I am also having the same problem as febrile. I have downloaded the latest Ubuntu Netbook Remix 9.10, followed the instructions for building a USB boot disk and get the error "Can not mount /dev/loop1 on /cow" on my Asus Eee PC 4G.
I followed the instructions for getting the casper.log, have attached it to this comment and hope that it can help shed some light on this issue. ** Attachment added: "casper.log" http://launchpadlibrarian.net/40403500/casper.log -- casper-rw file not detected due to improper use of fstype https://bugs.launchpad.net/bugs/365853 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
