you need to change the boot order in the bios
make the 190 meg boot partition bootable
you can use the install dvd ( but this is a live cd so it is limited )
pop it in and from the menu select "boot from hard disk"
you can use it to run
there should be a " * " asterisk next to the /boot partition
I like "Gparted live cd"
and in the gparted menu make the boot partition as a bootable device
and are you sure that grub installed to the /boot partition because you said you installed it to " /"
