6230 Sierra install stuck on Language chooser

[jedko911]

Hi,

 

i followed guide from Herve to install Sierra on 6230.

Everything goes fine until i have to choose installation language.

When i choose language and click on forward arrow, i can see on menu bar only Language Chooser. No other choises.

Is there any workaround for this?

 

thanks

after succesfull installation, i can't boot to sierra.

When I use USB to boot and than select disk with installed sierra there is an error: Can't find bootloader - System/Library/Kernels/kernel

You need to follow the guide a little better: you did not check CoreStorage presence and you clearly have a logical drive in place.

Disk utility and other options in menu bar while installing is still not visible, but I can manage this with my old El Capitan USB installer.

 

Anyway, I can finally manage and get work Sierra, but...

I can boot to Sierra only with flag -f

When I try to boot without it, it hangs on this:

this is output with verbose flag:

any suggestion?

Download a fresh copy of Sierra installation app and start all over with USB installer creation.

 

If you boot with -f flag, kexts placed in /L/E will be ignored. You therefore need to load add-on kexts from /E/E with boot option KernelBooter_kexts=Yes. It's mentioned in the guide.

I copied all kexts from /E/E to /L/E and boot with option KernelBooter_kexts=No 

and it's working

 

thanks for your help
