J'ai eu un très gros problème en installant boot camp... Tout à commencé avec l'installation de winXP. La première partie semble préparer la partition pour accepter windows (ça se passe avec un écran bleu et du texte comme dans le dos...). On me demande ensuite de redémarrer pour commencer l'installation de XP mais tout le processus recommance en boucle à chaque fois. Impossible de d'installer XP. Après plusieurs tentatives j'ai fini par avoir un écran blanc au démarrage... je tente de redémarrer avec la touche alt pour revenir sous osx mais impossible, il ne se passe rien. Impossible d'éjecter le disque même avec la souris enfoncée au démarrage. Après avoir zappé la pram je peux éjecter le disque mais toujours l'écran blanc. À un certain moment donné je vois apparaître le dossier avec le point d'interrogation qui clignote... j'insère le cd osx de démarrage mais il ne se passe rien, je tente de démarrer sur le cd avec la touche c enfoncé mais encore rien... J'ai essayé plusieurs combinaison de touches pour redémarrer sur une autre partition ou en mode single user mais rien n'y fait! Pas possible de passer en mode target non plus. Je voudrais bien reformater le disque mais comment? Aucun problème pour les données j'ai un backup. Je veux simplement retrouver mon mac!!! J'ai un imac 20" neuf avec clavier et souris sans fils auquel je n'ai malheureusement pas fait la mise à jour du firmware. Je ne pensais pas que c'était nécessaire de faire une mise à jour puisque mon ordi était neuf. Le sav ne semble pas trouver la solution... Qu'est que je peux faire???
Gros problème Boot Camp...

- Date de début
Essayes d'insérer le DVD d'install OS X et de démarrer avec la touche "alt" appuyée, logiquement le DVD devrait apparaître...
La touche alt ne fonctionne pas au démarrage, j'ai zappé la pram, j'ai fait pomme-x et surtout, j'ai essayé de réinitialiser le firmware et c'est impossible. On devrait pouvoir démarrer sur le firmware ou le réinstaller, mais si je suis la procédure apple ça ne fonctionne pas. La méthode ne fonctionne même pas sur un autre iMac 17" qui est en parfait état! Donc la procédure est fausse... Que faire??? J'ai un écran gris au démarrage et l'ordi ne semble même pas aller voir sur le disque dur et lorsqu'il y a un cd dans le lecteur, je l'entend gratter quelques secondes mais c'est tout.
Je suis désespéré!!!
Je suis désespéré!!!
Ça marché!!!
Après une recherche sur le site de Apple voici ce que j'ai trouvé et ça marche. Voici l'info pour ceux qui pourraient rencontrer le même problème:
I had the same problem last month and posted this to the forum a while back. It takes patience, but it is possible to get a Mac frozen on the gray screen back to life.
Unofficial FIx for Unbootable Core 2 Duo Macs following unsuccessful Windows XP installation (Mac OS DVD boot also not working)
By: Jon Glazerman
10/01/2006
v1.0
Hardware affected
Some machines with the Intel Core 2 Duo processor running Boot Camp 1.1.1
Symptoms
At some point during the Windows XP installation, your Mac refuses to boot Windows XP or Mac OS X. When you turn on your computer, you'll see a gray screen. You cannot boot from the DVD drive with the keyboard commands, including "Mac OS X Install Disc 1". Firewire target disk mode also fails. Pressing the option key during boot may briefly produce a mouse pointer but no startup volumes appear and the system freezes. The hard drive has likely been erased and rendered unreadable.
Solution
Since the Mac will not boot the DVD, we'll create an Intel Mac-bootable external installer drive.
What You'll Need:
A working Mac
An external hard drive you are willing to format (Firewire only was tested)
Apple's Disk Utility
Mac OS X Install Disc 1
An installed copy of NetRestore v3.3x , found at http://www.bombich.com/software/netrestore.html (Freeware)
Procedure - on your working Mac
1. Insert Mac OS X Install Disc 1 into your DVD drive.
2. On your hard drive, open NetRestore Helper (see above section if missing)
3. Make sure the "Create Master Image" tab is highlighted.
4. At the Master Disk prompt, select Mac OS X Install Disc 1.
5. Select the "Read-only compressed" radio button.
6. You may check the boxes below to skip checksumming and post-processing at your discretion.
7. Click the lock icon in the lower-left corner of the NetRestore Helper window and supply your Username and Password. Once successful, you'll be able to click the Create Master Image button.
8. You'll be prompted to name and save your install disk image. The image creation process could take 10-40 minutes depending on your Mac's capabilities. After a successful image is made, you may close NetRestore.
9. Connect and turn on your external hard drive if not done already.
10. Open Disk Utility and select your external hard drive in the left column display. In the lower right, look for Partition Scheme. If this says "GUID Partition Table", skip to 15.
Important: To make this external drive bootable on an Intel Mac, we need to make sure it's the proper format. You are about to delete the contents of your external drive. You may wish to create a backup before proceeding.
11. Make certain your external hard drive is selected, and click on the "Partition" tab just below your button bar.
12. Name your external hard drive and select Mac OS Extended (Journaled) format.
13. Toward the bottom of the window, click the "Options..." button. Select "GUID Partition Table" and click OK.
14. Click the Partition button and confirm.
15. Select the Restore tab and drag the disk image you created with NetRestore onto it. Or you may click the Image... button to locate the image of your install disk.
16. Drag your external hard drive partition from the left column into the Destination field. You may optionally check the Erase Destination box and then click the Restore button.
Note: If you have still have the installer disk image open in another application (such as the Finder) you may receive an error from Disk Utility until this image is closed in all other applications.
After verification, you may close Disk Utility.
17. Using the Finder, check to make sure your external hard disk file layout resembles your Mac OS X Install Disc 1 DVD. Big discrepancies may indicate a problem in creating the image or restoring the image.
18. Dismount the external hard drive from your working Mac.
Procedure - on your Core 2 Duo Mac
19. Connect the external hard drive cable to the non-booting Core 2 Duo Mac. You'll want the Mac turned off for booting purposes. Turn on your external hard drive.
20. Turn on your Core 2 Duo Mac while holding the option key. The gray screen will be blank for several seconds, followed by an icon for your external hard drive. You should be able to click on this icon and begin the Mac OS X install process. It may not work on the first try, so you may need to power off the system and try again. Also try a USB keyboard and mouse instead of Bluetooth.
Note: If the Max OS X installer runs, but is having trouble identifying your internal hard drive, launch the Disk Utility first and format it using the GUID Partition Table before continuing.
At this point, your Mac should be able to read your second install disk from the DVD drive without issue.
I really hope this fix works for you and you can start enjoying your new Mac again. Again, there may be other methods (for example, booting the install DVD from an external firewire DVD drive) but whatever the case, good luck and thanks for reading.
