Hi Mike, good news, it certainly wont hurt to run "Startup Repair" again, what I would suggest is that you now backup your laptop first whilst it is ok, in case of future issues.
To run chkdsk from your boot disc select "Command Prompt" from the same menu where you found "Startup Repair" it's the bottom option. Then follow Mals instructions in post 63.
If your laptop is booting ok you can also access command prompt a number of ways but try this
Click the start orb, and in "search programs and files" type "command prompt" You will see command prompt at the top of the dialogue box, click on it as below.
The command prompt will open
Again follow Mals instructions in post 63.
"
Type chkdsk /r hit enter."
