Yes, flash drives are removable media.
You can do try getting into the BIOS (boot menu) which should let you setup which order you want the boot starting sequence. Default is usually removable media like usb and cd for recovery purposes.
The quickest solution is to not leave usb plugged in. The card you have must have some boot.sys file to trigger the confusion.
A good backup software and partition manager/rescue disk creator is from ACRONIS. You can download the free Western Digital Acronis True Image. As long as you have a western digital drive. Most computers use WD brand for drives.
Another company for backup and drive management is EaseUS they offer free tools for personal use.
