Windows 10 upgrade stop at 24%

It's so painful to upgrade windows 7/8.1 to Windows 10 when it stuck upgrading process at 24% during copying files. The upgrade was establishing using iso media.
After dozens of try without luck, I solved the problem by running setup.exe in iso media with opsions  /auto:upgrade /noauto exit /performED.

> Setup /auto:upgrade /noauto exit /performED

Unfortunelty, you have to perform this upgrade online.

How to fix grub-efi Debian 8 after windows 10 upgrade

After and during upgrading your Windows (with EFI/GPT) into Windows 10, grub-efi will broken.
----------------------------
Symtom:
----------------------------

grub rescue>

1. Find linux
grub rescue> ls
(hd0) (hd0,gpt7) (hd0,gpt6) (hd0,gpt5) (hd0,gpt4) (hd0,gpt3) (hd0,gpt2) (hd0,gpt1) (hd1)
grub rescue> ls (hd0,gpt6)
(hd0,gpt6): Filesystem is unknown.
grub rescue> ls (hd0,gpt7)
(hd0,gpt7): Filesystem is ext2.
2. It is mark as (hd0,gpt7) as ext2. We search boot directory
grub rescue> ls (hd0,gpt7)/boot
./ ../ ...... /grub ......
3. It is contains folder boot. Good! We set root and prefix for normal boot
grub rescue> set root=(hd0,gpt7)
grub rescue> set prefix=(hd0,gpt7)/boot/grub
grub rescue> insmod normal
grub rescue> normal
4. Finish your Windows installation or upgrade. You may need to repeat step no. 3, everytime Windows ask you to restart your computer.

apt-get install --reinstall grub-efi-amd64
6. Create directory /boot/efi
# mkdir /boot/efi

Android Development Tools: Which Packages to Install


As a minimum when setting up the Android SDK, you should download the latest tools and Android platform:
  1. Open the Tools directory and select:
    • Android SDK Tools
    • Android SDK Platform-tools
    • Android SDK Build-tools (highest version)
  2. Open the first Android X.X folder (the latest version) and select:
    • SDK Platform
    • A system image for the emulator, such as
      ARM EABI v7a System Image

The Android Support Library provides an extended set of APIs that are compatible with most versions of Android.
Open the Extras directory and select:
  • Android Support Repository
  • Android Support Library

To develop with Google APIs, you need the Google Play services package:
Open the Extras directory and select:
  • Google Repository
  • Google Play services
Note: Google Play services APIs are not available on all Android-powered devices, but are available on all devices with Google Play Store. To use these APIs in the Android emulator, you must also install the the Google APIs system image from the latest Android X.X directory in the SDK Manager.
