I have installed MEPIS, debian, knoppix, kanotix and ubuntu countless times. And many other operating systems. If you want to do it so you can install easily then I would advise getting a good partition editor. There are many out there. I use gparted. It is run like a live linux cd and is really easy to use.
One thing to remember when burning an iso is that you must check the md5sum .
See this thread.
http://www.linuxquestions.org/linux/...sum_in_Windows
The md5sum is a number that is generated from the binary content of your iso. If the md5sum that you download at the site matches the one that your software can detect then the iso is complete and has no extra goodies (that you don't need, like a rootkit).
If the md5sum matches then burn your iso as an image. I think that is what it is called in windows but i can't be 100% sure. I haven't used windows in a long time. 3 Years or so. I heard that nero can burn isos ok so that may be a choice.
Burn your iso on good media and don't use a cd-rw just a cd rom is fine and will be more reliable.
When you download the iso that you want you should be able to see where to download the md5sum too. It should be right under the spot where you clicked the iso to download. Download the md5sum. The md5sum will be a series of 32 numbers and letters. 32 digits in all. Never burn an iso that doesn't have a matching md5sum. The iso can have malware or be incomplete as to cause trouble down the road and maybe right off.
Create some new partitions. Gparted can shrink your existing windows partition. You need to do this if you want to dual boot ubuntu and windows. Dual booting linux and windows is the best way to experience linux for the first time. .
When you have used gparted to shrink your windows partition be sure to leave 5 or more gigs of free space so that you can still download things into windows if you choose.
You need to create some partitions for ubuntu to install to. The first will be a small partition of at least 5 gigs. This will be your root partition. The root partition will be represented in the ubuntu installer as /. or it may be ./
It stands for root in any case. You format the root partition as ext2 or ext3.
Now you need to create a linux/swap partition. This partition will only need to be 1 gig or 1000Mb in size. be sure to format it as linux/swap.
Now that will give you 3 partitions and you can only have a maximum of four primary partitions on a hard drive. The way to get around that is to make your fourth partition an 'extended' partition. This 'extended' partition must use ALL of the free space that is left on your hard drive. An 'extended' partition can be divided up into as many smaller partitions that you may need down the road.
You will now create a home partition out of some of the free space in the extended partition. I usually use between ten and twenty gigs for home. Depends on how big the drive is.
When you are installing with the ubuntu installer you have to tell it where you want the root partition to be, where the swap is and where the home is. The partitons will be the ones that you created with gparted or the partitioner of your choice. This is the same method I use for installing MEPIS. MEPIS is similar to installing ubuntu but I think that the installer MEPIS uses is a bit easier for a new user. But ubuntu will dojust fine.
Ubuntu will load grub (Grand Unified Bootloader) in the Mbr of hda. Then when you boot up you will have a choice between windows or ubuntu.
If you want a dual boot system with ubuntu and windows then ubuntu can do it for you without much pain. Hope this helps you a bit. Feel free to ask any question that you may think of.
There are no silly questions. Not asking is silly though.
One more thing that i forgot to add. you may need to go into your computers bios and set it so it boots from the cdrom first. Then your cd should be detected. Does the cd work on another computer?
In a VERY stubborn dell I had to uncheck or disable the option to boot from the hard drive in bios. No matter what I set the bios to it would race staright to the empty hard drive and try to boot. By unchecking the option to boot from the hard drive your system will most likely be able to read the cd. You can still install to the hard drive with the option to boot from the hard drive disabled in bios. Just be sure to re check the box to boot from the hard drive in bios before you try to boot. Or it won't work.
