Dell Inspiron 8100 Dead Hard Drive

I replaced the original 20G drive with an 80. When I try to re-boot the 2 options I get are F1 to reboot or F2 for set up. I do F2 and I get to the set up page and it is locked up. I can’t move thru the pages. I hit F1 and it won’t re-boot. Despite the age I am trying to repair because my daughter bought this used from an Aunt with hard earned baby sitting money. Any suggestions?
