If it's wrong, you'll get a few dozen lines of output and then it'll say "can not mount root filesystem" or something similar. root (hd0,0) would be grub. If it's wrong, you'll get less than a dozen lines of output before the error message. Try mounting first with root=/dev/sda2 or whatever, then double check a) the UUID and b) the syntax you're using, which should be something like: root=UUID=xxx If the root volume isn't a plain disk partition, but is rather a logical voume or mdadm, your initrd will need to include lvm, raid, or whatever else is needed to get the root volume up and running. See also super grub disk, which can be helpful for figuring all of this stuff out. -- Ray Morris support@bettercgi.com Strongbox - The next generation in site security: http://www.bettercgi.com/strongbox/ Throttlebox - Intelligent Bandwidth Control http://www.bettercgi.com/throttlebox/ Strongbox / Throttlebox affiliate program: http://www.bettercgi.com/affiliates/user/register.php On 10/07/2010 12:12:56 PM, Fabricio Archanjo wrote: > Hey all, > > > Sorry because my stupid question, but i don't know more.
