4.2.5 Starting the installation Before you begin, make sure: You have created a mirror volume for Windows installation. We recommend you install the operating system on a RAID-1 mirror rather than a single disk. See "Configuring SCSI controller and internal disks" on page 74. You use a GPT disk for the installation. If you are about to install Windows on a disk previously used by an IA-32 system (with a MBR disk structure), follow the procedure discussed in "Deleting the disk content" on page 78. Tip: If the disk you install to is still an MBR disk, the installation procedure will prompt you and will convert the disk to a GPT structure. There are two ways to start the operating system installation: automatically or manually. Booting the installation CD automatically From the Boot Manager menu, select the CD-ROM in the list (as shown in Figure 4-11) and press Enter.
