Hello there,
Your machine`s BIOS version should be the lastest.
Here are some solutions:
1、Please repeatedly press delete key as soon as you turn on the PC, go to BIOS. On Save&Exit page, please click Restore defaults, press enter to confirm, then press F4 to save.
2、Repair install: Boot from a Windows USB, select “Repair your computer.”
Clean install: Back up data and reinstall Windows with both 32GB sticks installed. Here is the image https://url.bee-link.cn/74zu
Have a nice day!
