Okay, I'm gonna start from the bottom here to make it simple and try not to make it boring.

My MacBook Pro is stuck in infinite loading times, when you see the white apple logo and a little spinning loading thingy. Also, I have bootcamp installed with Windows 7, same problem persists, also just loading forever. Here's what happened in steps.

1: I was having an english class, I opened my dictionary and I had pages open, suddenly the computer stopped responding.

2: I restarted the computer, but Finder did not work properly, I couldn't use the computer, there was no finder bar.

3: I booted up in safemode and it started working (for a day).

4: When I again got the problem, I booted up in Windows, which was working perfectly, but a bit slow. I fell asleep so the computer ran out of battery with a usb stick in it.

5: The Windows part now got a bluescreen of death for 1/2 second and then restarted.

6: I went back to try and fix my mac side of the laptop, I held shift on bootup to go to recovery, to discover a "Reinstall Mac OS X" button. I pressed it, and it said it would take 9 hours :O

7: After that was done, my Mac OS worked again (only it was incredibly slow), but Windows still didn't work.

8: I fixed the problem with Windows by booting up in safe mode a few times (I had to do it a few times because it still got the 1/2 second blue screen even though in safe mode)

9: I finally got into Windows in safe mode and decided to ask Windows to go back to the last "functional" time or what it's called. That worked! Windows now worked again, but it was so slow that I couldn't use it at all.

10: The laptop got so slow that I had to shutdown the computer by holding the power button, then the load times were infinite! on both mac and windows.

Notice: I did not know if this was important, to begin with, I thought I burned the RAM because I had custom 16gb ram in it. I changed it back to the original 4gb ram, but it showed no change... at all.


It's a:

MacBook Pro 2011 (I think)
i7 processor
16gb/4gb RAM
Intel HD 3000 GPU
500 gb harddisk

That's all I can tell you specification wide. Thank you for taking your time to look into my problem

It sounds like a failing Hard Drive. If you haven't done so already, I recommend you back up all your files ASAP, even before troubleshooting because if my suspicions are right, that thing is on its last legs.

After you back it up, see if a spare hard drive allows it to work any better, or see if a friend will quickly place their hard drive into your laptop. That's a good way to troubleshoot. If you can confirm that the issue is a failing hard drive, you might not have to buy a new one (but it's probably just easier to do so anyway). They're usually around $60 - $70 for a good laptop 2.5" HDD, but repair options are sometimes available if you're skilled enough or the problem isn't too serious.

Hm, but "borrowing" a friends harddrive would work? It's on a Mac, so first of all it needs to be a Mac harddrive? Or will it just like boot in Windows? I really appreciate your time and trying to help me :D

If anyone has another solution please shoot.

Is there such a thing as, just buying a new one like the same and switching it? And how do I backup my harddrive when I can't access the computer?

Bare with me here:
Can I just, connect a SATA from the harddrive to my desktop computer and copy everything, then buy a new one a place it in the new harddrive and poof it works?

Are you entirely sure this is the harddrive?

There's no such thing as a "Mac HDD" really. All the parts inside a Mac are the same as they are inside a Windows PC. A Mac's hardware truly only differs in I/O ports and, if you hate money, in resolution (i.e. Apple's retina display). But the basic parts are still the same as any PC.

However, I wouldn't recommend putting an HDD with anything except OS X into your Mac Book because we're trying to troubleshoot here, and even though an HDD with Linux or Windows could potentially work easily, the conflicting drivers that were preinstalled are more likely to make the troubleshooting task difficult and could cause other unforeseeable issues. But if it comes down to it, you can go ahead and put another HDD with Windows 7 or 8 on it, and it wouldn't be any permanent detriment to your machine.

----------------------------------------------

For the post you wrote just as I finished typing what I wrote above the line, yes you can just hook up a SATA cable and go for it. However, that's only if your desktop is using Mac OS X. If it's using Windows, you can do the same thing but you'll need another program to access the Hard Drive since Mac OS X uses HFS+ file structure while Windows 7 uses NTFS. This is an article on HSFExplorer and how to use it:
http://www.pcadvisor.co.uk/how-to/windows/3369574/how-read-mac-os-hfs-drives-in-windows-for-free/

As for buying a new hard drive, yes, it's that simple. Mac OS X will automatically format an HDD for HFS+ upon install. Just make sure that it's 2.5". If you can find one and it's in your budget, I recommend you find 1 that's 7200 RPM, though if you can only stick to 5400 RPM at 2.5", that's fine too.
