vifer Posted October 19, 2017 Share Posted October 19, 2017 Hi , Ive been at this for two weeks now and cant get past the 'waiting for root device' prohibited panic symbol. Ive tried the guide here with the 6540 kext pack, all to no avail. My understanding is that the boot process cannot handover to the USB. Im trying to install Sierra but i guess I'll take anything at this stage. el Capitan, Maverick et-al. But i guess i have to fix my usb issue first. I've disabled USB 3.0 in the BIOS and did the usual AHCI switch in SATA. Ive tried all USB ports on the laptop including the esata\usb and also tried a usb hub. Nothing. Could someone please help. 1) What else is there to try? 2) How do I alternative boot\install apart from USB ? I dont have an esata ext drive , only a DVD player. my hardware is Dell Latitude E6540 BIOS A16 i5-4300M 2.6ghz 8GB Intel HD 4600 - 1920x1080 Series 8 - Haswell 256GB HD. thanks.

Moderators Jake Lo Posted October 20, 2017 Moderators Share Posted October 20, 2017 Does the system have dual GPU? Did you use the correct bootpack? Try using the eSATA/USB combo port to boot No need to disable USB 3.0 Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted October 20, 2017 Moderators Share Posted October 20, 2017 Try setting BIOS to load defaults, apply it. Then go back and set to UEFI AHCI Legacy Option ROMs enabled CPU XD support Enabled TPM disabled Secure Boot Disabled then try again. If still failed, attach the Clover folder for review Link to comment Share on other sites More sharing options...

Administrators Hervé Posted October 20, 2017 Administrators Share Posted October 20, 2017 Unless you're absolutely adamant on using Clover, you may want to consider the Enoch method... https://osxlatitude.com/index.php?/topic/7387-dell-latitude-e6440-with-i5-4300m-hd4600-and-1600x900-lcd-mavericksyosemiteel-capitansierra/page-3&do=findComment&comment=67673 Remember to double check your BIOS settings https://osxlatitude.com/index.php?/topic/9247-e6440-bios-settings/ Link to comment Share on other sites More sharing options...
vifer Posted October 22, 2017 Author Share Posted October 22, 2017 okay got further with Enoch and despite following the guide down to fine detail, I cant get the installation to boot by itself. it can boot with the USB key ( selecting the Sierra install at the boot loader ) but with the USB removed, it hits the enoch loader displaying the primary and recovery partition, but when I select the primary partition, it attempts to boot then it restarts back to the DELL logo. i tried installing, with ESP and MBR, and then UEFI ... no difference. tia btw, does the integrated wifi work? I couldnt see it in the devices. Link to comment Share on other sites More sharing options...
