Try this, replace contents into /EFI/Clover E7450_Disable840M_A17_HS.zip

Boot to Clover, hit F4 at the GUI. Compress and attach /EFI/Clover/ACPI/Origin here for re-patching. The error means you need to disable the Nvidia card.

Can you enable the track stick too? I know your E7270 doesn't have it, but the larger E7470 does and it'll be nice to have it enabled.

Try upgrading to latest Clover

try this DSDT-E5440_sleep.aml.zip

attach IOReg IORegistryExplorer_v2.1.zip

Try installing in SafeMode

Try removing SSDT-2.aml and Drop TableID CpuSsdt in Config file

Does your model have the Nvidia card too? Cuz that's what you downloaded. If you only have HD 5500, you should use that instead.

Post the Clover folder

In that case, go to the install /S/L/E and delete all AppleIntelHDGraphics* Once installation is done, replace all the files including the patched FB

Your graphics is not loading. First boot with FakeID IntelGFX 0x12345678 until you could get to the desktop, you could then replace the correct Framebuffer. I believe you're still installing El Capitan? Go here, grab the first of the version of OS X you're install, replace it to /S/L/E Repair permission and rebuild cache. Just need the Framebuffer.kext

See here under NOTE1: Updating the Sierra Bootpack to be use for High Sierra You need to update the Config file and kexts, links included in guide

Great. You could start by going through that guide and see how far you go.

Looks like your system has the 1st generation HD graphics. I don't think your Nvidia card is supported so you'll need to determine if you'll be able to graphics acceleration on this system. See this guide to determine if you have LVDS or eDP connection. If you have LVDS, then it's possible with a few patches, if eDP you might get partial acceleration.

Do you still have Mavericks on the system? If so, run and attach IOReg IORegistryExplorer_v2.1.zip

check to see if you have CoreStorage. If so, you'll need to revert it to logical. See here

You can do that or boot with USB installer and select the newly updated OS X, then update the EFI partition

Reboot with the USB installer; at Clover, select boot MacOS install High Sierra since your old Yosemite doesn't have the updated files. Once installed, update the new files to the Installed EFI partition.

Try this Config. Your Config disables the graphics with fakeID. Make sure you're using the latest Liliu.kext v1.2.1 + IntelGraphicsFixup.kext config.plist.zip

See if this helps

You'll need Lilu.kext + IntelGraphicsFixup.kext in /EFI/Clover/kexts/Other

Which version of HS? Latest 10.13.2 requires latest version of Lilu.kext v1.2.1

What picture?? Nothing attached. See the FAQ for instruction on how to attach files to this forum

As I said, I didn't test for any ill-effect it might have. I've a better solution, hopefully it'll work for you too Restore all your vanilla files that you had replace. Then Inject custom EDID to fix the blank screen after wake from sleep See here for instruction I use "Apple MacBook Pro Display 16:10"
