I am currently trying to install setup Windows XP SP1 as a guest operating system in virtualbox, however I receive this error when trying mount an iso of the install cd I have.

VD: error VERR_NOT_SUPPORTED opening image file 'File path goes here' (VERR_NOT_SUPPORTED).

I have tried installing through a USB CD drive and through an iso of the same CD but I receive this message.
I have also tested the cd/iso, which runs with no problem in virtualbox on a Windows 10 PC.
The latest option I have tried is creating a VHDX file of the OS installed on a computer. When attempting to use this file the same message occurs.

I am currently running the latest version of virtualbox and OS X El Capitan.

Does anyone have any idea about why this file would not work on Mac but would in Windows?

When quoting an error message it would serve us all better if you actually "quoted" the whole message accurately, not substituting parts of it, like 'File path goes here'.

• How did you create the ISO?
• VHDX is not supported by VirtualBox.
• See Minimum information needed for assistance. As far as the VBox.log.zip goes, here's what you do:
  • Start the VM.
  • Record the error message. EXACTLY. Post a screenshot if you have to.
  • Shut down the VM.
  • Right-click on the VM in the VirtualBox Manager.
  • Select "Show Log..."
  • Save it, ZIP it and attach it in your response.

Here is the exact error message I am receiving:

Failed to open the disk image file /Volumes/Untitled/OS Files/WinXP_SP1.iso.
Could not get the storage format of the medium '/Volumes/Untitled/OS Files/WinXP_SP1.iso' (VERR_NOT_SUPPORTED).
Result Code: VBOX_E_IPRT_ERROR (0x80BB0005)
Component: MediumWrap
Interface: IMedium {4afe423b-43e0-e9d0-82e8-ceb307940dda}
Callee: IVirtualBox {0169423f-46b4-cde9-91af-1e9d5b6cd945}
Callee RC: VBOX_E_OBJECT_NOT_FOUND (0x80BB0001)

I don't have a log file to generate because this is happening during configuration, before the VM starts.
I created the iso using dd in terminal and a second time using Mac's disk utility to image the cd. Both iso's generate the same error message.

Then maybe there's something wrong with "WinXP_SP1.iso"? Are you sure it is an ISO file? You could try this from the terminal:

file /Volumes/Untitled/OS Files/WinXP_SP1.iso

Here's what I get for example with one of my bootable CDs/DVDs:

file clonezilla-live-2.4.2-61-i686-pae.iso
clonezilla-live-2.4.2-61-i686-pae.iso: ISO 9660 CD-ROM filesystem data '2.4.2-61-i686-pae              ' (bootable)

BTW, what's the filesystem of your external hard drive named "Untitled"? Is it maybe FAT? How big is the ISO supposed to be? Something does not compute. Are you sure you're not forgetting any minor details?

I would suggest that you check the MD5 sum for the ISO. I have no way of knowing how much validation checking the host software does - so displaying the directory is no guarantee that the whole ISO is ok, but an md5 sum is definitive.

After many of the recommendations I began looking at the MD5's and the the iso files that have been created in various different ways. It looks like this is an actual issue with the iso file itself. I am not sure where the issue is stemming from since I used disk utility to image the cd to and iso and used dd to do the same. I am going to take this back to square one and work on imaging a correct form of the installer cd.

Thanks for all the help everyone.

FWIW, I'm missing something. If you still have the .iso that installed on your Windows 10 host it would install on an OSX or Linux host. If you don't still have it, you could always copy the working VM from your Windows 10 host and add it to your OSX host. Unless of course you don't have a drive large enough to copy to.

The OS I am trying to install is a old copy of Windows XP that I have. I have the disk, which I know works because I was able to install it on an old machine I had lying around. The issue is with the .iso file I am creating from this disk is not being created properly and can't be inserted into the virtual disk drive during the VM's setup. My assumption is that something is going wrong during the iso creation process, I am just not sure where the flaw is because I have done it about 10 different ways now.

I have also tested the cd/iso, which runs with no problem in virtualbox on a Windows 10 PC.

Which one had no problem, the cd or the .iso?

Since apparently your Mac has a CD/DVD drive, did you try installing from the XP CD directly? You would have to select your Host CD/DVD drive as the Optical Drive and enable Passthrough.

My Mac doesn't have a CD drive, I was using an external DVD drive connected to the Mac. I tried connecting through the host with a pass through but was getting a completely different error message there.

I was able to figure out the issue, it boiled down to the iso file. For some reason using Mac Disk Utility, dd terminal, and Burn were all generating iso's that wouldn't load. I finally gave up, installed imgburn on a PC, a burned the cd to an iso file, and it is finally working.

Well, not sure what the issue was. I just installed Windows 7 directly from the install DVD and I have made a working .iso with Disk Utility from a Super Drive..

Anyway, glad you have it working.
