Did you check with all the USB ports?
I would suggest you to try performing system repair using Windows 10 bootable DVD or USB drive and check if that helps.Initiating repair from CD/DVD may have different results. So, I would suggest to perform the repair again and check.
If you don’t have the bootable DVD or USB drive, please refer to the steps in the article given below to create one and then follow the steps given below.
Create installation media for Windows 10
Once you have made the bootable USB or DVD drive, please follow the steps.
Insert the installation DVD or USB and boot Windows 10 from it.
In the ‘Windows setup’ page, select the ‘language to install’, ‘Time and currency format’ and the ‘keyboard or input method’ and click on ‘next’.
Click on ‘Repair your computer’ and select ‘Troubleshoot’.
Click on ‘Advanced options’ and select ‘Automatic Repair’ and select the operating system.
You might also require to change the boot priority in BIOS in order to allow the computer to boot from CD/DVD.
