virtualbox.org

Hi, I'm preety new at this and i have a problem:
I earned a winxp sp3 image and I wanted to install it in the VB. The image was .mdx, and my linux didn't recognized it, so I turned it into an .iso. Then I just installed the vb, and mounted the image to install winxp (like I've done with different SOs), but when i try to boot the VB from the image, it just says: "FATAL: No bootable medium found! System halted.". It's like it doesn't even recognize the mounted image... If somebody could tell me what can be wrong i'd be really thankfull.
By the way: I have Ubuntu, and VBOSE 3.1.6
(sorry about my english u.u )

Are you sure that this .mdx file is truly an image file and that it is a bootable image file?
I looked a bit and it does not appear to be.

well, I know it is an image file, (the only thing i could find to mount it is daemon tools), but i don't know if it's a bootable image file... anyway, what i did was mounting the .mdx file in another PC with windows, took out everything from it, and made with it an .iso file, and that's bootable for sure... perhups that procces is not the correct to convert an image xD do you know how can i do that if that's the case?

oh, and sorry about the crossing-psot thing :S

The "No bootable medium found" message means what it says - there are no bootable disks selected in the boot order for this VM. So, either your virtual CD is not included in the boot order, or you have not mounted the ISO image as a virtual CD, or both of those are correct but the image is not in fact bootable.
