## Tested ISOs
A list of tested ISO images can be found [here](docs/Supported_OS.md)
Check and install the required packages (in most cases they should be installed by default):
- tar, bzip2, xz
- sgdisk, wipefs
- mkfs.fat, mkfs.exfat, ...
Go to the directory where you extracted the files and run the following at the console
```sh
$ ./multios-usb.sh -l
```
This command will show you the USB devices available on your system.
To install MultiOS-USB, type the following command, replacing `/dev/sdX` with your chosen device path.
For example:
```sh
$ sudo ./multios-usb.sh /dev/sdX
```
### Image based installation (experimental)
Recommended installation method for Windows. Go to [Releases](https://github.com/Mexit/MultiOS-USB/releases) and download the appropriate file.
Installation details can be found [here](docs/README_image) and in the downloaded archive.
## First use
After installation, copy your ISO files to the `/ISOs` directory and boot your computer from USB.
You can also add your own configuration files to the `/MultiOS-USB/config_priv` directory. They will not be deleted during the automatic MultiOS-USB update.
If you want to change the configuration for a given ISO - copy the one you have chosen from the [config](config) folder, paste into [config_priv](config_priv) and update it according to your needs.
The updated configuration will be detected automatically.
On the first boot with Secure Boot enabled on each new computer, a MultiOS USB certificate must be installed.
Select `MultiOS-EFI` as partition, then browse to the `EFI/cert` directory and select `MultiOS-USB.cer`, `Continue` and confirm (`Yes`) key enrolling.
You can also immediately add certificates (keys) from popular distributions in the same way.
If you want to add a certificate later, you can do it by selecting in the Main Menu:
`EFI Tools -->` and then `Add UEFI key or hash`.
##### Automatic update
To update configuration files, simply type the following command, replacing `/dev/sdX` with your chosen device path.
```sh
$ ./multios-usb.sh -u /dev/sdX
```
##### Manual update
- Remove all files and directories on your USB in `/MultiOS-USB/config/`
- Copy the downloaded files and directories from `config` to the above directory.
