Why do you want to write registry keys?

 

Can you give an example of  an registry key that you would want to write ?

 

Also would this registry key and value change depending on the computer or is it always a fixed value ?

 

If you just want to write a registry key/value in boot.wim without modifying it, there may be others ways. You dont necessarily have to use Grub4Dos to do that for you.

Thank you, can you help me?

 

for example

 

I start from win 7 pe

 

I want it 1 registry key when the boot record

 

key = HKLM \ Software \ BkavPro

name = P2P3

type = REG_SZ

data = enable

There is a way of 'injecting' the registry entry on each boot - are you booting from a removable USB flash drive?

[TrungNT_HUST]

yes !!! So should my work or use as USB or CD \ DVD

[steve6375]

If booting from a removable USB flash drive to WinPE v2/3/4, you can place an AutoUnattend.xml file in the root of the USB drive.

When PE boots, it will read the XML file.

Look at Tutorial 43 on my site for the menu and autounattend.xml file  (au.xml)

So using this mechanism, you could script reg or regedit to run and add a regsitry entry to the PE registry when it boots.

However, this may be too late to take effect (it depends what reads the registry entry and when it takes affect).

I don't know of a way to do this from GRUB4DOS without writing a Microsoft Windows Registry driver, but for 2000, XP, Server 2003, an NtBootDD.Sys "driver" could do it. (My WvBootDD could have a feature to do it, using the functions inside NtLdr.)

NativeRegMod can write to registry during booting. With some modification it could be recompiled to a driver too I suppose. But if all this makes sense, is not yet clear to me.

I use windows 7 pe !

 

I still have the first questions people wish to help.

 

Why do I modify the boot code path but it can not succeed

map -- mem (md) 0x800+4 (99)

write (99) [BkavAuto]\nEnable=installdrv;\n\0
