I have inherited a new server that someone else installed Windows Server 2008R2 onto, it contains 3x3TB disks in RAID 5 and was installed using MBR, there is a 3.5TB partition that I am unable to use because the server was not installed using UEFI BIOS and GTP disk.
1. I assume I have to reinstall the OS on this server using UEFI BIOS and selecting GTP disk to utilize all the space, is this correct?
2. Is it possible to do an image backup of the existing install, reinstall the OS, change to UEFI BIOS/GTP disk and then restore the image backup? Would this work?
3. Are there any other options available to me other then reinstalling, or using alternative methods to restore the existing install?
The server is a Dell Power Edge T320 with a dell hardware raid controller, the disks are 3TB SATA.
Thanks
AM
