New Installation - No operating system found

Post by JosiahEarl » 2010/01/12 21:29:02

Hi!

I'm new at Centos, although I am familiar with Redhat.

I have a laptop that has Windows XP installed on it, and I want this to run Centos 5.3 instead.

I read some tutorials online, where I found the download "CentOS-5.3-i386-LiveCD". I burned this to a DVD-RW. When I put the disk in my drive and look my my D: Drive it reads: DVD RW Drive (D:) CentOS-5.3-i386-LiveCD.
>I am burning with Nero 7 Essentials.

I place this in the laptop disk drive, bring up the BIOS, set it to boot from CD, and when I boot it up I get the message "No Operating System Found".
I also tried this from another computer, Windows Vista Home Premium, and it skipped the priority boot (which I set to CD) and went right to the hard disk, booting up to Vista like normal.

I hope I'm just doing something wrong.. When I go into the DVD, I first of all see a folder labeled "LiveOS" - Then inside ->
-osmin - IMG File - 12.0 KB
-squashfs - IMG File - 677 MB

Please let me know what I can do!

THANKS!

Josiah

You have to burn ISO to disk, not create a bootable disk.

Thanks for the reply!

I opened Nero and selected "Burn Image to Disc", selected the image file and burned. Should it have looked different? I'm I doing something wrong?

Something amiss. You should be using the current [url=http://wiki.centos.org/Manuals/ReleaseNotes/CentOSLiveCD5.4]CentOS 5.4 LiveCD[/url], but that does not explain the problems. The entire contents of the 5.3 disk should look something like:

If you had just burned the ISO as a file, you would only see the single .iso file. Perhaps something was wrong with the download, or the burning process. See

Hello,

I downloaded the current CentOS 5.4 LiveCD and burned it to my disk.

I think the problem at this point is the burning process, because it does not burn to one OSI image on the disk. I am using a DVDRW - does that make a difference?

When I go to Nero and "Burn Image to Disk" - I select DVD - then burn.
>it goes through the whole burning process, verifying the burn afterwards.
>it says successful

When I go to Computer -> D: -> I just see the contents of the download there - the IsoLinux and LiveCD folders.

Do you recommend using a different program or media?

Thanks!

Nevermind! My wife called me from home saying when she started the computer up, something called "Centus" came up and she couldn't get to windows. She removed the disk and could boot up fine.

I let you guys know if something doesn't work. Thanks a lot!

Josiah
