Daniele Sarnari Posted December 28, 2014 Share Posted December 28, 2014 Hello guys, Niresh Yosemite 10.10.1 is on an USB. My config: - Motherboard: ASUS M2N68-AM Plus - Cpu: AMD Athlon 64 x2 4850e - Ram: 4GB - Graphic Card: Nvidia GEFORCE GT-630(4GB SDDR3) With this flag the loading bar stuck at the begin: /amd With this flag the loading bar stuck at 40/50%: /amd npci=0x2000 I tried with different flag (/ AMD1, / amd2, / amd64 / amd32, / amd fx) but not even started booting. Only with /amd the boot start. What can i do? I tried also with the flag -f, -x, -s, GraphicEnabler=No. YOUTUBE VIDEO: http://youtu.be/vPIwaPK49ds WITH -S: http://i62.tinypic.com/9q9v20.jpg (stuck at Still waiting for root device) ERROR SHOW WITH -s: Link to comment Share on other sites More sharing options...

preciadoalex123 Posted February 9, 2015 Share Posted February 9, 2015 I get a similar result as yours, but my motherboard doesnt support ahci mode and im booting from a USB using an AMD kernel Athlon x4 640 with a GT 640 My motherboard is from Nvidia aswell (http://support.hp.com/us-en/product/HP-Pavilion-Slimline-s5000-Desktop-PC-series/4079861/model/4109919/document/c01925534/) my chipset: NVIDIA GeForce 6150SE nForce 430 many months ago i was using niresh's release on mavericks and it booted to the installer using -amd or -amd64 but im already using a amd kernel and im sure it works fine as im getting only USB problems not kernel problems, ive been looking for kexts to solve this but im limited on what i can do with a free account. im not using a 3.0 port as well.

markmiranpt Posted April 9, 2015 Share Posted April 9, 2015 Ok your probably maybe simple. Try putting your USB stick directly into a USB port at the back of your machine, and make sure it's not usb 3. That fixed it for me. I had the same issue. Let me know how you go.
