bootloader boots from usb only

Recommended Posts

Hi,


I got a Samsung np300v5a laptop:


Core i5 2450m

hm 65

HD 3000 - works

Gforce gt 520mx - video not working

atheros 9287 - wifi works

alc 269 - audio works

focusrite scarlett 8i6 - audio works


My problem is that the bootloader boots from usb only. when i install chimera, chameleon or clover the boot will result in a bios boot loop.

i tried different versions of chimera and chameleon now. I also tried the boot1h thing for hds with 4k sectors.


I installed the Laptop with unishit, use MacBook Pro 8.1 smbios.plist. ssdt created by a tool of revogirl, dsdt modified by artur-pt, edited io80211.....kext, voodoohda for alc269,


Any ideas?


Thank you in advance!


Peace

Hi,


Here are the smbios.plist and the boot.plist.

I cannot make screenshots because there is no boot up. it will not come to the chameleon screen. It just flashes the lights two times after bios and then off.

Or do you mean the bootlog while booting from the usb?


Can it be that the bios somehow blocks the boot of chameleon? I updated it to the latest version before i started the hack.


Thank you very much for your help...:)

Is your HD partitioned as GUID or MBR?


Some BIOS only boot legacy (Chameleon) in MBR. To use GUID you must use UEFI boot loader (Clover)

Yes, it's possible to install on MBR, you just need 2 patched files

Like I said, this problem happens in "some BIOS". Most can boot legacy no matter what partition table you use.

Hi,


after the last days fiddling around with clover i can say a big THANK YOU!!!


Boot is working now thank your tutorial. It boots just from usb and from efi partition only, but am more than ok with the efi partition.

When i previously tested clover i thought its like chameleon...install and run. didn't work so i left it.

But now i know to have a proper config.plist and the right uefi drivers installed.

from here i got hints for the config.plist.

(in case it helps someone with a similar problem)


Thank you very much for your help to another step closer,

:)


Peace
