Bare Metal, Virtual Machine, or Dual Boot?
After deciding to use Ubuntu 26.04, the next key question is: how should you deploy it? You can install Ubuntu as the sole operating system on bare metal, run it in a virtual machine, or set up a dual boot alongside your existing Windows or macOS. These three approaches differ significantly in terms of performance, convenience, risk, and suitability. This article will analyze the pros and cons of each approach to help you make the best choice for your situation.
Core Comparison of the Three Approaches
| Dimension | Bare Metal (Dedicated) | Virtual Machine | Dual Boot |
|---|---|---|---|
| Performance | 100% (native) | 70-90% (overhead) | 100% (native, only one OS runs at a time) |
| GPU Performance | 100% | 30-50% (virtual GPU) | 100% |
| Installation Risk | Low (overwrites existing OS) | No risk | Medium (involves partitioning and boot loader) |
| Difficulty | Simple | Simple to moderate | Moderate to difficult |
| System Switching | Cannot switch | Instant (window switching) | Requires reboot |
| Hardware Access | Full | Limited (USB requires passthrough) | Full |
| Disk Space | Uses the entire disk | Only uses allocated virtual disk | Requires a dedicated partition |
| Reverting | Requires reinstalling original OS | Just delete the VM | Delete partition and repair boot loader |
| Suitable for Gaming | Yes | No | Yes |
| Suitable for Development | Yes | Yes | Yes |
| Suitable for Beginners | Requires commitment | Best fit | Requires some experience |
Bare Metal Installation (Dedicated)
Install Ubuntu 26.04 as the only operating system on your computer. This is the simplest and most direct approach, and it provides the best performance.
Advantages
- Best performance — all hardware resources are dedicated to Ubuntu with no virtualization overhead
- Full hardware support — GPU, Wi-Fi, Bluetooth, fingerprint reader, and all other hardware work directly
- Simplest installation process — select “Erase entire disk” and the installer handles everything
- No boot conflicts — no issues with GRUB being overwritten or boot menu disappearing
- Best gaming experience — GPU is driven directly, ideal for Steam games
Disadvantages
- Cannot use Windows/macOS exclusive software — such as the Adobe suite, Microsoft Office desktop version (web versions are available as alternatives)
- Requires full commitment — switching back means reinstalling the original OS
- Some hardware may not be supported — very few laptop fingerprint readers, infrared cameras, etc. may lack Linux drivers
Best For
- Developers using Ubuntu as their primary system
- Users who don’t depend on Windows/macOS exclusive software
- People with multiple computers who can dedicate one to Ubuntu
- Users ready to fully embrace the Linux ecosystem
Virtual Machine Approach
Run virtualization software within your existing operating system and install Ubuntu inside a virtual machine. This is the lowest risk and most flexible approach.
Recommended Virtualization Software
Different host platforms have different optimal choices:
| Host Platform | Beginner Friendly | Best Performance | Notes |
|---|---|---|---|
| Windows | VirtualBox | VMware Workstation | VirtualBox is completely free and easy to configure; VMware has better performance |
| macOS (Intel) | VirtualBox | VMware Fusion | Both can be used for free |
| macOS (Apple Silicon) | UTM | Parallels Desktop | UTM is free; Parallels has better performance but requires payment |
| Linux | GNOME Boxes | QEMU/KVM + virt-manager | Boxes creates VMs with one click; KVM performance is near-native |
If your host is Linux, we strongly recommend KVM/QEMU + virt-manager. KVM is a virtualization solution built into the Linux kernel, with performance far exceeding VirtualBox and nearly matching bare metal. Installation command: sudo apt install virt-manager qemu-kvm libvirt-daemon-system.
VirtualBox Quick Start
VirtualBox is the most beginner-friendly virtualization solution. Here are the key settings for creating an Ubuntu VM:
| Setting | Recommended Value | Notes |
|---|---|---|
| Type | Linux | — |
| Version | Ubuntu (64-bit) | — |
| Memory | 4096 MB or more | At least 4 GB, 8 GB recommended |
| Processors | 4 cores | Don’t exceed half of the host’s physical cores |
| Virtual Hard Disk | 50 GB, dynamically allocated | VDI format is fine |
| Video Memory | 128 MB | Maximum value |
| 3D Acceleration | Enabled | Improves desktop animation smoothness |
| Network | Bridged Adapter | Puts the VM on the same network as the host |
Virtual Machine Limitations
- Poor 3D graphics performance — not suitable for gaming and 3D applications
- USB devices require manual passthrough — printers, scanners, etc. need extra configuration
- Consumes host resources — the host needs at least 12 GB of RAM for a comfortable experience
- Cannot test real hardware compatibility — the VM uses virtual hardware
Dual Boot
Install both Ubuntu and another operating system (usually Windows) on the same computer, and choose which one to boot from the boot menu at startup. This approach balances native performance with the flexibility of switching systems.
