USB Flash boot copy to another USB flash
 

I have a USB flash drive, which is bootable and I would like to copy the whole drive to a different drive.

Can I just do a low level dd copy between both USB memory drives, or do I need to make an ISO of the source, and then put that ISO on the destination?

Thanks for answering the dumb question...I figured I could ask in less time than trying, and exhaustively testing to make sure I had it right...

Hi LB,
Not a dumb question at all. My guess would be the dd option but why not try that first and if it doesn't work, take the ISO route? It doesn't take much time and I don't see that you could do any harm. You're not changing anything on the original bootable usb stick.

If they are exact you should be able to dd it. I would not do a dd if they are not the exact model. An iso is not the correct choice. A clone of it using a clone app may also work fine. partimage or such should work.

Be sure you test first the new drive. May have to use hp tools or syslinux on it to get it bootable.
