HP Z440 Windows 7 install Freezing on "Starting Windows" screen

HP Recommended
HP Z440
Microsoft Windows 7 (64-bit)



I'm trying to install Windows 7 on a new HP z440 workstation with a new 2 drive RAID 1 volume and the OS install is freezing on the "Starting Windows" splash screen.  This is booting from the OEM Windows 7 CD from HP for the z440.


Any help is greatly appreciated.

you will need to install the intel RST enterprise drivers during the setup using the F6 method of add new driver(s) to the windows setup program so it knows about the z440's hardware


the z440 uses the x99 chipset which came out after windows 7 was released as such there are no builtin drivers for this chipset, which is why you must add them during the windows install when prompted to add drivers via F6


all nessary drivers can be found on the hp web site for your model under the "drivers storage"  link, (click the " + ")


you need sp85585  


Intel Rapid Storage Technology Enterprise

system software Manager Icon Rev.A26.3 MB


use 7-zip/winrar to unzip the sp85585 package and use the  win 7 x64 folder files for F6


another link for the same driver package:


dbl click on the file and it will self extract to a folder named:




go into the win folder and then into the RSTe_f6_iaStorA_win7_64  folder,

copy those files onto a usb key  then insert the key into the z440 USB 2 port (you can not use a usb 3 port)

power on the z440 and when prompted to press/use F6 key point it to the usb key that has the files, then follow the prompts


rember you must copy all the files inside the RSTe_f6_iaStorA_win7_64 folder to a usb stick do not copy the folder
