虚拟机开机出现dracut_Centos7 U盘启动盘安装报错 dracut-initqueue timeout问题

一直都在VM中安装CentOS等各式系统,今天在一台实体机中安装CentOS7,却遇到麻烦了…

下载ISO,使用Universal-USB-Installer制作启动U盘(多年来一直用这个工具),开机引导,卡在:

starting dracut initqueue hook

一段时间等待后,出现:dracut-initqueue timeoutfailed to start switch root

一番搜索后,得到解决方法有:

2. 说是centos6.5开始不支持unetbootin的方式制作的启动u盘,可用dd命令:

dd if=CentOS-7-x86_64-DVD-1511.iso of=/dev/sdd

3. 使用Fedora官方提供的工具Fedora Media Writer制作启动盘;

4. 修改U盘卷标为 CentOS 7 x86_64,方法未验证,来自:

Moreover, the CentOS 7 installer image has a special partitioning which, as of July 2014, most Windows tools do NOT transfer correctly leading to undefined behaviour when booting from the USB key. Applications known (so far) to NOT work are unetbootin, multibootusb and "universal usb installler" - do NOT use these. Confirmed as functioning correctly are Rufus (may depend on options selected, there have been reports of failure with rufus too), Fedora LiveUSB Creator, Win32 Disk Imager, Rawrite32 and dd for Windows.

对于CentOS7,在Window上制作镜像的话,由于CentOS有一个特别的分区问题,所以有些Windows工具就不能正确的将U盘做成启动盘。目前为止不可以的工具有:unetbootin 和 universal usb installer。可以的工具有Rufus, Fedora LiveUSB Creator(现在的名称叫Fedora Media Writer),Win32 Disk Image, Rawrite32和dd。
