Final answer:
To schedule a disk integrity scan for the next boot in Windows 7, a technician would use the CHKDSK command with appropriate parameters.
Step-by-step explanation:
The command a technician would use in Windows 7 to schedule a disk integrity scan upon the next boot is CHKDSK. The command is executed from the command prompt with additional parameters to schedule the check for the next system startup.
For instance, using chkdsk C: /f /r /x. Here, /f attempts to fix any found errors, /r locates bad sectors and recovers readable information, and /x forces the volume to dismount first if necessary.
