Hello,
In such a case state of BOOT0 pin will depend on the external conditions. It can 'catch' some disturbances and be either 'H' or 'L' state. Thus it may happened that MCU will not start from internal FLASH (Boot0='L') but it will try to run from system memory (built in bootloader) or internal SRAM. Thus I would strongly recommend to fix the level on this pin during startup process of the MCU.
Best regards,
Artur
