After Installing Windows Couldn't Access Partitions

my niece was telling me her dell was not working right so I decided to just do a clean factory restore as a scan with malware bytes revealed over 30 viruses/trojans! Someones gonna get a sit down to talk about her surfing habits but I digress. I figure at this point a clean restore is easier than trying to remove these viruses.

So I go to do the normal F8, repair my computer step and see that the repair my computer function doesn't work. Ok let me boot to windows 7 disk and select the repair option and use that for factory restore. Again nothing, usually Dell datasafe options will allow me to do this. I then notice that the recovery partition was not showing up.

I called her and asked and it seems my sisters so called boyfriends fancies himself a "computer expert" and last time they were having problems decided to just reinstall windows which I assume some how lost the connection to the recovery partition.

I installed EaseUS free partition manager and see that the Recovery partition is still there just not accessible. Is there a way I can make this partition bootable again so that i can assess it from the repair menu and possible repair this back to factory?

also if I go like im going to reinstall windows when it says in what partition you want to install windows I can also see the recovery partition.
