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&#x27;m unsure for the next steps.For my knowledge I will do the following steps to delete the volume group.diskutil cs delete&lt;UUID&gt;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,@elias

If you are in Internet Recovery, start Utilities -&gt; Terminal.1. Erase Macintosh HD volume - diskutil cs deleteVolume 0BD6E153-D4DC-4621-AD95-E0E36DDAFD872. Erase Macintosh HD volume group - diskutil cs delete C0A7D32A-D1AF-4A74-8E5C-D11CEEBB8F8B3. Erase Macintosh SSD (this should be disk0, but verify) - diskutil eraseDisk jhfs+ SSD disk04. Erase Macintosh HDD (this should be disk1, but verify) - diskutil eraseDisk jhfs+ HDD disk15. Create a LV Group (the order of disks is critical SSD and HDD, in that order, please verify) - diskutil cs create OSX-MacintoshLVG disk0s2 disk1s26. Create a new Logical volume - diskutil cs createVolume &lt;UUIDFromStep5&gt; jhfs+ "Macintosh HD" 100%7. Restore your TM backup.

Please backup OS X and Windows. Create a Windows System Restore point. Use separate external disks, if possible.
