Hi guys, i have ten computers running os windows 10 pro working completely fine and booting fine. They ask me at work to upgrade the memory, so i bought memory crucial ddr3-1600 4gb. I turned off my computer and installed the memory, but I keep getting the preparing automatic repair loop. even when i put in bootable device and try to boot from it, it doesnt let me. when i take out the two memories I installed and go back to my old memory, the computer boots just fine without the preparing automatic repair issue
Note: 1- i try to enable the xd in bios, but that did not work either
2- i tried this with my other pc's and im running into the same problem
3- all my pc's are lenovo think centre m90p

please guys, does anybody have any idea about how i could fix this issue?
