When installing Windows 10, the standard graphical installer usually works fine. However, there are specific scenarios where using the command-line tool diskpart is necessary or superior: diskpart windows 10 install
If you have an older PC or are forced to use "Legacy" boot mode in your BIOS settings, use MBR . select disk 0 clean convert mbr create partition
To erase all existing partitions, data, and hidden formatting on the selected disk, type: clean Use code with caution. diskpart windows 10 install
You can stop after the convert command and let the Windows Setup handle the rest (it will automatically create the necessary partitions), but if you want to do it manually via command line, continue here.
