#Manual Install on Linux

Create a directory at / as /blissos

1. Extract initrd.img, ramdisk.img, kernel and system.* from your desired blissOS ISO into the /blissos directory. ramdisk.img can be ignored for Android 10 and newer as it is already merged into the system (system-as-root).
2. Make a directory called /blissos/data. This will only work for ext4 filesystems, for NTFS and other filesystems or if you are having bootloop you need data.img, can be created with make_ext4fs.
3. Create a new grub entry with this the following code:

menuentry "BlissOS (Default) w/ FFMPEG" { 
    set SOURCE_NAME="blissos"
    search --set=root --file /$SOURCE_NAME/kernel 
    linux /$SOURCE_NAME/kernel FFMPEG_CODEC=1 FFMPEG_PREFER_C2=1 quiet root=/dev/ram0 SRC=/$SOURCE_NAME  
    initrd /$SOURCE_NAME/initrd.img
}

menuentry "BlissOS (Intel) w/ FFMPEG" { 
    set SOURCE_NAME="blissos"
    search --set=root --file /$SOURCE_NAME/kernel 
    linux /$SOURCE_NAME/kernel HWC=drm_minigbm_celadon GRALLOC=minigbm FFMPEG_CODEC=1 FFMPEG_PREFER_C2=1 quiet root=/dev/ram0 SRC=/$SOURCE_NAME  
    initrd /$SOURCE_NAME/initrd.img
}

menuentry "BlissOS PC-Mode (Default) w/ FFMPEG" { 
    set SOURCE_NAME="blissos"
    search --set=root --file /$SOURCE_NAME/kernel 
    linux /$SOURCE_NAME/kernel  quiet root=/dev/ram0 SRC=/$SOURCE_NAME  
    initrd /$SOURCE_NAME/initrd.img
}

menuentry "BlissOS PC-Mode (Intel) w/ FFMPEG" { 
    set SOURCE_NAME="blissos"
    search --set=root --file /$SOURCE_NAME/kernel 
    linux /$SOURCE_NAME/kernel PC_MODE=1 HWC=drm_minigbm_celadon GRALLOC=minigbm FFMPEG_CODEC=1 FFMPEG_PREFER_C2=1 quiet root=/dev/ram0 SRC=/$SOURCE_NAME  
    initrd /$SOURCE_NAME/initrd.img
}

dd if=/dev/zero of=data.img bs=1 count=0 seek=8G
sudo mkfs.ext4 -F data.img

Alternatively, one can use truncate

truncate -s 8G data.img
mkfs.ext4 -F -b 4096 -L "/data" data.img

Here are some additional tips for installing BlissOS on Linux:

• Do not try to install Bliss OS on exotic linux filesystems such ZFS, XFS, BtrFS, currently not every filesystem has built-in support in the Bliss OS kernel, ext4 is supported. If you install it on an unsupported filesystem, it will be stuck at Detecting Android-x86.... You will probably have to compile your own kernel and use a modified initrd.img to boot from other filesystems.
• If you want read-write /system or being able to make changes to the system, simply extract system.img from system.img using a tool that support Zstandard compressed squashFS images. It can also be mounted.
• For data.img, it would be good to repair/check filesystem regularly using command e2fsck -f data.img.

!!ATTENTION!! Bliss OS 14.3 and below versions also support Jaxparrow's Android-x86 Installer for Linux. Source can be found here: https://github.com/jaxparrow07/Androidx86-Installer-Linux
