Preparing a Boot Environment That Supports the Installation of Multiple Operating Systems
If you are installing Oracle Solaris as part of a multiple boot
environment, review the specifications for the various operating systems in the following table.
Table 2-1 Multiple Operating System Environments
If you have Windows installed, and you set up sufficient disk
space for installing Oracle Solaris, the installation should be straightforward. All versions of Oracle
Solaris for the x86 platform use the GNU Grand Unified Bootloader (GRUB). Oracle
Solaris recognizes Windows and ensures that Windows partitions remain unchanged during an installation.
When the installation completes, and the system reboots, the GRUB menu displays both
the Windows and the Oracle Solaris boot entries.
Linux, or Windows and Linux
have the Linux operating system, or both Linux and Windows operating systems installed
on your x86 based system, before installing Oracle Solaris, save a copy of
file. After the installation, you will need to edit the menu.lst
file to add the Linux information from the previous installation. For instructions, see
How to Add a Linux Entry to the GRUB Menu After Installing Oracle Solaris
Note - When installing Oracle Solaris on a system that also has the Linux operating
system installed, the Oracle Solaris partition must precede the Linux swap partition.
Solaris 10 OS
The installer on the live CD and the text installer
cannot be used to boot multiple instances of Oracle Solaris. However, the installers
can be used to replace the Solaris 10 1/06 and later releases on
an existing system that has multiple instances of Oracle Solaris installed.
Note - If you need
to preserve a specific Solaris Volume Table of Contents (VTOC) slice in your
current operating system, use the text installer.
If you have another operating
system on an extended partition, the existing extended partition does not need to
be changed during an installation. You can create, resize, or delete an extended
partition when you install Oracle Solaris by using either the live CD GUI
installer, the text installer, or the automated installer. You can also choose to
install Oracle Solaris on a logical partition within an extended partition.
