现在需要update吗？

/dev/sda10: UUID="2a294df7-ebaa-415a-ab0e-84388cc284b5" TYPE="swap"

sudo gedit /etc/default/grub
把
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
改成
GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"
存档
sudo update-grub
完成后，重开机。
不行，就要EasyBCD了...

资深高手啊。
好贴；申精@林自明

牛人~高手~

学习一下~

楼主啊，我也折腾了好几天啊，选择的是安装到boot那个区，可是重启之后直接到win8.1.用easybcd引导也不行啊，怎么破？

楼主，要是用光盘呢。。
怎么装。。

是这样的。我用虚拟机实验了一遍。发现没有独立分/boot分区时，就算boot loader默认在sda，也不影响mbr，开机直接进win7。要是分了独立的/boot，并且boot loader还是默认的sda，就会发生启动后进入grub2。麻烦大神指点下。

求指点

用EasyBCD在win7下安装13.04进入不了安装界面总是黑屏是什么原因啦！！

楼主，在吗，我今天安装了ubuntu，一切正常安装，安装启动引导器选的win8所在的硬盘，关机重启后进不去win8，ubuntu能进去，选win8 他就一黑屏又到选择界面了。。。。求楼主帮帮忙！
