I have a L440 Thinkpad. About 3 years back I pulled out the HDD, put in a SSD. Replaced the optical drive with a HDD caddy. The combination worked really great so far.
Recently I replaced my aging SSD with a new one. Basically I cloned the old SSD to a new one. Now after the reboot, the boot screen shows the message, "configuration changed - Restart the system". It is connected to the HDD caddy. If I remove the caddy, the system boots up fine. But whenever I insert the caddy, the system does not boot anymore. I can't even get to the boot menu. It get's stuck in a boot loop.
So I am trying to understand why this is happening here. Other than a new SSD, the caddy is same all the way. It worked before, so no apparent reason for it to stop working. Unless the BIOS firmware is manually checking for allowed FRU after detecting hardware change. Has anyone faced this problem?
Any help or pointers regarding this is greatly appreciated. Thanks.
