Fatal : no bootable medium found . System halted .

[Ehab]

My host is windows 7 and my guest is windows XP. I just made the VDI file and trying to boot from the CD and I could not for the message :
Fatal : no bootable medium found . System halted .



though I used the same windows XP installation CD in the past.

What is it for a Windows XP CD? Is it OK? Does it boot on real hardware?

[Ehab]

My answer is yes . It is test on real machines . I enabled the option EFI and tried again but I have been faced with the message : Virtualbox has stopped again .
Here is the log attached .

Are you sure that the host cd is enabled in the vbox guest settings. It doesnt seem so.

Wasted effort. XP doesn't support EFI.

I don't believe that you have a valid setup CD, in fact I don't see any evidence in the log that you've attached either a host drive or an ISO file to the VM as a virtual CD. Just slapping a CD in a host drive is not enough.

I also notice that you've given the guest far too much RAM - you've given it almost your entire available host memory, leaving little headroom for the host. I would give it no more than 1GB (and in fact 512MB should be enough for an XP 32bit guest).

XP Does support EFI, when provided by OEMs as such. (Evidential by some Dell x86 machines using EFI and XP)
no retail or retail level OEM disk supports it however.
