USB Flash Will Not Boot - bad superblock

Reported by: Quantum Owned by:
Component: USB Version: VirtualBox 4.1.18
Keywords: raw usb boot Cc:
Guest type: Linux Host type: Linux


I installed Fedora Security to a USB stick, and confirmed that the USB stick boots fine to the laptop.

Then I set up a vm pointing to the USB device at /dev/sdb, as per instructions here: ... and it will not boot. Gets through GRUB fine, but when it tries to access the disk it says, "wrong fs type, bad option, bad superblock. UNEXPECTED INCONSISTENCY" and insists I run fsck. Rebooted and confirmed the stick boots fine, so I am not running fsck. Problem appears to be with vbox raw.

Host is Debian Testing.
