Installing Centos on previously encrypted Windows laptop


I have an old Dell laptop which currently has Windows XP on it, and was encrypted with SafeGaurd Easy. I wish to re-purpose the laptop with Centos.

I downloaded CentOS-6.5-x86_64-netinstall.iso to my Windows 7 PC, right-clicked on it, and burned it to a DVD.

I put the DVD in the laptop, hit F12, and booted off the CD.

The Centos screen came up, I entered my location and language, but then I got a "Disc Not Found" error stating that "The CentOS disc was not found in any of your CDROM drives".

Please provide any suggestions.

Thank you

Sorry, rookie mistake. I need to do a URL install.

Interesting, however, I later burned the full DVD centos, and it wouldn't boot off it.

I assume the drive is so old that you need to use best quality optical disc's and maybe only -r or +r instead of rw. Burn at the very slowest speed possible. Drive could be flakey.

If possible, consider usb boot maybe. Network install isn't bad if you have time.

Thanks for the update and solution.

HOW exactly did you burn the dvd iso to the disk ?
what software did you use ?

xp has NO built in tool to burn a ISO
you have to use a third party tool

there is a good FREE tool called
" CDburnerXP"
https://cdburnerxp.se/en/home

use the very slowest burn speed
x2 or x4

Hi John, No, the old target laptop had XP on it. I burned the DVD iso using Windows 7. It appeared to work.

Hi jefro, Well, the old drive worked with the netinstall iso, so it appears to be okay, no? Thanks for your help.

what program on win7 ?
win7 dose not have the built in ability to burn a dvd iso
NERO dose if that is installed
that is if you bought it after the trial version expired

if not
CDburnerXP will run on windows7 64 bit just fine
and is able to burn a dvd " as a image "

you have to use " burn as IMAGE"

I feel like a knob saying this, but I right clicked the downloaded file on my Windows 7 PC, and pointed to the DVD, and it worked.

the r-click in windows will save a DATA dvd
basically a " copy / paste"

and a data dvd is NOT bootable

to make a dvd that is bootable from a ISO image you need to burn the dvd
" burn as image"

If it booted from the CD, I think that (at least the boot sector) got burned properly.

However, like JohnVV, I would suggest you get ImgBurn or something similar to burn the ISO. And when you burn it, set everything to the slowest speed possible (usualy 1x or 2x).

If you want to try it with a USB stick instead of burning through a stack of DVDs, I use Win32 Disk Imager. Just make sure that you don't have anything important on the flash drive, since it will erase EVERYTHING on it.

If none of the above work, you might want to try the full DVD instead of the Internet install.

I've had good experience with ImgBurn as well.
As above, using the slowest speed possible and burn as ISO Image, not data is good advice.
