I have a problem with an HP server. Occurred the following ProLiant server had problems and was on the motherboard replaced. The HP technician does not reset the BIOS to use the RAID configuration of which was the installation of Windows Server 2008 R2. The same technician tried to recover windows which of course did not work because the drivers from the hardware store have changed. With Windows DVD b able to boot and install the drivers for the pen-drive RAID unable to access the RAID partitions initially managed to make a boot server, after using the chckdsk to correct some errors. But when you restart the server it can no longer start. The initial installation was done using the DVD from HP and was not created a boot partition (100 MB). When I use diskpart in order to repair the Windows DVD appears the Windows partition as active. Can anyone help me what to do to solve this problem.

Hi, Please try to perform a restore if you have any backup. By the way, it is recommended that you contact HP to perform the further research. Best Regards, Vincent Hu

I don't have any restore. The server are new, with litle time of use. HP Brazil reports that support is only the hardware or seek the technical should make the switch to the motherboard, or is that I'll have to solve the problem. I know there must be a way to rebuild the boot server, just do not know how to do it in Windows Server 2008, I have done this in XP Professional eg. Thanks
