Hard Drive Partition difficulties

I recently tried to install Windows 8.1 on my Mac Mini using Boot Camp but it failed. I tried to use Boot Camp Version 5.1.4 (500) to return my Mac Mini back to it's original state but received the following error...

Using Disk Utility I managed to remove a small partition created by Windows but was left with 1 partition...

My Mac Mini has a 1 TB hard drive but now it's 498 GB. I tried dragging the corner of the Macintosh HD in the Partition Layout ...

But when I click Apply I got this response...

Anyone know how I might get my 1 TB HD back?

Thank you.

Mac mini, Mac OS X (10.3.x)

Backup the drive, erase and repartition as 1 MacOS extended (journaled) partition. Then restore the backup.

Do you mean create an image of the drive? Also, if I erase the partition wouldn't that remove the operating system? How would I restore?

Thanks

You will need to use Time Machine and Backup and Restore your OSX which will restore the CS volume to the full size.

Thanks for the reply. I did as you suggested. I backed up then restored from Time Machine but this did not change my situation. Can you suggest a good free partitioning software?

Do not use a third-party tool for disk partitioning.

Can you post the output of the following Terminal commands?

diskutil list

diskutil cs list

sudo gpt -vv -r show /dev/disk0

sudo fdisk /dev/disk0

The "sudo" commands will prompt for your password, and it will not be echoed back. You may also see a warning about improper use of "sudo" and potential data loss due to "abuse" of the command.

Thanks but I did a complete re-install of the operating system. Everything is as it should be. Thanks again.
