DellInspiron14R is installed with WIN7 and Ubuntu10.10, And the Grub system fails.

I bought a new version this year. I used to learn Linux for a while and forgot about it. But I still feel that I am interested in Linux, especially Ubuntu. So I started to learn Ubuntu again, the first WUBI was installed with 10.04, but it was a tragedy after each update-win7 could not go in at all, so we had to go to the school's network center and let the experts do it for me, in fact that after the update and GRUB option to fix GRUB thing now seems indeed a piece of cake, understand this on the line: http://www.lin

I bought a new version this year. I used to learn Linux for a while and forgot about it. But I still feel that I am interested in Linux, especially Ubuntu. So I started to learn Ubuntu again, the first WUBI was installed with 10.04, but it was a tragedy after each update-win7 could not go in at all, so we had to go to the school's network center and let the experts do it for me, in fact, the updated GRUB option to fix GRUB seems to be a piece of cake now. Just read this: http://www.linuxidc.com/linux/2010-10/29368.htm. let's get back to the point. We can see the problem that Windows 10.10 and Ubuntu cannot go into the system after Windows 14R is installed (that is, black screen or no module name found is displayed after Windows is restarted ).

1. Specific symptom description:

After Ubuntu 10.10 is installed with a USB flash drive, a CD, or hard disk, It is very happy. Then I think of playing in WIN7, so restart, select the startup project to go to win7, and then shut down and restart, no system is allowed to access the black screen.

2. solution:

You can also use a USB flash drive to create a boot disk or a CD. Make the boot disk on the home page of Ubuntu. Just make a disk like that. Then insert the USB flash disk or CD, start the system from the CD or USB flash disk, and then select the liveCD mode. In fact, the LIVECD mode is the first one on the boot disk: Try Ubuntu, and then enter the Ubuntu interface in a moment, in this case, open the terminal and enter the repair grub step.

Go to repair GRUB, steps can refer to http://www.linuxidc.com/Linux/2009-07/20848.htm

Unfortunately, according to this method, the following error occurs: grub> find/boot/grub/stage1.

As mentioned in the previous article, grub cannot be repaired. Therefore, google again and find that grub can be repaired using this method:

After the repair is complete, use find to take effect. Restart it and you will see the GRUB boot interface. How can I start your installed Windows 7 and Ubuntu, let's take a look at this:

Http://www.linuxidc.com/Linux/2010-10/29368.htm

Windows 7 cannot be used when Windows 7 is started in DELL migration 14R.

Grub> rootnoverify (hd0, 0)

Grub> chainloader + 1

Grub> boot

The above is a DELL detection tool. Start Windows 7 because it is in the second partition, so write as follows:

Grub> rootnoverify (hd0, 1)

Grub> chainloader + 1

Grub> boot

After Windows 7 is started normally, the DELL datasafe software under Windows 7 is deleted, including local and online. This processing method has been viewed on foreign websites, and I do not understand the specific principle, I tried it like this. Entering WIN7 and then restarting will not affect the startup items.

I'm a Linux cainiao. You can share some good ideas. This article is mainly intended for DELL think14r and Ubuntu 10.10. For other Ubuntu versions, google it when you fix grub! Please correct us for any errors!
