Dumb question - having trouble installing centos

[JoshBock]

I'm trying to learn centos - I have an extra laptop laying around with Windows 7 that I'm not using, so I figured i'd put it on there. Here is my order of operations...

1. I downloaded Centos 7 DVD iso
2. Burned CentOS 7 iso dvd to DVD
3. Went to bios changed boot order to CD/DVD drive 1st then hard drive
4. Booted computer up with DVD in the cd trey

At this point, it tries to read the DVD, then moves right on to booting windows. Any idea what I'm doing wrong? I'm pretty new to the tech world, but relatively good at following directions - so bear with me. Any help or ideas would be appreciated.

Thanks

Look at the contents of the DVD with Windows explorer and if you see lots of files and directories then you probably burnt it correctly but perhaps your media is bad. If you just see one .iso file then you burnt it wrong and need to do it again, this time burning it as an image not as a file.

Which DVD iso?

[JoshBock]

When I view the dvd in windows explorer, it's one .iso file. that's all I saw when I downloaded it from the "dvd iso." And burned it as such. is there supposed to be more files than just the iso file that I download? and how do I get them? Sorry for being so computer illiterate here

[JoshBock]

and it's the 7.0 dvd iso that you find on the mirrors straight from centos mirror list. I got mine from Quadra.Net I think

Whoops did some research and answered my own question. Thanks for your help sir.

ok, so I figured out how to burn it as an image and not a file... it unpacked everything and I have all these wonderful files and folders... but now when I put it in my laptop to boot up... it says the following...

ISOLINUX 4.05 2011-12-09 ETCD Copyright (C) 1994-2011 H. Peter Anvin et al
EDD: Error 0100 reading sector 2018812
No DEFAULT or UI configuration directive found!

Did I get a bad copy of linux possibly? Or did I mess something up again?

Thanks for your patience.

Also to answer your possible next question... I used a program called "imgburn" downloaded from www.imgburn.com to burn the image. The computer is an HP dv6-6b47dx.

[TrevorH]

That looks like a bad DVD or a bad burn. Got any different type of disk to try instead? Or just a different one perhaps.

[JoshBock]

I tried burning it again (same type of dvd) and same response. Is it possible the image burning software isn't burning right?

[TrevorH]

Anything is possible. I don't have any experience with any Windows burning software so don't know. Did you already verify that your download is correct? There are files on the mirrors, in the same directory as the iso files, that contain various checksums to allow you to confirm that the file that you downloaded is the same as the one on the mirror.
