Ubuntu :: Can't Boot Windows Anymore Because Of 'keys'?

I need to use bluetooth, but for some yet unknown reason I don't seem to be able to switch on the bluetooth-card (it should be as simple as to press the Fn+F6 buttons on the keyboard to switch it on though and then the bluetooth indicator should light up, which is not happening, but I don't know if this is because of (X)ubuntu) and Ubuntu says it can't find the bluetooth card. That's not what I wanted to discuss now, but I think some history is always welcome when trying to do fault-finding I thought I maybe might be able to do it from Win7 . So after months of not having booted Win7 I thought to give it a try, but I get stuck right after the grub boot-screen. All I get is a blinking cursor for minutes and there's no HD activity. Then I booted Xubuntu again and it needed to do some check, which I passed and Xubuntu started as normal. This check was done by "Keys". I don't really know what this Keys is, but since a couple of days I always get this word below the word Xubuntu in the boot-splash-screen. This is only after I installed WinFF or DVD::RIP. There was some error during install telling me that it needed something with 'keys', so I entered the command quoted, something was installed and then the rest of the installation went okay. I've been looking in the bash_history files (user and root) but I can't find the command which I entered to install this keys-thing anymore, which is of course strange on itself.

Now I've got the idea (I'm not sure though) that I can't boot Windows because of this keys thing, but I have no clue how to get rid of it. Or could there be other problems causing Windows not to boot?

I really hope someone can help me getting back in Windows again, because losing the Windows partition really is not fun, even though I hardly use it. I can enter the Windows partition from Linux with a file manager though, so it's not vanished. Just wish to be able to boot Win7 when I need it.
