I now have a window that reads:
Continuing will remount your / fillesystem in read/write mode and mount any other filesystem defined in /ect/fstab. Do you wish to continue ?
I replied Yes and now I have under it:
fsck from util-linux 2.20.1 /dev/sda: clean 318818/10117120 files, 24047888/40467456 blocks .
It been like this for 3 hours how should it take?
