I have Ubuntu 11.04 installed on my machine and I would like to install windows 7 as well. I heard that Windows 7 creates an additional partition along with the normal one and I was afraid that this might overwrite some of my ext3 partitions.
To avoid this risk I'm thinking of installing Windows 7 on a separate drive. Will Windows affect the MBR if they are installed on a separate drive? Do I have to edit grub after installing Windows? Is there any safe/easy method to do so?
