how to copy dvd with windows?

Posted on

QUESTION :

I have Windows DVD and remote HP server
I need to install Windows via ILO.
I can not do this via internet because server internet connection is very slow. So I should create Windows DVD image and ask admins to burn it and to connect to server via external DVD-ROM. I’ve created *iso image of Windows DVD but now I can not write it on standard DVD because image is LARGER than a DVD. How is that possible? Is it kind of protection?

ANSWER :

Standard DVDs have a 4.7GB file size limit, dual layer disks have twice that (roughly).

If Nero is saying the image is too big for the disk, it’s too big. You either need a bigger disk, or to split the files up onto two disks.

There are four common different DVD sizes. If the source DVD has more capacity than the destination DVD, you won’t be able to perform a one-to-one copy.

From DVD Sizes – About.com, Digital Video Recording:

  • DVD-5 holds 4.7 GB and is supported by the DVD+R/RW and DVD-R/RW formats. It is also known as Single-Sided Single Layer.

  • DVD-10 holds 8.75 GB and is supported by the DVD+R/RW and DVD-R/RW formats. It is also known as Double-Sided Single Layer.

  • DVD-9 holds 8.5 GB and is supported by the DVD+R and DVD-R formats. It is also known as Single-Sided Double Layer (sometimes called Dual Layer). The official names are DVD-R DL and DVD+R DL

  • DVD-18 holds 15.9 GB and is supported by the DVD+R format. It is also known as Double-Sided Double Layer (or Double-Sided Dual Layer).

(formatting mine)

Be aware that GB means gigabyte (1 billion bytes). Windows (wrongfully) uses GB for gibibytes (correct: GiB). As a result, a DVD-5 holds 4.37 GiB.

If it says it won’t fit on the disk, then it won’t fit on the disk. But you could try installing windows using a USB drive.
