http://www.easyuefi.com/wintousb/

- Window 8.1 32bit/64bit ISO

- a empty External HDD/Pendrive ( recommended 16 GB+)

- a 3.0 USB cable if available. Which smoothen/ boost up window operating speed.

DO AT YOUR OWN RISK.

2. Backups all your important data from your external HDD/ Pendrive. It will wipe all out/format for clean install.

4. Select your available disk. ( Notice, the selected partition will be wipe. As non-selected will not.)

You will notice format NTFS and FAT32.

 FAT32 is a format for pendrive ( usb flash drive), NTFS is a format for HDD commonly.

In my case, I select system partition on a 8GB partition and Boot partition on 16GB+.

So far, no problems.

5. Begin Installation.

6. After installation, close WinToUSB.

7. Insert your external HDD/pendrive in your new computer/ current computer.

Restart/Start your computer.

8. In booting screen ( Logo show screen), press F2/Del or F2+DEL commonly on every pc when the logo show up.

It will bring you up to booting selection.

Priorities:

Your ExternalHDD/Pendrive > HDD > DVDROM

Or

F8 in booting screen to select your external HDD/Pendrive

9. It then direct to your window installation screen, Good Luck.

Must know: 

1. Pendrive will slow down your operating speed. Hang, response slow, not responding, crash may occurred.

2. Do not use too long, is still a external HDD.

3. Everytime you plug into a new Computer, it will ask for installation.

4. Remember the USB port, this portable Window will only work on the USB port that you installed in.

5. It still can act as a storage to other computer.

Revert back to normal external HDD/ Pendrive.

1. Plug it in another computer.

2. Format the Disk, if installed on 2 different partition. Format on those two then.

3. All set back to Default, then format.

4. Done.

I do not own anything, I just simply share. 

You know what, this save me from the HDD that return back to WD.

Regarding on Software. Mind-blow troubles.

I bought this Computer : Customized CPU and Dell Monitor just about one month ago. It brought many many kind of problems due to my desired of Gaming and Installing software.
-Window 7 Ultimate 64-bit ( Currently )

- ASUS Mother board Z-87k

- 4GB normal RAM x 2

- 1TB SATA Blue

- Nvidia GTX 780

1. If I remebered, first one is on solving Window Update on pirated window ( I'm just a student with no monthly income, sorry for that.) I know it's risk to allow non-registered window to go update but I need it to install NET.Frameworks which allow to do many kind of things, ( I do not know much details.) especially for me is Games. 

- Solution: I visited a Microsoft website(forum) found out this problem on enable update to go online instead of 'Cross'.

#Troubleshoots problems name  #CMD configuration #Change Folders name in certain directory.

2. 32-bit --> 64-bit
This really.... one of the worst, I have to carry the whole CPU about 2km not included the road to the shops. N I guess my cpu is about 16kg.
- Solution: I have no idea about what 64-bit is for, but some softwares do need it. I not doing this on myself for format, becoz I never do before so I guess leave it to someone. ( You may try on your own, it's pretty easy with online guideline.) From the change, your one Local Disk will wipe out which contains the Window files only.

3. Unifi Malaysia with Wifi features, suck... In my case, I was sharing Wifi with other through 2 concrete walls.
-Solution: the only way I guess, upgrade a greater spread-signal/long-range router. ( No matter how strong your receiver is, router is the main concern.

4. Today, I was pissed. But, still I appreciated everyone for helps and great help people. Unlucky, I got my SATA WD hard disk corrupted ( bad sector) which contains a lot of softwares, games and datas, plus guidelines. They all just gone just in a sec, the shop IT/ Assistant refuse to help due to shortage on extra devices and bad pc spec. So, I only manage to recover a file only which is not either one of them.
- Solution: I don't know about hardware, sorry. I was under warranty so it went to factory and give me a new one now only in next 3 weeks.
I tried a lot of shit. If you happened to these problems, and not an expert, just give up. Buy a new one.
    - After logo boost very quick in SELECTION MODE
    - Boost in black screen after just a flash of Microsoft Corporation, and hang a few minutes
    - Boost into BLUE SCREEN with pattern ( flowers and watever) and mouse can move but nothing else.
    - Window Repair Failed several times. ( Keep ' Windows is loading files' everytime you reset your pc
    - Try CMD, rebuild booter but nothing happen.
    - Try USB/DVD repair disc/ window installation disc to repair but failed.
    - Try SAFE MODE boot, but same as blue screen with patterns.
    - System restore point won't work. Instead, show you a blue ring.
    -Window Memory Diagnose Tool detect no problems.
    - Whenever, you want try to do steps on Repairing, always hang very long, repair very long.(5 weeks at least.)
    - Try to reinstall/format, ' Setup is starting ' is loading LONG LIKE FLYING NYANCAT.

* Tips, You can backup/copy files,  in System Repair Mode after you can choose driver options. A box pop up and called you to choose. Instead, you can copy files there to the safe directory. ( If you can't see nothing even the free space size display, you might encounter the same problem with me. )

My college is starting soon and... 3 weeks pending time without that new computer. I hahaha....
Hope these would help.
