[Solved] Crossed out Circle after MacOS Install (First Boot)

[silidor]

Hey, I'm trying to install MacOS High Sierra on my Computer.
I prepared a Usb Thumbdrive with the Installer (I followed the Guide with UniBeat)
I prepared my Bios Settings and booted into Clover and started installing Mac OS.
After that I rebooted my Computer and tried to boot into MacOs (first time)
It keeps loading but at 3/4 the apple logo disappears and a crossed out circle appears. I tried to boot in Safemode but It won't help. I tried to reinstall MacOS (HDD and SSD) but the result didn't change.
Can someone help me please?

i5 760 @3.6GHZ
8GB Ram

Boot in verbose mode and post a picture of the screen when it stops. (probably "still waiting for root device").

"Still waiting for root device".
When booting from USB means that there is a problem finding a valid System folder to start up from on your USB flash drive.
This is usually because the flash drive is in a USB3 port.
If this is the case move it to a USB2 port, if it is already in a USB2 port move it to another and try again.
Repeat until you have tried all USB ports.
Use a USB2 flash drive.
If it still doesn't work you could try another flash drive.
You might also try enabling Legacy on your USB3 ports in your BIOS settings.
Try connecting your USB flash drive using a USB2 hub.
Ensure that Fast Boot is not enabled in your BIOS settings.
May require USBInjectAll.kext in /EFI/CLOVER/kexts/Other/.
May require XHCI-300-series-injector.kext or XHCI-200-series-injector.kext in /EFI/CLOVER/kexts/Other/.
May need PMHeart’s patch to remove XHCI USB Port Limit in config.plist.

The problem may also occur when your USB controllers are unsupported, if this is the case you should add the appropriate kext to /EFI/CLOVER/kexts/Other/ or try GenericUSBXHCI.kext.

Oh btw. I should also mention that it once successfully booted into the Setup but then never again.

I dont't have usb 3 ports
It's a usb 2 Drive
I tried different usb ports => no difference

The fact remains :

Apple

Prohibitory symbol

When you see a circle with a slash symbol instead of the Apple logo, it means your Mac couldn't find a valid System Folder to start up from.

alright I put all those kexts in the folder you mentioned and tried to boot it again but it still doesn'T work

Sorry.. I am an absolute newbie...

In Clover I press Spacebar check -v and press boot MacOS with selected options.. thats correct right?

Have you set your hard drives to SATA not IDE in your BIOS settings ?

I just reread your first post and you said that you managed to install the OS :

After that I rebooted my Computer and tried to boot into MacOs (first time)

Are you able to boot from the USB ?

Should be in Sata Mode...
PCH SATA Control Mode is on AHCI
SATA PORT0-3 Native Mode is on Enabled
