<aname="l6"></a>Dual booting with another operating system is the best way to use ZealOS. It is often used in a virtual machine because it
<aname="l7"></a>won't boot natively on some machines, though. For native dual booting, you need a partition for ZealOS. Windows often comes
<aname="l8"></a>with a restore disk that does not allow repartitioning. It's recommended to connect a spare additional hard drive and use the </span><spanclass=cF2>B
<aname="l9"></a>IOS</span><spanclass=cF0> to select which drive to boot.
<aname="l11"></a>The </span><ahref="https://tomawezome.github.io/ZealOS/Misc/OSInstall.html#l1"><spanclass=cF4>::/Misc/OSInstall.CC</span></a><spanclass=cF0> script will automate much of this. It runs if you boot the CD/DVD-ROM.
<aname="l13"></a>See </span><ahref="https://tomawezome.github.io/ZealOS/Doc/Boot.html#l1"><spanclass=cF4>Boot.DD</span></a><spanclass=cF0> for an overview of booting. See </span><ahref="https://tomawezome.github.io/ZealOS/Doc/Requirements.html#l1"><spanclass=cF4>Requirements</span></a><spanclass=cF0> for supported hardware.

<aname="l21"></a> The first partition will be </span><spanclass=cF2>'C'</span><spanclass=cF0>, second, </span><spanclass=cF2>'D'</span><spanclass=cF0>, etc. ZealOS needs only 1 number to utilize a hard drive -- port.
