[Medium] How to format (Reinstall) computer yourself

[ 中文版后天推出 ]

When you noticed that your computer is running really slow, or when you decided to upgrade or downgrade the operating system, it is time to format.

Applicable to
Almost all operating systems with ISO image file (.iso)

Things required
- Operating System's ISO image file
- A disk, preferably DVD or a pen drive, preferably > 8GB
- A ISO burner (CD/DVD method) or Rufus (Pen drive method)
- Time: ~10 minutes (Burning) + ~1 hours (Format)

A. Burn ISO image file to a removable device
a. CD/DVD method
If you use Windows 8.1 or Windows 10, follow the (i), if you use Windows 8 or lower, follow the (ii)

(i) Use Windows's built in ISO mounting tool
Right-click the ISO image file you want to burn into the DVD and click Burn disk image. Insert the DVD and select the drive containing the DVD. Click burn after that and when it is finished go to B.

(ii) Use an ISO burner (We use Free ISO Burner)
Open and select your ISO image file, choose your disk drive and click on Burn to start. (You may adjust the Options yourself) Go to B when it is done.

b. Pen drive method
1. Download Rufus from here.
2. Run Rufus and plug in your pen drive. Select the pen drive name in Device and click on the CD icon. Choose the ISO image file. Click on Start. When it is done goto B.

B. Start formatting
NOTE : This section is too wide due to the amount of operating systems available, we will only briefly explain some keywords.

1. Reboot your computer and boot into BIOS menu.
NOTE : To boot into BIOS, repeatedly tap either F2, F12 or Del, these are the most common keys to open BIOS menu. If you are unable to boot into the BIOS, look at the first screen when your computer is booting up, there will be a menu telling you the key functions.
2. Look for device priority menu and change the removable device with the operating system as the first bootable device.
NOTE : Some keywords for this are 'Boot Sequence', 'Device Sequence', 'Boot Priority'.
3. Save and quit the BIOS, reboot your computer.
4. When there is a screen asking you to boot from CD/USB, tap Space (Or any other key).
5. You should be inside a installation screen. (This is Windows 2000 setup, of course it looks ugly and not user-friendly, but Windows such as Windows 7 or 10 is more user-friendlier and easier to install)

6. Follow the instructions, these are the things you need to know:












(i) Upgrade or Advanced Settings
- Newer Windows NT, only show when you have pre-existed operating system in your computer.
If you don't want to lose anything and just want to upgrade, choose Upgrade. Else, choose Advanced Settings.

(ii) Partition Management
- Almost all operating systems
Choose Advanced Settings (In Windows) or when installing most of the Linux operating systems, it will ask you where to install the operating system. It will be better if you know which partition to install. If you choose a partition, the operating system will install inside the partition you choose and push the older operating system into a folder if exist. To wipe out the whole partition you can format that.

(ii) Serial key
- Almost all Windows operating systems
Some of them is compulsory to enter a valid key, while some operating systems you can skip the procedure and have a 30 days trial before you need to reinstall the computer again.

7. Wait for everything. The screen might flash and computer will restart during the installation.

8. When you see a setup screen, follow the setup and you will eventually finish the whole format stuffs.

Isn't it simple? You shouldn't waste RM100 just to tell the computer shop to help you now.

(Be warned, buying Windows operating system cost more than RM100, but you can use it forever. As an alternative, go Linux, if you like terminal.)

[Medium] Create a Minecraft server

 zh  <-- 萌萌哒！换去华语！
 OLD  This belongs to older version <: 5 / 2015 :>

Want to take one step forward? Make a server!

NOTE 1 : This tutorial is about creating Vanilla server, not Bukkit.
NOTE 2 : This tutorial is about creating server on your computer (your computer as the host), not using a online server.
NOTE 3: This is not recommended for computer with less than 2GB of RAM, a very slow processor , or upload speed less than that of 1 Mbps. If any of this isn't satisfied, your server experience would be poor.

Prerequisites
- Latest Minecraft Server files
- Knowledge of your router
- Hamachi (No Port Forwarding needed) or Access to router settings (Port Forwarding needed)
- At least Pentium or similar, 4 GB of RAM, ~2 GB HDD
- Fast upload and download speed (Upload is generally more important here)

Download required files
Go to the official Minecraft download page to download the latest server files.

Install the server
1. Create a folder anywhere in your computer, that is folder where your server files goes.

2. Drop the .exe or .jar server files into the folder, then double click the server file. The folder should now look like this.

3. Open the eula.txt ,change the eula=false to eula=true. Save the text file.

4. Relaunch the server file again. This time the folder should look like this.

Configuring the server settings
Close the server console, then open the server.properties using Notepad.

Changing these is optional (but mandatory if you have friend using cracked launcher/account), you can check out what the settings does here.

