Dual-booting all versions of Windows and Linux
Install Dual-Boot of Linux Ubuntu 9.04 or 8 on a Windows Vista computer (Vista installed first and GRUB controlling startup after Linux installation)
Last reviewed: June 2009
This guide shows how to correctly and safely create a natural dual-boot of Windows Vista and Linux Ubuntu 9.04 or 8.x on a computer with Windows Vista already installed. Linux's boot loader, GRUB, will be in control after the Linux installation. You can then run either by selecting that OS from a menu during bootup. If you already have a Windows-controlled dual or multi-boot, they will be retained and will be accessed from a sub-menu when Windows Vista is selected. No data loss will occur and a third-party boot utility is not used.
In this procedure you need to shrink the Windows Vista drive to make room for Linux.
32 and 64-bit versions of Windows Vista were used in testing The operating system added was Linux Ubuntu 9.04 or 8.04. The computers used were (1) a 32-bit Dell Optiplex with Pentium 4 (2.26GHz), 2.0 GB RAM, 160 GB ATA hard disk, and (2) AMD Athlon 64-bit (2.4GHz), 2.0 GB RAM, 1 TB SATA hard disk.
