Vista - Vista replaces MBR - is there an option to disable this???

Hi,

I've written a boot manager (www.sadevelopment.com) that allows you to boot
up to 256 operating systems with logon security. It uses a custom MBR to
launch itself, but when this customer boots Vista, Vista replaces the MBR.
I only have this with one customer. I've installed Vista myself as numerous
other customers have with no issue.

Way back when the Vista beta was out I saw this behavior. I have to think
there is some option or setting in Vista that was enabled during the beta
that did it and that this customer must have that option enabled somehow.
He says it is not running beta, but he says it has SP1. Does anyone know of
an option or registry setting like this?

Thanks,

Alan

how about using vistabootpro to see what the bootmanager is up to?

you can even uninstall and reinstall the vista bootmanager

VistBootPro is a ripoff of the actual original program called EasyBCD by Neosmart Technologies. Download EasyBCD 1.7.2 - NeoSmart Technologies

When installing multiple OSs or simply different versions of Windows each should already be installed since each installer will see it's own new entries placed in the boot drive's mbr replacing others. Any 3rd party boot loader is the last thing to be installed.

Hi Night Hawk,
My product keeps each OS in its own SEPERATE partition, so they don't mix
and are hidden from each other, and they are installed normally.

I am still looking for an answer to my original question.

Thanks,

Alan

Hi,

So no one knows of a ini option or registry setting that enables/disables
this??

Thanks,

Hi Rick,

I'm still trying to figure this out.

Customer is running x64 version with the newer style boot mechanism
(bootmgr, bcd).

I did a fresh install of vista sp1 x64 and it does not do what the customer
version does. It replaced the MBR one time during setup, but once my boot
manager reactivated itself (putting its mbr back in), vista does not replace
the mbr again.

The customers pc is different, each time he boots vista, it replaces it.

I will have him report the attributes he has from diskpart...

Thanks,

Alan

Hi Rick,

Here it is:

The first 8mb partition is where my boot manager resides. The third
partition may represent more partitions that are hidden from the WVista.

WVista (C is the problem child, when booted it will always replace the MBR
everytime...

Thanks,

Alan

Hi Rick,

A good thought, but it only happens when he boots vista. He has another OS
installed and can boot it and it doesn't replace the MBR.

I saw behavior like this back when Vista was in beta, the beta versions
would do it, but the issues all cleared up for the release version...

Thanks,

Alan
