断电以后打开UBUNTU卡在sysenter_do_call+0*12/0*12 处

里面存东西了，不想重装，求大神支招如何修复

你这等于什么都没说。这个只知道是内核崩溃了，先找个livecd/liveusb之类的东西磁盘检查，如果内核文件/驱动文件挂了去网上下对应安装包把文件覆盖一下
另外重装只要不格盘，你存的东西又不会丢，就算有改动的会被覆盖，用livecd/liveusb导出来备份就是了

怎么进行磁盘检查？

就是上面这个截图，我有LIVECD，能不能帮我看看怎么修？

livecd 进去先把重要的资料备份一下，然后把/boot/grub.cfg发上来看一下
开机出来启动菜单时，试一下进入高级模式recovery mode，或者进入其他内核引导
如果修复不成功覆盖安装不格式化也可以保留之前的用户数据，有冲突的系统文件会删除

我的UBUNTU版本和LIVECD的版本不一样能覆盖安装不？

1. 使用 Ubuntu Live CD 開機
登入 試用桌面
2. 把下面指令 複製 貼進終端機 執行
2-1. sudo efibootmgr -v
2-2. sudo parted -l print
2-3. 把結果全部直接 選取/複製/貼上來
3. 請說明 你安裝 Ubuntu 時 把 / 掛載在哪個分割區 ?

root@ubuntu:~# modprobe efivars -v
root@ubuntu:~# parted -l print

Warning: Unable to open /dev/sr0 read-write (Read-only file system). /dev/sr0

Error: Can't have a partition outside the disk!

/挂载在逻辑分区上

1. 你是指 /dev/sda8 ？
2. 如果是
登入 試用桌面
把下面指令 複製 貼進終端機 執行
sudo fsck /dev/sda8
2-1. 如果順利完成
重新開機 看看
2-2. 如果有錯誤訊息 全部複製 貼上來
不要摘錄

被我折腾的现在彻底怀了，WINPE、UBUNTU安装盘都进不去了
