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

1) Both EFI partitions displays very similar structure if not the same.

2) Yes it does. It creates 4 partitions in total which one of them is MSR (16MB) and then throw different error. Let me do this again

I asked Microsoft support and they instantly denied any help since realised I'm Mac user. I contacted MS support 3 times, two chats, one call. No-go.

I do have new error now:

"Windows could not complete the installation. To install Windows on this computer, restart the installation."

This is new! I'll check other forums.

I'm sorry I didn't wrote the error message correctly. (I didn't wrote it down and then tried to remember searching for similar msgs)

I did csrutil disable and checked next reboot so it is really disabled

precisely the error message is: "Windows could not prepare the computer to boot into the next phase of installation. To install Windows, restart the installation."

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.

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

Most definitely, i was able to install Windows successfully, without any issues. The audio driver Realtek install got stuck on the install with BCA but i fixed it just by reinstalling it manually. To save some headache in the future, is there any good tips or suggestions on drives and or programs or a list of recommendations?.

Please create a backup of OSX, Windows and create a Windows System Restore point. Windows Updates should be manual to avoid incorrect drivers begin pushed to the Mac. You should periodically scan for updates and apply them selectively based on your specific needs.

I am having the same issue the OP described, however I have a late 2015 27" Retina iMac with 1TB SSD, not the fusion drive, running OSX El Capitan 10.11.3 and BCA 6.0.1(522). I've disconnected all external drives and I still get the same error as seen in the video linked earlier in the thread. I only have disk0. BCA installs OSXRESERVE on partition 4 and BOOTCAMP on partition 5. When the Windows installer asks me to select the drive to install on, I select partition 5 and the error message says that Windows 10 cannot be installed on the drive because it is not formatted NTFS. Formatting the partition using the Windows installer doesn't help either as I receive another error that the selected drive cannot be used.

I miss the days of "It just works".

Hi Loner T, Have a similar issue here whereby the installation of Bootcamp was unsuccessful.

Having booted mac to OS X and attempting to remove the Bootcamp partition, the option was not there.

Booted the Mac into local recovery and there were four partitions present, Mac OS X, Bootcamp, 1.16GB partition and a 16BG partition.

Ran first aid on the Mac HD and Erased the Bootcamp Drive Partition - 16GB partition diappeared once the Boot Camp partition was removed.

The drive was set back to Mac HD (one partition)

Checked with diskutil cmd to see if LVG is okay -> no LVG found

Tried /sbin/fsck -fy -> getting: volume is mounted with write access. Rerun with -l to freeze volume

Rebooted the mac and now the Mac Pro has a flashing question mark and will not boot.

Single user mode is not working either.

Any suggestions most welcome.

Hi,

Im trying to install windows 10 and when I get to the install and the format partition to NTFS part, when I click it, it doesn't seem to do anything and won't allow me to click next. It says, windows cannot be installed on partition 4.

Hi Loner T, I've been having similar problems and attempted PRAM boot as suggested however after that my video has gone, then after about 10 seconds into the boot it shuts down. Attempted all forms of reboot and nothing is working. No idea what has happened and the timing for this has been terrible with work deadlines approaching. Thanks

Can you check for any unknown devices in Device Manager?

Excellent, now you get to start regular backups of OSX, Windows, etc. .

I have this issue on my 3TB fusion drive.

tried for 3 weeks to get win10 or win 8 to install. nothing works. so im waiting for apple to FIX bootcamp.
