wanted to make a system install to USB pendrive, but aborted it. Now it wont boot at all , but i managed to check out what may be the problem with the help of uart and the following came out:   Gave up waiting for root device.  Common problems:  - Boot args (cat /proc/cmdline)    - Check rootdelay= (did the system wait long enough?)    - Check root= (did the system wait for the right device?)  - Missing modules (cat /proc/modules; ls /dev) ALERT!  UUID=e59363f1-765c-4660
