GRUB2 boot stanza for Android x86 7.1 rc1

[Johannes Rohr]

Hi, on my machine with Arch Linux I did not want the Android x86 install to automatically install grub2 because I wasn't sure what this would do to my existing grub2 installation. So I manually created the following boot menu entry:

menuentry 'Android x86' {

savedefault

set root='(hd0,msdos1)'

        search --file --no-floppy --set=root /android-7.1-rc1/system.sfs

        linux /android-7.1-rc1/kernel root=/dev/ram0 buildvariant=userdebug SRC=/android-7.1-rc1 DATA= androidboot.hardware=android_x86

        initrd /android-7.1-rc1/initrd.img 

}

But this immediately sends android into reboot after a few seconds. As it does not pause before the reboot, and console messages just keep flashing by quickly, I can't read what the last kernel message before reboot is. 

Does someone see an obvious flaw in this boot stanza? The partition and directory names should be correct, I double and triple checked them. The partition is an ext4 partition, android-86 is installed alongside an existing arch linux

I did so:

menuentry "Android"{

                        recordfail

                        load_video

                        gfxmode $linux_gfx_mode

                        insmod gzio

                        if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi

                        insmod part_gpt

                        insmod ext2

                        search --set=root --file /android-2017-07-12/kernel

                        linux /android-2017-07-12/kernel  quiet root=/dev/ram0 androidboot.selinux=permissive vmalloc=192M buildvariant=userdebug

                        initrd /android-2017-07-12/initrd.img

}

With android 7 this: 

androidboot.hardware=android_x86

It's not necessary any more

The partition must be ext4

You missed androidboot.selinux=permissive.

androidboot.hardware=android_x86 is unnecessary now.
Could be removed.

SRC=/android-7.1-rc1 could also be eliminated
in your case. (it's auto derived from other cmdline)

I have the similar issue boot from the Grub2Win, the system will stop in there cannot boot success.
My boot menu entry as below:

menuentry 'Android-x86_64 7.1' --class android {
search --file --no-floppy --set=root /android-x86/system.img
linux /android-x86/kernel root=/dev/ram0 buildvariant=userdebug androidboot.selinux=permissive DATA= quiet
initrd /android-x86/initrd.img
}

If you can normal boot, please help to share your boot menu entry for reference.

Thanks for your help! - Stephen
