Perso, je toucherais pas au MBR, genre édit hexa...
Tout est sur le CD de Windows. Démarrer en mode récupération. Deux outils te seront utiles : fixboot et fixmbr, dont voici les infos de MS :
FIXBOOT
fixboot drive name:
Use this command to write the new Windows boot sector code on the system partition. In the command syntax, drive name is the drive letter where the boot sector will be written. This command fixes damage in the Windows boot sector. This command overrides the default of writing to the system boot partition. FIXBOOT is supported only on x86-based computers.
FIXMBR
fixmbr device name
Use this command to repair the master boot record (MBR) of the boot partition. In the command syntax, device name is an optional device name that specifies the device that needs a new MBR. Use this command if a virus has damaged the MBR and Windows cannot start.
WARNING: This command can damage your partition tables if a virus is present or a hardware problem exists. Using this command can result in inaccessible partitions. Microsoft recommends that you run antivirus software before you use this command.
You can obtain the device name from the output of the map command. If you do not specify a device name, the MBR of the boot device is repaired, for example:
fixmbr \device\harddisk2
If FIXMBR detects an invalid or non-standard partition table signature, FIXMBR prompts you for permission before rewriting the MBR. FIXMBR is supported only on x86-based computers.
