Dell E6410 i5 and Lenovo L420 i5 Notebooks can't install Sierra


can somebody help me? I can't install Niresh Sierra software on both Notebooks as it is telling me "Still waiting for root device". I already changed BIOS settings for ACPI.

For my desktop PC with i5 processor it went fine.

Have you had any luck with previous releases of OS X on those notebooks?

Plus did you have an option to disable/enable VT-d in the BIOS?

Did you try plugging the flashdrive into another USB port and tried again?

Have you ensured that the flashdrive you're using can load the OS X installer?

Have you ensured that the notebooks you're using can boot from flashdrives/USB?

Did you try using the safe mode bootflag for the OS X installation (-x)?


I have found external assistance for the Lenovo L420 which seems to make for an excellent hackintosh judging by the fact that nearly everything works with El Capitan: https://www.insanelymac.com/forum/topic/320306-guide-lenovo-thinkpad-l420-with-el-capitan/

I found an El Capitan guide for the Dell Latitude E6410 but I suppose the guide can be used to get you into OS X Sierra without many issues (I hope): https://www.insanelymac.com/forum/topic/308765-guide-dell-latitude-e6410-nvidia-el-capitan-clover-eng/

You simply have to change the Boot Order in your laptop's BIOS. To access the BIOS, hit the F2 key right when you turn your laptop on (while the Dell symbol is still being displayed). The menu that loads is called the BIOS. Press and hold the ALT key, and press the P key to move through the menu pages. I believe it is the second page where you will see the Boot Order settings. Simply change the first boot device to cd-rom drive and then hit the ESC key and choose YES if prompted to save. Hit CTRL+ALT+DEL to restart your computer and try to boot from the CD. I highly recommend that you set the first boot device to your hard drive so that your laptop starts up faster. 

Check Dell Latitude E6410 Manual for more support.
