Welcome to the forums Daveman.....
If you want to try another install of the os do this.
If the version of Win.ME that you have is a full version you can do a complete install from the CD.
But if it is an upgrade you will need an earlier version of Windows to show it when asked for a compliance check, Such as Win98, Win95 or 3.1 you get the idea.
OK here is what you need to do.
First go here <http://www.drd.dyndns.org/index2.html
> and download the WinME boot disk.
WinME is FAT32
Boot to this new boot disk.
Select boot with no CD Rom support.
At the A:> Prompt type fdisk /mbr Enter
At the A:> prompt again type fdisk, When the prompt comes up about large disk support select yes.
Then select option 3 Enter
Select option 1 Enter
Type in the Volume Label if there is one and hit enter.
Are you sure Yes.
Now you need to Format.
Boot to the floppy without CD-Rom support.
At the A prompt type format c:
When it's finished you can enter a volume label such as hard drive or you can leave it blank.
Now boot to the floppy one more time, This time select boot with CD-Rom support
At the A prompt select E:\ enter.
This is assuming you have one hard drive and one CD-Rom. The E could be an F or some other letter depending on the amount of IDE devices you have.
With the WinME CD in the drive type setup, Enter this should start loading the Operating System.....