Windows + Ubuntu Dual Boot
This is the most common dual boot combination, natively supported by the Ubuntu installer. The general process:
- Back up important data in Windows
- Use Windows Disk Management to shrink the volume, freeing up at least 50 GB of unallocated space
- Boot from the Ubuntu installation USB drive
- Select “Install alongside Windows”
- After installation, restart and the GRUB boot menu will list both Ubuntu and Windows
Important notes for Windows + Ubuntu dual boot:
- BitLocker encryption: If Windows has BitLocker full-disk encryption enabled (many brand laptops enable it by default), you must suspend or disable BitLocker before adjusting partitions. Otherwise, Windows may fail to boot and require a recovery key. Check BitLocker status in Windows settings beforehand.
- Windows updates overwriting GRUB: Major Windows updates (such as feature updates) may overwrite the GRUB boot record, causing the computer to boot directly into Windows without showing the Ubuntu option. The fix is to boot from an Ubuntu Live USB and use the
boot-repairtool to repair the boot loader. - Fast Startup: Windows’ Fast Startup feature locks NTFS partitions, which may prevent Ubuntu from properly reading/writing Windows partitions. It is recommended to disable Fast Startup in Windows power settings.
- Time desync: Windows and Ubuntu interpret the hardware clock differently (UTC vs local time), which may cause incorrect time after switching systems. Fix command:
sudo timedatectl set-local-rtc 1.
macOS + Ubuntu Dual Boot
Setting up macOS + Ubuntu dual boot on an Intel Mac is possible but much more complex than with Windows:
- Requires using
diskutilto manually adjust partitions - Requires installing a third-party boot manager such as rEFInd
- Trackpad and Wi-Fi may need additional driver installation
- Not recommended for beginners
For Intel Mac users, if you just want to try Ubuntu, a virtual machine is the better choice. VMware Fusion and VirtualBox both run Ubuntu very well on Intel Macs, avoiding the complexity of partitioning and boot management.
Special Notes for Apple Silicon Macs (M Series)
Apple Silicon Macs (M1, M2, M3, M4 and their Pro/Max/Ultra variants) use a completely different hardware architecture from traditional PCs. The current Linux support situation is as follows:
| Approach | Feasibility | Maturity | Notes |
|---|---|---|---|
| Virtual Machine (Recommended) | Fully feasible | Mature | Use UTM (free) or Parallels (paid) to run ARM64 Ubuntu |
| Asahi Linux Bare Metal | Feasible | Improving | Community project; GPU acceleration and audio support are continuously improving |
| Dual Boot (macOS + Linux) | Limited feasibility | Early stage | Achieved through the Asahi installer; features are not yet complete |
Apple Silicon Mac limitations:
- Since Apple doesn’t publish complete hardware documentation, the Asahi Linux project relies on reverse engineering for hardware support. GPU acceleration is mostly functional now, but Thunderbolt, some audio features, and the camera are still in development.
- Apple Silicon Macs cannot run x86_64 versions of Ubuntu — only the ARM64 (aarch64) version. Ubuntu 26.04 provides an official ARM64 desktop ISO, which is a major advantage.
- If your main purpose is learning and development, using UTM VM + ARM64 Ubuntu on an Apple Silicon Mac is currently the most stable and hassle-free option.
Quick Reference for Each Approach
| Your Situation | Recommended Approach |
|---|---|
| Linux beginner, want to try before committing | Virtual machine |
| Only one computer, can’t lose Windows | Dual boot or virtual machine |
| Want the best Linux gaming experience | Bare metal or dual boot |
| Primarily doing software development | Bare metal (most recommended) or virtual machine |
| Company computer, can’t modify the system | Virtual machine |
| Have a spare computer to experiment with | Bare metal |
| Apple Silicon Mac user | Virtual machine (UTM / Parallels) |
| Need to use both Windows and Linux | Dual boot (requires reboot) or virtual machine (instant switching) |
| Want to revive an old computer | Bare metal (Ubuntu or a lightweight variant like Xubuntu) |
| Server / production environment | Bare metal or KVM virtualization |
If you still can’t decide, the safest path is: use Ubuntu in a virtual machine for 2 weeks first. If after 2 weeks you feel Ubuntu meets your needs, then consider installing it on bare metal (dual boot or dedicated). All skills learned in the VM transfer directly to bare metal.
Migrating from Virtual Machine to Bare Metal
When you’ve built up enough experience in the virtual machine and are ready to migrate to bare metal, here are some practical tips:
- Record the software you’ve installed — run
apt list --installedin the VM to export a list of installed packages - Back up configuration files —
~/.bashrc, personal configs in the~/.config/directory - Export browser data — bookmarks, passwords, etc. can be synced via browser accounts
- No need to migrate the virtual disk — bare metal installation is a fresh install; the VM’s disk image cannot be directly transferred
- Choose the right installation method — based on the analysis earlier in this article, choose bare metal or dual boot
The migration process is more like “rebuilding your environment with existing experience” rather than “moving house.” With your VM experience, bare metal installation and configuration will be much smoother.
