I'm surprised hydrurga didn't catch this one. The "of=" part needs to be the path to the USB drive.

EDIT: The dd command you tried is like right clicking on the .usb file and renaming it with a .iso extension, no need to use dd when all you need to do in your example was to rename it.

Hydrurga didn't catch this one because OP originally gave no indication that he/she wanted to boot off the downloaded .usb in a VirtualBox VM rather than write it to a USB stick (which is where the .usb file is intended to be dd'd). Hence the note in post #2 "it may be something like sdb" and the comment in post #4 "how to install the .usb file to a usb stick". I was as surprised as others when it transpired that the OP wanted to actually boot off the .usb file as an .iso rather than write the file to a USB stick.

Hydrurga is therefore most sorry that he didn't anticipate this as a possibility and change the original Oracle-quoted dd command to "of=/dev/sdb" (although sdb isn't necessarily the USB drive which is why I recommended sudo fdisk -l to determine its actual device name). Although, in the end, it didn't matter, as it transpired that this wasn't what OP actually wanted to do, hence my post #6.

And, breathe out... ;-)

So...
What you are saying....
The OP could just burn it to a small partition or virtual drive "file" with dd, then mount that in VB and that would probably solve the issue?

Given the circumstances, I think the OP should take the path of least resistance and ask their friend to download the .iso version for them and use that in VirtualBox.

However, if I were in the same situation, I personally would at least try dd'ing the .usb file to a physical usb stick and launch a VirtualBox VM from it. I've never tried this before but there are instructions on the web on how to do it.

Interestingly, the x86 Live Media .iso on the downloads page http://www.oracle.com/technetwork/se...l-2245079.html is 1.1GB, while the .usb file is 1.4GB. Goodness knows why there is such a difference.

Damn straight!

Thank you soooo much dear friends. the command dd perfectly worked when i have changed the destination to physical USB stick. (And I had to run some extra commands to make vm run directly from physical USB stick (for the information, this is the command "sudo VBoxManage convertfromraw /dev/sdb ./usb.vmdk --format vmdk")
Finally I got it work because of you guys
Many thanks for all of you.
