Hi all, On a F18, I installed livecd-tools-18.15-1 I downloaded CenOS6.x minimal .iso and with livecd-iso-to-disk the resulting USB is never bootable: the computer doesnt boot on it. Tested on many computers. The fact is I succeded to install CentOS on a Netbook (no CD/DVD tray), but I dont remember how I invoked livecd-iso-to-disk. I tried with many combinations (/dev/sdc is the USB pendrive): 1°) $ sudo livecd-iso-to-disk --format --force <ISO> /dev/sdc 2°) $ sudo livecd-iso-to-disk --format --force <ISO> /dev/sdc1 3°) - Format with VFAT on partiion #1 then $ sudo livecd-iso-to-disk <ISO> /dev/sdc1 4°) - Format with Ext on partiion #1 then $ sudo livecd-iso-to-disk <ISO> /dev/sdc1 ... N°) I dont remember what I tried, but it was many, mostly tried with CentOS 6.2 Please, if someone has a F18 + an USB drive: would you test and see if you succed? If you ever succed, how did you? -- RMA.
