I want to install F8 from a 1GB pen drive but dd does not work, although I can mount it. dd shows it worked: # dd if=/home/cpn/Desktop/Downloads/diskboot.img of=/dev/sdb1 24576+0 records in 24576+0 records out 12582912 bytes (13 MB) copied, 0.307408 s, 40.9 MB/s But there is nothing in the directory: [root@dkt ~]# ll /media/KINGSTON/ total 0 fdisk -l shows strange messages: # fdisk -l Disk /dev/sda: 81.9 GB, 81964302336 bytes 16 heads, 63 sectors/track, 158816 cylinders Units = cylinders of 1008 * 512 = 516096 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 203 102280+ 83 Linux /dev/sda2 204 158816 79940952 8e Linux LVM Disk /dev/sdb: 1027 MB, 1027604480 bytes 32 heads, 62 sectors/track, 1011 cylinders Units = cylinders of 1984 * 512 = 1015808 bytes This doesn't look like a partition table Probably you selected the wrong device.
