powermapler Posted October 25, 2013 Share Posted October 25, 2013 Hello, I'm currently in the process of my first Hackintosh installation, but have been stopped at the actual installation of the OS. The guide I'm following suggests that all data on my HDD will be erased, due to formatting incompatibilities between OSX and Windows. The current setup I'm using is an SSD as my Windows drive, with a supplementary HDD for data/games etc. My goal is to install Mavericks onto a partition of this HDD, which is currently sitting as unallocated space. Is this possible, without erasing any data on the HDD? Thanks. Link to comment Share on other sites More sharing options...
ameris_cyning Posted October 25, 2013 Share Posted October 25, 2013 1. Please post your full specifications 2. Is the drive MBR or GUID partition table? Link to comment Share on other sites More sharing options...

Open up Diskpart from CMD.exe and convert your hard drive to a GUID partition scheme Link to comment Share on other sites More sharing options...

ameris_cyning Posted October 25, 2013 Share Posted October 25, 2013 Is there no way to do this without losing data on the HDD? EDIT: Err I was wrong. Searching Google for a solution EDIT 2: Try this: http://download.cnet.com/AOMEI-Partition-Assistant-Standard-Edition/3000-18512_4-75118871.html Link to comment Share on other sites More sharing options...
powermapler Posted October 25, 2013 Author Share Posted October 25, 2013 EDIT: Err I was wrong. Searching Google for a solution Sorry, could you explain how to do this? My understanding was that in order to switch between MBR and GUID, all partitions had to be erased and reformatted, and Microsoft's support site reflects this. EDIT: Saw your edit after my post. Ok, I'll give that a go. Thanks. It worked! Thanks! I have my bootable USB drive ready -- do I proceed with the installation? Will there be an option to select the correct partition without deleting the rest of the data? Link to comment Share on other sites More sharing options...

Yes Open up Disk Utility and format that partition to HFS+ Link to comment Share on other sites More sharing options...
powermapler Posted October 25, 2013 Author Share Posted October 25, 2013 So, it looks like I don't have the option to do that. Apparently the disk needs to be repaired, but it won't let me do that either. This is what it looks like: http://i.imgur.com/BDHj0VW.jpg Link to comment Share on other sites More sharing options...

This is what it looks like: http://i.imgur.com/BDHj0VW.jpg Boot back to Windows. Format the partition as FAT32. Reboot into OS X install and try to format it to HFS+ again EDIT: Ensure that you have an EFI partition before the partition that you are trying to install OS X on. Ensure that this EFI partition is formatted as Fat32 and that it is 209MB Link to comment Share on other sites More sharing options...
powermapler Posted October 25, 2013 Author Share Posted October 25, 2013 It looks like the smallest I can make the EFI is 256mb. Is that okay? Reformatting to FAT32 did work, but I still don't seem to have the option to format it to anything else in Disk Utility. There is a partition option on the drive itself, but it seems I can't actually convert the partition to HFS+, unless I'm missing something.

Install this (its a 10 days full trial) http://www.paragon-software.com/home/hfs-windows/ Format the partition as HFS+. Boot into the installer and try to install on the partition Link to comment Share on other sites More sharing options...
powermapler Posted October 25, 2013 Author Share Posted October 25, 2013 I believe that program only works for reading HFS+ drives, not creating them. I couldn't figure out a way to format with it. However, I did realize what I was doing wrong in Disk Utility -- however, upon attempting to reformat, it tells me that there is insufficient space on the partition, despite it being 128GB. Quick Googling suggests that it has to do with a bad GUID configuration, but I have no idea where to go from here. Link to comment Share on other sites More sharing options...

powermapler Posted October 25, 2013 Author Share Posted October 25, 2013 Well, I was able to format the drive properly with another piece of Paragon software, but that didn't work either. I think I'm done for today, as I've been at this for about 6 hours now, but it looks like this has something to do with the EFI. I'll try to figure it out tomorrow. Thanks for the help!

powermapler Posted October 26, 2013 Author Share Posted October 26, 2013 Got it! I was able to use the MBR patch, reformat, and install from there. Booted with no issues. Link to comment Share on other sites More sharing options...