Before we continue...
These tutorial below is essential for external network connectivity. If you want to play the server in LAN only, you can start the server by launching the server executable directly.

a) HamachiPros : No port forward is needed, uses P2P so it can be faster.
Cons : Have limited peers (Free version), other player also need to install the client in order to get into your server.

b) Port ForwardingPros : Unlike Hamachi, you don't need to let other player to install anything to connect.
Cons : Need access to router, will mess up your network if not done properly, susceptible to DDoS, but it will generally not happen unless your server grew big.

1. Identify your computer IP Address and Router IP.
Open command prompt and type in ipconfig ,look at the IPv4 Address and Default Gateway. Remember these as you need it later.

2. Use your browser to access the router settings.
Type in the IP Address of your Default Gateway into browser address bar.

3. Login to your router settings.
If you don't know the username or password you might need to check your router manual or ask your ISP for this. Check this tutorial to see how to find out your router password.

4. Look for the setting.
Look for either Port Forward / NAT / Virtual Server in your router settings. This usually located in a menu called Advanced Settings.

5. Setup the port forwarding setting.
For the Application name, type in Minecraft Server, For the Start / End port number, type in 25565 (Need to be changed according to your server setting) and for the Local IP Address, type in your IPv4 Address. Then save the settings.

OPTIONAL : You may need to consider use a static IP for your computer so it won't change every time you restart your router or computer. This is useful as you need to restart router everyday and you have plenty of connected devices.

Finished
After all the hassle, your simple server is done! Go find your External IP address including the port and give it to your friends so they can join the fun! 

[中等] 设置一个原版当个创世神伺服器

 en  <-- Greetings! Click here for English!

想要证明你是我的世界高手？弄一个伺服器吧！

注意 1 ：这个是弄一个原版伺服器，不是插件伺服器。
注意 2 ：这个教学是把伺服器装在你的电脑，不是叫其他伺服器帮你开。
注意 3 ：不建议任何少过2 GB RAM的电脑，很慢的处理器或者少过1 Mbps上传速度的网速。任何这三点不达标，你的伺服器会运行很慢。

材料
- 最新的我的世界伺服器文件
- 基本路由器的知识
- Hamachi (不需要Port Forward)或能进入路由器更改设置(需要Port Forward)
- 好的处理器，4 GB RAM，大约有2 GB硬盘空间
- 很快的上传和下载速度(上传在这里会比较重要)

下载伺服器文件
去我的世界官网下载最新的伺服器文件

安装伺服器
1. 在桌面弄一个新的文件夹。在里面放置你的伺服器文件。

2. 放置你的.exe或.jar的伺服器文件在那个文件夹，再双击你的伺服器文件。现在你的文件夹会有以下的文件。

3. 打开eula.txt，更改eula=false成eula=true。保存文件。

4. 重开你的伺服器文件。现在文件夹会有这些新文件。

设置你的伺服器
关掉伺服器的控制台，然后用Notepad打开server.properties。

你没必要去更改这些设置（除非你有朋友是用盗版来玩），你可以在这里查看这些设置是做什么的。

继续之前...
以下的教学是给公开性加入。如果你只想在同一个网络里玩，你可以打开伺服器并开始玩了。

a) Hamachi
好处：不需要Port Forward，利用p2p的技术会加快速度
坏处：有限制（免费版），其他玩家也需要安装Hamachi来玩。

b) Port Forwarding
好处：玩家不需要安装任何东西。
坏处：需要进入你的路由器来更改设置，如果弄错会导致上不到网，会遭遇DDoS攻击（如果你的伺服器是非常的多人玩）

1.检查你的电脑IP和路由器IP。
打开Command Prompt然后输入ipconfig，寻找IPv4 Address和Default Gateway。记下后面的IP，等下需要用到。

2.用你的浏览器进入路由器设置。
在你的浏览器输入Default Gateway的IP Address。

3. 登入你的路由器
如果你不懂你的用户名字或密码，你可能需要看看你的路由器的教学本或者问你的网络公司。你可以用这里的教学来找出如何得到密码。

4. 寻找设置

去找 Port Forward / NAT / Virtual Server 的设置，通常他们是在Advanced Settings里面。

5. 设置Port Forward

Application Name输入Minecraft Server。Start / End port number 输入 25565 (根据你的伺服器)，最后Local IP Address输入你的IPv4 Address。按Save来保存设置。

建议：你可能需要设置一个固定的电脑IP Address所以每次你重启电脑或路由器不会换掉。这个非常适合那些常常重启你的路由器的玩家。

完成

经过许多的设置后，你的伺服器也完成了。去找你的External IP Address，包括Port，然后给你的朋友好让他们加入你的伺服器！
