使用img檔案作USB開機碟

用MeeGo安裝檔案作例子
確認好USB的裝置名稱

下指令:
dd if=meego-netbook-ia32-1.0.0.20100524.1.img of=.dev/sdb1

查詢USB碟或其他裝置

使用: sudo fdisk -l

Disk /dev/sda: 160.0 GB, 160041885696 bytes

255 heads, 63 sectors/track, 19457 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sdb1 2 2495 7839743 b W95 FAT32

這就告訴你, usb碟是 在 /dev/sdb1

查看mount點

使用: mount

/dev/sda3 on / type ext4 (rw,errors=remount-ro)

tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)

proc on /proc type proc (rw,noexec,nosuid,nodev)

sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)

udev on /dev type tmpfs (rw,mode=0755)

tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)

devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620)

/dev/sda1 on /media/sda1 type fuseblk (rw,allow_other,blksize=4096)

/dev/sda5 on /media/sda5 type fuseblk (rw,allow_other,blksize=4096)

fusectl on /sys/fs/fuse/connections type fusectl (rw)

/dev/sdb1 on /media/Transcend type vfat (rw,nosuid,nodev,uhelper=hal,uid=1000,shortname=winnt)

就可以看到/dev/sdb1 是mount在

/media/Transcend 之上
