Windows 7: Cannot format DVD - R (want to create boot disc)

Cannot format DVD - R (want to create boot disc)

I want to create a boot disc for Windows 7, I copied all the contents of original Windows 7 CD to my recently brought clean DVD-R disc with NERO. It just worked once on my friends computer and when I tried it second time, it failed to boot from DVD-R. I had set the BIOS settings correctly in boot menu. It tried to boot from DVD but it didn't find any boot info.
(When I insert original windows 7 CD it boots correctly)

Then I deleted all the folders in DVD and thought I would paste them again later, all the folders got deleted leaving behind used space. When I open it, it shows the DVD empty but almost 1/2 of the space is used up and I cannot paste my Windows 7 setup in it again.

I tried formatting it again and again but it still shows 50-60% used space.

Is there some way to completely erase my DVD-R?

Welcome to Seven Forums.

DVD-R discs are write-once only.

Even if you had used packet-writing, deleting files and folders does not recover the space occupied by these. These are simply marked as deleted.

You are entitled to make one copy of your genuine Windows 7 Media as a back-up.

Create an ISO image of your original DVD media using Windows 7 native image burner and then write it to a DVD-R media using the same native image burner.

If you are new to CD/DVD writing, I recommend that you use a DVD-RW first and try. Once you have done the project successfully, you may then use a DVD-R to make your copy of Windows 7 Media.

You may then erase your DVD-RW and use it for any other temporary storage purposes.

I don't understand what you are trying to do. A Windows 7 disc is bootable. Why do you need to create another?

It is your right and a very good practice to make a copy of a disc that cost so much. But put it in a different safe location.

The Windows 7 USB DVD download tool can make a bootable USB Thumbdrive or DVD from an ISO file for you. It can be picky about the ISO file though, so depending on where you got it or how you created it it might reject it.

The OP has never once indicated that they were making a copy of a Windows 7 disc. It says they are trying to "create a boot disc for windows 7" which tells us nothing. A boot disc has nothing to do with an installation disc. I asked the OP to clarify and got no response.
