having difficulties installing Ubuntu onto ASrock Probtc H81

[Rooothlespredators]

I have had a lot of trouble installing ubuntu via usb drive onto these motherboards. What keeps happening is this error

Somebody suggested passing this into the kernel line

init=/bin/sh rw

that caused this error

Failed to execute /init (error -8 )

and another kernel panic.

Have you tried Googling or asking in the Ubuntu forums to find a working install guide to USB for your version of Ubuntu?

[Rooothlespredators]

I had a similar problem a while back with an ASUS Z97-A  mobo where the content on the USB-stick would get
corrupted.  I managed to fix this by turning off USB 3.0 mode in BIOS, then I had to reinstall the OS to the USB stick.
