I recorded a quick video tutorial on how to do this - some of you may find it interesting and/or useful. :)

I received a bootable USB disk containing Windows 8.1 from school today and I wanted to turn it into a bootable ISO. After a bit of Googling, I found out how and here is a quick video explaining.

The portable version of ImgBurn which I used can be downloaded from Softpedia and the download should start automatically.

The formula for finding the number of boot sectors to write is:

no. of sectors to write = size of etfsboot.com in bytes / 512.

Eg, if you have a 2KB etfsboot.com file, then that is 2048 bytes / 512 = 4 or if you have a 4KB etfsboot.com file, that's 4096 bytes / 512 = 8


I hope some of you find this useful. May or may not come handy in the future. :good:
 
Thanks. Yeah when I was Googling I realised that there were loads of tutorials telling you how to make a bootable USB disk from an ISO, but only one or two good tutorials for the reverse.

I recommend you use the portable version of ImgBurn. When I tried to download ImgBurn directly from their website, Google Chrome simply wouldn't download it (and nor would Internet Explorer). After some reading, I found out that they're now bundling all kinds of potentially unwanted software with the ImgBurn installer which is a real shame. This portable version is from 2009 but at least it doesn't have all the crap that the latest versions do and it still does the job. :good:
 
I have imgBurn installed in two computers and you just click custom install and untick all the crap.

I just discovered that you can use universal extractor and extract the imgBurn.exe file and you will find a setup file. But I guess this would be the same as portable mode.

Click to expand...

I can't even download the setup file any more. When I try on Chrome it doesn't actually download it and when I try on IE it says it can't download it. But I can download other stuff...

Portable version seems to be working well though. :)
