windows 7 starts with an error report

hi,can anyone help me to get windows back on to my imac.,i have a problem with uploading windows,it starts with an error report saying there is a problem

and gives me two options the 1st it tries to repair the problem and then tells me it cant repair it and when i click finish it closes down,the 2nd option

is start windows normally but when i scroll down to this option nothing happens.i used to have parallels but got so frustrated at this doing nothing i removed it

from my imac,but that did not help,can anybody help.
