OSX Installation Wipes My Whole Drive

[Pommy192]

Hello,

 

When I installed mavericks on my current PC, I made a 50GB partition on my hard drive (With an SSD for Windows) which was not formatted yet for the OSX installation. When i got to the disk utility settings on the installation, I formatted this 50GB space with the "Mac OS Extended (Journaled)" from the tutorial here: http://www.macbreake...ith-niresh.html

 

When i finally got the OS installed, I let it update ect and used it for a while, I restarted back into Windows 7. From here going to My Computer, I noticed that i couldn't access my hard drive and from here, All i could think is that the OS installation formatted my whole HDD loosing important data.

 

I managed to repeat this process with no important data that could be lost on an old PC with a 500GB for the current windows and made another 500gb partiton (which too, did not get formatted until disk utility setup) for OSX and this PC used 1 HDD and got the same results, the whole HDD got wiped.

 

I managed to install windows 7 on this old pc no problem with a OS selection screen on start-up, but what can I do to stop this happening in the future? (apart from buying a seprate HDD), as my friend wants to dual boot windows with OSX.

 

Mark.

you shrink the partition and format in OSX installer, not windows.

huh ... so you had windows 7 installed, then installed os x and everything is fine.

Then you start Windows (which seems to work?!) but your data is gone?

smells more like a user or windows problem ...

Wow that read hurt my brain. Just buy a seperate hdd. They are mega cheap these days.

In the disk utility, i selected the 50gb partition i made at the time and installed mavericks to that, for some reason, it formatted my whole HDD instead of the 50gb partition i made especially for it

You must've erased the whole drive, not just the partition.

[Pommy192]

I used "minitool home partition wizard" and made a partition of 50gb on the HDD, and selected this unformatted space (in the OSX Installer Disk Utility) to install mavericks which was then formatted as "Mac OS Extended (Journaled)"

I bet 10 bucks that you did (by accident) select the whole drive.

Oh lord, if you want to run both OS's off one drive you need to use Disk Utility in the OS X installer to create the partitions and then install each other to the allocated partition.

You have to install mac, then windows. Not the other way around otherwise that will keep happening.

PC, I think you mean your Mac? But then again both windows and macs are PC, PC as in 'Personal Computer'. First install OSX, then use Bootcamp to help you create a windows partition. It will also help you with the other preparations for installing windows. When it's all set reboot and it will boot from your Windows boot media. Install windows like you normally do and voila, dual boot. OSX and Windows.

You cant use bootcamp when on a hackintosh and there is no reason to. Since with a hackintosh you are using a custom bootloader, bootcamp wouldnt even work.

I thought he was using a mac not a hackintosh.

Nope

Figured out what happened, In order to install OSX, I have to make 2 partitions on the HDD in the first place to that "Mac OS Extended (Journaled)" and the second to a Windows compatible format (So i'm going to loose any data on the drive anyway). Another thing i missed out was I did not set it to GUID so i am unable to update to Yosemite as it needed this GUID partition thingy
