If you can still log into Windows normally, then the steps are rather simple.
☛ For a recovery USB drive:
1. Connect the USB, click on Start > Settings > Update & Security > Recovery in Windows 10, and you will find a Restart now button under Advanced startup section.
2. Tap it and the computer will reboot to Windows 10 recovery environment, you can then choose Recover from a USB to reinstall Windows 10, or choose Advanced options for troubleshooting.
☛ For an installation USB drive:
1. You can connect the previously created installation USB, and select it in File Explorer.
2. Double-click setup.exe in the root directory to run the installer, and follow the wizard to install Windows 10 updates (i.e. in-place upgrade).
Approach 2. Boot Windows 10 from USB flash drive (at startup)
Whether it’s an installation USB or recovery USB, you can boot from it during startup to rescue a faulty computer. The difference is that the former can be created on a normally working PC and used on another PC, while the latter can usually only be used on the computer where it was created.
To repair or install Windows 10 from USB during startup, you can change BIOS/UEFI settings to make the bootable media on top of the boot order list.
1. Connect the USB drive, power on the PC and press the required key to enter BIOS/UEFI. The key is usually F1, F2, F10, F12, Delete. etc. If you are not sure, read the motherboard manual or search the PC model on Internet.
2. Then, find the boot menu and make the bootable USB flash drive the first boot option among all the devices. Save the settings and exit. The computer should restart and boot from the selected USB drive automatically.
3. After selecting the keyboard layout, you can proceed to the next step. With an installation USB, you will be lead to the process of clean installation; and with a recovery USB, you will enter Windows recovery environment for further opertion.
Note: USB booting on UEFI systems requires the “Secure Boot” option to be disabled. If your computer uses UEFI, you need to temporarily disable the option. In addition to “Secure Boot”, it may be called by other names like “Legacy Boot”, “Legacy Support”, “CSM”, “Launch CSM”, etc.
