS. There's a nice selection here: http://www.allbootdisks.com/

3. Start your virtual machine and go to the command line

4. Run FDISK, create a primary DOS partition, restart the virtual machine. Boot AGAIN from your CD-ROM or virtual floppy disk.

5. Again at the command line, run FORMAT C: ... give a name to your hard drive

6. From drive A:, type SYS C: --> This copies the necessary system files.

7. HERE’S WHAT FIXED MY PROBLEM: Last step, run FDISK /MBR

8. Eject your CD-ROM or virtual floppy disk, restart and enjoy your new virtual DOS machine :)

This last command is an undocumented command that repairs the "Master Boot Record", that is, the sectors on your virtual hard drive that indicate which operating system is installed and so on. It seems that this is missing when you create a virtual machine via VirtualBox. Who knows.

Good luck!
