(SOLVED)HP z800 failed to boot, after completed Ventura installation, and finally it's successfully with 13.4 & 13.6.

I created a bootable OS 13.1 USB's installation with OC 0.8 for my HP Z800. After installation completed, it rebooted a few time, After that it failed to boot up. I need help, if anyone has any suggestions. Thank you

Disconnect your USB 3 PCIe card, keep your system as simple as possible, and boot only from the SATA port.

I removed USB3 Pcie card, it still has the same problem.  Thank you for your response.

I know this is not the same machine, but the method of doing things is the right way.

After several weeks, I tried different EFI and Kexts. I have successfully install and boot Ventura 13.3.1 with my z800 with a fresh installation. It's every slow and boot loop some time. Safari doesn't work every well too.

First and foremost, I'd like to congratulate you on your successful installation. I can comment on your problem because I was in the same situation when I was attempting to install Big Sur, but it was my fault because I was attempting to install on a spinning drive, but I simply swapped to an SSD and everything was fine.

Thank you for your help, I have two installation one on ssd and other on spine drive both drivers working fine.

I found Kext from wannabe hacker,   https://www.insanelymac.com/forum/topic/356679-guide-installing-ventura-1331-on-legacy-775-asus-p5q-e-intel-q9650-geforce-gt-710/

 

NoAVXFSCompressionTypeZlib-AVXpel.kext 

 

telemetrap.kext 

FakeSMC.kext  preferred over VirtualSMC for legacy systems.  Also provides for better monitoring

and add on CryptexFixup.kext
