Ubuntu and Windows dual system record

1) I am installing Ubuntu on the basis of Windows, related tutorials can be seen http://jingyan.baidu.com/article/60ccbceb18624464cab197ea.html

2) sometimes appear when entering Ubuntu only a horizontal line, at this time please reset EASYBCD, the original Ubuntu deleted, and then join the boot, boot area Remember to set up, for the size of 200M or so of the partition

3) sometimes appear after entering Ubuntu

The workaround is to reset the grub to locate the Ubuntu partition

The first step: Find out where your Linux disk is located in that partition and the Grub directory, and you can pass the LS test

      Grub Rescue>ls           grub rescue>ls (hd0,0)/grub　　  Return  //Loop uses the following command until the contents of the partition are displayed instead of "Unknown filesystem       If we try to (hd0,8), the content is displayed successfully. The second step: Grub Rescue > Set//Display the set format, and reformat the same format as this display        GRUB Rescue>set  root= ( hd0,8)     Enter    //in parentheses for the previous attempt to successfully partition        GRUB Rescue>set  prefix= (hd0,8)/ Grub   Enter   Third step:       Grub rescue>insmod  /grub/normal.mod   Enter//Sometimes the path is not necessarily is Grub/normal.mod, want to see LS (hd0,8)/grub display result, if show no normal.mod, but have i386-pc directory, then write as Insmod/grub/i386-pc/normal.mod        At this point, you should exit the Grub Rescue mode, enter the familiar Grub mode   Fourth step:      grub>normal back Car   Fifth step: Fix grub       Enter Linux system, on command line       sudo  update-grub Enter &N bsp;      sudo grub-instAll/dev/sda
