Comment 6 for bug 1549603

Using Ubuntu 15.10 fully patched but held back on older kernel due to problems with 4.2.0-19
Linux happy 4.2.0-18-generic #22-Ubuntu SMP Fri Nov 6 18:25:50 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

I attempted to blank the USB stick that I used to install 15.10 on this machine.
Startup Disc Creator complained of not enough space even after "Erase drive".
Gparted issued the attached error message.
The utility Disks only deleted a portion of the stick.
I used mkusb to wipe the first MiB.
Gparted then created a new partition formatted FAT32 (whole drive, 8GB)
Used Unetbootin to create a new bootable installer (Xubuntu 14.04 32bit)
It refuses to boot, error is "missing operating system"

This is day two of trying to do something that is usually very easy :(
