3. Windows 7 Installation Using Avago Controllers
The first step to installing the Windows 7 operating system is to decide if a traditional MBR partition is suitable,
or if a GPT partition would be required based on the system configuration. Bootable MBR partitions are limited
to a maximum size of 2TB, while bootable GPT partitions are capable of supporting much larger sizes (the limit
varies based on the operating system used). Some BIOS changes might be necessary in order to boot the
desired partition type. Legacy BIOS is capable of booting MBR or GPT partitions as long as they are no larger
than 2TB. UEFI BIOS is capable of booting only GPT partitions, but is generally not affected by any size limits.
Note Users will need to successfully set up any drives attached to the Avago controller prior to installing the
OS. This includes single drives and any drives to be included as part of a RAID. For single drives, users must
ensure the drive is set up in a single drive RAID 0 mode, or in JBOD mode. See the “How to Create and Configure
RAID Arrays” whitepaper for detailed instructions on this procedure.
The steps below detail how users should set up their BIOS based on the desired boot partition type (MBR or
GPT).
