Install Windows 7 on HP 800 DM G4

[Problem Devices]

Device PNP Device ID Error Code Not Available ACPI\IFX0763\2&DABA3FF&2 The drivers for this device are not installed. Network Controller PCI\VEN_8086&DEV_A370&SUBSYS_00308086&REV_10\3&11583659&0&A3 The drivers for this device are not installed.



presently, my HP 800 G4 DM setup is dual-boot. Win11 stays on WD SSD 512GB. Win7 is on Samsung SSD 256 GB. PC always boot onto Win11 by default. I would change to boot onto Win7 by default, how to do that? Thanks,

Here is mine. very similar to Win11's System devices (Win7 missing Hyper and V Virtual, two features)

for AC9560 WIFI, there are two solutions.

1. SIW2's suggestion, replace it. In my review, AC8265 is a good replace. Windows 7 driver exists.
2. Setup dual-boot: Windows 7 and 10/11 on the DM. when WIFI needed, boot onto Windows 10/11. I tested. worked great.

An ongoing annoying issue, MR image restore was stuck when WINPE starts, mouse/keyboard stopped working. a sign USB 3.1 driver missing.
but,
The Macrium Reflect rescue disk was made on this DM after MR install. no idea how USB 3.1 driver could be still missing.
in my next try, USB 3.1 driver was fed into MR rescue disk WIM. however, still same symptom when WINPE start.
At this time, Win7 and MR installed. I have a backup image from the DM but no way to restore on the DM using MR rescue disk.

Any idea?

Thanks,

I made a new MR rescue following your guide, updating the two *.msu and adding driver XHCI-UASPx64-SHA2

it still didn't work. mouse/keyboard stopped working when WINPE starts.

with same rescue, my tests performed on various gen,
on 6th/7th gen CPU --- Sky/ Kaby lake. no problem. boot, start. and mouse/keyboard working.
on 8th gen CPU --- Coffee Lake. no. it failed. tested on different USB ports. no luck.

During my running double driver, HP G3 7500T shows USB folder. while HP G4 8600 doesn't display a USB folder. it's unusual.
(i.e. the double driver failed to see USB folder on HP 8600. no its backup)






I will try this way. Thanks,

Update

hmm, bad luck. failed again. when MR WINPE starts, mouse/keyboard stopped working.

I tested various cases.
1st of all, tried your SIW2 WINPE/ 17514x64v30.iso. it run great on HP G4DM 8600. (the tool is really cool. it contains many apps, such as EasyBCD). mouse/keyboard were working fine.
next, run MR to make rescue disk, in advanced option, select to customize the wim and take the boot.wim from 17514x64v30.iso.

prior to this failure, on the G4 8600, I have tested Win7 (alone) and Win11 (dual-boot), made an MR rescue on either OS. however when boot with rescue USB disk, mouse/keyboard stopped working when MR WINPE started.
