VirtualBox gives me this error message whenever I try to boot from my DVD-RW disc: "FATAL: Could not read from the boot medium! System halted.". And I don't understand why, 'cause I already burned my boot.bin file to the FULLY formatted DVD-RW disc, before I attempted the boot. It's just a test bootloader to print out "Hello, world!", and it works just fine if I just tell VirtualBox to boot from an *.iso consisting of this bootloader created with mkisofs. But as soon as I tell VirtualBox to boot from the host drive (MATSHITA DVD-R UJ-898) with the *.iso or just the *.bin file burned to it, it fails with the above error message.
But apparently VirtualBox considers my DVD-drive to be READ-ONLY. But if this is the case I just don't understand how OSX can burn the *.iso & *.bin file, and format the disc, without any problems.
I burned the *.bin (and in the first try the *.iso) by dragging them to DiscImageMounter in OSX, and clicking the "Burn" button.

Best regards,

Are you sure that in the burnt DVD there isn't the image file instead of the file of the bootloader and so on?

However, I recommend you to use Toast Titanium that works great. I use it to burn my os CD image and it works.

Yes, I'm positive that only the *.bin file resides on the DVD currently.
berkus, what commands?
EDIT: Would it work if I just got me some CD-RW discs instead?
