How to format used Centos 5.5 system?

by Magma24 / November 15, 2012 7:25 PM PST

I have recieved a laptop running Centos 5.5 from a person who did not want it.

When I start up the system it asks for a "hpsn" login. I do not know the username and password for that, so I want to know, could I somehow format the hard drive and install the system from scratch and have my own login so that I can use the Centos system on the laptop?

http://en.wikipedia.org/wiki/CentOS shows it's a Linux variant especially for servers. You might be more happy installing a more consumer oriented variant like Ubuntu.

All Lunix-variants are free downloads.

Installation?

So how would I install, for example Ubuntu, over this CentOS system?

Would I be able to burn it on a CD, insert the CD on startup and hence overwrite the CentOS installation?

Yes, that's how to install Linux.

That's how to install any OS, in fact.

I find Ubuntu too big to fit on a CD (although it should fit on a 700 MB one). But it works fine if you burn to DVD. Not a problem for most laptops.

CentOS system overwrite?
by Magma24 / November 15, 2012 8:33 PM PST

It says on the Ubuntu website that Ubuntu desktop can be burned to a DVD and installed to either replace Windows or Mac OS or run alongside them, are you sure this would be the same case with the CentOS system?

Also the laptop I am using for this is an Optima Centoris G200 , which looks a bit old to me, would the latest version of Ubuntu be compatible with this machine?

One last thing, so all I have to do is just download Ubuntu desktop (should I download the 64 bit or 32 bit version?), burn it to dvd, and then insert it into the laptop as I start the CentOS and just follow onscreen instructions from there?

Use the 32-bit version and do as you described. It might ask if you want to install it in the current partition (if it finds it OK), and/or let you delete it and create a new one all to its own wishes.

I tried using a windows Xp SP3 CD to install onto the system but it still booted the CentOs system and onto the hpsn login prompt of which I do not know the details.

The same happened when I had tried the Ubuntu 12.10 DVD, it just ignores the CD/DVD and doesn't give me a chance to install a different operating system, any ideas?

When the CD fails to boot
by R. Proffitt Forum moderator / November 17, 2012 7:04 AM PST

You look at the CD by testing if it boots elsewhere. I find new to this folk continue to place the .ISO file on the CD/DVD rather than create a CD from the ISO (yes those are two different procedures.)

Once you know the CD is good then you look at the PC. Old CD/DVD drives often lose that boot capability. Smile as they ask how to fix an old CD Drive.

How to burn Ubuntu?
by Magma24 / November 19, 2012 7:10 PM PST

Well, I had downloaded the ubuntu 12.10 desktop iso file and burned it to a DVD disc, when I try to boot my fairly modern laptop (I had bought it only a couple of years ago and it runs Windows 7) with this DVD disc it does the same thing, it just starts windows 7 & and ignores it.

Wouldn't a modern laptop have the capability to boot of a CD/DVD?

Since this didn't work on my modern laptop, I think burning the Ubuntu 12.10 iso file to a DVD disc was not the correct procedure, so do I have to create the DVD from the iso file? If so how do I do that?

Problem with installing
by Magma24 / November 20, 2012 3:09 PM PST

Well, I burned the DVD in the way suggested on ubuntu.com, and this time when I put in the DVD at startup it comes up with icons ( looks like a keyboard and a man in the star formation).

If I don't press a key before these icons disappear, then the ubuntu menu does not come up. When I do press a key in time, the menu shows the ubuntu logo and several options.

The options in the menu shown include:

Try Ubuntu without installing

Install Ubuntu

Check disc for defects

Test memory

Boot from first hard disk


When I select "Install Ubuntu" it brings me to a black screen with an insertion point at the top left, and nothing happens after that, even when I press random keys on the keyboard.

The same happened when I selected the option "Check disc for defects".

Why is this happening? What am I doing wrong?
