Just for fun, try changing the UUID number to /dev/sdwhatever, and see if that helps. (This is an issue I've run into on Asus netbooks, but haven't yet had a chance to try to reproduce. I'd be curious, even though I frankly admit, I'm probably wasting your time.)

Where do I change the uuid. I'm willing to try anything.

Sorry, should have been clearer. (But, I was also being lazy, as I didn't know if you'd want to bother with what is, after all, a bit of a long shot.)
While in your working kernel, edit the file /etc/grub.conf.

You'll see a line looking something like

kernel /boot/vmlinuz-2.6.18-164.15.1.el5.centos.plus ro root=LABEL=/ rhgb quiet

(However, yours will look quite different--that one is cut and pasted from CentOS, yours will have a vmlinuz-2.6.30-something and be saying Fedora, rather than centos.

You'll also see in that line that yours says something like root=<very long number>. Change the <very long number> to root=/dev/sda5 or whatever your root partition might be. If not sure, you can find that out by typing the command

mount

This will give you back several things including something like

/dev/sda5 on / type ext4 (rw)

What I like to do, especially when testing, is just put a # sign before that line, which means I'm making it into a comment, rather than command.
Then, copy the line. but leave out the # in front.
In the new line (the one without the # sign)
change the root=<longnumber> to root=/dev/sdX where X is your root partition, e.g., /dev/sda5 or /dev/sda2, or whatever your root partition is.

It's very late here, and I have to sleep, so if this was incoherent, just ask and I'll try to be clearer tomorrow.

Flash drive may have been problem. Reinstalled F13-i686-live. iso using Unetbooting and it will now load on the Acer Aspire One, may install tomorrow. When I do this time I'll get rid of the LVM that got on by accident.

Flash drive is a DataTraveler 4 Gig and it's known to have boot problems, funny thing is I have two of them no problem with one but not so lucky with the other.
