How to Format Partitions on a Dualboot Windows/Linux

Introduction

When it comes to setting up a dual-boot system, proper partitioning is crucial to ensure both operating systems can function correctly. In this guide, we’ll be focusing on how to format partitions on a dual-boot Windows/Linux system, specifically using a 1TB SSD and a 3TB HDD. We’ll also discuss the benefits of using ext4 versus NTFS and other formats that may be better suited for Linux.

Partitioning the System SSD

The first step in setting up a dual-boot system is to partition the system SSD. In this case, we have a 1TB SSD that we’ll be splitting between Windows 10 and ArchLinux. Here’s an example of how we could partition the drive:

+-------------------------------------------------------------------------------+
|500MB EFI     | 250GB NTFS Windows10  | 250GB ext4 Arch  | 500GB NTFS Shared  |
+-------------------------------------------------------------------------------+

The EFI partition is required for booting the system and should be formatted as FAT32. The Windows 10 partition should be formatted as NTFS, while the ArchLinux partition can be formatted as ext4. This is because ext4 is the default filesystem for most Linux distributions and is known for its stability and performance.

The shared partition can be formatted as either NTFS or a Linux filesystem such as ext4 or btrfs. NTFS is a good choice if you plan on accessing the shared partition primarily from Windows, while a Linux filesystem may be a better option if you plan on accessing it primarily from Linux.

Formatting an Internal Expansion Drive

If you plan on adding an internal expansion drive at a later time, you’ll need to format it before you can use it. In this case, we have a 3TB+ HDD that we’ll be using for storage expansion. Here’s an example of how we could format the drive:

+-----------------+
| 3TB+ exFAT     | 
+-----------------+

exFAT is a good choice for a storage drive as it’s supported by both Windows and Linux and can handle large file sizes. If you plan on using the drive primarily for Linux, you may want to consider formatting it as a Linux filesystem such as ext4 or btrfs.

Benefits of Using ext4 versus NTFS

As mentioned earlier, ext4 is the default filesystem for most Linux distributions and is known for its stability and performance. NTFS, on the other hand, is the default filesystem for Windows and is also supported by most Linux distributions.

One of the main benefits of using ext4 over NTFS is that it’s a journaling filesystem, which means it’s more resistant to data corruption in the event of a power outage or system crash. It’s also optimized for handling small files and has better performance when dealing with large amounts of data.

NTFS, on the other hand, is better suited for handling large files and has better support for file permissions and encryption. It’s also the default filesystem for Windows, which means it’s more widely supported by third-party software.

Ultimately, the choice between ext4 and NTFS comes down to personal preference and usage requirements. If you plan on using your system primarily for Linux, ext4 is a good choice. If you plan on using your system primarily for Windows or have specific requirements for file permissions or encryption, NTFS may be a better option.

Alternative Formats for Linux

While ext4 is the default filesystem for most Linux distributions, there are other options that may be better suited for specific use cases. Here are a few alternatives to consider:

XFS: XFS is a high-performance filesystem that’s optimized for handling large files and large amounts of data. It’s a good choice for systems that deal with large media files, such as video editing or audio production.

Btrfs: Btrfs is a newer filesystem that’s still under development but offers some interesting features such as built-in RAID and snapshotting. It’s a good choice for systems that require advanced features such as data deduplication or online filesystem resizing.

ZFS: ZFS is a filesystem originally developed by Sun Microsystems that’s known for its advanced features such as built-in RAID, snapshotting, and data compression. It’s a good choice for systems that require high levels of data protection and redundancy.

Ultimately, the choice between filesystems comes down to personal preference and usage requirements. If you have specific requirements for data protection or advanced features, it may be worth considering an alternative filesystem to ext4.

Conclusion

Proper partitioning is crucial when setting up a dual-boot system, and choosing the right filesystem is equally important. In this guide, we’ve discussed how to partition a 1TB SSD for a dual-boot Windows/Linux system and how to format an internal expansion drive. We’ve also discussed the benefits of using ext4 versus NTFS and other filesystems that may be better suited for specific use cases. By following these guidelines, you can create a stable and efficient dual-boot system that meets your needs.

It’s generally a good idea to have a separate partition for the EFI boot partition, which should be around 500MB. This will allow you to boot both Windows and Linux from the same drive.

For the main system partition, you can choose either NTFS for Windows or ext4 for Linux. Both file systems have their own advantages and disadvantages. NTFS is the default file system for Windows and is generally more reliable and easier to use, but it doesn’t support some advanced features that ext4 does, such as transparent compression and journaling. Ext4 is the default file system for Linux and is generally more efficient and has better performance, but it may not be fully compatible with Windows.

As for the shared space on the SSD, you can use a file system that is supported by both Windows and Linux, such as exFAT or NTFS. This will allow you to access the shared space from both operating systems.

For the internal expansion drive, you can also use a file system that is supported by both Windows and Linux, such as exFAT or NTFS. ExFAT is a good choice if you want a file system that is simple and easy to use, while NTFS is a good choice if you want a more advanced file system with more features.

Overall, the layout you have proposed looks good. Just make sure to allocate enough space for each operating system and consider the pros and cons of each file system when making your decision.

In summary, when setting up a dual boot with Windows and Linux, it’s a good idea to:

1. Create a separate EFI boot partition for both operating systems.
2. Choose a file system for each operating system that best meets your needs. NTFS is generally a good choice for Windows, while ext4 is a good choice for Linux.
3. Use a file system that is supported by both operating systems for the shared space or any expansion drives, such as exFAT or NTFS.

I hope this helps! Let me know if you have any other questions.

From my personal experience with a Gentoo dual-boot setup, for the same purposes, it is recommended to create 5 primary partitions. These include an EFI System Partition (if you’re using UEFI to boot), a Microsoft Reserved Partition, a Windows C: drive (formatted as NTFS), a Linux root partition (formatted as a standard Linux filesystem such as ext4, XFS, or BTRFS), and a shared data partition (formatted as either NTFS or exFAT).

The EFI partition needs to be formatted as FAT32 and will be automatically created by Windows during installation. The Microsoft Reserved Partition is typically unused, but it is essential for some Windows functions.

The Windows C: drive only needs to be about 32GB, assuming you store most data on the shared partition. The Linux root partition can be small if you choose to use the shared data partition for your home directory.

The shared data partition should ideally be most of your disk space, and NTFS-3G should be used instead of the kernel driver if using NTFS. If using exFAT, it is recommended to use the FUSE driver instead of the Samsung driver. Installing games on exFAT may or may not affect performance compared to NTFS, and installing Linux software on the shared data partition may not be possible unless you add another layer on top.

However, Linux does not waste significant amounts of disk space like Windows, so a full desktop environment including an office suite and development environment can fit in under 8GB of space.
