I have Windows 7 Pro on my main HD. The system is stable, runs perfectly and all programs run fine. I installed Ubuntu 10.04 release version on a secondary HD. I disconnected the Windows drive to install Ubuntu and reconnected it after installation. But since then Windows became more and more unstable. Applications like messenger and hotmail did not always start, or if they did they sometimes locked up. IE8 sometimes would not start, sometimes lock up. The pc would run slowly, lockup or not even start up. Eventually even after starting Windows it would shut down and memory checking would start. In the end it would only boot into Ubuntu and when I checked in setup the Windows HD was not recognised in the BIOS. So I gave up and disconnected the Ubuntu HD. Result is that Windows loads, runs and operates perfectly as before. I have checked most things and all appears OK.
If I disconnect the Windows drive and connect the Ubuntu drive that runs apparently OK. All programs run OK. It updates OK, and no error messages appear.
If both OS's run normally individually, is the problem more likely to be the setup of my pc's hardware rather than an OS problem. I don't need to run Linux and I am quite happy not to use it, but I was not aware that it could upset Windows quite so dramatically.

I have Windows 7 and Ubuntu 10.04 running perfect, side by side on the same drive, just different partitions.

I would think you shouldn't have disconnected the Windows drive, because when you installed Ubuntu, Grub2 would need to be able to see any other operating systems, so you would be able to dual boot.

Do not know if that was what affected your Windows tho...

It won't. Windows 7 cannot read ext4 volumes.

Yeah, I know that, but I was more leading to the fact that Grub should have written over the mbr, but with the drive disconnected, it would not be able to. And since Windows cant read ext3 or ext4 volumes, there is no way for him to dual boot.
I think he needs to reinstall Grub, with the Windows drive connected, then everything should work together as it should.

He disconnected the Windows "drive" when he installed Ubuntu. At that point it would depend on his BIOS settings to point which drive to load off of.

How he has done it is not the ideal way to dual boot.

Thank you both for that.
Do you both agree that I should have left the Windows HD connected when I installed Ubuntu?
And that I should reinstall Grub2 to sort it out?

Exactly... but then when he connected both drives, could it have confused the bios somehow, and cause the erratic behavior? (not knowing whether to look at Windows mbr or Grub)

That is why I think he needs to reinstall Grub, so it will overwrite Windows MBR.

Unless you have data on the Ubuntu install, go ahead and wipe that drive. Then install Ubuntu while the both drives are connected. Here is a good guide: http://lifehacker.com/5403100/dual+boot-wi...perfect-harmony

You can reinstall Ubuntu, or if you want to try just reinstalling Grub2, then go to this link and scroll down to Reinstalling from LiveCD.

https://help.ubuntu.com/community/Grub2#Reinstalling from LiveCD

But yes... with Windows drive attached, let Grub write to that drive where the master boot record is.

WAIT! I have an idea... before you do that, try using easyBCD first and see if it will allow you to dual boot.
It is actually a pretty amazing program.

EasyBCD

Go to the bottom of the screen for the download button.

Right thanks. I'll have a read at them all and try them out.
I'll report back as and when.
