In which order to go with El Captan + Windows (Legacy, BIOS)

Hello forum,
I already runned OS X Yosemite on my machine and wanted now to dual boot it with Windows and El Capitan.

My system:
- i7-920 @ 2,6 GHz
- Asus P6T SE
- 3x 4GB DDR3 Ram @ 1333 MHz
- Asus GTX 970
- 2x 1TB HDD

I'm running currently Windows 10 on the first drive and the second is just for storage.
So is it possible to keep my current Windows install and how I should get it done?
I only found some guides with UEFI Boards and completely fresh installs.. I already created the El Capitan Install USB drive with Legacy Mode but now dont know how to start.

Would be nice if someone could lead me in the right direction.. if I'm missing some information, please just tell.

Are you wanting to leave the Windows drive alone and install OS X on the storage drive or do you want both on the same drive? I would recommend separate drives - less when you go to update either OS.
If Windows is installed in Legacy mode, you will not be able to install OS X without reformatting the drive and re-installing Windows.
If Windows is installed UEFI mode, check the size of the EFI partition - if less than 200MB, much work is required via terminal to backup the EFI partition, delete the WinReTools, EFI and MSR partitions, create a new EFI partition in the space where they were and restore the EFI contents to the new EFI partition. Much easier to re-install.

Thanks for your respond.. So I formatted my disks yesterday, installed El Capitan (10.11.4) with UniBeast USB Stick with the installation Guide from tonymac and from this http://www.tonymacx86.com/el-capita...-se-intel-i7-920-2-68ghz-nvidia-gt-740-a.html on my first drive with the other HDD plugged out.

After installing Clover Legacy and CustoMac Essentials I restarted and booted without the USB Stick with boot flags '-v nv_disable=1'. Then I run Clover Configurator, created SMBIOS, set boot flags to '-v darkwake=0 nvd_drv=1' installed ALC110 Audio (answered everything with yes in the script), Nvidia Web Driver and then rebooted -> got AppleUSBUHCIPCI.kext panic and set Acpi exactly like this http://www.tonymacx86.com/el-capita...-os-x-el-capitan-x58a-ud3r-2.html#post1111697 -> rebooted and worked fine. Then I updated CommandLine Tools for Xcode (AppStore), set graphics to nvidia web permanently, installed a clover theme and rebooted, then I got the error below. Now I can't boot from my installed Clover in any mode, started now from the USB Clover which works but with slow graphics and no sound (don't know if audio worked before).

Reinstalled El Capitan -> installed clover, customac essentials -> reboot in verbose + nvdia disabled -> installed nvidia web, created in clover configurator smbios and acpi settings with verbose + nvidia enabled + darkwake 8 -> reboot -> works perfect

Installed WLA-2103 N300 Wlan USB Stick driver (newest for os x 10.8) -> reboot into stuck (screenshot above)
Booted with USB Clover -> Nvidia driver crashed while booting but el capitan worked laggy and the wlan driver worked too -> deinstalled wlan driver -> reboot with clover from hdd -> still stuck from above

So do I need another Wlan Card or what could it be?

http://www.tonymacx86.com/multi-booting/96000-guide-dual-booting-mountain-lion-windows-8-a.html should get you installed and running, although you will need to choose the Clover Legacy mode from MultiBeast for El Capitan rather than trying to use Chimera.

For the WiFi and GPU problems I don't know what you can do. Do you have the Clover graphics section set to inject nVidia? (set to true, rather than false? Are you injecting intel (default)?

I injected nothing, but got it running for now with WiFi and GPU working. I just reinstalled Clover and CustoMac essentials again, after installing WiFi drivers with some fails, but it seems everything is working fine.
Now I tried to install the ALC110 audio driver via clover110command, but it say's following after setting RtVariables -> CsrActiveConfig to 0x3:

File: audio_cloverALC-110.command_v1.0r10
Release Mode
Password:
EFI partition is mounted
System Integrity Protection status: enabled (Custom Configuration).


Configuration:
Apple Internal: disabled
Kext Signing: disabled
Filesystem Protections: disabled
Debugging Restrictions: enabled
DTrace Restrictions: enabled
NVRAM Protections: enabled


This is an unsupported configuration, likely to break in the future and leave your machine in an unknown state.

Glad you got it working. For audio problems create a thread in http://www.tonymacx86.com/audio/
