also for other disk???? that disk is just a data disk. But you could be right ... I don't hope so. A friend of mine has to disks, 1 with linux and one with win7 and uses bios as bootdisk selecter. When he does a startup repair from win7 f8 or repairdisk .... would it repair the mbr on linux disk as well?

Don't hope so

it often still gives a yellow nvstor exclamation mark error. This the system recovers from but the red error it hangs on
you mean yellow exclamation mark in device manager? what do you mean by red error?
errors in eventviewer?

A data HD can indeed block booting with a corrupt MBR but I've not seen it change boot order.

The issue seems to be settled by setting the correct HD to boot first. If it switches order again I'd try the line Command given or move the data off the data drive to wipe it's boot sector using Diskpart Clean Command.

It seems like an Nvidia storage controller is causing issues. Was this driver issued by the installer or optional Windows Updates or did you incorrectly import it from the manufacturer's chipset without performance issues causing the need for this?

What I'd want to do first is roll back to the installer's storage driver if necessary, or update the driver if this is it's only version. Check optional Windows Updates first as Win7 is the authority on its own drivers.

Also I'd turn off all Nvidia services in services.msc as they are unneeded bloatware unless you use special controls included in their settings. Win7 has better versions of most of these controls anyway. Services - Start or Disable - Windows 7 Forums
