Windows 10 Boot Camp install won't let me install on BOOTCAMP partition on Mac Pro with SSD drive

I'm somewhere!

http://www.insanelymac.com/forum/topic/307408-cant-install-windows-with-bootcamp -fusion-drive/

kudos to Vizi0n, also thank everyone here, especially you Loner T. I tried to install windows 8, 8.1 and 10. All unsuccessfully. My solution was PRAM reset (cmd+option+r+p on mac boot, wait for second chime) when mac was in default state (only one partition not split !!!). Then I installed windows 8.1 as I was able to very first time. Important point was, after the PRAM reset, SSD (swap) was no longer visible in windows installer. Only disk0: 4 partitions:

EFI

Mac

Mac Recovery

OSXRESERVED with windows installer

goodbye endless nights

The SMC Reset and NVRAM Reset can be done at any time to clear the partition entries. It is good to see it working you wanted it to. Now you get to set up back ups for both OSes. 😉

Hi

After an partition crash I've re created the Fusion drive :

This solved my question Solvedby Loner T on Oct 8, 2015 2:24 PM

If you are in Internet Recovery, start Utilities -> Terminal.

1. Erase Macintosh HD volume - diskutil cs deleteVolume 0BD6E153-D4DC-4621-AD95-E0E36DDAFD87

2. Erase Macintosh HD volume group - diskutil cs delete C0A7D32A-D1AF-4A74-8E5C-D11CEEBB8F8B

3. Erase Macintosh SSD (this should be disk0, but verify) - diskutil eraseDisk jhfs+ SSD disk0

4. Erase Macintosh HDD (this should be disk1, but verify) - diskutil eraseDisk jhfs+ HDD disk1

5. Create a LV Group (the order of disks is critical SSD and HDD, in that order, please verify) - diskutil cs create OSX-MacintoshLVG disk0s2 disk1s2

6. Create a new Logical volume - diskutil cs createVolume <UUIDFromStep5> jhfs+ "Macintosh HD" 100%

Osx installation is perfect but I can't install windows. The error :

"We couldn't create a new partition or locate an existinge one... for more information, see the Setup log files. "

Just clicked on format on partiton 5 (bootcamp) and next . This previous message stop the process.

got an Imac 27 late 2015 1TB fusion drive. Can you check the fusion drive. I want it as new.

Can you start a new discussion and post the output of the command outputs? Are you asking how to recreate a Fusion drive or are you seeing an error when creating a partition for Bootcamp?

Happy new year 🙂

That's ok. The volume is ok. After an CMD P R its works. Osx and windows 10 are installed.

Still the last probleme (AMD RADEON error ).

Thank you so much

Which is on a different discussion... 😉

Sorry for disturbing this thread with different topic. However when you started, just three sentences: I accidentally uninstalled every AMD content (drivers, catalyst centre ...) last week. Automatic Windows update fixed everything out. Nothing else worked, this like a charm.

How do I get bootcamp 6.1 / AMD 15.201.2001.0 drivers

You did it___ what's you config ??

Your issue could be discussed in How do I get bootcamp 6.1 / AMD 15.201.2001.0 drivers thread. I answered there.

I had the same problem on both a 2015 MacPro and 2015 MacBook Pro. In my situation, I tried to load Windows 10 ISO using a USB Flash Drive - each time I arrived at Format BootCamp Drive it gave ne a NTFS error. Problem was solved when I downloaded Windows 10 ISO directly into my "Download" Folder on the Mac and installed ISO directly from Download Folder e instead of USB - this worked or both the MacPro and the MacBook Pro.

Hey Loner T, im having similar issues trying to run windows 10 i have MBP 15 mid 2010. stock 500HDD spinning disk and I'm currently running el capitan, i have the latest bootcamp and becasue i have a super drive it did not give me the option to upload the iso to the usb. i managed to fix it using Info.plist and using xcode. So now i do everything the way its intended and get to windows go though the installment windows, i get to the disk's and i see the bootcamp one i made and click it no next so i format it there and still no next just prompts me this. "windows cannot be installed to this disk the selected disk has an mbr partition table on efi systems. windows can only be installed to GPT disks." i tried not going though bootcamp and partitioning it by itself and still same prob. i make sure its on ms-dos (fat). Any ideas on what could be the problem? im loosing my mind here lol.

Thank you

You have two separate issues.

1. Your 2010 MBP does not support W10 officially. If you want to install it, burn the ISO to a physical DVD and use BC Assistant.

2. Your Mac does not support EFI Boot or installing Windows from a USB which explains the error message. BCA creates an MBR and W10 want to use EFI Boot.

I was trying to do what all the younger kids where doing with there new macs. This it worked like a charm burning the ISO to a DVD and the BCA to the flash drive. Thank you again Loner T.

Were you able to install Windows successfully, without any issues?
