Q: Win 10 installer on MBP2011 produces "couldn't create new partition" error

I'm trying to install Windows 10 on my late 2011 Macbook Pro. As it's not officially supported, I'm bypassing the use of boot camp assistant.

I have a 256GB SSD hosting OSX, I'd like to split that for Windows.

 

As I've read elsewhere, I created a FAT32 partition with diskutil command, set boot flags (as described here http://tinyurl.com/jrt9e2y), and fixed up GPT boot records (as described here http://tinyurl.com/l5q4tkt).

 

When I boot up on a Win10 installer usb drive, I select the partition, hit "format" to convert it to NTFS, and I get the error below. What can be done? Seemingly the installer creates its additional partitions, so I don't know why the error happens.20151229_001847.jpg20151229_005307.jpg

    There are two ways to install Windows, using Boot Camp Assistant or using a Virtual Machine. I suggest you go back to the site where they said you could do it otherwise and ask them for assistance and instructions.

    In addition to what BobTheFisherman correctly writes, also make absolutely certain you have complete backups of all of your partitions.

     

    You will want to generate those backups first, and then use the Apple Boot Camp procedures or use the procedures specific to whichever virtual machine you might have installed.  Or have a chat with the folks behind the directions you're following.   As was mentioned.

     

    Why backups?   Any partitioning-related failures here that might arise with any of the partitioning tools can potentially lead to disk corruptions and data loss.    Partitioning should be treated with great caution — when it goes wrong, corruptions and data loss can result.

     

    FWIW, OS X boot disks are almost always GPT-formatted.

     

    AFAIK, Microsoft Windows doesn't normally get installed on FAT32 volumes, and hasn't in many years.

    Exactly the same problem here. First I thought it was a issue of the latest Windows 10 iso. After trying everything to get it work, i decided to install windows 8.1 again and do the update from there to win10. But now i have the same issue when trying to install windows 8.1. I used the the latest bootcamp software to create the USB-Drive from an original image from microsoft. After booting into the Windows installer and after formatting the "BOOTCAMP" Partition created by the Assistant to NTFS via the Windows setup, i get the same error message.

    I made this Installation hundred times, so i know what to do. I think its an issue of the latest bootcamp software (6.0.2)

    At this moment i am unable to install any windows version. Always the same error.

    You have a completely different situation than does the original poster. You are trying to use Boot Camp Assistant, a supported method of installing Windows. The original poster is trying to install Windows not using a supported method of installation.

     

    You should re-post in the Boot Camp community located here: Boot Camp

    After extensive research, I see that installing Windows on a Macbook directly (at least on older models, without a dvd drive) is complex and tricky. Cloning a pre-made partition from a virtual machine is leaner and works universally for all models and Windows versions. This does not answer the problem above, and is not a direct alternative, but for most, it's a better solution.
