• You should have started your own thread instead of posting to an abandoned post by somebody else.
• Your SHA-1 checksum 2c72b22a45ea8f5a80bee91db8aba96dae8310ea confirms you have a genuine full macOS High Sierra 10.13.4 (17E199) installer file.

tells me nothing!

• You may try to create a USB installer disk with the macOS High Sierra 10.13.4 installer file using CreateInstallMedia command on the Terminal followed by Clover EFI ( Preferably from RehabManClover_v2.4k_r4444.RM-4652.c1f8602f.zip) and editing CLOVER/kexts/Other with Essential kexts including Graphics support kexts for Intel HD Graphics 630 and editing its config.plist to use Intel HD 630 with proper FakeID and ig-platform-id with -v , dart=0 [√]-disablegfxfirmware
• You have to Remove your Evga GTX 660 ( please edit your profile to show the exact Graphics card) from the Motherboard PCIE slot and connect the Monitor to HDMI port of Integrated Intel HD
• You have to boot the disk using appropriate BIOS Options for Intel HD 630 Graphics
• You have to take pictures of Verbose boot screen(s) if boot problem occurs to upload to the Forum along with CLOVER from the USB disk as a zip file and the options chosen from BIOS for that failed boot to get good help.
