          Dear 850438 ,

          1) enter rescue mode and delete the MBR on the disks as below.
          # dd if=/dev/zero of=/dev/sda bs=512 count=1

          2) Reinstall the system again.

          It should work

          Please, mark the question as answered and the post as Correct if it solves your issue. Otherwise, as helpful.

          Best Regards

            Your server uses UEFI-compliant server firmware that supports UEFI and standard BIOS and should detect the correct mode. However, it favors UEFI over BIOS. http://www-947.ibm.com/support/entry/portal/docdisplay?brand=5000008&lndocid=MIGR-5083207

            Keep in mind, that any disk that is larger than 2 TB requries the GPT partitioning scheme. The GRUB bootloader of Oracle Enterprise Linux 5.5 does not support GPT or EFI. I suggest to check the product documenation and installation notes specific for your system.
