partition hard disk to accept linux OS

Have a Dell PC with Windows 10, just heard from an enthusiast about LINUX. Need to know how to get the OS, whether and ho I i need to partition to separate from WinOSetc…i.e. basic start-up, I am only reasonably savvy and NOT GOOD with obscure iinitials. Grateful

Usually the Linux installer will offer to do this for you (eg. In Ubuntu and derivative distros the installer will offer you “Install alongside Windows”) … shrinking the Windows partition automagically to make room.

Your other option would be to manually shrink the Windows partition from within Windows itself … THEN to boot the Linux installation media and tell the installer to use the ‘free space’.

Or the installer will usually also allow you to manually specify the partition scheme.

Which Linux distro were you thinking of using ?
