这是网站的提示信息

Insert the drive (any data it contains will be erased!)
Run dmesg in a terminal: this will give you the location of the stick in square brackets, such as sdb
To write the image, run sudo dd if=GNOME-3.4.iso of=/dev/DRIVE bs=8M conv=fsync, replacing DRIVE with the location
Once the write operation has finished, you can reboot with the USB drive inserted (you may have to specify the boot device on startup)




用网站上提示的在ubuntu11.10下插入u盘然后sudo dd if=...of..命令将gnome3.4.iso写入u盘，完成后重启，
用u盘启动提示

isolinux.bin missing or corrept,

在win7下用ultiso将gnome.iso写入u盘，重启，

出现圆圈，转了会出现提示

dracut warning:unable to process initqueue
/dev/disk/by-lable/gnome4.3.iso-livecd does not exist

悲摧啊弄到半夜3点，没网还是从网吧下的镜像

安装方法看下面，无需下载ISO：
