OK... Finally solved the problem during my winter break... took almost 1.5 months Actually we users are creating the problem... Bootcamp is OK... our late 2013 Mac is OK... but Apple is't as it's not giving us the solution Now let me clear concisely what actually occurs behind the problem.
When you open bootcamp to install Windows, you get a popup window. Then you click continue... then you choose the options among the three which suits to your intention. Then if you chose to create a installation disk or/and download the Windows Support Software, bootcamp does so. Then the nextPROBLEMETIC STEP comes! Yes! you got it! This step creates the actual problem: Partitioning the hard disk for installing Windows. Before bootcamp starts partitioning, a simple POPUP WINDOW will inform you whether you will get the f*cking "Windows could not update the computer's boot configuration. Installation cannot proceed" message or not during your windows installation! Andddd... the popup window is here:
Soooo... super duper simple fact: if you don't get this popup window, you're going to get that error. Because this HELPER TOOL will simulate proper environment for installing Windows in your Mac
Now be sure:
1. You just have one partion in your Hard Disk before partitioning it into two for installing Windows
2. This PARTITIONING SHOULD ONLY BE DONE BY BOOTCAMP if you want your Windows in EFI mode. The way jarvil told us is for BIOS mode. I'm not going to explain here what is EFI and what is BIOS. Simply keep in mind that EFI is latest, better and faster for booting your Windows
That's it guys! If you don't get that popup window, follow the instructions:
1. Turn your hard disk into a single partition by using Bootcamp/Disk Utility. Bootcamp is recommended
2. Take a flash drive, format it, and then open Bootcamp
3. Choose all the three options:
Create a Windows 7 or later vertion install disk
Download the latest Windows Support software from Apple
Install or remove Windows 7 or later version
Yes! We are going to create a new installation disk...
4. I know you are clever enough to guess what should you do now! Just enter your password when you get THAT SPECIAL POPUP WINDOW!Then Mac will restart after partitioning your hard disk!
5. Do noting untill the windows installation window comes
6. Go forward pressing Next, putting serial, and accepting the agreement that we never read
7. Select advanced installation... I mean the second option
8. Now find the partition named BOOTCAMP
9. Select it and Format it!
10. Click Next
You are done! Your Mac will install windows without any problem or error message After installation, if you find that your drivers aren't working, go to the installation disk and open the folder named BOOT CAMP. Open the exe named Setup... Install the drivers and restart after completion... Your Mac now owns Windows in EFI mode like mine!
That's all I have known killing my winter break! Thanks everyone! Take care!
