Trying to allocate 1005 pages for VMLINUZ error when booting with RHEL or CentOS 6.5 disks

 

I was booting the RHEL 6.5 or CentOS 6.5 on a IBM PureFlex System and I have this error. This occurs when When installing Red Hat Enterprise Linux 6 from DVD media the installation will default to native Extensible Firmware Interface (EFI) mode boot. I do not have

According to IBM Website, 

The workaround is simply to install the operating system in the traditional legacy mode, since there is generally no reason to install in other than Legacy mode. The workaround is only necessary if the media you are booting defaults to EFI mode (DVD or EFI Preboot eXecution Environment (PXE)) otherwise a legacy installation (e.g. - traditional PXE) is the default and is unaffected by this issue.

To force a legacy installation of the operating system from the EFI bootable DVD media the user should:

    Press F12 key when the IBM splash screen is shown during system boot.
    Select Legacy Only option and press Enter.
    The operating system will boot and install in traditional legacy boot mode.

And the issue was resolved.
