I know this works with Snow Leopard, but I'm not sure about booting Lion in Virtualbox. My suggestion is: Acquire a Snow Leopard iso image.

Pour installer windows sur un disque dur en usb bootable (a coup sur) il te faut modifier l'installateur d'XP avec nlite par ex afin de changer quelques fichiers, une fois ton systeme installer sur ton disque dur il te faut brancher ton disque dur externe le faire croire qu'il est un lecteur interne (a laide de driver made in hitachi si mes souvenir son correct) et enfin faire un clone de ton systeme sur le disque dur externe ya de vieux tutos qui en parle. Gorilla 5 Film Production Software Serial there. Personnellement je me dis que le systeme risque de pas etre super reactif, du fait que je trouve que windows merde pas mal avec l'usb et que le debit risque den prendre un coup.

As far as I know, the only way to properly create a bootable Lion disc/disk is to use Disk Utility on a working Mac. However, the other option is to use a VM to run OS X temporarily (scroll down for that info). On a Mac: • Download Lion from the Mac App Store. The installer should show up in your Applications folder. Download My Box Storage here.

• Right-click on the installer and hit 'Show Package Contents'. Navigate to Contents >SharedSupport and look for a file called 'InstallESD.dmg'. • Open up Disk Utility and drag the DMG file into the left-hand sidebar. If you're burning it to a DVD, insert your DVD, select the disk image in the sidebar, and hit the 'Burn' button. Skip down to the last step to use it.

• If you want to burn Lion to a USB flash drive, plug it in and click on it in the left-hand sidebar in Disk Utility. Go to the Partition tab and select '1 Partition' from the dropdown menu. Choose 'Mac OS Extended (Journaled) on the left. • Hit the Options button under the partition table and choose 'GUID Partition Table'. You'll need this to make the drive bootable on a Mac. Hit the Apply button when you're done to format your drive (note: it will erase everything on the drive). • Click on the 'Restore' tab, choose the InstallESD.dmg file as the source and your flash drive as the destination.

Hit the Apply button and it will create your bootable USB drive. • Reboot into OS X and hold the option key when you hear the startup chime.

You can boot into your DVD or flash drive from there. On a PC I know this works with Snow Leopard, but I'm not sure about booting Lion in Virtualbox. My suggestion is: • Acquire a Snow Leopard iso image • Use to convert the Lion dmg into an iso • On Virtualbox click 'New' • Choose OS as Mac OS X and click on 64bit or 32 bit (depending on your system) Snow Leopard • Choose VDI as storage and click next • Click on Dynamically Allocated space • Give 4096 MB of Ram for optimum performance or you can also give 2048 • Once finished click on the Virtual OS you just created and click on settings.

• Go to storage and click on the disk below the vdi storage. • Click on the empty disk button on the right side of the window. • Choose the.iso file you converted earlier. • Just click ok and start the Virtual OS.
