Apr 27, 2015 1:56 PMby Bladeshard,I can try removing the bootcamp partition in Disk Utility and make a new one that can install OS X lion on it, just want to make sure with you before I make another mistake, you seem to be very educated with bootcamp and macs (was reading old threads of my same problem before and saw your name pop up) so thanks for the help!

OS X: Installing OS X on an external volume - Apple Support will let you install OSX on an external USB
- The steps in this article erase and reformat the storage device.
- Your storage device must have at least 13 GB available (after formatting) to install OS X Lion or later and a Recovery partition.
- This article instructs you on setting up a storage device to use the GUID partition scheme and the Mac OS Extended (Journaled) format, which are required to install OS X and a Recovery partition on your external storage device.
- You should back up any important files that are on the external storage device to a different drive.
- This procedure installs a version of OS X that is compatible with the Mac it was created with. Using this OS X system with a different Mac model may produce unpredictable results.
- Your computer's serial number is sent to Apple as part of this process to help authenticate your request to download and install OS X.

Apr 27, 2015 2:15 PMby Bladeshard,Great! Thank you so much, last question, when I would install windows 8 using the Bootcamp assistant when it reboots it asks me to load a cd or something like that in order to proceed and it was a black screen with white text, hopefully we are thinking of the same thing, but basically that led me to using efi in order to proceed in the installation by holding alt when I started up my computer and selecting EFI. There was no "windows" option there. And from what I read that makes it to a BIOS legacy instead of EFI so I can fix my audio issues.

Apr 27, 2015 2:25 PMby Loner T,Are you using a physical DVD for Windows installation? This issue comes up in one of two cases.
1. Physical DVD used for installation was burnt incorrectly (rate of burn is not supported by physical media), causing block errors on a physical DVD.
2. The ISO used to build the USB installer is corrupted during the download process from the source. The ISO can be validated by finding out the expected MD5sum/SHA1 from the source of the ISO using OSX (use openssl md5 command) or Windows (FCIV tool - https://support.microsoft.com/en-us/kb/841290?wa=wsignin1.0).

The startup disk cannot be partitioned or restored to a single partition.
The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows.

Apr 27, 2015 3:40 PMby Loner T,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.
