"yes i just want ubuntu on my netbook because it is an acer aspire one from 2007 that runs win xp very slow and i have a feeling if i delete xp and just use ubuntu everything will be a lot faster."
I take it you wish to install Ubuntu Netbook Remix (http://en.wikipedia.org/wiki/Ubuntu_Netbook_Remix)? This is recommended.
Very well. Begin by downloading an early version (1.3.5) of SystemRescueCD at sourceforge (http://sourceforge.net/projects/systemrescuecd/files/sysresccd-x86/1.3.5/)
Next, get UNetbootin from the same source (http://unetbootin.sourceforge.net/). Then make a bootable small USB Flash Drive using UNetbootin and the sysresccd-x86-1.3.5 ISO file, both just downloaded.
Set your system BIOS to boot to USB first, then boot to your new System Rescue CD USB stick.
After it boots, SysRescCD want you to hit defaults (hit Enter) a couple times. When you end up at the multi-colored prompt on the page asking user to enter either "startx" or "wizard," type in the following command
dd if=/dev/zero of=/dev/sda bs=4096 conv=notrunc,sync
which will destroy all trace of any Windows File System, wiping your entire hard drive with zeros. It will take a while, depending on the size of your hard drive, so go make a sandwich or something. When it's done, you'll see some statistics after a statement that there is no "more space on drive" and the size of your had drive.
Don't bail out yet!
At the same prompt, type in the desired startx and Enter
This brings up the XFCE mouse then a yellow-colored terminal.
In the yellow-colored terminal, type the command gparted .
Partition your hard drive. If you don't know how, use the Slackware basic strategy of one partition for root ( / ) -- 10GB (to copy DVDs use 15GB), using ext4 file system;
one partition for swap -- one gig should do; and
one partition for /home -- most or all of the remainder (keep some unallocated should you desire to expand one or add a partition later).
NOTE: when, in the OS install, partition dialog pops up, choose Manual and then either Edit or Modify for each partition created previously with gparted, telling it to yes, use the partition, format it using ext4 file system for / and /home; swap should be okay. [So, write down how you partition, noting /dev/sda1 or sda2 or sda3, size, label (if any), and file system (ext4)] -- it's easy.
When done partitioning, suply enter the command init 6 and reboot follows.
