it sounds like the disk was initialized as mbr (http://blogs.technet.com/b/josebda/archive/2009/02/07/can-you-convert-an-mbr-disk-to-gpt.aspx). as this is your boot disk, it depends on your os if booting from a gpt disk is supported (http://msdn.microsoft.com/en-us/windows/hardware/gg463525) as well as on your bios (UEFI capable?) the build in tools can only convert with data lose (deleting the partitions), not sure what other tools are out there that might convert loseless

depending on the budget, one option you have is to buy a smaller disk for the os (say 250gb, using mbr) and use the 8tb drive as data volume (when not booting from it, you dont need uefi bios, the current windows versions support gpt drives as normal volumes)
