I would like to install Ubuntu on my computer. I currently have Windows 7 and I have the boot (recovery) CD I made with Acronis True Image 2011. I know that GRUB re-writes the boot loader so is this going to affect the Acronis Recovery Manager? If it will, what do I need to do to prevent the Recovery Manager from being usurped by GRUB? Or, will Acronis Recovery Manager only execute AFTER I execute Windows 7 from GRUB?
