Red Hat 7.2 install question

> Greetings --
>      I am trying to set up a duel boot system with Red Hat 7.2 and Windows
> XP.  All of the components in my system are fairly new (less than 6 months
> old).  I have formatted half of the 80GB drive and installed Win XP using the
> NTFS file system.  I have installed Red Hat 7.2 on the other half of the
> drive.  Here are some of the installation particulars:

>      1.  GRUB was selected as the boot loader.
>      2.  Boot loader record was installed on the first sector on the boot
> partition.
>      3.  Both GNOME and KDE were installed.

>      So far I have two problems that I was hoping someone might be able to
> help me with.  First, I do not receive a menu asking me which OS I would like
> to start?  I selected Win XP as the default and the system will boot to that,
> but if I want to start Linux I have to use the boot floppy.  Second problem,
> when I do start Linux it is in the text mode.  I have tried the startx command
> and also change the file /etc/inittab to read id:5:initdefault: to change to
> graphical mode but I have had no luck.
>      I have done a very limited amount of programming in the past and I have
