Computer booting up slow and unable to add files to flash drive

Hi,

Thank you for your interest in Windows 10.

I suggest you to run System Maintenance Troubleshooter.
Follow these steps to run System Maintenance troubleshooter:

• Press Windows key + W and type troubleshooting.
• Select Troubleshooting.
• Select View all on the top left corner.
• Click System Maintenance.
• Follow the on-screen instruction to run the troubleshooter.

I suggest you to place the computer in Clean boot
and check.

Putting your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue. You need to follow the steps from the article mentioned below to perform a Clean Boot:

Note: After clean boot troubleshooting steps, refer to the section "How to reset the computer to start as usual after troubleshooting with clean boot" in the provided link to return your computer
to Normal startup mode.

With regards to USB flash drive as its not working with different computers as well, you may need to get in touch with the USB flash drive manufacturer.

Hope this information is helpful. Please do let us know if you need further assistance, we’ll be glad to assist you.

 

Win 10 booting from DVD or Flash drive

I have upgraded a Lenovo G40-70 from 8 to 8.1 to 10. All is well except I am unable to set either a DVD or Flash drive as the first boot option. I have tried every suggestion on the internet, upgraded my BIOS and nothing works. It always boots from the boot
manager.

The bios says the flash drive is activated, but it still will not boot from the flash drive.
