Hello, I had the same problem, too, installing Linux Mint 17.2. The installer just crashed, informing me that it had crashed, and not giving massively helpful error messages.
I don't like having to trash the contents of a usb stick in order to install an os, so I have one usb stick created under Linux with good old grub1 (or grub4dos) on there. My problem was that I had not copied these directories to the root of the usb drive: /preseed /.disk /dists /pool The whole usb stick is mounted under /cdrom on the resulting live system, and some or all these directories being in the root directory seem to be immovable. It's unfortunate that all these files, only amounting to 8.2MB in total on Mint 17.2, and 5.6MB on Ubuntu 15.04 can't all be more portable and placed anywhere. It's unfortunate, too, that after years of bug reports, the error handling on this is unhelpful. It seems to be an upstream ubuntu problem, though. To fix, this is what I did, assuming that the usb stick is mounted under /usb: #Mount the iso image as a loopback on /cdrom mount -o loop linuxmint-17.2-cinnamon-64bit.iso /cdrom cd /usb mkdir mint17.2 cd mint17.2 #Copy all CD files to /usb/mint17.2 rsync -avv cdrom/ . --progress #Now copy the necessary dirs to the root of USB: cd /usb rsync -avv /cdrom/preseed /cdrom/.disk /cdrom/dists /cdrom/pool . --progress My grub1 menu.lst command line is: title Linux Mint 17.2 kernel /mint17.2/casper/vmlinuz file=/mint17.2/preseed/linuxmint.seed live-media-path=/mint17.2/casper/ ignore_uuid boot=casper ramdisk_size=1048576 root=/dev/ram rw splash -- initrd /mint17.2/casper/initrd.lz The same idea can be used for Ubuntu 15.04. Grub4dos also works for booting usb sticks.
