Changing second HDD to SSD
My 7540 came with an SSD for the primary drive and a 1 TB HDD for the secondary. I bought a Crucial 4TB PCIe SSD to replace the HDD. When I install the new SSD in any of the NVME slots, I get a BSOD. When I ran the pre-boot diagnostic, I got an error code 151 Harddrive error. This SSD drive works fine when I install it in an external USB drive case. I tried installing the SSD unformatted, and formatted. The BSOD only shows Kernel Security Check Failure. Is there some kind of configuration somewhere that specifies that the second drive is an HDD?
If I still had hair, I would be pulling it out.

Since the 7540 has multiple M.2 slots for NVMe SSD, you may want to try the Crucial drive in different M.2 slot. If your current storage mode is in RAID, considering to change it to AHCI. Follow proper steps while making the BIOS settings change from RAID to AHCI so you won't have any problem with boot issue https://support.thinkcritical.com/kb/articles/switch-windows-10-from-raid-ide-to-ahci

@Chino de Oro Thank you Thank you Thank you. I had tried all combinations of M.2 slots. I had not tried switching storage mode. Works great, now.
