Can't mount root filesystem, boot has failed, sleeping forever
I've downloaded Fedora 12 and decided to try and install it on my old laptop which is currently running Ubuntu 9.10 with no problems.
When I boot from the live cd, it starts to load with the 3 bars on the bottom, one on top of the other, one is white, one is dark blue, the other is in between those colours in the spectrum somewhere.... Anyway, the load bars complete and "Fedora 12" turns white, then the following output populates:
mount: unknown filesystem type 'DM_Snapshot_Cow' (<----- repeated a bunch of times)
can't mount root filesystem
Boot has failed, sleeping forever
Anyone know what the problem is here?As wide as were the waters,

Are you sure the live cd isn't corrupted? Also, where did you get the disc and/or iso image that created it?

I'm not sure if the disc is corrupted. It said it was created successfully, the only indication that it could be corrupted is that it won't install.
I downloaded it from Fedora Project, sponsored by Red Hat
I'm installing open suse 11.2 now instead for kicks.
Thanks for your reply Rubberman.As wide as were the waters,

Did you verify the checksum (md5sum or sha1sum) on the image after you got it downloaded? This sort of problem is often due to a very small corruption in the image, and running the checksum is the appropriate way to verify that what you got is what they sent. This is all before you burn the image. Also, you can rerun the checksum on the disc after you burn it to verify that it also agrees.

ah, no I did not verify the checksum. Exactly how do I go about doing that?

Where you downloaded the ISO image or other file(s) from to burn to disc, there should have been a checksum file (a text file possibly ending in md5 or such) with the checksums for the file(s) you downloaded. If they are md5 checksum files (the most common), then once you have downloaded the files, you run the appropriate checksum generating program and compare the checksum value(s) output. These programs generally already exist on Linux systems. For Windows, you will probably have to install or download one - freeware for them is easily available on the net. The name is typically something like md5sum or sha1sum. Open a console window (cmd.exe on Windows) and run the program with the downloaded file name as the argument.

hmmm, the only file that downloaded is the .iso, unless the checksum gets saved somewhere else? I don't run windows, I have windows 7 just to watch blu-ray DVDs with because I can't get them going with linux yet...
what linux checksum program would you recommend?As wide as were the waters,

On the web page where you got the iso image, there should have been either a link to the md5 checksum file(s), or a listing of the checksums on the page. In any case, you REALLY need to verify the checksum of the downloaded file before burning it. A Windows version of md5sum is available here: MD5sums for Windows

Ok, I will go back and check the page for the checksum file. I assume that the linux version is called md5sum as well? Like I said, I don't run windows except to watch blu-ray....

Well, I assume you used Win7 to burn the disc?
