If it is a brand new refurb with Windows 10 and you intend to DUAL boot with LL do NOT delete any partitions. You must turn off fast boot, and secure boot, and enable CSM Legacy mode in the BIOS You FIRST must shrink the Windows partition © USING WINDOWS creating a new empty (unformatted) partion on the drive. The LL installer will then format and partition that empty space on the HDD and not ruin your Windows installation.
