As RMT2 says, you need to be more specific on what your problem is. When you say you can 'get into the HDD part on computer' what exactly does that mean? If the computer only gets so far in booting then the exact point at which it stops is very important to diagnose the problem. Also a model number of your computer would be useful - we don't even know if you are referring to a desktop, laptop, or all-in-one.
