## Preset Layouts
Choose from pre-configured layouts that simulate real operating systems:
**Windows Presets:**
- Windows 11/10 (GPT, EFI + NTFS + Recovery)
- Windows Vista/7/8 (MBR, System Reserved + NTFS)
- Windows 2000/XP (MBR, Single NTFS)
- Windows 98/ME (MBR, Single FAT32)
- Windows 95 (MBR, Single FAT16)
- Windows 3.1 (MBR, Single FAT16)
- MS-DOS (MBR, Single FAT12)
**Linux Presets:**
- Modern Linux (GPT, EFI + Root + Swap)
- Linux with /home (GPT, EFI + Root + Home)
- Classic Linux (MBR, Boot + Root + Swap)
- Minimal Linux (MBR, Single ext4)
**macOS Presets:**
- Modern macOS (GPT, EFI + APFS)
- Legacy macOS (GPT, Single HFS+)
**Custom Layout:**
- Full manual configuration with 1-4 partitions
All presets can be customized during setup or used as-is.

- May not be suitable for all forensic scenarios - May not be suitable for all forensic scenarios
## Multi-Partition Support
Create complex disk layouts with up to 4 partitions:
- Each partition can have a different filesystem
- Mix operating system types (Windows NTFS + Linux ext4)
- Include swap partitions for realistic Linux setups
- The last partition automatically uses remaining space
- Perfect for practicing partition table analysis
