Alright, you might be in luck then.
First let me explain why you have to do it this way so you understand.
A bios password ***** NOTHING to do with your hard drive, windows, etc. It is actually stored in the systems hardware (cmos/motherboard). They used to have bypass codes back in the day, but now most manufacturers just tell you that you need to buy a new computer or motherboard if you lose the password.
That is the case in some situations. The aspire series though, you can reset the bios by clearing it's battery.
Here is a video doing this procedure:https://www.youtube.com/watch?v=aNR7JZYl2PE
Be careful, work slow, and follow the video. It's not a difficult procedure in this series luckily, most laptops are far worse at getting to the cmos battery (some are impossible due to being sodered in).
As for your disk error, it's likely booting to the wrong device, or your hard drive failed which is why it's not booting to windows. Even with a bios password, your system should still boot to the drive as long as it doesn't have a boot bios password (which it doesn't, or it would say so instead of directing you to bios setup with F2).
