[Guide] Dualboot (Acer Iconia W700) Windows 8 - Android

[ruagun]

Is it supports ARM-apps on the intel platform??

Yes

 

[alphamale]

I have some very good new guys : the guys over at android x86 released a build that is superior to the Intel IA versions.
The build is Android x86 4.4.4 r2. It supports the Iconia W700 sensors , wifi, sleep and more importantly it provides ARM support
(YAAAAAAAAAAAAAAAY!!!!!).

I will be making a video review very soon.

Which download did you use I tried the IMG and during interactive instillation it tells me I need to format and instillation fails. I tried the iso download and I'm unable to write it flash. I successful got and older version to work but it doesn't have play store or a file explorer nor can I install a file explore

this helped me alot i replaced this with the files from akt android-x86 iso and had change some names in the grub config.


edit: dont try to install xposed!! and hw codec video player like mxplayer dont work. everything else is fine!

edit2:

my aktual grub.cfg looks like this.
i replaced the "android-4.4-RC1" from the "howto" with "android-4.4-r2" (in grub and loopback)

if loadfont /boot/grub/font.pf2 ; then
	set gfxmode=auto
	insmod efi_gop
	insmod efi_uga
	insmod gfxterm
	terminal_output gfxterm
fi

set menu_color_normal=white/black
set menu_color_highlight=black/light-gray
set timeout=0

menuentry "Run Android x86" {
	set root=(hd0,gpt5)
	linux /android-4.4-r2/kernel root=/dev/sda5 androidboot.hardware=android_x86 SRC=/android-4.4-r2
	initrd /android-4.4-r2/initrd.img
}

OK. best new feature! i can hibernate WIndows and on Boot press F12 to enter Bootmanager to boot into Android. on next Reboot i can resume my Work in Windows... really NIZE !!

BUT this works only if external Keyboard is connected

-does anyone know how to force Bootmanager without external Keyboard ???
-there is an Option in bios to Boot D2D recovery with VolumeDown on Boot but this doesnt work (i have the recovery partition deleted)). Any Idea how to trick the Bios that it think that Android Partition is the Recovery Partition and Boot Android with VolumeDown?

I tried the installation and resized the win8 partition with Mini Tool Partition Manager, after that Win8 did not work properly. I cleaned my HDD for a fresh Win8 installation, i added Ubuntu 14.04 and with the help of the sony vaio guide installed Android X86 4.4-r2. Everything is working fine. Now i have grub2 to choose my OS at boot time, but it only works with USB keyboards. When pressing the hardware buttons vol+ and vol- you can see that this is sending keys B and C in grub command line. So i have to find a way to modify grub keyboard layout. C should send "key down" and B "enter" to choose the menu entrys. loading keymaps in my grub is not working, nothing happens. i tried "keymap de" in grub command line. if you want to tryout with grub configurations it is important to add GRUB_TERMINAL_INPUT ="usb_keyboard". by adding "at_keyboard" grub won't boot anything.

ok. got it working...

1. use gummiboot (from android-ia) as main bootloader. because it support w700 volume down/up
2. because gummiboot cant boot efi's from an other partition. i use for a seperat folder with rEFInd for each menuentry in gummiboot

i set rEFInd to manual and with timeout = -1

(this wont work with grub because grub expect its grub.cfg allways in /boot/grub/grub.cfg)

everthing is working with vol+ / vol- hard buttons if you choose this solution for Acer W700 with 120GB SSD

1. clear hard drive
2. install win 8.1 with 70GB partition
3. install Ubuntu 14.04 with 30GB partition
4. copy Android x86 4.4-r2 to 20GB partition
5. modify grub to boot Android-x86
6. get grub source, edit menu.c and compile, reinstall grub

without 6. grub boot menu is not working. i tried to solve this problem by changing keyboard layouts, but maybe there is a bug in grub 2.02 because keyboard layouts can't be loaded.
you can compile grub2_2.02~beta2 yourself and modify grub-core/normal/menu.c to get the menu working. unmodified grub2_2.02~beta2 is attached to this post.

compile and install, everything is working fine. be careful and choose grub2_2.02~beta2, grub2.00 did not work for me.

how to compile and install grub:
- download source grub2_2.02~beta2.orig.zip and extract, modify menu.c
- cd grub2_2.02~beta2
- ./configure --prefix=/usr --with-platform=efi --target=x86_64
- make
- sudo make install
- sudo grub-install

problem is when reboot then w700 send b(volup) ,c(voldown) BUT when shutdown and start again. the w700 send up/down cursor keys ....


btw. cant get rEFInd to boot up android i allways get the msg "Invalid Loader File"

so i use gummiboot as main bootmenu -> grub2 to load android. and -> rEFInd to load Windows 8.1

now i can Hibernate Windows and play some game in Android and go back to Windows to resume my work feels like 2 Tablets now !!!


edit: attached my current bootconfig as sample. maybe you have to edit the configfile because your partitionnames/layout is diffrent

configs ->
E:\loader\entries\*.* (main bootmenu gummiboot)
E:\boot\grub\grub.cfg & E:\boot\grub\loopback.cfg (android)
E:\rEFInd_Windows\BOOT\refind.conf (windows)

Ok i modified my post above, everything is working now. when no USB-keyboard is connected vol+ and vol- sends GRUB_TERM_KEY_HOME and GRUB_TERM_KEY_END. when USB-keyboard is connected vol+ and vol- sends B and C now i can triple boot win8.1, ubuntu14.04 and android x86 4.4-r2 without USB-keyboard and with grub2 boot-manager.

thx. but i got an error ->
\boot\grub\x86_64-efi\normal.mod not found.

can you zip your entire boot\grub folder pls ?


btw. "END" is Volume down? and volume up cycles through the menu? because gummiboot does the opposite....

Not enough space?

Following you guide and when I hit install I get a not enough disk space error. I have like 4 partitions on my hard drive. It was upgraded from 8 to 8.1 by the previous owner. I'm guessing I am going to have to boot some partition software and resize windows. Any one else get this? Thanks in advance for replies.
