Hi cast-fish
I'm going to go a little off topic for a minute....
You say you can't enter boot codes and in another thread mentioned only 4 keys on the keyboard
work. That suggests a laptop with an external USB keyboard that's not recognized until after booting
is complete. If you can get into the BIOS and change settings, try changing the USB Legacy setting.
If you can't do that, but the laptop has a mini DIN connector for an external keyboard, get a USB to
DIN adapter, that's what I use for my mouse.
Back on topic, I have to agree with Guy, sounds like you made a mess, best you clean out your
tce directory and re-install your apps.
