Re-install Windows 10 on Asus

Asus R457UV

re-installer Windows via clé USB.  (disque dur remplacé par exemple). Besoin du user bios admin. Si un user admin bios a deja ete installé et que l'on ne se souvient pas du mot de passe, il faut reprogrammer l"EEPROM sur la carte mere sur ce modele.

https://www.forum-des-portables-asus.fr/forums/resources/changement-et-ou-reprogrammation-de-leeprom.208/

La clé Windows est en dur sur la carte mere Asus. Elle n'est plus fournie ni à l'utilisateur ni au constructeur. C'est la politique de Windows pour éviter les fraudes.


Télécharger l’image ISO de Windows 10 depuis le lien ci-dessous mais il faut choisir la langue, la version et l’architecture qui correspondent au système préinstallé, c’est-à-dire, si vous possédez un Windows 10 Home 64bits français, il faut sélectionner Français au niveau du champ « langue », Windows 10 Home dans le champ « Version » et 64 bits dans « architecture »
1. Bios / Security / Secure Boot Control = Disabled
2. Bios / Boot / Fast Boot = Disabled
3. Bios / Boot / Launch CSM = Enabled
4. F10 + Yes
5. Bios / Boot / Boot Option Priority = Clé USB
6. F10 + Yes

https://www.asus.com/in/support/FAQ/1013017/

[concernant ce paragraphe, je n'ai pas pu remettre le BIOS comme avant. Je suis resté en Bios "CSM enabled". Quand je passe en CSM disabled, le disque dur n'est plus detecté]
L'ordinateur va booter sur la clé USB. Une fois l'installation du système (Windows 10) est terminée, Il faut revenir dans le BIOS et remettre toutes les options changées plus haut comme au début et surtout Bios / Boot / Boot Option Priority = Windows Boot manager et F10 + Yes, l'ordinateur va démarrer sur le système.
A la fin de l'installation, le système va récupérer automatiquement la clé lors de la première connexion internet pour la récupération des différentes mises à jour Windows.

Windows 10 famille 64 bits

Multiple git accounts

Using multiple ssh keys for multiple gits:
https://gist.github.com/jexchan/2351996
Add the ssh keys on github

Some possible "git config --list" options are "--local" and "--global"
If you don't specify --global, it takes the local config by default.

To display the actual  “git config” do:
git config --list
git config user.name
git config user.email

Before you commit, you need to be sure you are using the correct one.
You can set it by doing:
git config user.name "abc"
git config user.email "abc@abc.com"

The local config will be saved in .git/config
The global config is saved in ~/.gitconfig

"url" must be a git@something  in .git/config, should not be https. If it is https, use:
“git remote set-url origin git@github.com:me/gg-linux.git”
It will change your .git/config

_______ git clone
to display default config:
  • git config --global --list
Even if the keys are on github, you may want to use a specific name/email
  • You can use
    • git clone XX -c user.name=toto -c user.email=toto@toto.com (this will set .git/config)
  • or
    • git config --global user.name "xxx"
    • git config --global user.mail "xxx"
    • git clone git@github.com:youruser/myj-gh     (need ssh keys)
______________ Just using ~/.ssh$ more config 

Host *.internal 10.*
identityfile ~/.ssh/id_rsa

Host *github.com
identityfile ~/.ssh/id_rsa_github
