Messed up Grub

[douglas Pollard]

    I decided to use my sda and sdb drives as one drive. I tried to 
reformat my sdb drive using G-parted  screwed up and started 
partitioning my first hard drive. I stopped it, but I guess messed up 
Grub in the process.
     I get, ( Grub loading please wait error 22 ) message on attempting 
to load the original ubuntu program.  I needed  online help with this so 
I installed ubnuntu from a cd  on my second drive to get access to 
Ubuntu users group.  I believe my original Ubuntu is still on my first 
hard drive along with pictures and video but I don't know how to get 
back to it.  I would like to  get my original  Ubuntu up and running  or 
failing that  bring the pictures and video  to my new instillation.
     I tried to send this e-mail using the live Ubuntu Cd but 
Mail.Verizon.net would not let me send one for some reason?? 
    I am using Ubuntu 8.04 on a Hp dual processor AMD64 computer.
