sharmamadhus Posted March 28, 2014 Share Posted March 28, 2014 Hello Everyone, I am trying to install the Mac OS X Mountain Lion (Niresh Distro) 10.8.2 in my HP Probook 4540s but it gets stuck at "still waiting for root device". I tried various BIOS configurations and boot flags like debug=8, AHCIDisk=1, GraphicsEnabler=Yes/No, hp (this flag was provided in niresh's guide) and many others in different combinations but none seem to be working.Can anyone help me with this ?System :Intel® Core i5-3210M CPU @ 2.50GHz4GB DDR3 RAM (Single Channel)750 GB SATA HDDGFX-Intel HD Graphics 4000 @ 2 GBGFX- AMD Radeon 7650 @ 2 GB Link to comment Share on other sites More sharing options...
pokenguyen Posted March 28, 2014 Share Posted March 28, 2014 Plug it to USB 2.0 port Link to comment Share on other sites More sharing options...
sharmamadhus Posted March 28, 2014 Author Share Posted March 28, 2014 Plug it to USB 2.0 port Thank you for the reply. I tried booting it using EasyBCD as guided by "niresh" and also by a PenDrive by inserting it in USB 2 and 3 ports but none seem to be working. I think I am doing something wrong in the BIOS setting. Can you please tell me the correct BIOS configs, if you know ? Thanks again. Link to comment Share on other sites More sharing options...

pokenguyen Posted March 29, 2014 Share Posted March 29, 2014 What did you select? Link to comment Share on other sites More sharing options...
sharmamadhus Posted March 29, 2014 Author Share Posted March 29, 2014 I have formatted it again... now can you tell me what exactly should I select ? Thanks Link to comment Share on other sites More sharing options...
pokenguyen Posted March 29, 2014 Share Posted March 29, 2014 - From "OS X support kexts," select only the version that matches your laptop (4x30s, 4x40s, etc). - From "DSDT generator/patcher" select your "ProBook model," a "Fan behavior" that matches your preferences, and your "Display type." Note: you must select one option from each of the first three groups to generate a patched DSDT. In addition, you must have no DSDT present in /Extra/dsdt.aml at the time you run this option. If you wish to regenerate a DSDT later, you must remove /Extra/dsdt.aml, reboot, and then run the ProBook Installer using your desired DSDT options. - Check the option for "SSDT" generator. - From "System definitions," select ONE system definition which matches closest your laptop. - Chameleon: This allows you to boot from your main HDD/SSD - From "Optional hardware-specific fixes," - "EDID generator" Recommended. - From "Misc OS X fixes" - "Color profiles," Recommended. - "Sleep fix," If you have SSD, "Sleep image fix" is recommended. This disables OS X version of "hybrid sleep" where upon entering sleep, a "hibernation image" is written to the boot drive. For SSD, you don't really want to write this file every time your laptop goes to sleep. - "Extra tools" All optional. Select the ones you want. Try RehabMan guide.

sharmamadhus Posted March 29, 2014 Author Share Posted March 29, 2014 The RehabMan guide is what I used and got that above result. But now after re installing the Mac I am not able to use Probook Installer, it says installation failed. :/ What should I do ? I updated to 10.8.4 as the guide said...

pokenguyen Posted March 29, 2014 Share Posted March 29, 2014 You should download Mavericks 10.9.2 and try a complete new install. Link to comment Share on other sites More sharing options...
