Booting a live cd?

[synack]

Ive tried booting to the most recent ubuntu iso but for some reason when I select it from the boot menu it says somthing about append a correct “root=”. Could there something be something wrong with my /default file? I have my ubuntu iso mouted to /tftpboot/ubuntu/12.10/

[CODE]LABEL ubuntu
kernel tftpboot/ubuntu/12.10/casper/vmlinuz
append boot=casper netboot=nfs nfsroot=192.168.0.3/tftpboot/ubuntu/12.10/
initrd=ubuntu/12.10/casper/linitrd.lz[/CODE]

Try it without the tftpboot listed in the kernel line, maybe?

[CODE]LABEL ubuntu
kernel ubuntu/12.10/casper/vmlinuz[/CODE]

I’m just guessing because I’ve never tried booting to the ubuntu live cd, but the structure of my default file doesn’t include the tftpboot folder in the kernel line. I wonder if it’s looking for a file located at /tftpboot/tftpboot/ubuntu instead of /tftpboot/ubuntu because of it.

Hi,

Shouldn’t nfsroot be set as nsfroot=192.168.0.3:/tftpboot/xxx (with the “:” between the IP & the NFS path)?

Cheers,

[CODE]append root=/dev/nfs initrd=/ubuntu/12.10/casper/initrd.lz boot=casper netboot=nfs nfsroot=192.168.0.3:/ubuntu/12.10[/CODE]

Your append line should look like this. Note the “root=/dev/nfs”
you will need to test if you still need your “initrd=” line because it is in the append line.
