Boot failure after GRUB 2.0 installation

Correct. If you need to do the chroot, say so.

What is chroot? It seems to have lots of uses but how does that apply to boot problems particularly?

[dorruk]

By the way, when I got to the command "insmod normal", it says error:unknown filesystem.
It is ntfs. What now?

Then it is the wrong (Windows) partition. What

grub rescue> set

says?

says?

prefix=(hd0,msdos2)/boot/grub,
root=(hd0,msdos2),

I can post a GParted screenshot if necessary.

Hold on, when we are talking about the ubuntu root partition, that's the root partition of your ubuntu install. It can't be ntfs since it doesn't install on ntfs.

Is /dev/sda2 where you put win8/win7, or ubuntu?

The chroot is a procedure to enter inside a linux installation, so any command you run will be like run from within. It can help in a way that it will install its grub2 on the MBR of the disk.

dev/sda2 is Windows 7, which the computer came pre-installed in.
I have not changed the bootflag location ever since, and installed Win 8 and Ubuntu besides Win 7.

Now, should I move the bootflag to Ubuntu partition or sth? Or is it enough to set Ubuntu partition as root on grub rescue?

Ok, what do you get after this:

grub> search.file /boot/grub/grub.cfg root
grub> set prefix=($root)/boot/grub
grub> set

[dorruk]

search.file is an unknown command :/
But ubuntu is installed on dev/sda7 if that's what you're looking for
