I did a fresh install, made with unetbootin on windows 7, USB 2.0 key (32GB) of Ubuntu 13.04 (64bit) install image, on to another USB 2.0 key (16GB).
In fact I did several installs, using default partition allocation and custom (selecting "something else" and allocating root and swap) but in all cases result is the same:
After prompt to reboot screen with flashing cursor comes up and then after a delay message (see attached screenshot) with the most important problem information in it being:
ALERT! /dev/disk/by-uuid/353f3494-0d06-4e7f-9e84-668893d2d1a0 does not exist,
Dropping to a shell!
I have attempted the boot-repair tool as per official tutorial using my installation USB key ("Try Ubuntu without installing"), it ran through successfully and produced following url:
however it did not resolve the issue.
Looking at the output and looking at the grub script (accessed at boot) I can see that uuid being referenced is a correct one.
However I do not have enough linux experience to even know if I am looking in the right places.
I have Gigabyte GA-990FXA-UD3 AM3+ MB with 8GB RAM, AMD FX-4300 CPU, Sapphire R9 280X video
As a background I installed Xubuntu 12.10 couple of month ago and it was working, then had to upgrade motherboard (to the one I have now) and the same problem happened. I do not remember what I did but somehow following one of the forums suggestions I fixed it. However so far 2 days of fighting on this issue did not result in the similar outcome .
The important part though is I do have a working 12.10 USB key xubuntu that works fine on this machine, so if there is something that can be taken/referenced from it to assist in solving this problem - I can get it.
Appreciate any help or suggestions...
