Windows 7: problem dualboot vista and 7 winload.exe error

problem dualboot vista and 7 winload.exe error

First of all sorry for my bad english (i'm italian) but on any italian forum no one can help me.
I have installed on a second partition of my first hard disk seven (in a first partition I have vista). The first start of 7 goes well and I can see the desktop without any problem. Then I restart my pc to change the boot priority and set the hard disk as default. Then I restart again and I see the vista boot manager that ask me to select the os to start. When I select 7 I get an error that say:

FILE \windows\system32\winload.exe

Status: 0xc0000428

info: windows cannot verify the digital signature for this file.

(I think that is the english version of my error, the code match)

I try to repair the windows starup with the wizard on 7's dvd but it doesn't work. I unistall, reburn, reinstall 7 but the result was the same.
If I open (when I running vista) the property of winload in 7's directory I see that the digital signature of the item doesn't match (a screen of property in italian: http://img29.imageshack.us/img29/5007/catturahw.jpg)

Please help me in a basilar english, thx a lot in advance

Welcome to Seven Forums.

What graphics card are you using?
Do you have on board graphics?
Take the graphics card out if you can.
You might try getting the latest graphics card driver and loading it during the install.

Another option might be to check for the latest BIOS update.

What speed are you burning the DVD at?
What program are you using?

Try installing with a USB Memory key, min 4GB. You can find a good tutorial here.
USB Windows 7 Installation Key Drive - Create

Run the Windows 7 Upgrade Advisor found in this tutorial How to Use Windows 7 Upgrade Advisor

It might find something.

Let us know your progress.

Ciao Milite, benvenuto (that is all my Grandma taught me...)
Pls try what Dave instructed, and also check if your ISO file is OK (I believe you downloaded it) before putting it in the USB drive. MD5 checksum is a good program to check the file's MD5 code
Also, try to format your partition and do a clean install, rather than repairing it.
Let us know!

great!!
Thanks to all for your answer. I answer to you in order:

I have a Ati Radeon Express 1250.
What do you mean for on board graphics?
I prefer try another solution first and take out the graphic card only if is very needful
I try it but I don't have any difference.
I think I have the last bios version
I burn at 4x speed with nero 9 on a dvd rw
I can use an external hard disk? I have only a 2 gb memory key.
I run the Windows 7 Upgrade Advisor (I can't save the report), it say that I have only 768 mb di ram (vista say 1 gb) and that I have 5 program that I should reinstall after I update to seven.
I check md5 and it's ok.
I already format the partition and do a clean install, but I have always the same result
Also I find this on this forum (dual boot windows 7 and vista boot error winload.execan it help you?

Milite, I am checking with SIW for the solution he had in that case.
There are a couple of problems I see though:
1G RAM is the minimum for 32 bit version, you need more for 64bit (which one are you trying?)
I have never tried with a DVD RW, but that might be a potential problem. Do you have a read only DVD you can burn?
Finally, you can unpack the ISO to the external drive and run setup.exe on that.
By the way, remoning your graphics card might be the simple solution here. Does your motherboard have on-board graphics? Do you have a VGA connector from the motherboard or only from the card?
Let us know

32 bit

And if I want to try to install from external drive, how I can launch the installation? If I unpack the iso, how I can launch the setup file from boot? I should use the tutorial posted from Dave76?

We'll talk after of the graphics card as a last hypothesis

I think you need this screen:

-cattura1.jpg

it's the right window?

c is the vista partition, f is the 7 partition, d is the dvd driver, e is a external hard disk that I open (because I have some alimentation problem) and I adapted to be a internal hard disk
