Hello everyone, I need some assistance. Recently I made some adjustments to my computers and swapped a few components. I have two Lenovo ThinkCentre SFFs—one with M92p and the other with M82. I replaced the CPU (i7-3770) and RAM (12GB DDR3 1333MHz) from the M92p to the M82, and it worked fine. Then I took the old parts from the M82 (i5 3570, 8GB DDR3 1333MHz) and put them back into the M92p. Except for the motherboard, which is original. Now when I try to turn it on, the logo appears but it doesn’t boot properly—it just stays stuck. I also have an HDD with Windows 11, a SSD with Windows 10, and a USB with Ventoy. Nothing boots at all. When I disconnect everything, it shows the "no OS found, restarting in 1 sec" message. I’ve tried different RAM slots, changed the CPU, adjusted the power supply, used or not a GPU. If you have any suggestions, please share them. Thanks a lot! By the way, sorry for my language issues.

It appears the system is configured for CSM with UEFI boot support. The machine might lack UEFI functionality, preventing it from locating Windows installations. Consider adjusting the BIOS settings to enable secure boot and UEFI, and ensure the SATA drives are activated for booting.
