The OP's Inspiron 5570 (2017) likely shipped in UEFI mode with Secure 
Boot and GPT.  It should offer Legacy mode, which the Debian installer 
should detect and use MBR partitioning.

MBR works well with my imaging strategy because I only need to backup/ 
restore the first ~15 MB of each OS device.  GPT would require me to 
also deal with the backup partition table, whose location can change if 
the source device and destination device are different sizes.
