Q: How do I install SteamOS?
There are two different install methods for SteamOS. '''WARNING: BOTH METHODS WILL ERASE EVERYTHING ON THE MACHINE'''
The easiest method is an image-based install using CloneZilla. You will need to create a SteamOS System Restore USB stick to perform this install. The image provided here requires at least a 1TB disk.The second method is based on the Debian Installer. It requires multiple configuration steps:
- Format a 4GB or larger USB stick with the FAT32 filesystem.
- Use "SYSRESTORE" as the partition name
- Unzip the contents of SYSRESTORE.zip to this USB stick to create the System Restore USB stick
- Put the System Restore USB stick in your target machine.
- Boot your machine and tell the BIOS to boot off the stick. (usually something like F8, F11 or F12 will bring up the BIOS boot menu).
- Make sure you select the UEFI entry, it may look something like "UEFI: Patriot Memory PMAP"
- Select "Restore Entire Disk" from the GRUB menu.
- System Restore will proceed automatically. When it is complete it will reboot into your freshly re-imaged SteamOS
- Unzip the SteamOSInstaller.zip file to a blank, FAT32-formatted USB stick.
- Put the USB stick in your target machine.
- Boot your machine and tell the BIOS to boot off the stick. (usually something like F8, F11, or F12 will bring up the BIOS boot menu).
- Make sure you select the UEFI entry, it may look something like "UEFI: Patriot Memory PMAP"
- Pick "Automated Install" from the next menu.
- The rest of the installation is unattended and will repartition the drive and install SteamOS.
- After installation is complete, log onto the resulting system (using the Gnome session) with the predefined "steam" account. The password is "steam".
- Run steam, accept the EULA, and let it bootstrap.
- Logoff the steam account
- Log on with the "desktop" account.
- The password is "desktop"
- From a terminal window, run ~/post_logon.sh. This will prompt for a password - enter "desktop".
- This script will perform the post-install customizations, delete itself, then reboot into the recovery partition capture utility.
- Confirm "y" to continue and the recovery partition will be created. When it is finished, reboot into your freshly installed SteamOS.
