I have installed Linux (Ubuntu 'Dapper Drake') on a slave drive which is working well.
I have WinXP Pro SP2 on my master drive and the auto-installed Linux grub gives me the option of which to load at boot (default-Linux).
Both O/S's were working well together and I had rebooted succesfully around 20 or so times, switching between O/S's over the last 36+ hours since I originally succesfully installed Linux.
However, I have just attempted to load WinXP and an error message popped up entitled 'Windows Product Activation' saying: "Some files are missing or damaged. You cannot log on at this time. Please use your installation CD to reinstall or repair Windows. Error Code:0x80040507"
Now, I've done as instructed and booted the PC using my original WinXP installation disc. I've launched the recovery console and have logged into Windows (dos screen) as Administrator.
However, I'm unsure of what steps to take next as there are no options available.
Any advice / help greatly appreciated.
