Public bug reported: I have tried to perform a normal installation of ubuntu 13.10 on a usb3.0 drive sandisk 16Gb, formatted ext4.
I do not how to provide you more information since grub does not even start and a violet screen hangs. I was suspecting a corruption of the usb mbr and I have tried updating directly the grub the I have on the hard disk used by ubuntu 13.04 and windows 7 with the key plugged in but again just violet screen and everything hangs. If I create a live usb in fat32 I do not have any problem. Could you please verify if there is a bug in ext4? Before on the same usb I had Ubuntu 13.04 but in UEFI mode since I was using a netbook UEFI. Now for sure I have a bios legacy and for this reason I have removed everything to reinstall ubuntu 13.10 in the mbr. The usb key has been formatted in gparted recreating again the partition table in msdos as follow: Le voci nella tabella delle partizioni non sono nello stesso ordine del disco.
