尝试从 USB 启动“扫描磁盘查找索引文件...”

我正在尝试启动 Ubuntu 14.04.1 LTS USB 棒，但似乎它永远无法进入桌面。

我卡在了启动屏幕上，按下“ESC”键后出现了以下几行：

stdin: Not a typewriter
umount: can't umount /cdrom: Device or resource busy
/init: line 7: can't open /dev/sr0: No medium found

它在“ ”上阻塞很长时间Scanning disc for index files...，然后写入所有后续内容并在下一个 上重新阻塞Scanning disc for index files...。

我使用该usb-creator-gtk程序构建了我的 USB 记忆棒，并启用了持久数据。

因为有人似乎遇到了同样的问题（http://www.reddit.com/r/linuxquestions/comments/2dsgd5/cant_boot_from_cdusb_to_install_ubuntu/）我尝试了那里的解决方案（添加nomodeset），但我仍然得到相同的结果：在启动屏幕上被阻止（并没有真正挂起，因为小点仍然“活着”）......

有人知道发生了什么吗？

答案1

我终于找到了一个解决方法：我创建了一个 USB 记忆棒持久数据已禁用，终于可以正确启动了！

我受到启发评论 15的漏洞 chapuzzo 指出我。

答案2

尝试复制整个文本，这样更有帮助：

如果您遇到此错误，当您从 USB 启动时，按 F6 然后编辑启动选项：删除此项：

file=/cdrom/preseed/ubuntu.seed

添加这些：

live-media-path=/casper/ ignore_uuid

完整示例：

append boot=casper initrd=/casper/initrd.lz live-media-path=/casper/ quiet splash ignore_uuid

如果你不想每次从 USB 启动时都进行编辑，你可以在 USB 中编辑此文件：/syslinux/text.cfg
