Macbook Tiger - First HDD full, ITune crush, now unable to boot

[soe_san]

MacBook OSX 10.4 <Dualboot> windows 7 RC


I have transfer some musics from friend Exter-HDD to iTune, about 20GB.
Half way the HDD is REALLY full and cant save anymore.
Next day I switched on and started using for other purpose, later turn on iTune.
iTune started to analyse all the music biliary.
Meanwhile I selected a song and tried delete using Comm + Del.
iTune crashed after I selected to delete the main file also.
So I shut it down.

Now I was no able to reopen it. always have white screen.

I booted with windows7, but windows bring me to recovery screen.
(now windows also does not boot any more)

What might went wrong?
How can I recover back?

thanks

You should not allow less than 10% of your hard drive capacity to be available as free space. If you do, then your Mac's virtual memory system will not operate properly and anomalous behavior may result.

You should boot your system from the System Restore disc or another bootable disc and remove enough files so that you are using no more than 90% of your hard drive capacity.
