Boot up issues

hi guys... k im having issues with my system.... problem started when i ran avasti and it said i need to repair windows xp pro.. so i tried to do that.. and now im in a kettle of fish... i managed i think to do a total reformat.. not happy but ok.. but i keep getting "floppy diskette seek failure press f1.. or f2..."

so im still not getting a full install of windows xp again.... and when i press f1 it repeats the windows install...

Please advise...
