How to make bootable removable device like USB disk

Asked By anne robinson 210 points N/A Posted on - 06/02/2011

I am always having this problem of losing my operating system. My computer have a usual crashing sickness. Maybe its because I am very careless when it comes to downloading Software's, and other particulars with regards to computer. And also my kids usually play games online and they accidentally hit something on my machine that causes it to suddenly stop working. Oftentimes, I payed for an expert technician to fix the problem.

I am using an ASUS Essentio CG8350-06 Desktop, Processor Family Intel Core i7, with 8Gb of RAM and storage capacity of 1000Gb, Graphics Card Intel HD Graphics 2000 with Windows 7 Home Premium. This desktop is really for gaming purpose and just for some social networking websites. 

What I want to know is how can I make a bootable disk for me to use when my computer crashes again? It was because most of the time, when it crash, the computer cannot boot from its installation or recovery disk.  And I want to fix it by myself.

I want to make a ghost program and a bootable USB or pen drive. Can someone give me a step by step procedure?

I tried making a bootable USB using an 8Gb USB stick, but I did not succeeded. I am having problems with the CD BOOT command.(or maybe I am not just a PRO).

I could not locate the correct drive for cd boot command where E: is the drive for my CD/DVD ROM, I don't know but I am having an error that the computer could not find Drive E or something like that.

If you know what I mean please reply and I will really, really appreciate it. Thank you.

How to make bootable removable device like USB disk

Hello Anne,

To make a bootable CD so that you can use it to load the OS when yours system crashes, you will need the following items:

• An original copy of windows CD/DVD or an ISO.
• A copy of Boot file that you can download from the internet which you can download from the following: (bootfiles-from-tacktech-website.zip ~1.34KB). Once the boot files have downloaded extract them to COSBoot folder
• You will also need a minimum of 5 GB hard disk space to hold the data from the CDs/DVDs

Once you have all that set, you will create a folder called OS on your hard drive which should be C;, then create there a two sub-folder called BOOT, and ROOT.
After that you will need to copy the entire Windows OS CD into folder that you labeled  ROOT, and then click on the ISO tab. Done with that, do the following:

• Set File name Length for the OS.
• Set the Format to Mode 1.
• Set Character Set to ISO 9660 (standard ISO CD-ROM).
• Check all Relax ISO Restrictions for the OS that you are making bootable.

You will have successfully creates a bootable CD, and you can use it any time your computer crashes.
