Will it affect the subsequent USB drive boot and system reinstallation if the drive in the computer is encrypted by the computer and can only be accessed on that specific computer?

If your drive is encrypted with Bitlocker, the only place the Bitlocker Recovery key is automatically stored is on the associated Microsoft account on the link below, be sure to check any Microsoft account that may have been used on the PC and also any work or school account that may be linked to the PC.

If you ever need to re-install WIndows on the internal encrypted drive, then to remove the encryption, you would need to delete all partitions on the drive before beginning the installation.

Answer 2

In short - no - disk encryption tied to that specific computer normally does not prevent you from booting from a USB drive or reinstalling the operating system. USB boot happens before the installed system and its encrypted data are accessed, so as long as the BIOS or UEFI allows external booting, you can start an installer and perform a clean installation.

What encryption does affect is access to the existing data on the internal drive. If the encryption keys are bound to the hardware or a security chip and you do not unlock or decrypt the disk first, the installer will simply see the existing partitions as unreadable. During reinstallation you can choose to erase or repartition the drive, which removes the encryption along with all stored data.

In some environments, especially corporate-managed devices, firmware policies or secure boot settings may restrict external booting or require an administrative password. In those cases you would need to change firmware settings first. Aside from those configuration limits and the loss of existing encrypted data, encryption itself does not block a normal USB-based reinstall.
