are you able to activate find my mac when logged in.

it can also be you need CSM in bios or clover plugin.

have you tried logging in and out of icloud

ok so what drive location is windows located in. you can also try clover shell if it works EFI Shell command is bcfg boot add 3 fs0:\EFI\BOOT\bootx64.efi “Clover” if clover is on device fs0. You must then type bcfg boot mv 3 0 This second bcfg command moves your new entry to the top of the boot list

windows should be completely shut down/ powered off before starting or restarting your bootloader

i think 4049 clover installer has issues with the legacy boot binaries. you can try installing 3766 with it's installer then manually replace bootx64.efi and cloverx64 binarys. i guess save the 4049 binarys somewhere before reinstalling 3766 to have them available to put it back if efi is on disk0s1 you can try repair it with diskutil repairVolume /dev/disk0s1 in terminal

usually boot next will boot the last os it had ran so sounds normal. but since it is on 2 drives it could be that your bios chooses one drive over the other. your clover should be located at sata disk 0 drive and windows on disk 1 so if windows is disk 0 swap it's location with the other drive.

make sure your bootloader is up to date to handle 10.12.4

maybe your wifi switch is having issues or is set to off you can also try taping pin 20 on the wifi card

i recompiled the original code from here https://github.com/adlan/BCM5722D with latest xcode you can try it maybe it fixes your issue BCM5722D.kext.zip

how much ram do you have? maybe check with activity monitor whats sucking up your resources

try removing the ps2 kext in your config if you have a usb mouse and keyboard.

yeah that link is the LILU plugins page

what kext are you using for ethernet?

at clover prompt hit the spacebar and select boot in verbose mode it should display more info

looks like he set it to windows 2012

if the old screen had a higher resolution and the new one does not then you need to disable duallink, setting it to 0 instead of 1. or vice versa if the new screen is the one with higher resolution then it should be set to 1. if using clover it can be in either config.plist or if the DSDT was patched then it could be in DSDT

try repairing the disk with first aid from the recovery partition.

tried changing values of khz in midi setup prefpane?

is it these? https://github.com/vit9696/Lilu/blob/master/KnownPlugins.md

check bios for both issues. set sata to ahci and make sure lan is enabled.

hmm maybe it is osi related it seems that there is an issue with that card and sierra loading BT i came across this thread

yeah that seemed like a hardware issue or corrupted bios flash

you can try taping pin 51 like shown here https://youtu.be/Mw5HLg2rGuk?t=190

sounds like a bootloader install issue. what revision of clover are you using. also did you install it to the HDD your trying to boot if not boot from the USB select your hdd and hopefully you can finish the install. then install clover to the HDD. if you already installed clover then try see if you can select it in bios or in F12 bios boot menu.
