thank you Jake lo, I just found this out about my HP ENVY Dv7 7250us
it doesn't support AHCI instead with intel's RST software it runs the disks in RAID, dued to some technical issues.
my question to you, for a situation like this is there a workaround to install Macos
just to update, I've analyze the boot sequence, and I see something that says
kext org.rehabman.driver.FakePCIID.XHCIMux - library kext org.rehabman.driver.fakepciid not found
can't load kext org.rehabman.driver.fakepciid.xhcimux - failed to resolve library dependencies
kext ort.rehabman.driver.fakepciid.xhcimux failed to load (0xdc0000e)
failed to load kext org.rehabman.driver.fakepciid.xhcimux (error 0xdc00000e)
I added the file FakePCIID_XHCIMux.kext to the USB boot drive's clover>Kext>other but nothing happened, I don't know if I should install the boot loader to the drive itself and add it there, I don't think is going to make a difference. what do you suggest, and thanks for the help, I've been dealing with this for over a week now, is driving me mad, the funny thing is that I have a laptop with the same specs that my wife uses and is running apple's latest and greatest os and for some reason I can't get this install to recognized the sata controller or have the laptop's screen working, right now I'm able to see it because I have a external monitor connected to it.
this is what happens before the screen becomes garbled when booting from SATA
