Hi,
It could be a glitch; I have seen other users get this alert, and it turned out to be a false alarm.
To be sure, access Disk Management and check if all disks are marked as "Healthy." If they are, the recommendation is not to attempt any changes to the EFI partition—it is the boot partition, and altering it could cause Windows to fail and prevent it from booting.
However, if the status is not "Healthy":
Open the Command Prompt (as administrator) and run the command: mountvol X: /S
Then run: chkdsk X: /f
Wait for the process to finish, then run: mountvol X: /D
Open the Command Prompt (as administrator) and run the commands: sfc /scannow and dism /online /cleanup-image /restorehealth; wait for the process to finish and restart the computer.
After the procedure is complete, check the status again to see if it has changed. If it hasn't, leave it as is; it may simply be a glitch.
