No BOOT1 pin on ST MCU
Not all STM32 MCUs have a pin called BOOT1. Some do, some don't. Either way BOOT1 is usually shared with a GPIO pin so it would not be a separate pin.
Even the bootloader guide should indicate that the specfic MCU you are using has no BOOT1 pin.
Since you are using F030 chip, bootloader is triggered by Pattern 2, not Pattern 1 like you expect.
