Make a Windows Boot Disk, By going to -
start/settings/control panel/add remove programs/
and click on the startup disk tab, Then click create disk.
Make sure you have backed up all your important data, such as pictures, documents, emalils etc. because all of these will be deleted.
Also make sure you have all your drivers on CD, If you don't you might be able to download them.
Then restart your computer with the startup disk in drive a and start the computer with CD ROM support. when you come to the a: prompt type -
Then delete the current partition that you are using. (I think it's number 3)
Then after it's deleted it create a new one in fdisk (I think its number 1)
Then when you get back to the a: prompt type
Then at the c prompt type
Then you'll get a m,essage asaying all data on non removable drive c: will be erased, so just say yes
After it's formatted put the windows ME CD in youre cd drive and type
X being your CD Drive.
Then windows ME will install, after that, instal all your drivers and stuff, all your programs and data.
