virtualbox.org

I have successfully installed Virtual Box Version 2.0.0 on a ubuntu Hardy system.

VirtualBox recognized the VM I have been successfully using in VMware and I have added the VMDK file as the IDE Primary Master using Virtual disk Manager. The VMDK contains a Windows XP Pro x64 installation.

When I start, the xVM Virtual Box Flash displays, then tries to boot.

It fails with this message:
FATAL: No bootable medium found! System halted.

If I select F12, none of the choices there works any differently.

Does anyone have experience with this scenario? I really hate the idea of creating another VM, installing and setting up an XP environment again.

It seems that there is no MBR in the file. You can try a fixboot and fixmbr from the XPx64 install disk recovery mode.

I just went ahead and created a new guest and installed XP in it. Boy does it run better than VMware!
