You cannot boot an operating system installed on a different, protected PC directly onto your Samsung Galaxy Book 2. Operating systems are tightly coupled with specific hardware components, particularly the motherboard and storage controllers. Attempting to boot a drive from another machine will likely result in a kernel panic, blue screen of death, or failure to initialize critical drivers due to mismatched UUIDs, security keys, and hardware abstraction layers.
The concept of "multi-booting" typically refers to installing multiple operating systems on separate partitions of the *same* physical drive or on separate drives connected to the *same* computer. It does not allow for live-booting a foreign OS environment from a disconnected machine. While you can access the BIOS Setup to change boot order, this only selects which local storage device initializes first; it does not enable network-based or remote-booting of a distinct, locked-down PC's OS image. If you need to use software from another PC, you must either install that software locally, use virtualization, or access the other machine remotely via Remote Desktop or similar tools. This guide clarifies why direct booting is impossible and provides legitimate alternatives for accessing data or environments from other machines.
Why Direct Booting Fails
Modern operating systems, including Windows 10 and 11, rely heavily on hardware-specific configurations. When an OS is installed, it generates unique identifiers such as the Hardware ID (HWID) and stores encryption keys tied to the specific TPM (Trusted Platform Module) chip on the host motherboard. The Samsung Galaxy Book 2 has its own distinct TPM and chipset architecture compared to most other PCs. Even if you connect the internal SSD from another PC to your Galaxy Book 2 via an M.2 adapter, the bootloader will fail because the initial configuration files reference non-existent hardware paths.
Furthermore, modern drives often employ full-disk encryption standards like BitLocker. If the original PC was protected, the drive is encrypted with a key stored in its original TPM. Without that specific TPM, the drive remains locked, and no amount of BIOS configuration can bypass this security feature. You would need the recovery key to unlock the drive, but even then, the OS inside would struggle to load due to driver mismatches for the storage controller, graphics card, and network interface.
BIOS Limitations Explained
Accessing the BIOS Setup on your Samsung Galaxy Book 2 allows you to manage boot priorities, secure boot settings, and virtualization features. To enter the BIOS, restart your laptop and repeatedly press the
F2 key before the logo appears. Inside the BIOS, you might see options for
Boot Mode (UEFI vs. Legacy) and
Secure Boot. These settings control how the firmware validates the operating system loader. They do not provide a mechanism to fetch an OS from a remote network source or to execute code from a physically disconnected, incompatible machine. Changing these settings will not enable you to boot a foreign PC's OS.
Legitimate Alternatives for Multi-Environment Access
If your goal is to run software or use an environment from another PC, consider these reliable methods instead of attempting impossible hardware swaps.
- Remote Desktop Connection: Use Windows built-in Remote Desktop Protocol (RDP) to connect to the other PC over your local network. This allows you to control the other machine's desktop session directly from your Galaxy Book 2. Ensure both devices are on the same network and that Remote Desktop is enabled on the target PC.
- Virtual Machines: Install virtualization software like VMware Workstation Player or VirtualBox on your Galaxy Book 2. You can create a virtual machine and install a fresh copy of the operating system there. This isolates the OS from your hardware, allowing you to run multiple environments simultaneously without hardware conflicts.
- External Storage Migration: If you simply need to transfer files, connect the external drive containing your data to your Galaxy Book 2. Most personal files (documents, images, videos) are portable and do not require the original OS to be accessed. Avoid trying to move application installations, as they are registry-bound and non-portable.

Configuring Secure Boot and UEFI Settings
While you cannot boot a foreign PC's OS, configuring your BIOS correctly ensures that your local operating system runs securely. On the Samsung Galaxy Book 2, navigate to the
Security tab in the BIOS Setup. Here, you can toggle
Secure Boot on or off. For standard Windows 11 usage, keep Secure Boot enabled to prevent unauthorized bootloaders from loading. Disabling it may allow unsigned Linux kernels or older Windows versions to boot, but it does not enable booting from other PCs.
Ensure that
Fast Boot is configured appropriately. Fast Boot skips certain hardware initialization steps to speed up startup. If you are using external USB drives for installation media, you may need to disable Fast Boot or adjust the boot order to recognize USB devices before the internal NVMe drive. However, this applies only to local bootable media created specifically for your current hardware.
Data Recovery and Network Access
If the other PC is inaccessible due to OS failure, focus on data recovery rather than booting the OS itself. Remove the storage drive from the other PC and connect it to your Galaxy Book 2 using a compatible USB-to-NVMe or SATA enclosure. Your Galaxy Book 2 will detect it as an external drive. If the drive is not encrypted, you can browse and copy your files. If it is encrypted with BitLocker, you will need the 48-digit recovery key provided by your Microsoft account or printed backup. Without this key, the data is mathematically inaccessible regardless of the host machine.
For ongoing access to applications and files on the other PC, setting up a shared network folder or using cloud storage services is the most efficient solution. This avoids the complexities of hardware compatibility entirely. If you are dealing with peripheral connectivity issues that might confuse your troubleshooting process, such as charging problems with docks, reviewing guides like

Common Misconceptions About Cross-Device Booting
Many users believe that because USB ports can read data, they can also boot complex operating systems from any source. This is false. The boot process requires a chain of trust starting from the firmware (BIOS/UEFI). The firmware checks the signature of the bootloader against known keys. A bootloader from a different PC will have a different digital signature and hardware context, causing the firmware to reject it immediately.
Another misconception is that cloning a disk image will work across different machines. Disk cloning tools create an exact bit-for-bit copy of a drive. If you clone a drive from PC A to PC B, the resulting system on PC B will likely fail to boot because the HAL (Hardware Abstraction Layer) is still configured for PC A's hardware. Modern Windows versions include a feature called "PnP" (Plug and Play) that attempts to adapt on first boot, but it often fails when major components like the CPU architecture or storage controller type differ significantly. Therefore, always perform a clean installation of the OS when moving to new hardware.
Frequently Asked Questions
Can I use a USB bootable drive from another PC?
No, a bootable USB created for one PC's OS installation media may not work on another due to driver incompatibilities. While some generic Linux live USBs work universally, Windows installation media is often tailored to specific hardware profiles and may fail to initialize properly on a Samsung Galaxy Book 2 if the necessary NVMe drivers are missing from the image.
What happens if I try to boot a BitLocker-encrypted drive from another PC?
The drive will remain locked and unreadable. BitLocker ties the decryption key to the TPM of the original motherboard. Without that specific TPM, the system cannot derive the key needed to decrypt the volume. You must supply the 48-digit recovery key manually, but even then, the OS inside may fail to load due to hardware mismatches.
How do I enter BIOS on my Samsung Galaxy Book 2?
Restart your laptop and immediately start pressing the
F2 key repeatedly until the BIOS Setup screen appears. Do not wait for the Windows logo, as the boot process is too fast for manual entry after that point. Once in BIOS, you can adjust boot order and security settings.
Is virtualization a good alternative to multi-booting?
Yes, virtualization is the safest and most flexible method for running multiple operating systems. Software like VMware or VirtualBox allows you to run guest OS instances within your host Windows environment. This avoids hardware conflicts entirely since the virtual machine abstracts the hardware, providing a stable and isolated environment for testing or running legacy software.
Why does my Galaxy Book 2 show "No Boot Device" with an external drive?
This error usually indicates that the external drive is not formatted with a bootable partition scheme compatible with UEFI, or Secure Boot is blocking it. Ensure the drive is formatted as GPT and contains a valid EFI system partition. Additionally, check if the BIOS is set to ignore external USB boot devices, which is a common default security setting on modern laptops.
