Do you know why I have one Macintosh HD and one Macintosh HD2 partition beside the Windows one, when I start the Boot-Manager? Did Carbon Copy Cloner did it, or even Boot Camp? It must be some kind of a Recovery partion.
I believe it was never visible before. I realized it, when I tried to disable SIP for a moment. Many thanks.
Can you provide a screen shot of what you're seeing?
Thanks a lot. One more thing I just realized: I get a rotating globe when I boot into Recovery mode.
If you're booting into the Recovery HD (Command+R or Alt key) but getting a spinning globe that usually means your Recovery HD is missing or corrupt and it's booting into Internet Recovery instead.
Open Terminal and type diskutil list and diskutil cs list. Post the results of those here. These should show us if you have an Apple_Boot Recovery HD slice.

I assume this is a Mac Mini with a 120GB SSD and 3TB HDD fused into a Fusion Drive?
I have asked Loner T in the Windows Software Boot Camp forum to help you. He might have had experience with this type of issue with Bootcamp users and Fusion Drives. And he might be able to get things sorted out. I don't want to lead you into reinstalling OS X El Capitan and potentially mess you up more. Make sure you have a recent back up of your system in case you have to restore something.
You have

This is your Recovery HD.

What is the version of Windows you have installed or want to install? What is the OSX version? What is the year/model of your Mac?
SIP is disabled only in Local Recovery (boot using Command+R) using CSRUTIL command.
It's Windows 10 and it's installed. I am on OSX 10.11.3. It's a late 2014 iMac with FusionDrive. I can't disable SIP, it tells me that this command is not known. I think I am not in the right Recovery. Many thanks for all your help.
Your local recovery may be corrupt. Please back up OS X and Windows, and create a Windows System Restore point. Once completed, if you re-install OS X, it will leave your non-OS files untouched and rebuild OS X.
The Local Recovery being corrupt may put you into Internet Recovery which will install the shipped version of OS X, not the currently installed version. In this case, install OS X (older version) on an external disk, and upgrade it from App Store to the current version. This should also give you a Recovery HD on the external disk. Use this to rebuild your internal disk's Recovery HD.

Many thanks for your advice. One question: Will I loose any of my data when doing the recovery from the local partion or from the Internet? Thanks again.
Best practices usually recommend a backup prior to such significant changes. It is safer, even though it may take longer to execute the backups.
Installing OSX on an external disk is relatively low risk, but choosing the incorrect partition can lead to catastrophic data loss. Rebuilding the internal Recovery HD is relatively a higher risk step and should be executed after backups have been created.
Sorry me again. Before I start the procedure one more question. Can I simply download El Capitan from the AppStore and reinstall? Would I loose all data or would that just repair the system? I just realized that I have a Carbon Clone Copy on an external drive. Can I use this?
Apologies for my lack of knowledge and many thanks for all your effort!!
Yes, you can re-install El Capitan from the App Store. A backup is still highly recommended. Do not erase the partition.
How old is the CCC on the external drive? You also need to be careful, because you have Windows.
Apologies for my lack of knowledge and many thanks for all your effort!!
No worries. I was not born with OSX in my DNA either. 😉

Three, by my count. 😉

Yes.

When reinstalling, you can choose to wipe the disk (via Disk Utility) and cleanly reinstall (possibly migrating data in from backup), or you can choose to install OS X over OS X. The former clobbers the disk and everything on it. The latter probably works fine for most cases, but you will still want an external backup or two, as mistakes and errors and disk failures can happen.
I'd generally create a bootable USB device from an App Store download, as that's faster to use, handy to have around in general, and you can do that download while working on other tasks and can easily tell when it's all downloaded rather than watching that globe spin. Internet recovery progress tends to be rather more opaque.
I just realized that I have a Carbon Clone Copy on an external drive. Can I use this?
As....? A source for migrating in the data? As a backup? Sure. I'd probably want a couple of external copies, as I'd prefer to have one copy entirely disconnected from the Mac while I'm wiping disks. Mistakes here can be... data-destructive.
Given how hosed the configuration seems to be, I'd likely use Disk Utility and wipe the disk using Disk Utility (from the bootable installer), reinstall OS X, and then migrate the data in from the backup — basically treating this like you just got a whole new Mac, and are migrating your data from your old Mac. From your corrupt environment, in this case.
Whatever you're using to back up Windows, back that up here, too.
FWIW...
Here are the Apple notes on the Fusion Drive for your iMac.
The last CCC was made approx. one week ago. Do you think I can use it? A TimeCapsule backup is not very usefull here I guess? I have one but it will recreste the issue again - I think.
If I would reinstall EC from the AppStore, would it just "repair" the system and keeping all data intact?
Many thanks from Europe!
A TM Backup for OSX is very useful. It will be an incremental backup, if you have had a previous backup on the same TM device or TC.
TM does not backup Windows, so an erase of Fusion drive/restore from TM implies losing your Windows installation.
Your Fusion CS LV/LVG look fine. The Recovery HD is where your issue lies.
I have two Macintosh HD partitions - why?
