Did you remove the Live CD ?

This happens to me too since I have two drives (CD Writer and DVD-ROM) in my machine. To make it detect the CD for install I need to put it in the DVD-ROM.

Oh, sorry, I forgot to add that I'm not using a CD.
I used the program Unetbootin to write the ISO to a tumbdrive so that I install it to another thumbdrive.
Yeah, I know its a little roundabout, but its the only way I could find to create an actual install on a thumbdrive.
Also, same thing happens in the Cooking version.

Does this help?

Can anyone help me? Nothing is working. I can't find any way to install SliTaz to a thumbdrive.

http://doc.slitaz.org/en:guides:liveusb is the guide you need. Is that what you read? It sounds like unetbootin worked the first time so why not the second time? If you want to add your own packages you can try to make a new livecd and use that iso for unetbootin (I think?)
good luck.

Okay, I burned my iso to a cd, and booted it up on my desktop. It has all kinds of graphical errors. When I tried to boot it on my other desktop the gui would not even load. When booting the cd on my laptop it froze.
After I tried to erase the cd and put the cooking version on it but it looks like SliTaz corrupted the cd and its about as good as a Frisbee now. I am annoyed.

Is there any easy way I can just make a non-live install of SliTaz on a thumbdrive? It should not be this difficult.

Does anyone know?
