I tried to install OS 3.1.4. onto my Amiga 1200. All went well, I followed the disk prompts etc all the way through and at the end asked for the Install disk to be removed and to reboot the machine.
Once done, all seemed well until the Workbench popped up

And that's it

System is Amiga 1200, ACA1221 accelerator, 4gb CF HDD, 4gb PCMCIA which was running WB3.1 beforehand but have formatted and tried a direct 3.1.4. install with the same result.
Can anyone help?
Thanks.
