Can't boot Live from USB - unknown fs type, can't mount root

[Oliver Ruebenacker]

Hello,

I downloaded Fedora 19 Live CD and copied it to a USB flash drive via dd.
When I try to boot from it on a Lenovo Thinkpad T430s, I do get a screen
that says that Fedora Live CD is going to load, but then it fails. The
first error message I see is:

kernel: SQUASHFS error: unable to read id index table

Then, some lines later, I get several lines that say:

dracut-mount[361]: mount: unknown filesystem type 'DM_snapshot_cow'

and then:

dracut-mount[361]: Warning: Can't mount root file system

And then I seem to be in a "dracut emergency shell"

Any ideas? Thanks!

Best,
     Oliver

One quick thought: Did you verify the checksum of the download?

Now I did - and apparently, I don't get the right checksum.

Didn't think about this. I haven't had a corrupted download in a long
time.

Thanks!

Glad it was something simple.  The only reason I thought of it is that I 
had to make a LiveCD yesterday (My desktop won't boot off of USB.) and 
remembered to do the checksum, JIC.

if you have another FC box try following and user to create live USB-stick

yum install -y liveusb-creator

You have to burn the iso to the usb stick using cd creator or what ever 
you have for the purpose, similar to how one creates a cd or dvd, not 
copy it.
I do this frequently and once the iso is on the stick it doesn't seem to 
matter what else is on it the iso still works( for me anyway). I have  
a2 gig stick that I've used this way for years.

Hello,

After getting the correct ISO file, I just slapped it onto to flash drive
with dd, and it worked.

Interestingly, turning the flash drive into a Windows 7 install medium
was a lot more complicated.

Best,
     Oliver
