For example, most computers have a hard disk that is bootable, but sometimes there is a removable-media drive that has higher boot priority, so the user can cause a removable disk to be booted. In most modern BIOSes, the boot priority order can be configured by the user.
“Administrators must attach a physical keyboard to each affected system, boot into Safe Mode, remove the compromised CrowdStrike update, and then reboot.” In other words, it could be some time ...
