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 set 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 and other information from the hardware store have changed. The server now stay on black screen during boot without any message, only in log of Bios is displayed a message about unknow O.S.

The initial installation was done using the DVD from HP and was not created a boot partition (100 MB).

Using the Windows Server 2008 DVD to boot and installing the drivers for RAID from pen-drive I can see all windows partitions on RAID, but repair options fail to repair boot. I don't have any restoration point to try restore this server. When I use diskpart in order to repair the Windows DVD appears the Windows partition and the partition with windows instalation is active but don't Boot.

HP Brazil reports that support is only the hardware and I need seek the technical has should make the switch to the motherboard for solve the problem, 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.

Can anyone help me what to do to solve this problem.

Thanks for any help.

Can you get to a command prompt either from the repair DVD or F8? If so try one of the following:

bootrec /fixmbr (press enter)
bootrec /fixboot (press enter)
bootrec /rebuildbcd (press enter)

or try this

del c:\boot\ /f /s (press enter)
bootrec /fixmbr (press enter)
bootrec /rebuildbcd (press enter)

/fixmbr its ok
/fixboot display object missing
/rebuildBCD the same message "object missing". This command locate windows instalation.

I try bootsect /nt60 all /force but don't work to.

How am I doing boot from the DVD and have to use the RAID driver to a flash drive drive letters change on each boot and the OS drive (C:) is usually charged with the letter F or G

In windows partition I have a bootsect.bak bootmgr and bootmgr.efi files/folders only. Don't have any boot folder

Problem solved finally.

After trying various solutions found on the internet microsoft page (technet) command savior.

My savior was BCDBOOT command.

BCDboot C:\Windows /s C: /v

Only this and my Server 2008 R2 boots again, and now working without problems.

Thanks for help.
