1631991 Posted May 4, 2017 Share Posted May 4, 2017 Hello everyone, my first forum post here I am a totally newbie regarding Mac OS but I am willing to learn. Recently, I need to work with Xcode for school homework and sometimes I do them at home, without a Macbook. So, from a friend's story, I learnt that it is possible to install Mac OS X on a computer or laptop that runs Windows. I immediately started my research and intended to install Sierra on my old friend Toshiba Portege R705-P35, who has been with me since 2011, currently dual booting Windows 7 and Ubuntu 16.04.2. I began with this tutorial on WikiGain. I followed it correctly except for two things: I worked with Windows 7 Home Premium x64 and didn't add the Config.plist file as the tutorial suggested thinking it wasn't necessary because my laptop doesn't have a dedicated graphics card. I thought I was safe after getting into Clover's menu but eventually hit a wall. No matter what I tried, every booting attempt ended at "Still waiting for boot device" with a blocked sign and garbled text. My laptop's specifications (copied straight from CNET); Toshiba Portege R705-P35 Processor: 2.26GHz Intel Core i3 Memory: 4GB, 1,066MHz DDR3 Hard drive: 500GB 5,400rpm Chipset: Intel HM55 Graphics: Intel GMA HD (integrated) Operating System: Windows 7 Home Premium (64-bit) Here are what I tried: Changed SATA mode to AHCI and left it so for every later boot. Changed to another USB port. Unplugged then replugged the USB to the same port and to another port after the error message displayed. These boot flags (I don't know if they are relevant to my case but everywhere people suggested trying them so I tried): npci=x2000 -v -x UseKernelCache=No cpus=1 npci=x2000 -v -x UseKernelCache=No USBBusFix=yes USBLegacyOff=yes Recreated the bootable USB. As I don't have access to a Macbook, I can't try other solutions that require software which only run in Mac OS. From the message, I understand that somehow the installer lost contact with the USB mid-installation and failed to continue. As I observed when I replugged the USB, its light flashed for one second then immediately went out. I used a brand new Gigastone U207 USB 2.0 Drive so I don't suppose the problem is with the bootable USB itself. Any suggestion is much appreciated.

Thanks in advance Hi, If I understood correctly, you tried to boot OS X without a config.plist in your clover folder? That's like removing a resistor from the mother and *expect* it to work! It might work, but it won't just work. So, start by putting an appropriate config.plist in the clover folder. You can use config.plist of other Laptops as long as the configurations are close. Regarding "Still waiting for root device", you can try removing graphics related kexts from the USB Installer. Basically any kext that starts with AMD, ATI, NVDA, GeForce and AppleIntelHD.
