Bootcamp partition not ntfs

Thank you, worked well now

Sorry to reply to an older thread but you seemed to have found the same solution as I did. Everything you said was what I had to do, not use Bootcamp to create the partition, make free space in DU, etc. However, once I successfully installed Windows 8.1 and booted into it, I began installing the Apple drivers that downloaded onto my USB stick when I did the Bootcamp Windows install process. When I start that install process it freezes Windows on a black screen and I have to manually turn off and on the computer.

When it boots back up it just goes to a black screen and nothing else happens. I go boot back into OS X by holding option when booting up and selecting it. When I go into Bootcamp Utility again to erase the partition and restore all the space back to OS X it hangs and I have to restart again. Now I have this wasted space that was initially created for Windows that I can't erase or reformat. Any suggestions?

I'm on an iMac 5K.

Did you create your bootcamp partition using Bootcamp or through Disk Utility by creating "free space"? When I did it through Bootcamp it didn't allow me to install Windows on that partition, giving me the same error as your had regarding MBR partition tables and GPT boot disks. I was able to get it to recognize the Free Space I created using Disk Utility but then I had other problems. I guess I should try your precise ordering of things and also unplug my external thunderbolt drive.

This is so irritating especially after having installed Windows many times before on other Macs.

Can you post a new discussion and include 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.

Please download the following two utilities which can help diagnose and fix partitioning issues.

Testdisk is available at http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step.

GPT Fdisk is available at http://sourceforge.net/projects/gptfdisk/.

Here is the new discussion I made: Bootcamp Windows 8.1 Partition Problem

I haven't tried the two downloads you suggested yet. Thanks!

Not sure if this thread can be classified as old or why there are so many different solutions, but for me the way around the original problem was pretty easy on a Windows 7 boot camp install:

1. Go through the Boot Camp Wizard and let the machine reboot into the Windows installer

2. Observe the error message informing that you can`t install to the BOOTCAMP partition

3. Delete/remove the BOOTCAMP partiton

4. Install directly into the new freespace (Windows will make the partition automagically) or make a new partition from the free space and continue the Windows installation.

5. The boot camp installation wizard will start automagically when the Windows install is finished

The correct answer is on page seven of the Boot Camp instructions.

Well if that were the case this thread wouldn`t have been started in the first place. I tried doing only format and still Windows threw me the dreaded "Windows could not be installed on this partition" error message, however if I deleted the partition and recreated it everything went fine.

If you can't be bothered to read the directions that is up to you.

Good luck.

Mac models vary in these. EFI Boot will let you install Windows on Free Space and create MSR/MSD parts on a GPT-only disk if the Mac model is UEFI-compliant. Older models require Hybrid MBR which BCA can create or a set of manual steps can also be used to achieve the same goal.

GPT-only and Hybrid MBR are two underlying partition methods for EFI and BIOS installations.

Thank you! Even though I'm ready this 4 years later, this was exactly what I needed. I'm not 100% tech savvy, but I'm not an idiot. I just tend to overlook the obvious sometimes. That wasn't in any of the "steps" I read, so my OCD was reluctant to do more. Thanks again!

It's on pages 6 and 7 of the instructions. (as posted in this thread earlier)

This is exactly where I am. If I follow BootCamp and start to install, I reach the drive window and the BootCamp partition is shown. However, if I select Advanced Options and Format, then it's gone because it is not formatting properly. So, to get around that I boot to the Windows Disk and the USB drive takes over, but keyboard and mouse are not available.

I saw the same post that you mentioned, but I cannot find it. Can you provide me with a link please?

Thanks!

In Windows setup there is format link, select the BOOTCAMP partition and click on format; This will format the disk and then you can continue with the installation

This worked. The key thing was to uncheck the download stuff box from the bootcamp first page.

Strange, and thanks.
