Specify your preferences for the virtual hard disk that Fusion will create for your virtual machine.
Virtual Hard Disk Options
- Specify the disk size. Fusion will display a suggested size that's based on the OS you chose earlier. For Windows Vista, 20 GB is a good choice.
- Click the ‘Advanced Disk Options’ disclosure triangle.
- Place a check mark next to any of the advanced disk options you would like to use.
- Allocate all disk space now. Fusion uses a dynamically expanding virtual drive. This option starts with a small drive that can expand, as needed, up to the disk size you specified above. If you prefer, you can choose to create the full virtual disk now, for slightly better performance. The tradeoff is that you're giving up space that could be used elsewhere until the virtual machine needs it.
- Split disk into 2 GB files. This option is primarily used for FAT or UDF drive formats, which don't support large files. Fusion will split your hard drive into multiple sections that FAT and UDF drives can use; each section will be no larger than 2 GB. This option is only necessary for MS-DOS, Windows 3.11, or other older operating systems.
- Use an existing virtual disk. This option lets you use a virtual disk that you created earlier. If you select this option, you will need to supply the path name for the existing virtual disk.
- Allocate all disk space now. Fusion uses a dynamically expanding virtual drive. This option starts with a small drive that can expand, as needed, up to the disk size you specified above. If you prefer, you can choose to create the full virtual disk now, for slightly better performance. The tradeoff is that you're giving up space that could be used elsewhere until the virtual machine needs it.
- After making your selections, click the ‘Continue’ button.
