The following procedure describes how to install the Oracle Linux operating system from local or remote media. The procedure assumes that you are booting the Oracle Linux installation media from one of the following sources:
Oracle Linux 6.x ISO DVD image (network repository)
Note - If you are booting the installation media from a PXE environment, refer to Install Oracle Linux 5.x or 6.x Using PXE Network Boot for instructions.
For additional information about how to set up the installation media, see Selecting the Boot Media Option.
The BIOS screen appears.
Note - The next events occur very quickly; therefore, focused attention is needed for the following steps. Watch carefully for these messages as they appear on the screen for a brief time. You might want to enlarge the size of your screen to eliminate scroll bars.
The Please Select Boot Device menu appears. The screen that appears will be different depending on whether you have BIOS configured for legacy BIOS mode or UEFI mode.
For legacy BIOS, the following screen appears:
For UEFI BIOS, the following screen appears:
Note - The boot device menu that appears in your installation might differ depending on the type of disk controller installed in your server.
For legacy BIOS, the Oracle Linux 6.x Welcome screen appears.
For UEFI BIOS, the Oracle Linux 6.1 GNU GRUB screen appears.
Note - For Oracle Linux 6.2 and 6.3 the screens are similar.
To install from the legacy BIOS mode, select Install or Upgrade an Existing System from the Oracle Linux 6.x Welcome screen, click Next at the bottom of the screen, and follow the on-screen prompts to complete the interactive installation.
To install the Linux operating system in UEFI BIOS mode, select Oracle Linux Server 6.x from the GNU GRUB screen and press Enter.
The Choose a Language screen appears.
The Keyboard Type screen appears.
The Installation Method screen appears.
The Disc Found screen appears.
The Oracle Linux 6 splash screen appears.
If there is a problem with the data format on any target disk, the Partitioning Error warning appears.
If this is the storage drive that you want to use for the installation, you need to reformat the drive; otherwise, you can ignore this warning.
To reformat the disk, click Yes.
Otherwise, the Installation Devices screen appears.
The Examining Devices screen appears.
If the above screens appears, the disk to which you are attempting to install the Linux OS is formatted incorrectly and it needs to be reformatted.
Note - This error occurs if you attempt to do a UEFI BIOS OS install to a storage drive that was previously used to store data in legacy BIOS format or vice versa. UEFI uses the GUID Partition Table (GPT) format, while legacy BIOS formats storage drives in the Master Boot Record (MBR) format. The storage drives that ship with the server are new, so they are unformatted. You will not encounter this error when installing to an unformatted disk.
To recover and reformat the disk without aborting the install, click the keyboard Back button several times to return to the initial splash screen shown in Step 9 and perform these steps:
The shell appears.

Otherwise, the Bootloader screen appears.
The Select Software screen appears.
The Starting the Installation Process screen appears.
You have completed the installation user interactions.
The BIOS screen appears.
For legacy BIOS, the following BIOS Setup Utility appears.
For UEFI BIOS, the following BIOS Setup Utility appears.
For legacy BIOS:
Select Boot in the top menu bar and verify the target installation storage drive is at the top of the list under the Boot Option Priority field.
If the target installation storage drive is not at the top of the list, move it to the top and press F10 to save the change and exit the BIOS Setup Utility.
For UEFI BIOS:
Select Boot in the top menu bar and verify the Oracle Linux Server is at the top of the list under the Boot Option Priorities field.
If Oracle Linux Server is not at the top of the list, move it to the top and press F10 to save the change and exit the BIOS Setup Utility.
If you do not want to change the default Kernel, proceed to Step 22.
The GNU GRUB screen appears.
Note - The above GRUB screen lists the default kernel for Oracle Linux 6.1. The GRUB screen for Oracle Linux 6.2 lists the default kernel as 220.127.116.110.3.1.el6uek.x86_64. The GRUB screen for Oracle Linux 6.3 lists default kernel as 18.104.22.168.24.1.el6uek.x86_64, which is the Oracle Unbreakable Enterprise Kernel Release 2 for Linux.
