not sure where to put new topic - can only post in certain parts of forum?

Problems:

 

1. Just joined imgburn forums because I am having trouble making an ISO from my retail windows 7 professional disk

 

1. My retail windows disk is in my drive.

 

2. normally to create an iso I goto EZ mode picker and choose create image from disk and select the destination > create. done.

 

3. However this time when I extracted the ISO with 7zip i did not get all the folders as is on the dvd like I was expecting

 

figure 1 is the contents of my retail dvd

 

figure 2 is what I see after extracting the ISO I created using imgburn (see step 2 above)

 

I was expecting to see figure 1 after extracting?

 

Therefore, did imgburn create a UDF image instead? how do I get it to create an ISO which shows all the folders like in figure 1 when I extract it.

 

Sorry I dont know anything about UDF at all

 

 

2. tried to create a new topic or post in the forums but this is the only place I can seem to post?

 

Not sure why I cant create new topics how else can I ask for help?

 

Any Help Much Appreciated Thank you.

You can create new topics in forum apart from the top 5 under the 'General' heading.

 

ImgBurn doesn't 'create' a UDF image, it just reads exactly what's on the disc, sector by sector.

 

From what I can see (the pics aren't showing up), there's no issue with ImgBurn here. Whatever you're using to extract the files from the ISO file (7zip) is just extracting from the wrong file system.

 

The newer OS discs don't use the ISO9660 file system, they use the UDF one. So if your extraction program only extracts what's listed in the ISO9660 file system, all you're going to get is a file saying you need to use an OS that can read UDF. Use a program that extracts from the UDF file system and you'll be fine. Of course it's pointless extracting anything from the ISO when you have the original disc and could just copy+paste the files in Explorer! You could even mount the ISO in a virtual drive program (Something like Virtual CloneDrive) and copy+paste the files that way. The OS would have no problem picking up the UDF file system rather than the rubbish old ISO9660 one.

 

Is your version of 7zip up to date? Maybe they've fixed this problem in a newer (beta?) release?

Thanks for the advise, so if ISO is so out of date, what are some of the advantages of this newer UDF format?

 

I've also just checked and my 7zip is the latest version, 9.20

Wondering what the second one is with just boot? I was expecting it to look like the first one?

The initial spec of ISO9660 only allowed for file names in the old 8.3 format (XXXXXXXX.YYY) and you could only use 'A' to 'Z', '0' to '9' and '_' characters in the names. There is no real support for large files either so you're limited to stuff under 4GB in size.

 

UDF has no such limitations and add supports for Unicode characters etc.

 

UDF isn't new though, it has been around for ages now and is used on all DVD / BD Video discs.

 

I don't really understand why 7zip chose to extract from the ISO9660 file system rather than the superior UDF one, you'd have to take that up with its author.

 

EDIT: I just installed the 9.20 version of 7zip and it extracts my Windows 7 images ok. Weird.

Thanks for testing, and your description of the UDF file system. I may unistall 7zip and see if reinstalling fixes the problem. Otherwise I will try creating new images of my installation disks and see if that helps. I will post back when I'm done. Thanks again.
