van_axl Posted January 3, 2018 Share Posted January 3, 2018 Hi Jake, I'm trying to make a new install for High Sierra on my E7250 (bios A17, FullHD intel 5500 display, i5), but for the moment I still can not boot with My Usb HighSierra stick. I did this stick with this post :https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-precision-xps-clover-guide/&do=findComment&comment=74275I've changed the EFI USB folder to the correct boot pack from here :https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-precision-xps-clover-guide/&do=findComment&comment=74275 I used the 5500 only pack as the 7250 has only one graphic board. But then while booting on my USB installer , in verbose mode, I got something like a kernel panic just when trying to boot.What step do I need to follow to troubleshoot ? Thank you, Van_Axl Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 3, 2018 Moderators Share Posted January 3, 2018 Can't help unless you post the full error. Boot with verbose + debug 0x100 Post screenshot of KP Your signature shows BIOS A13, try upgrading to A17 Link to comment Share on other sites More sharing options...
van_axl Posted January 3, 2018 Author Share Posted January 3, 2018 I had just updated my bios, and I forgot to change ma signature (now done). So I attached the end of the boot process Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 3, 2018 Moderators Share Posted January 3, 2018 I might have to repatch your files. Boot to CloverHit F4.Compress and attach your Clover folder But first try the Sierra Bootpack here Link to comment Share on other sites More sharing options...
van_axl Posted January 4, 2018 Author Share Posted January 4, 2018 Hi Jake, Thx for your help. I've tried both boot packs : E7450_HD5500_Only_A17_HS.zip & E7450_Disable840M_A17_HS.zip With each time folders & files removed (ACPI\ , kext\, and config.plist ) from EFI partition, before copying files. But result is the same. I attach the clover folder, after F4. hope this helps. Link to comment Share on other sites More sharing options...

van_axl Posted January 4, 2018 Author Share Posted January 4, 2018 Well, I did a new High Sierra installation, without formatting my Sierra drive. So I've kept all my stuff, settings ... And everything is perfectly working. Thanks again. Van_Axl Link to comment Share on other sites More sharing options...
