VERR_NOT_SUPPORTED appears when Windows 8 iso tries to be added

[Parker Young]

I tried to load the Windows 8 Release Preview x64 ISO file, and it came up with this error:

Failed to open the CD/DVD image C:\Users\Parker & Carmen\Downloads\Windows8-ReleasePreview-64bit-English.iso.

Could not get the storage format of the medium 'C:\Users\Parker & Carmen\Downloads\Windows8-ReleasePreview-64bit-English.iso' (VERR_NOT_SUPPORTED).

Result Code: VBOX_E_IPRT_ERROR (0x80BB0005) Component: Medium Interface: IMedium {53f9cc0c-e0fd-40a5-a404-a7a5272082cd} Callee: IVirtualBox {c28be65f-1a8f-43b4-81f1-eb60cb516e66}

Specks are the normal for Windows 8 x64. I JUST created the virtual machine. It won't take it. Help?

Have you checked the the SHA1 hash of the ISO is correct?

Ok, not to sound completely stupid, but how would I check the hash on the ISO file?

Oh! Actually, The x64 ISO I downloaded only seems to be 2 GB for some reason, even though it's supposed to be 3.3 GB. Let me try re-downloading it and loading it again.

use a downloadmanager like ​http://freedownloadmanager.org/ to avoid that the downlaod stops. Also check with tools like ​http://www.abelhadigital.com/multihasher or this ​http://code.kliu.org/hashcheck/ the hash.
