Ensure that you are using the latest version of Dell Backup and Recovery 1.7.1.2: [URL] Once you have the latest version (which should fix this issue) remake the recovery USB and try again.
just got a dell 1531 and am having trouble getting win 8.1 to reinstall on a smaller hard drive. i have the usb stick but it then says i need the same size hard drive that the factory reinstall was taken from. is there a work around? thx
