Hello my name is federico.

I decided to try freebsd. I have exhaustively read the handbook about the installation, I read other books too.
I read www freebsd.org/doc/en_US.ISO8859-1/books/handbook/install-trouble html too

I have a 180GB disk. With the blank disc im installed Windows XP on a 40GB partition. Later im install FreeBSD on a partition of 50GB. Im accept the default geometry setting of sysinstall.
After the installation restart the PC. The boot menu says:

windows F1
freebsd F2

Or something like that, but I'm sure did not say F?

But when pressing the keys does not boot, none of the 2 systems.

What could be wrong?

Thank you very much.
