How I Dual Boot Windows 10 and El Capitan 10.11.1 On HP Envy 4-1115dx i5-3317u HD4000

Hello all,

My daughter wants her Envy 4-1115dx dual boot with Windows 10 and El Capitan 10.11.1, so I used the opportunity to document how I dual boot this laptop. This one is exactly the same my Envy 4-1117nr and so many other HP envy with HD4000 - i5-3317u.

 

​1. I replaced her Ralink Wifi with BCM943225HMB 4357 wifi and 217d bluetooth.

2. To upgrade to Windows 10 from Windows 8.1 because of some stupid update failures, I had to create a new media win 8.1 USB installer -  Re-Installed fresh 8.1 and update straight to Windows 10 without any problems.

3. I used Windows 10 to create the El Capitan USB installer in case some newbies don't have a Mac handy. I'll post more videos as I go.

 

- Use Windows 10 to check device ids and RW Everything to extract ACPI tables (DSDT and SSDTs)

- Use Windows 10 to create El Capitan USB Installer with BootDiskUtility - Must have El Capitan 10.11 or 10.11.1 app or InstallESD.dmg

- Install El Capitan to External USB hard drive then restore to internal hard drive.

- How to patch IOUSBHostFamily.kext for USB ports on El Capitan - HD4000

-USB Ports Speed Test after Patching

- How to reformat EFI partition for Clover to boot - I couldn't boot from Clover because the Windows UEFI installer created a dos partition that's not FAT32.

- How to patch DSDT on Envy 4-1115dx

- How to generate SSDT using ssdtPRGen.sh from Piker-Alpha: Make sure you compile all the original SSDTs and put them together with this SSDT in the ACPI/patched folder for the powermanagement to work well... make sure the sortedorder in Clover config.plist has these files names.

 

 

Cheers,

 

Louis

Update El Capitan from 10.11.1 to 10.11.3 - Just need to reinstall patched AppleHDA.kext and IOUSBHostFamily.kext, sound and USB ports come back: bluetooth and camera.

 

Cheers,
