Administrators Hervé Posted January 24, 2018 Administrators Share Posted January 24, 2018 Look up JakeLo's generic guide for Latitude / Inspiron /Precision / XPS guide in the Guides->Dell forum section. Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted January 25, 2018 Moderators Share Posted January 25, 2018 what version of BIOS are you on? Do you have UEFI and AHCI enabled in the BIOS? Boot to Clover GUI, hit the F4 key on the keyboard. Compress and attach the Clover folder here for review Link to comment Share on other sites More sharing options...
sunilkumar Posted January 25, 2018 Author Share Posted January 25, 2018 BIOS version is A22UEFI and AHCI are enabled Nothing happens after pressing F4 Unable to attach file after several tries. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 25, 2018 Moderators Share Posted January 25, 2018 F4 will silently extract the raw DSDT/SSDT to /EFI/Clover/ACPI/Origin, usually within a second. Did you compress the folder first? Click on the FAQ on my signature for instruction to attach file(s). Link to comment Share on other sites More sharing options...
sunilkumar Posted January 26, 2018 Author Share Posted January 26, 2018 Attached Clover folder EFI.zip I had deleted \EFI\CLOVER\themes Because I am facing problem in uploading the compressed file size of 8.4MB Link to comment Share on other sites More sharing options...
