Basic Disk Convert to GPT Disk not active
Hi,
I have one Dell PE2950 Server, I installed Windows Server 2008 Standard with SP2
Upgrade the BIOS, Raid Firmware PERC-6/i, ESM Firmware, NIC Firmware
Install Server Administrator 7.0
I have four 2TB HDDs with Raid-5, made C:\100-GB & remaining for backup
I am able to create just one partition 2TB and remaining not able to use
Even I tried to convert Basic Disk to GPT Disk this option is also not working as mention below pic
Now I am looking forward for your response may be you have some solution for this problem
I want to use this server for ERP Backup so I need big Partition for full & daily backup so plzzzzzzzzzz.........
I installed windows 2 time but result is same.
With Best Regards & Thanks

Windows can only see disks larger than 2TB IF it is a GPT disk, HOWEVER ... Windows cannot BOOT to a GPT disk, UNLESS ... you install a 64-bit version onto a GPT disk on a UEFI-enabled system.
The catch? The PowerEdge 2950 does NOT support UEFI.
The workaround? You can do one of two things:
1. Create two 2TB RAID 1's. Both RAID 1's will be small enough for Windows to work with without any problems.
2. Create two Virtual Disks (arrays) across your four disks - VD0 will be 100GB, and VD1 will use the remaining space. You will do this in the CTRL-R utility during POST. First, delete the existing VD. Second, configure a new VD; specify the size as 100GB, checking the Advanced and Initialize boxes. After creating your 100GB RAID 5 (VD0), then install Windows to that. After Windows is installed, then create a second RAID 5 VD (can be done from OMSA in Windows). Once you have configured and initialized this VD, then convert that disk (Windows will see each VD as a separate "disk") to GPT.
