Noob to Ubuntu and linux in general here so will need all the help I can get. I've just received very old toshiba portege 3480ct from friend and hdd on it has no os. I have an IDE adapter to usb and was wondering, can I install it as an external and then put hdd back into laptop? What can I do here? I tried but when ubuntu boots on old laptop when re-inserted as internal hdd, screen is all messed up and i can hear system loading forever. Any help would be appreciated. Thanks!
