When you use WinToHDD to install or clone Windows, you can select a partitioning scheme to allow WinToHDD to automatically format the target hard disk. In some cases, however, you may want to use a special partition layout scheme to suit your situation, in which case you need to manually prepare the partitions on the target hard disk. This user guide focuses on how to manually prepare partitions on the target hard disk when using WinToHDD to install or clone Windows, so please read this guide carefully.
How to manually prepare partitions when using WinToHDD to install or clone Windows?
- Booting BIOS-based computers: Please convert the hard drive to MBR partition scheme and create the system and boot partitions. The system partition can be FAT32 or NTFS format and the boot partition must be NTFS format. The system partition and boot partition can be the same partition.
- Booting UEFI-based computers: Please convert the hard drive to GPT partition scheme and create the EFI system partition (ESP) and boot partition. The EFI system partition must be FAT32 format and the boot partition must be NTFS format.
Tips:
- Both the system and boot partition must be primary partition, and we recommend using Windows built-in Disk Management (diskmgmt.msc) to partition and format the disk. If you use a third-party partitioning tool to format the partitions, Windows may not boot properly.
- The destination boot partition must be 20% larger than the used space on source boot partition.
- If the destination system partition is FAT32 format, then it must be greater than or equal to 40 MB and less than or equal to 32 GB. (The recommended size is 500 MB.)
- If you have formatted the wrong hard disk, you can use our Free Data Recovery Software Hasleo Data Recovery to recover your lost files.
Frequently Asked Questions (FAQ)
A: You may need to manually prepare partitions when you want to use a specific partition layout scheme or when you choose "Keep the existing partition scheme" option in WinToHDD instead of letting it automatically format the destination disk.
A: The system partition contains the boot files needed to start Windows, while the boot partition contains the Windows operating system files. In some cases, they can be the same partition, but in UEFI systems, they are typically separate partitions.
A: While you can use third-party tools, WinToHDD recommends using Windows built-in Disk Management (diskmgmt.msc) to ensure proper partition formatting. Using third-party tools may cause Windows to not boot properly.
A: For UEFI computers, you need to convert the hard drive to GPT partition scheme and create an EFI System Partition (ESP) formatted in FAT32, along with a boot partition formatted in NTFS.
A: The destination boot partition must be at least 20% larger than the used space on the source boot partition to ensure enough space for the cloned Windows installation.
