Windows 7 ISO boot - code 5 - boot sector might be incorrect

I wonder if the people at Microsoft who created the downloadable ISO for
Windows 7 know that the boot sector doesn't follow the ISO 9660 spec.

....which says, if you get a Code 5 when booting from a DVD, do the
following (the post mentions Vista, but I am getting this with the
Windows 7 RC):

Download Vista SP1/2008 x64 ISO from MSDN, orgrab your CD [or Windows 7]
Create 3 folders c:\efi-iso c:\efi-exe c:\efi-dvd
Download oscdimg.exe from here into c:\efi-exe
Extract iso using 7Zip or WinRAR (Or copy the contents of the DVD) into
c:\efi-dvd
Start up a command prompt (Start -> Run -> cmd)
Type: cd c:\efi-exe
Type: oscdimg -n -m -bc:\efi-dvd\boot\etfsboot.com c:\efi-dvd c:\efi-iso
\server2008dvd.iso




It's weird that the official Windows 7 RC downloadable ISO from Microsoft
*seems* to have a boot sector that doesn't follow the ISO 9660
specification. I could be wrong, but...

Has anyone else been flummoxed by a Code 5 booting Windows 7 RC from a
real, internally attached DVD drive? In my case, I downloaded the ISO
twice and tried two different locally connected IDE DVD drives, then
found the information above.

Perhaps Microsoft can check this out and possibly fix the RC... or fix
the official build eventually!!!!

Thanks.

I had no problems with the Win7 ISO file from MS, but I was loading it
from the ISO file as a virtual dvd drive to a virtual machine.

The RC download is an ISO file, which you'll need to burn onto a blank
disc before you can install it. To do that, you'll need to use software
designed for burning ISO files.

In addition to commercial ISO burning software, there are free programs
such as ISOBuster and Active ISO Burner. To find one, go to a site such
as Download.com or Tucows and search for "ISO," "DVD," and "burn".

Follow the instructions that came with your program to create a Windows
7 RC installation disc.

If you can only understand what you have posted then you would not have posted the
completely misunderstood information on your end.
The only possible thing that I can say to you is to grab the bull by the horn and
learn and learn and learn.

You need to convert the downloaded ISO file of W7 RC1 to a bootable DVD format.

Also what you posted has nothing at all to do with the ISO format of W7 RC1

Use something like ISO Buster,Nero or similar to make a bootable media from the
downloaded ISO so as you can install it.

Hello,
Download, Iso-burner.exe a 646kilobit free running application, does not
need to install.
Place this in a folder (c:\download) or any other folder.
Place the .iso file in the same folder, double click the .exe application.
This will locate the iso file and the DVD burner, have a blank DVD disc in
the
burner.
Click start, when the application stops and opens the DVD drive, there will
be a bootable Windows 7 RC disc, ready to install.

A free application, use Google to locate.
Take care.
Beamish.

Hello Again,
Slight error in the above information.
First the download site.
http://www.ntfs.com/iso-burning.htm
Second unless you want to install make sure you download the .exe not the
set-up file.
The set-up file needs to be installed, the .exe does not.
Size is KB not kb.
take care.
beamish.
 
actually david walker does know what he's talking about, and he does know how to burn an iso.

if you google "windows 7 cannot boot from cd code 5" you'll see waht i mean.

many people with older pc has that problem, including me :)

i'm here as a result of googling.

and i signed up just to thank david for his effort to help ppl with this problem.

i didn't use david's solution as there is another solution which i personally prefered, the boot to vista command prompt solution.

anyway, thanks again david.

edit: a cut and paste job from another forum....

You need Vista install DVD. Boot Vista Installation, choose Language press next and than press "Repair my computer". On next window u will have few options, choose "command promt". Remove Vista DVD and insert Windows 7 Install DVD. Navigate to DVD (for example d: or e:, depends on your drives setting, than go to folder sources (type "cd sources" ), and type "setup". Installation will start shortly. Now just follow instructions

Yes, correct. But you can create a bootable disk by you own. Take a ISO 9660 conform boot sector from other bootable disk (e.g. Vista) and merge it into the Windows 7 installation disk. See here.
