Problems installing Windows on GPT disks

Computers with Extensible Firmware Interface (EFI) using GUID Partition Table (GPT) than the standard hard drive partitioning system. Intel is proposing it as a replacement for the PC's BIOS, the master boot record (MBR). Uses in GPT-partitioned disks, data, the platform for Europe is important, in partitions and not in hidden or unpartitioned sectors, as done in MBR partitioned disks.

Through these and other similar factors, issues to watch you sometimes, an especially during the installationWindows operating system. To solve such problems, you need to delete all disk partitions and for suitable partitioning scheme. This erases all data and information as to restore, you must complete with your current backup and can restore valid data. However, if the data is not updated, is corrupted or missing, you can scan the data recovery applications, and recover your data.

As a practical example, if you try to install Windows Server 2003an x64-based version of Windows Server 2003 or Windows XP, you will receive the following error message:

"Setup can not install the selected partition. You can only access disks on IA-64 machines and MBR disks on X-86 machines GPT. You can only upgrade installations on GPT disks on IA-64 machines and MBR Hard to X-86 machines. To return to the previous screen press. "

CAUSE

This error occurs when these two conditions are met:

An operating system is alreadyInstallation on the hard disk, or it was an operating system that has been removed.
The drive is GPT formatted

It does not require operating system on GPT disks because of the following reasons for the installation:

On GPT disks, you can only set up Windows Server 2003 systems, the Itanium-based systems.

You can not set up Windows x64 and Windows 32-bit operating systems based on GPT disks.

Solution

You need to convert a GPT disk to an MBR diskdrive. You can not use Disk Management or Diskpart, when an OS is already installed. You can also delete all existing disk partitions while running Setup program and convert for the possibility of partitioning scheme. In Windows Server 2003-based systems, you must have installed Windows Server 2003 Service Pack 1. Then you can lost data from the backup. If backup has been produced error or not taken, you can Hard Drive RecoveryApplications.
