Server 2008 R2 - crashed. restarting itself.

Server 2008 R2. keeps rebooting while trying to load windows.
When i start the server, it says, starting windows and restarting itself

i checked the raid in raid storage manager. it looks good. status is bootable.  and from bios, i can see the harddisk as the first priority to boot.  so i dont think it is an hardware issue. i did memory diagnostic test. no issues found. further, i tried to boot from single harddisk - still same issue. and when i plugged back the second harddisk, raid went to rebuild ? is does not mean i will lose data , right ?

think its something to do with software side. tried to boot from safe mode, same issues. keeps rebooting. dont have a previous versions to restore.
i never did repaired a server. any ideas to do repair or to work around this issue.  ?

Can you boot from the Server 2008 CD?  And then if so, can you do a Repair Install?

Be sure to have a backup first.

try using Paragon Kit Free or Lazesoft Recovery Suite Home Edition to check and repair

Which RAID configuration?
I would think it got corrupt, can you try booting from a CD and see if the HDD is accessible?
Mr.XAuthor Commented:
Raid 1. 2 Disks
Can I use any 2008R2 CD, or could I use only the CD which came along with server(which I don't have ) ?
Mr.XAuthor Commented:
In BIOS, I went system logs . I found 2 error messages like.

EFI 030D0006 major
Not sure what they are
JohnBusiness Consultant (Owner)Commented:
You can use the CD that came with the server.

I cannot interpret the BIOS logs. From what I saw, they are informational messages.
Mr.XAuthor Commented:
I don't have the CD which came with server.
Can I use any 2008R2 CD, will it work. ?
JohnBusiness Consultant (Owner)Commented:
You can try, but I am not certain when you go to repair
Mr.XAuthor Commented:
Ok thanks. Will give it a try
Mr.XAuthor Commented:
I have never done a repair on server with CD.
Do u know any videos or manuals on how to do, any steps for me to refer ?
JohnBusiness Consultant (Owner)Commented:
It should be a button / icon when you start. If not, then the CD does not offer the repair option.

Hi Mr.X
From what you’re telling me it seems like your MBR(Master Boot Record) has been damaged from a virus attack or bad sector in one of the hard drives in your array.
To repair your MBR firstly you’ll have to partition the System Reserved Partition which is already reserved (100 mb), please follow these steps:
1.      Insert your Windows Server 2008 R2 Server DVD and then press Shift+F10 and this shall open up Command Prompt
2.      Type in Diskpart
3.      Type in List Vol
4.      Note down the drive letter of your Windows DVD Drive.(We’re assuming its is f: )
5.      Type Select Vol 1( assuming volume 1 is the system reserved volume)
6.      Type Active
7.      Then type Copy f:\BootMgr c:\  , Now 2 cases will occur
i.      If Bootmgr already exists on C: Press N and don’t overwrite it
ii.      If it doesn’t exist then the Bootmgr will automatically be copied to the reserved partition
8.      Type Bootrec /Fixmbr, press enter,
9.      Type Bootrec /Fixboot, press enter,
10.      Type Bootrec /rebuildBCD
11.      If BootRec /RebuildBCD is successful, it will list any installations of Windows that it found. Press Y to agree and append them to the BCD.
Note: If no OS is found then you will get Total Identified Windows Installations: 0 , if this occurs one of the following is true
i.      The OS is not there.
ii.      The OS is damaged beyond the ability of BootRec to recognize it.

Hope this solves your issue and you get your data back intact .
