I am currently running Windows 7 (Build 7201, 32-bit). I am facing a problem while performing a fresh install of Windows 7 RTM (64 bit) using an USB drive. To make the flash drive bootable, I need to run the bootsect utility. And it seems that you cannot run the 64-bit version of bootsect from inside a 32-bit host OS.

Any help would be appreciated.

I do not believe you can create a 64 bit install from a 32 bit version of the OS (or vice~versa, for that matter). There is a way around it using (a trial version of...) UltraISO.

Thanks a lot.

The method #2 described on your link is exactly what I was trying to follow, and if you notice, they have clearly mentioned about the issue I am facing. :) 

Let me try method #1, and hope that it works!

Method #1 worked!

@Scotteq: Thanks a lot!

@silversurfernhs: This link describes the method #2 mentioned by me above. It does not work across x86 and x64 (as in we cannot create a x64 windows usb while working in x86 windows).
