Le multiboot est un terme informatique qui désigne la possibilité d'installer sur un même ordinateur plusieurs systèmes d’exploitation et de choisir l'un d'eux lors du démarrage de l'ordinateur. Exemple : un multiboot Windows/Linux. Les logiciels permettant un multiboot sont appelés chargeurs d’amorçage (en anglais : boot loader). Le multiboot sert aussi à choisir l'un ou l'autre noyau pour une même distribution. 2 DOGNY CHRISTOPHE 1SIO POD4 TP Multiboot SISR1 Téléchargement des logiciels nécessaire au TP Téléchargement de Disk2VHD Cet utilitaire est utilisé pour faire une image d'un disque physique (une conversion P2V). Disk2vhd permet de convertir le disque à chaud et peut être lancé sur celui-là. Le fait de stocker le vhd sur votre machine fait perdre de la performance à la conversion. Il est conseillé de le sauvegarder sur un volume tiers. Le logiciel va ensuite produire une image au format .vhdx. (Pour EasyBCD, le .vhd , .vhdx et .img est pris en compte. Téléchargement de Disk2vhd sur le site de Windows SysInternals, une suite d’outils d’administration pour l’environnement Windows. 3 DOGNY CHRISTOPHE 1SIO POD4 TP Multiboot SISR1 Téléchargement d’EasyBCD EasyBCD peut enregistrer des entrées dans le Boot Configuration Data de Windows Vista et Windows 7. Windows NT, Windows 2000 et Windows XP sont pris en charge en enchaînant l'amorçage vers NTLDR (NT Loader). DOS, Windows 3.x, Windows 95, Windows 98 et Windows Me sont pris en charge et démarrés via une version modifiée de IO.SYS. Linux et BSD sont supportés et chargés en "chainloadant" vers GRUB et/ou LILO ou en utilisant son module NeoGrub (qui est basé sur GRUB4DOS). 4 DOGNY CHRISTOPHE 1SIO POD4 TP Multiboot SISR1 Téléchargement d’un VHD de Windows XP VHD (Virtual Hard Disk) est un format de fichier utilisé pour décrire un disque dur virtuel. Ce format est typiquement utilisé pour enregistrer dans un fichier le contenu d'un disque dur d'une machine virtuelle. On télécharge directement un VHD de Windows XP sur le site suivant : http://www.askvg.com/download-free-windows-xp-vista-and-windows-7-vhd-image-files-for-microsoft- virtual-pc/ A noté : Il serait aussi possible de créer l’image directement avec Disk2vhd mais ayant des contrainte d’espace disque, je me suis rabattu sur Windows XP, qui demande moins de place. Le fichier téléchargé est un .exe, qui permet par son exécution d’extraire le VHD de Windows XP. 5 DOGNY CHRISTOPHE 1SIO POD4 TP Multiboot SISR1 Configuration de Windows XP dans le BCD de Windows 7 A l’aide de EasyBCD, on ajoute simplement Windows XP a la configuration de démarrage de Windows. Windows XP n’étant pas installé à part entière sur la machine, le .vhd sera donc considéré comme une image disque dans la section « Média portable/externe. On indique le chemin de notre image de Windows, on modifie le nom, et on l’ajoute au BCD. 6 DOGNY CHRISTOPHE 1SIO POD4 TP Multiboot SISR1 On voit bien désormais dans le menu de démarrage les deux Windows, avec Windows 7 définit par défaut. On enregistre et on redémarre la machine virtuelle. 7 DOGNY CHRISTOPHE 1SIO POD4 TP Multiboot SISR1 Test d’exécution du multiboot Le Windows Boot Manager s’affiche et nous demande de choisir sur quel OS on désire booter. 8 DOGNY CHRISTOPHE 1SIO POD4 TP Multiboot SISR1 Windows XP démarre avec succès 9 DOGNY CHRISTOPHE .

  • Windows Vista Startup Process
    Windows Vista startup process From Wikipedia, the free encyclopedia The startup process of Microsoft's Windows Vista and Windows Server 2008 operating systems is slightly different from previous versions. Contents 1 Boot sequence 2 Windows Boot Manager 3 Boot Configuration Data 4 winload.exe 5 See also 6 References 7 External links Boot sequence The sequence of booting Windows Vista is slightly different from any previous version of Windows that uses the NT kernel. First, when the computer is switched on, either the BIOS or the EFI is loaded. In the case of a BIOS system, the MBR of the boot disk, which can be a hard drive or external media, is accessed, followed by the boot sector of the drive or of relevant hard disk partition. This boot sector then loads the rest of the boot blocks. For Windows Vista, the boot sector loads the Windows Boot Manager (Filename:Bootmgr.) which accesses the Boot Configuration Data store and uses the information to load the final stage, the Operating System. Windows Boot Manager The Windows Boot Manager reads the Boot Configuration Data and "displays an operating system selection menu",[1] and is thus, in some respects, equivalent to the boot selection menu functionality of NTLDR in prior versions of Windows NT. To maintain a consistent boot experience, on Extensible Firmware Interface systems, which also have a boot manager of their own, the Windows Boot Manager, and hence all of the installed Windows operating systems that can be booted using it, appear as a single entry on the EFI boot manager menu.
