# Installation

## Network Installation

The machine you want to install needs to be registered in `sysdb`. To be on bleading edge, you might select the `rhel8_preprod` Puppet environment:
```
FQDN=...
bob node set-attr $FQDN puppet_env=rhel8_preprod
```

Optional you can set `netboot` and RHEL 8.6 installer but that can also be selected manually in be boot menu:
```
bob node netboot $FQDN
bob node set-attr $FQDN ipxe_installer=rhel86install
```
### Installation with UEFI
Start the machine and select network boot (if not already the default), then you get following menu:  
![Grub default menu](installation/grub_default.png)

There select "Install Red Hat Enterprise Linux 8.6"

### Installation with Legacy BIOS 
Start the machine and select network boot (if not already the default), then you get following menu:  
![PXE default menu](installation/pxe_default.png)

There select "Red Hat Enterprise Linux 7 Network Install Menu" to get into the iPXE menu, where you can do also a lot of other stuff.  
![PXE menu selection for iPXE](installation/pxe_select.png)  
(I plan to get rid of above menu as it also breaks automatic installation by `sysdb` configuration).

The iPXE menu is then generated according to `sysdb` and its default depends on the configuration, there, but you may override it manualy:
