I have installed Ubuntu 12.04 (32 bit) on a laptop with Windows 7 (32 bit): the bootloader is the GRUB version provided with Ubuntu 12.04. Now I would also install Ubuntu 10.04 (64 bit), without overwriting the bootloader installed with Ubuntu 12.04. Obviously I would like the GRUB previously installed by Ubuntu 12.04 can boot all operating systems installed (Windows 7, Ubuntu 10.04 and Ubuntu 12.04).
- Could the bootloader installed by Ubuntu 12.04 (32 bit) start also Ubuntu 10.04 (64 bit)?
- If I install Ubuntu 10.04 unchecking the option to install GRUB, the previous version of GRUB should not GRUB would not be configured to start Ubuntu 10.04.
- What is the correct way to proceed?
