Скачать или смотреть Windows 11 on Portable SSD – Dual Boot Without Touching Your NVMe

Ever wanted to run Windows 11 from an external SSD without messing up your existing Linux installation or bootloader? In this video, I’ll show you step-by-step how I installed Windows 11 onto a portable SSD using the DISM + bcdboot method — no dual-boot conflicts, no overwritten EFI, and full portability.

Here’s what I cover:
✅ Safely removing internal NVMe drives to protect Arch Linux
✅ Booting into Windows 11 LTSC setup with Ventoy
✅ Using diskpart to partition the external SSD (EFI + NTFS)
✅ Applying the Windows image manually with DISMs
✅ Writing boot files with bcdboot
✅ First boot into Windows 11 from USB SSD
✅ Reassembling NVMe drives and confirming Linux + Windows coexist peacefully

With this method, you can keep your Linux system completely untouched while having a fully portable Windows 11 installation on an external SSD. Boot Windows only when you need it — directly from your BIOS/UEFI boot menu.
