[Ubuntu 9.10] Installed windows 7, grub is messed up

Michio · 11-25-2009, 08:52 AM

Installed windows 7, and it replaced grub. Booted from live CD, reinstalled grub, navigated to /boot/grub/, and there isn't a stage1 directory or a menu.lst file.

Please tell us you partition setup and exactly how you installed grub. For example, I always use the grub shell method:

Suppose that your linux / is on partition sda2, and there is no separate partition for /boot.

Code:

grub    ##starts the grub shell
root (hd0,1)   ##tells grub where /boot is  (drive 1, partition 2)
setup (hd0)    ##installs grub to the MBR of drive #1

How do I figure out what partition my root is on?

Does this help any?

If you install UBUNTU 9.10 using the default GRUB than you have GRUB2
that means that you do not have a menu.lst .
But you do have grub.cfg
And if you have GRUB2 remember that sda is still hd0 but the first partition is 1 so it starts with (hd0,1)
Why do have a unallocated space of about 20 G , if you allocated it you're partition number can change

Well, the only Linux partition (other than swap) is sda3, so that's certainly where I would expect to find "/" and "/boot".

Off-topic: What's the unallocated space for? The way this disk is setup, it's doubtful that you will be able to use it (except to expand sda1 and 2.)
