You've been hit by the Dell configuration of Windows on their hardware, I suspect. This was noted a couple of years back when people couldn't install Debian on Dell laptops. The answer is probably to switch it - to obtain the recovery media you need to reinstall Windows / just download the .iso, switch it to AHCI and install Windows like that. I think it's _just_ a Dell funny. Andy - who's just done somthing almost identical to a second hand Thinkpad - putting it back to manufacturer's original installation media to ensure that I could install it my way. (And you've reminded me that I probably need to write a blog post on how to get Debian and Windows dual booting nicely with Bitlocker on Windows) All the very best, as ever, Andy Cater >
