Help Mount Unmount and auto detect new partition and restore of Grub

[José Paulo Matafome Oleiro]

Hi there people, I've got few problems for you to help if you want and
can help me. I've deleted my windows partition and installed Debian to
take a look but Debian doesn't had the version of kernel that I need so
I'm gonna stay with Ubuntu as the only operating system installed at my
laptop, but now if I delete de partition of Debian, my computer just
gives me error because I had installed grub from the Debian installation
in the MBR (Master Boot Record) and now if I delete the Debian
partition, Grub gave me errors I think it's error 21, so how I can
reinstall Grub in the MBR with the menu.lst from de Ubuntu system, and
after this I will create a partition with the free space from the Debian
installation with the filesystem ReiserFS and then I want this partition
to be detected my Ubuntu, but now that I had installed Debian, it only
shows to me in System > Administration > Hard-Disks, the NTFS partition
of my old system Windows that now doesn't exist and the partition of
Ubuntu and Swap Partition, can you help me with this little problems?
Thanks for your help in advance.
