Dual Boot #22

Closed ganesshkumar closed 10 years ago

ganesshkumar commented 10 years ago

Is dual boot supported. I didn't any way(in default and custom installation) to dual boot along with my existing OS

ganesshkumar commented 10 years ago

If it is possible, please update the installation page accordingly.

As it is stated on the installation page: WARNING: Both installation methods will erase all content on the target computer

So far it is not possible. What might work (the same with Windows) is installing SteamOS first and then another Linux distro like Ubuntu (no guarantee).

You need to edit the default.preseed file on the root of the install media. Remove the bottom section designated to partitioning. This stops the installer automatically partitioning the drive.

Manual install using the pre-configured image:

wget "http://repo.steampowered.com/download/SYSRESTORE.zip"

All following commands assume:

Install the partclone and unzip packages. On Debian/Ubuntu that'd be:

apt-get install partclone unzip

Unpack SteamOS:

unzip -p SYSRESTORE.zip partimag/SteamOS/sda2.ext4-ptcl-img.gz.aa | gzip -d -c | partclone.restore -C -s - -O SteamOS_root.img
unzip -p SYSRESTORE.zip partimag/SteamOS/sda5.ext4-ptcl-img.gz.aa | gzip -d -c | partclone.restore -C -s - -O SteamOS_home.img
truncate -o -s 2500096 SteamOS_root.img
truncate -o -s 54889472 SteamOS_home.img
mkdir SteamOS_root SteamOS_home
mount SteamOS_root.img SteamOS_root
mount SteamOS_home.img SteamOS_home
rsync -aAXv SteamOS_root/* /mnt/SteamOS --exclude=/lost+found
rsync -aAXv SteamOS_home/* /mnt/SteamOS/home --exclude=/lost+found
# (Optional steps) clean up:
umount SteamOS_root SteamOS_home
rm -r SYSRESTORE.zip SteamOS_root.img SteamOS_home.img SteamOS_root SteamOS_home

Edit fstab:

sed -i /mnt/SteamOS/etc/fstab -e "19d" -e "8,17cLABEL=SteamOS   /               ext4    errors=remount-ro   0       1"

Finally add SteamOS to your bootloader. I use Syslinux, so did the following:

cp -an /mnt/SteamOS/boot/{vmlinuz-3.10-3-amd64,initrd.img-3.10-3-amd64} /boot/
cat <<EOF >> /boot/syslinux/syslinux.cfg

LABEL steam
    MENU LABEL SteamOS
    LINUX ../vmlinuz-3.10-3-amd64
    APPEND root=/dev/disk/by-label/SteamOS ro quiet splash nomodeset fbcon=vc:2-6
    INITRD ../initrd.img-3.10-3-amd64
EOF

SteamOS now has ISO support, meaning you can install via DVD and do an Expert Install, just like Debian.

Direct download link.

Closing the issue.
