Error message during the installation of Windows 2008

[banque_fr]

I try to install Windows Server 2008,
on an HP ProLiant DL585 G6
 
But FRONT WINDOW instalation of Windows the message look like:
 
"The selected disk is of the GPT partition style" So can not install Windows 2008.

I tried to partition, format, but it changes nothing.

The disc (4) are managed by HP Smart Array P400 controller in raid 5/6.
 
I hope to find a solution.
Thank you for any insight.
Cordially.

HI:

GPT is supported by Windows Server 2008 X64 or Windows Server 2008 R2 on UEFI based systems,so you will use of a 64 bit Windows 2008 DVD,but ProLiant BIOS are not EFI/UEFI complaint,so you could create a logical drive that less than 2TB  in the disk array that you will install Windows 2008(For the GPT 2TB Disk Limit).After you have installed the OS,you can convert the other free disk to GPT Disk in Windows Disk Management.

BTW,you can also convert GPT Partiton to MBR Partition in CMD at the start of you Windows 2008 X86 installation screen.Be sure you have a good backup of all your data!

Press Shift + F10 here,and cmd.exe will show up

Then type "Diskpart","list disk","select disk X"(X stands for your local disk you want to convert),"convert mbr"

After that,you can try to install a 32bit Windows Server 2008.

Good luck!
