Fix Ubuntu12.04 + Win8 dual system startup

1. I used Ubuntu12.04 + win7 and started grub normally. Recently, when I caught up with Win8, I had to clear Windows 7 and set up Win8, and then I went wrong. It hurts a lot. Only win8. 2. The main things are all in Ubuntu12.04 + VMware8.04. this startup item must be fixed before it can be achieved. 3. After several days, baidu and google were all float clouds. Finally, they found that the optical drive was broken and they found a usb Optical Drive. Later

1. It is normal to start grub with Ubuntu 12.04 + win7. Recently, when I caught up with Win8, I had to clear Windows 7 and set up Win8, and then I went wrong. It hurts a lot. Only win8.

2. The main things are all in Ubuntu 12.04 + VMware8.04. this startup item must be fixed before it can be achieved.

3. After several days, baidu and google were all float clouds. Finally, they found that the optical drive was broken and they found a usb Optical Drive.

Later, I carved out Ubuntu 12.04. After the disc was started, I opened the terminal (Ctrl + Alt + T) or simply tried Ubuntu to go in and try again.

4. The command is mainly as follows:

The first command sudo fdisk-l

View Original partition information.

Find the heap of/dev/sda. Find the last few linux's 83.

My machine is/dev/sda6

I ran sudo su once. Let's take a look.

Article 2 mkdir/media/user)

Article 3 mount/dev/sda6/media/user (mount the partition installed in linux to the new directory)

Article 4 grub-install -- root-directory =/media/user/dev/sda)

See such a thing. Installation finished. Then I wrote blabla in a bunch of English letters, which may affect startup.

After restart, sudo su

Update-grub2 (update grub. cfg)

5. After the restart, the dual-cloud startup is complete.

To delete non-empty multi-level directories, use rm-rf/media/user (using this command, it is because I used a 10.04 disk to do it again, then the gub version is too 2. I even listed 8 menus in black when I started them. After I deleted them, I carved a new 12.04 sheet, and the remaining few items were in the same color as the startup)

6. Pay attention to the hybrid boot of Win8, which may affect the menu. In this case, you can use gpedit, management template, system, and shutdown to disable faster.
