Why the windows 2008 r2 boot disk cannot detect the virtual disk?

My new IBM x3650 M4 server was brought in for windows 2008 r2 setup. I have created a RAID 5 virtual disk, 4.65 TB in size. Now, I power up the server and chose to boot up with my Windows 2008 R2 boot disk. Everything went correctly, until choosing the disk to install, and to my surprise, no disk is present. But, if bootup using my 2012 boot disk, the virtual disk - 4.65 Tb can be detected, why?

I saw this time stamp for my w2k8 r2 is dated 2009.

Thats because Server 2008 R2 only supports a 2TB MBR

At the end, I managed to the server setup with w2k8, by using IBM ServerGUIDE cd. As in accordance to IBM, server setup is best to be done with ServerGUIDE.
