[Q] Win 8, bypass PAE/NX/SSE2 check

If you patch ntoskrnl.exe only, you will have to press F8 followed by F7 on every boot to skip the digital signature warning. To disable the warning you have to run

Code:

bcdedit /set {current} NoIntegrityChecks Yes

and

Code:

RemoveWinloadPatchguard.exe C:\Windows\System32\winload.exe

 

Yes.......

 

If I burn the 'imagex.exe, install.wim and w8nxpatch.exe' files to a DVD or I run from another HDD, It's gonna work?

 

Jan, I just read your HowTo and here are few suggestions for other users:
1. If you will boot from W7 disk, you will not have bootsect command available. I suggest to boot from W8 WinRE (on another computer with NX support to prepare drive) (use C:\Windows\System32\recdisc.exe to create one within working W8 of same architecture (x64 or x32))...
2. For commands like:

Code:

bcdedit /set {default} NoIntegrityChecks Yes
bcdedit /set {current} RecoveryEnabled No

it will be necessary to point to store location like:

Code:

bcdedit /store W:\Boot\BCD /set {default} NoIntegrityChecks Yes
bcdedit /store W:\Boot\BCD /set {default} RecoveryEnabled No

(Both commands can be applied at once before installation.)

3. From within Windows DISM command below will give you number and description of indexes for various WIM files (Enterprise, Pro-VL, Pro-nonPro, etc...) (replace X with drive letter of mounted ISO),
so you will know which index to extract by imagex...
(W8ADK installation is required for DISM, command should be run from Deployment and Imaging Tools Environment (Elevated) prompt):

Code:

C:\Windows\system32\cmd.exe /k "C:\Program Files (x86)\Windows Kits\8.0\Assessment and Deployment Kit\Deployment Tools\DandISetEnv.bat "

Code:

dism /Get-WimInfo /WimFile:X:\sources\install.wim

 

So I have tested it with some legacy device from my computer graveyard (Acer Aspire 1600: iP4 3,06GHz HT, 2GB RAM, 2x 100GB HDD 7200RPM, ATi Mobility 9000 64MB, SigmaTel C-Major Audio, LSI Agere 56kb DialUp Modem, Realtek RTL8139 100MB NIC, Synaptics PS2 Touchpad, 4x USB2-0) and it works OK.

BTW: It was quite a lot of fun...

The most funny thing: Entire Windows Setup can be replaced by imagex-ing install.wim. That is really something.

Now Jan has a task to re-enable HT, hehe.

 

All fine. I'm used v1.2 and it works.

Thanks again.

 

Yep, but I discovered it right now...

 

I installed it and it's woking, but when I want to install an app I get this error: 0x80070422

I figured it out, the Windows Update service (wuauserv) was disabled. I enabled it and it's working now.

 

Guys, i have followed the tutorial very closely on a Latitude X1 but get a blue recovery screen saying i need PAE. did the patch only take care of the nx but not pae?

here's the specs on my proc

I have installed 8.1 preview using this on 2 old machines (Dell optiplex gx270 & HP pavilion 750n) and they are working perfect. They have P4 socket 478. I also updated them and didn't have to repatch. Nice work Jan1!!!

You must have PAE & SSE2 or this will not work

 

I am not too technical and if anything I'm more of an pre-Intermediate computer user and technician. Can I have some pretty simple instruction? Also, I've been wonder for awhile now....Couldn't there be a Windows 8 similar to the Consumer Preview which doesn't require an NX,SSE2 or PAE? Like a modified Iso. And if there is can someone get me a link? Well to be honest...If that was the case none you would be here finding a solution to your problem. Right?

I have a problem agian Yesterday it worked everything, but today I turnd on the pc and the windows 8 not loaded. It stuck at the blue logo without the spinning dots. I tried to boot win7 dvd for the command and tried to reapply the w8nxpatch.exe and removewinloadpatchguard.exe, but it says:
(w8nxpatch.exe): Error: No occurrences of the old value were found.
(removewinloadpatchguard.exe): Error: Unknown version of winload.exe

 

problem is coz ur winload and ntoskrnl are already patced
extrat new winload and ntoskrnl from iso and patch again
I had the same problem as you

 

From which iso? Could you send me the ntoskrnl and winload files?

 

open ur windows 8 iso with power iso and extrat boot.wim (now open boot.wim with power iso and find orginal winload ntoskrnl or what u need)
