✅ Hi!
Today I suggest you watch a video tutorial on how to install Windows 10 or 11 on any external USB drive, I will use a USB flash drive with a capacity of about 250 GB.
After the end of the process, you can connect this USB flash drive to any computer, and Windows 10 or 11 will work from this USB flash drive, even if the computer does not have a working C drive, and you need to restore it, remove viruses from the operating system, or transfer important data from a locked computer, if you forgot your Windows password.
