Yes, you will need a new HDD.
You could also take the ISO with you and the shop could install that - asking them to change the product key to your COA sticker key.
If that works, that will save you from the expense of an OEM Win 7 install as MS no longer supply the retail version of Win 7 anything.
The shop may have their own way of reinstalling Win 7, but this method should it work and will be the least inexpensive - I guess it depends upon the integrity of the repair shop.
Licence keys for MS Office can be tricky when it is only a single licence key and will be rejected if used on another machine.
Have the shop look for the two MS Word folders as I've described and then they can be dragged and dropped back into their respective sections once Windows has been reinstalled.
To get it to reinstall, open the MS Word folder in Windows and double click on the batch file application and that will restore it.
I assume a HP preinstalled program as such should be pretty much the same as Toshiba have theirs, although HP from our experience seem to do things their own way
