If you can get to the recovery console you can repair your mbr with the "fixmbr" command. Heres some more schtuff:
Using the Command Console
-------------------------
After you start the Recovery Console, you receive the following message:
Windows NT(TM) Boot Console Command Interpreter.
WARNING:
This is a limited function command prompt intended only as a system recovery
utility for advanced users. Using this utility incorrectly can cause serious
system-wide problems that may require you to reinstall Windows NT to correct
them.
Type 'exit' to leave the command prompt and reboot the system.
1: C:\WINNT
Which Windows NT installation would you like to logon to (enter to abort)?
After you enter the number for the appropriate Windows 2000 installation, enter
the Administrator account password. Note that if you use an incorrect password 3
times, the Recovery Console quits. Also, if the SAM database is missing or
damaged, you are not be able to use the Recovery Console because you cannot be
properly authenticated. After you enter your password and the Recovery Console
starts, typing "exit" restarts your computer.
Restrictions and Limitations of the Command Console
---------------------------------------------------
From the Recovery Console you can only use the following folders:
- The root folder.
- The %SystemRoot% folder and the subfolders of the Windows 2000 installation
you are currently logged in to.
- The Cmdcons folder.
- Removable media drives such as CD-ROM drives.
NOTE: If you try to obtain access to other folders, you receive an "Access
Denied" error message. Also, while in the Recovery Console you cannot copy a
file from the local hard disk to a floppy disk. You can copy a file from a
floppy disk or CD-ROM to a hard disk, and from one hard disk to another hard
disk.
Available Commands
------------------
HELP:
HELP lists all of the following supported commands:
ATTRIB DELETE FIXBOOT MD TYPE
CD DIR FIXMBR MKDIR SYSTEMROOT
CHDIR DISABLE FORMAT MORE
CHKDSK DISKPART HELP RD
CLS ENABLE LISTSVC REN
COPY EXIT LOGON RENAME
DEL EXPAND MAP RMDIR
CHKDSK drive /P /R
Checks, and if needed, repairs or recovers a drive. Also marks bad sectors and
recovers readable information.
drive specifies the drive to check. The /P switch instructs CHKDSK to do an
exhaustive check of the drive even if the drive is not marked with problems and
corrects any errors found. The /R switch locates bad sectors and recovers
readable information. Note that specifying the /R switch implies the /P switch.
CHKDSK may be specified without arguments, in which case the current drive is
implied with no switches. Optionally, the listed switches are accepted. The
CHKDSK command requires the Autochk.exe file. CHKDSK automatically locates this
file in the bootup folder. This would typically be the Cmdcons folder if the
Command Console was pre-installed. If it cannot be found in the bootup folder,
CHKDSK tries to locate the Windows 2000 CD-ROM installation media. If the
installation media cannot be found, CHKDSK prompts you to provide the location
of the Autochk.exe file.
.
FIXBOOT:
FIXBOOT drive name:
Writes new Windows 2000 boot sector code on the boot partition. This fixes
problems where the Windows 2000 boot sector is corrupted. The Emergency Repair
process also fixes the boot sector.
drive name: Drive letter where the boot sector will be written. This overrides
the default of writing to the system boot partition. The FIXBOOT command is only
supported on the x86 platform.
FIXMBR:
FIXMBR device name
Repairs the master boot record (MBR) of the system partition. This is used in
scenarios where a virus has damaged the MBR and Windows 2000 cannot start.
WARNING: This command has the potential to damage your partition tables if a
virus is present or a hardware problem exists. This command may lead to
inaccessible partitions. Microsoft suggests running anti-virus software before
using this command.
device name: Optional device name that specifies the device that needs a new MBR.
The name can be obtained from the output of the MAP command. If this is left
blank, the boot device's MBR is fixed. For example:
FIXMBR \device\harddisk2
If FIXMBR detects an invalid or non-standard partition table signature, it
prompts you for permission before rewriting the MBR. The FIXMBR command is only
supported on the x86 platform.

hope this helps.
