Jun 22, 2015 3:35 PM in response to Loner Tby AndreaTD,I bought it in 2010, a MacBook Pro 10.6.8. Not sure about the second question, I will know it tonight for sure, but maybe I was selecting the 64-bit option from the list of available versions.

Jun 22, 2015 9:26 PM in response to AndreaTDby AndreaTD,So, I was trying to start from the beginning and take the screen shots. I deleted the previous partition download and now I got one more problem:
"This disk cannot be partitioned because some files cannot be moved. Back up the disk and use Disk utility to format...."
Almost all my space available has been used for the previous partition even though it was deleted. Now I cannot even do a new partition. I didn't want to back up the system, so I follow these steps which I found on the web, but it didn't work:
"I was facing the same problem with my MacBook Pro. I used the following method and it resolved the issue. I hope that it works for you aswell.
- 1. Go to Disk Utility and erase free space on Macintosh HD (which took about two hours for me).
- 2. Restart your Mac and boot up by pressing CMD and R.
- 3. Choose Utilities, then Disk Utility in the menu and then Repair the HD.
- 4. Restart and then try partitioning using Boot Camp again."
Well, not my lucky day. I will be going to the genius bar Tuesday evening bar to see if they can do something about it.
Thanks for your help Loner.

Jun 23, 2015 4:28 AM in response to AndreaTDby Loner T,This problem is fairly common and occurs due to fragmentation of the internal disk, irrespective of whether it is a HDD or a SSD.
1. Reset SMC and NVRAM and try BCA again.

How to Reset NVRAM on your Mac - Apple Support
2. Boot in Safe Mode - https://support.apple.com/en-us/HT201262 and boot normally and try BCA again.
3. Backup and restore
a. Back up OSX using Time Machine - Mac Basics: Time Machine backs up your Mac - Apple Support.
b. Boot into Internet Recovery - OS X: About OS X Recovery - Apple Support.
c. Erase your internal drive and restore from the TM backup in Step 1 - OS X Yosemite: Recover your entire system.
Please be aware that TM does not backup Bootcamp partitions.

Jun 23, 2015 4:44 AM in response to Loner Tby AndreaTD,I will need to buy an external hard drive to be able to do Time Machine backs up. Thanks Loner. Andrea

Jun 23, 2015 5:03 AM in response to AndreaTDby AndreaTD,Do you recommend any specific external hard drive? I was thinking to go to Staples and Best Buy and check one of 1 TB. Andrea

Jun 23, 2015 5:46 AM in response to AndreaTDby Loner T,★HelpfulMy suggestion would be to consider two separate 2-4TB drives. One for OS X/Time Machine and another for Windows/Backup & Restore.
A single disk with formatting for both OSes, can lead to some complications.

Jun 24, 2015 10:28 AM in response to Loner Tby AndreaTD,Hello there,
Before closing this post I am going to tell you what happened at the end with my problems and it may help somebody else. About the issue with the backup, it was not required. I followed those steps and I was able to recover my free space after uninstall Windows 8 without formatting or back up my system (however, it is always a good idea to have a back up in some place):
1. Switch off computer
2. Switch on and keep pressing command key+ S key.
3. After the writing stops, add: /sbin/fsck -f and press the enter key
4. If appears "File System was modified", enter /sbin/fsck -f again. If not, skip this step.
5. If you see "volume appears to be ok", write exit and press intro. Wait for reboot and check your free space available.
About my other problem, after the computer reboot, I should have wait and reboot a few more times and then key pressing the option key during the last reboot to get to choice between MAC or Window system. After choosing windows you write your name and password, etc.
Thanks Loner. Regards, Andrea

Jun 24, 2015 10:36 AM in response to AndreaTDby Loner T,Glad to see the fsck worked. . Thanks for posting back.
The procedure you used is documented in Resolve startup issues and perform disk maintenance with Disk Utility and fsck - Apple Support .
Safe Mode is also supposed to execute the same as using a manual Single-User Mode (Command+S) and the fsck.
What is safe mode?
Safe mode (sometimes called safe boot) is a way to start up your Mac so that it performs certain checks, and prevents some software from automatically loading or opening. Starting your Mac in safe mode does the following:
- Verifies your startup disk, and attempts to repair directory issues if needed
- Loads only required kernel extensions
- Prevents Startup Items and Login Items from opening automatically
- Disables user-installed fonts
- Deletes font caches, Kernel cache and other system cache files
Together, these changes can help resolve or isolate issues related to your startup disk.
