VM machine corrupted ntldr - cannot boot

Hi all,

I got a VMware esx3i the free version which is without support.

Anyway we had a power outage in our office and we use a microsof domain AD and the our ESX Server went down. We now use UPS so we are OK for the future.

Unfortunately one of the VM machine which is a netbackup server (Windows Server 2003) doesn't boot anymore we get "ntldr corrupt cannot boot".

I do not want to install the netbackup server from scratch as we had important configuration settings and the vtl software installed.

I do not know how to get this solved. I am not really a top microsoft guy and also this is a VM machine.

There is anyway that we can repair ntldr? If yes how shall I do so? Could anyone instruct me?

    You can use your Windows CD or iso to boot the VM and perform an in placd repair and install.  It will not harm your data and will fix the ntldr.

    you should really consider a backup plan for that server. Call it malware or wrong patch, you must backup such an important server.

    You should not repair.  Run a chkdsk /r using the recovery console, this resolved this issue 9 out of 10 times on physical and virtual servers
