El Capitan Upgrade bootcamp not showing Windows 10

Hello Community,


For few days ago i have upgrade to El Capitan and the Bootcamp Software not recognize windows installation that i had already installed in Yosemite.


I'm able to choose the startup disk and windows 10 works without problems.

But if I start Bootcamp that tells me that there is no space to create new partition. So it not recognize that Windows is already installed.


Is there a way to tell Bootcamp that windows in up and work?


Here are the Terminal outputs:

1. Your Fusion drive seems to be configured incorrectly. It shows a 121Gb disk (assumed SSD) at index 1, it should be 0. the 750G disk0 should be index 1. Your OSX performance will be poor.

2. Your do not have a MBR, but it could be due an EFI Windows installation. What year/model is your iMac?

3. Please post the output of

diskutil list

sudo gpt -vv -r show /dev/disk0

sudo gpt -vv -r show /dev/disk1

You have two WindowsRE partitions (disk0s5, s6) which implies two failed attempts at Windows installation. MY recommendation is to backup OSX, boot into Internet Recovery, erase your internal disks, rebuild your CS volume correctly first with the SSD as index 0 and HDD as index 1, before you make another attempt at installing Windows.

Thanks,


I think I am going to do this in the weekend but I'm unsure for the next steps.


For my knowledge I will do the following steps to delete the volume group.


diskutil cs delete<UUID>


After than open disk utility and create a new volume group.


Can you tell me is this the correct way?


Second Questions: Is there a problem after creation to recover from Time Machine backup?


Many thanks for help,

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%

7. Restore your TM backup.
