If the boot loader to your Windows Server 2008 machine gets corrupted or deleted for whatever reason, it really is a painstaking process to get it fixed. The boot loader to my machine got deleted somehow while I was resizing partitions. After scouring the web, I could not find anything on rebuilding the boot loader for Windows Server 2008. All I could find were instructions to restore a Windows Vista boot loader but luckily, the process for Server 2008 is similar.
Due to the lack of recovery tools on the Server 2008 installation CD, the boot loader must be rebuilt manually.
For this guide, I’m going to assume your installation has a drive letter of C:.
Insert the Server 2008 installation CD into your DVD-ROM. Restart your computer and boot from the CD.
Choose to repair your computer, then open the command prompt.
At the command prompt, use the following commands:
bootsect /nt60 c: /force /mbr
After using the “bootrec /rebuldbcd” command, you will be prompted to accept a Windows installation. Accept the installation, then wait for the process to finish. Once it’s done, reboot your comptuer and you should have a boot loader ready to go.
If you do not have a “boot” folder in the system C: drive, then copy the “boot” folder form the Windows installation CD to the C: drive. Use the following command which assumes E: is your DVD-ROM
copy e:boot* c:boot
Afterwards, just use the boot restore commands to rebuild the bootloader.
