A few weeks ago on 5 May Microsoft released the release candidate of Windows 7. It’s a free download, so I decided to give it a try. Unfortunately Windows 7, just like the older versions, will brutally overwrite the master boot record (MBR) without asking. This meant I had to restore the GRUB bootloader to the MBR to be able to start Ubuntu again. Fortunately there are very easy instructions available on how that should be done. I’ll write my thoughts about Windows 7 at a later time.
