- Unable To Find A Medium Containing A Live File System
- ACPI PPC Probe failed
And some other issues which aren't possibly related. The bottom line is that it wasn't possible to install ubuntu from USB disk as the live CD medium wasn't found.
There is an open bug with usb3 disks and I found that if I forced my laptop to treat the ports as USB2 (disable USB3 in the bios) everything worked fine. If you are having this issue and this post helps feel free to tweet me your dmesg issues so I can add them to the list!
