Well okay, so thanks for all your help. Let's consider this case as closed. Regards Horaxon

Well, nice. Sounds familiar, I remember having used Bart's Boot CD some long time ago. ;-) Feels like a very distant past... I also remember some HP USB tool, think I've seen that one before. This was officially distributed by HP, if I remember correctly. I wish I had the link from back then. Maybe one of you guys here still have that link? I searched some other forums, some folks mentioned this WinUSB Maker tool (http://www.joshcellsoftwares.com/2012/06/WinUSBMaker.html) Does anyone know it, is it good?

But what about the 1.44 MB limitation of a floppy disc image? Or can I put the flasher util and the BIOS file (which are of course too large) on some kind of second partition on the disc? My ODD is a Pioneer BDR-207EBK. The bootable .ISO image file from Memtest86+ (www.memtest.org) seems to work. Can't I somehow use that image file? On the other hand, when I tried the update via USB stick I used the "F7" method (thats how Intel calls it), which is just the BIOS file on a stick, so nothing bootable or DOS. So maybe I should try it with a DOS bootable USB stick. But I can't create one with the functionality integrated into Windows, right? Since you have used that method before, what would you recommend? A certain software tool for creating said USB stick? Regards Horaxon

Well, my plan was using a bootable optical medium because the last attempt with an USB stick failed. I think its a bit astonishing that a bootable DVD with a DOS environment seems to be a somewhat exotic request ;-) Why are this kind of disc image files so rare?

I somehow knew this wouldn't be that easy But what is "etfsboot.com" good for then? Does it always automatically start Windows Setup? My mainboad is a intel DZ77GA-70K. So far only one out of two BIOS update procedures via USB stick has been successfull, so I thought that I use a DVD next time, just to be sure. The description of the BIOS update says: Iflash BIOS Update / Integrator Toolkit BIOS Files [GAZ7711H.86A.0053.BI.ZIP] - A DOS-based utility to update the BIOS regardless of operating system. It requires a CD or a USB flash device. This download also provides the necessary files for Intel® Integrator Toolkit. Support and FAQs for Intel® Integrator Toolkit are (For Reference, taken from here.) But this ZIP file unfortunately does not contain a bootable image :-) So what do I have to do now? Regards Horaxon

Well, first of all, Hello everyone! The Guide (How to create a Windows Vista / 7 installation disc (bootable) using ImgBurn) is pretty straightforward and self-explanatory, so my compliment on that. My question: Can I use this method to create a bootable DVD for using a BIOS flash utility. The utility says it is DOS based, but I don't believe that is the issue here. I suppose a bootable DVD created this way somehow automatically starts a "setup.exe" for the Windows Installation. So I need to modify this autorun behaviour in order to get a command prompt. The technical "difficulty" of a bootable disc is accessing the optical disc drive using a driver included on the medium, I would guess. So I believe this should be possible... Kind Regards Horaxon
