1. Please tell us your problems again.
2. Please send us the photo of SN on the bottom of your pc and the purchase record.
3. Could you please send us these two pictures? (The method of entering the BIOS is to press delete all the time at the boot interface)
1. BIOS save&exit page
2. NVME Configuration in BIOS chipest (path: Chipset→PCH-IO Configuration→NVME Configuration).
It is more convenience for us to help you solve this issue through email.
Looking forward to your information.
Have a nice day!
