Hey, Similar problem here. My HDD is completely full (accidentally) and now it will not turn on at all, which makes sense as there is no room for anything. When I try to boot it up it just stays on the loading screen. Is there a way for me to delete some file say the trash so it can boot. Options that I have been think of: 1. If I can get in to Terminal from Install Utility (if it has one?????), I then can empty the trash. 2. Boot OS X from another HDD plugged in to it and then some how accessing the original HDD and deleting some files. Can someone confirm weather this is possible or anything I can do if at all. Unfortunately, if is my home computer which my wife is using and I am away so can not ticker and fix it. Or even pull the HDD out and plug it into another computer to delete some files. Thanks.
