If you cannot follow these steps I suggest u STOP posting on these forums. Its pretty straight forward.
What you will need to do is get yourself a copy of the Ubuntu live cd. Which can be found here:
www.ubuntu.com
Now that you have Ubuntu on CD just pop it into your CD drive and reboot your computer. (Make sure that your computer is set to boot from CD before Hard-Drive -- You may need to go into your BIOS to do this, unfortunately since each bios is different I can't explain exactly how to do it on your machine, but once in BIOS you will be looking for the boot order and you will want to set the CD/DVD drive to a higher priority then the Hard-Drive)
Once you boot from the LIVE cd, make sure your SD card is in your card reader and attached to your computer, and you should be able to login with no username and no password necessary. After it has finished loading up you will want to click on SYSTEM > ADMINISTRATION > Partition Editor. (Found along the top of your screen)
At this point it may ask you for an administrative password, which, in the case of the LIVE cd is blank and you just need to click OK.
Now in the top right corner you will want to make sure you select your SD card, use the size of the card for reference.
Next right click on the partition and select "Unmount"
Then right click again and select "Delete"
Next right click once more and select "Add"
Finally set your size for your new partition in MB. Make sure to set your filesystem to fit your needs.
FAT32 IN UR CASE.
After you've made all your changes, make sure to click the checkmark icon that says "Apply" and let it do its magic.
And thats it, you can add as many as you have room for or need. Once done, make sure to shut down and remove the CD and you will be good to go.
One thing to note however: Windows will only assign a drive letter to the first partition on the SD card, I'm not sure why as Ubuntu seems to pick up the others fine.
--- U can copy ur Apps folder in Windows as windows will only see the first partition. Boot up USBLOADER 1.4 on ur wii and it will ask u to partition... select the SECOND PARTITION. u can now store apps and homebrew on PARTITION ONE, and Wii games on PARTITION 2.
