Windows 7: Windows 7 installation CD format problem UDF format

Windows 7 installation CD format problem UDF format

Hey guys, I downloaded Windows RC ISO file, there's a readme file that reads "This disc contains a "UDF" file system and requires an operating system that supports the ISO-13346 "UDF" file system specification."

What exactly does UDF mean here? Plus, that ISO has a size of over 2GB, but when I open it using tools like ISO buster and UltraISO, it is shown to have a size of only several kBs. Why is that?

I ventured to burn that ISO file onto a blank DVD using Alcohol 120% ,but when I tried to install it, I was promted no bootable record was found on the DVD.

Can anyone help ?

1) When you DL an ISO, you don't need to open it up with UltraISO or any thing else. If you're already running Windows 7 it has a native ISO image to disc burner. If you're using Vista / XP, grab Alex Feinman's ISO Recorder v3

2) If you want to use a third party tool ,that's fine, but use it on a virgin DL - IOW, ***DON'T*** play with it in UltraISO or anything like that - DL it and burn it to disc.

3) If you prefer to boot off of USB and install it, follow our tutorial: USB Windows 7 Installation Key Drive - Create

I'm just not understanding what you are trying to say here ..

I downloaded the Win 7 rar files under an "academic download" program .. Un-rar'd them to an iso and burn the iso with Nero .. very straightforward
The resulting disk cannot be read under Windows 7 build 7100 RC because of this UDF stuff problem ... what next ?
heck as a test, I did do exactly the same with the Dutch version and that is readable without a problem (but it does not install because of conflicting system language issues)
Plse elaborate ? Did MS muck up this one?
TIA

Zipstone,

I've got the same prob!
When I look at the (100% official) installation dvd in explorer (win 7 rc), I sometimes see the content & at other moments just the text file with the UDF-error.

Has anyone found a solution yet??

Thx in advance!

I have a similiar problem and I do not know how I did this. I was transferring my pictures from camera card to a CD. I burn the pictures onto the CD. I tried to burn 2 more and it said CD is corrupt. The CD is now a UDF file. Now I cannot see those pictures that I transferred and it is getting me upset. I went to Microsoft and it said to download a Hotfix, but to make sure that it is the correct on, or just wait for the next version of Service Pack #2. I am kind of naive to all this. Please help me so that I can see my pictures. I have also read that Windows 7 does not support UDF files. So how did my CD become one in the first place. Please help.
