Help clockwork recovery prevents boot into os after flashing rom

[the anonymous]

I have attempted on multiple occasions to simply leave clockwork recovery without success. I have tried to flash roms from the external sd card to leave it, but whenever it reboots, it goes into clockwork recovery. It successfully installs the roms, but that's really all. It is also giving me these errors:
E:Can't mount /cache/recovery/command
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/last_log

Any advice/help on what to do would be great!
