| - | First step is to **make a bootable USB of your favorite Linux or *BSD flavor**, in which you can install Qemu. Persistency USB is recommended.

USB persistency is recommended, though normal USB without persistency can also be used if Qemu can be installed on RAM, as Qemu isn't necessary after a successful installation. |
| - | Second step is to **boot target machine with live USB, set up network, download and install Qemu**. Alternatively, if there are network issues with the live USB, Qemu can be installed by downloading packages or source first. Don't worry, Internet connection wouldn't be needed during MINIX install. | + | * Second step: **boot the target machine with your live USB, set up the network, then download and install Qemu**. Alternatively, if there are network issues with the live USB, Qemu can be installed by downloading its packages or sources separately, along with the Minix ISO (see below), and then copied to the bootable USB disk. Don't worry, an Internet connection won't be necessary during the MINIX install. |
| - | Third step is to **download iso** from [[http://www.minix3.org/download|here]] and save it in your persistent USB or any normal FAT USB. If having network issues, download it before second step. **Save it as normal iso file**, don't do anymore. | + | * Third step: **download the Minix ISO** from [[http://www.minix3.org/download|this location]] and save it in your persistent USB or any normal FAT USB. If there are network issues, download it before the second step (as mentioned above). **Save it as normal ISO file.** You're now ready to perform the installation. |

This is the drive where Minix is going to be installed. An OpenBSD live USB is used in this guide. If using NetBSD, change //wdXc// to //wdXe//.

This is very important, **the idea is to point to whole physical hard disk, not to a partition!** The //format=raw// part is to bypass the qemu protection of the MBR sector of the target disk: the installation program in the VM need to write Master Boot Record and Partition Boot Sector in the hard disk to boot the kernel.
