Don't do it that way . The problem is 9.10 UNR has a bad usb- creator.exe. Like I wrote in https://help.ubuntu.com/community/Installation/FromUSBStick :
"Can not mount /dev/loop1 on /cow" message because usb-creator.exe is not creating a valid casper-rw file holding ext2/ext3 filesystem. Fix: After running usb-creator.exe, recreate casper-rw using cygwin tools or http://www.pendrivelinux.com/casper-rw-creator-make-a-persistent-file-from-windows/. -- Can not mount /dev/loop1 on /cow https://bugs.launchpad.net/bugs/492301 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
