Top Known Defects
- Bluetooth not enabled on any device (due to bluedroid changes in MR1)
Starting with this release, Android-IA only supports booting on UEFI mode. To boot the installer, you must turn on UEFI boot through your BIOS menus. After downloading, please refer to the Quick Start for instructions on getting started with Android-IA.
- This has only been tested with Windows 8 and only with an EFI installation. We don't support dual booting with Legacy BIOS installations. The Windows 8 that comes installed on the Acer W700 is in EFI mode; there shouldn't be any Windows 8 slates shipping with a Legacy installation.
- Back up all your data! This is very important! Don't use this with any data you care about!
- If your device doesn't have any software on it, you should install Windows 8 first. You will need to delete all existing partitions in the Windows installer.
- The automatic installer has had a policy change; if it detects an EFI installation of Windows 8, it will not disturb it. Instead it will try to use unpartitioned space on the disk or replace an existing Android installation. Once you have dual boot set up, the automatic installer is suitable for updating the current installation if you don't want to use Fastboot or OTA updates.
- If the interactive installer detects a Windows 8 installation, it will ask you if you want to dual boot. If you say no, the entire disk will be erased and replaced with Android-IA. If the installer doesn't detect Windows 8, it was probably installed in Legacy mode.
- The interactive installer will let you resize Windows 8's data partition to make room. This uses the open source ntfsresize utility. After resizing the disk, the next time you boot into Windows it will go through a repair cycle; this is normal.
- The command line interface to the installer is pretty crude at the moment and will be undergoing some improvements in the weeks to come.
