nForce video drivers keep disapearing after each restart

By roise4000 ·
i have (had) a dual-OS machine (vista & XP) and accidentally deleted the boot directory on the boot partition. unfortunately i dont have the Vista cd at the moment so i figured i should fix at least my XP OS using its CD, /fixboot and /bootcfg... and i did, everything was fine until the graphic interface loaded, where my resolution was lowered. i checked the display settings and noticed that my display drivers are no more. so i scratched my head for a moment and thought no biggie, just reinstall the drivers. so i did and everything was fine and i was able to work with my normal resolution for a while. after restarting for some reason... the same story, no more display drivers. every time i would install them, everything works fine until the next restart ...? ????/

pls help ...

Only thing I can think of here

by OH Smeg In reply to nForce video drivers keep ...

Is that owning to the way that this was setup the NVidia Drivers are not being copied tot he XP Partition but the Boot Partition for the Other OS.

Then because of a corrupt Boot Loader when you restart the system the Driver files are not being accessed. When it is running nd you load the drivers the system is loading them Virtually and quite naturally when you reboot the unit these disappear.

You need to fix the unit up properly here to stop this from happening. So you'll need to find the Vista Install Disc to do this.

If XP was the first Operating System installed you can try this

by Jacky Howe In reply to nForce video drivers keep ...

Use Bootsect.exe to restore the Ntldr program.

Boot from the XP CD and at a command prompt.

Now type in bootsect.exe /nt52 C:

fixmbr and press Enter

fixboot and press Enter

bootcfg /rebuild and press Enter

Wait until you are returned to the Recovery Console.

Once you are back to the Recovery Console remove the XP CD and restart your PC.

i dont think there is something wrong with my master boot .?. i had bad experiences doing that from the past, i had to delete the whole drive and use a recovery soft to retrieve my data after doing that . i prefer reinstalling XP than using fixmbr. but yet i dont want to reinstall XP

P.S. how come the forum is not notifying me through email at new posts?

So this is a fresh install

by Jacky Howe In reply to what will it do ?

after you removed Vista or did you just delete or format the Vista Partition. Using the information that I previously provided will recover the boot environment prior to installing Vista. It's up to you what you choose to do as I'm only suggesting what I would do.

how come the forum is not notifying me through email at new posts?

The site has been going through some changes recently and not everything is working as expected. Check in Manage My Account and make sure that I wish to be notified on information and offers from TechRepublic's partners via postal mail is ticked.

When you find your Vista DVD

by Jacky Howe In reply to i still have both OSes

do a Startup Repair that may solve your problems.

I take this is what you are asking about here

SOLUTION: Win XP won't keep video driver upon reboot VIA KM800

I found a solution which did not require reinstalling sp3: replace just the SYSTEM registry hive. I booted a Linux recovery CD, mounted the HD, and moved windows\repair\system to windows\system32\config\system, rebooted, reinstalled drivers, and all is good now!


Here the Hive file is the Default after Installing Windows your current file which is bigger will have modifications from every Patch Service Pack and what not that has been installed since Windows was originally installed.

Now while this should be perfectly OK to use there may be some small issues down the track with references missing to some things but these should be minor.

Here because of the Dual Boot Option that is in use I think you'll find that you corrupted something when the Vista Partition got whatever it was done to it and this is what is causing your current problems.

Windows always writes files tot he Root of the Master Boot Partition which is straight Hardware Related not Software Related to start. In the old days you had to install Windows on the Primary Hardware Boot Partition to be able to use it but it has been developed since those days to allow you not to install it on the Primary Hardware Partition. This can cause some problems with people who fail to understand how this system works and think that because the software sees something one way the computer is that way.

Unfortunately Computers are not Intelligent, Marvelous or Magical they are really very dumb and when you attempt to use them beyond their limits you have problems. Here you really need to repair the First Installed OS on this computer before this will work correctly.

To do that you need to do a Repair or In Place Install of the Primary Installed OS first and then finish off with the Second OS. Here are the directions for doing this with XP but you need a M$ Branded Install Disc not a System Makers Recovery Disc to do this.

But regardless of what this says you should always have a Solid Working Backup before proceeding any further.

the real problem just revealed it self

by roise4000 In reply to nForce video drivers keep ...

i dont know why i had the bad feeling this would happen.

i will try to be as clear as possible, although maybe this is for another thread:

i found my vista dvd, i booted from it, i went into "repair my computer". as soon as i hit that, the installation started doing something and came back with a message of the sort: "windows found some problems with your start-up. do u want them fixed" i said "hm, that was easy" and said "repair and restart" or something. it did and when it was about time to let me choose between XP or Vista, XP just started loading very graciously :), no vista whatsoever !!! i restarted, loaded again the vista dvd, hit the "repair computer" button again and this time the installation did not do any automatic checking but instead gave me a bunch of options like "restore your computer from backup, restore to a previous point" and at the top: "automatic start-up fixer" or something. so i click that. it said "searching for windows versions", a window came up *showing the correct vista OS as the only option*, and in parenthesis: (recovered). so i click that, hit next. it did some more checking and came with the message: "if u have any iPods or externals whatever plugged, disconect them now and restart this process. if this message keeps appearing, contact the admins" i dont have any iPods or other of the sort. if i click on "details" on the same screen, i can read some messages stating "OS loaded successfully", but i cant understand is it talking about now, or the last successful load. I am stuck! Should I PANIC NOW! :)
i think that the vista installation did what it was supposed to do regarding to fixing the booting of the vista OS, but the XP loader is preventing vista even to show up as an option. XP loader runs fine, vista loader - no trace
