Laptop dead need HELP! (solved praise God!)

[mowens01]

I was trying to remove another install of kubuntu on my laptop and after getting the advice and trying that my laptop will not boot at all all it says in grub rescue. Please help. My original post is removing kubuntu from Win7 partition.

Re: Laptop dead need HELP!

Get a LiveCD, boot from the CD, go to the "try" option. Once done that, boot up a terminal, and find your partition with

sudo fdisk -l

Note: that is a lowercase "L"

once you find the right partition, mount it with

sudo mount /dev/sdXY /mnt

Note: XY being the last two characters of the drive.

Once done that, you should be able to

sudo grub-install --root-directory=DIR /mnt

to install GRUB back onto your computer, then you unmount the partition

 sudo umount /dev/sdXY /mnt

and restart

sudo shutdown -r now

I believe those are all the correct codes, it is what I did when I needed to reinstall GRUB just earlier today

Re: Laptop dead need HELP!

How do I know which partition to use would it be the one with linux as the system?

[Linkmaster]

Re: Laptop dead need HELP!

If you left Linux on the computer, then most definitely use the Linux partition

Re: Laptop dead need HELP!

It keeps telling me the unmount command is not found?

Re: Laptop dead need HELP!

As Vinny said, its umount, it looked like "unmount" my first time as well, but its simply umount.

Re: Laptop dead need HELP!

it is not wanting to work for me here is what I have done os far.

ubuntu@ubuntu:~$ sudo fdisk -l

Disk /dev/sda: 4040 MB, 4040724480 bytes
125 heads, 62 sectors/track, 1018 cylinders
Units = cylinders of 7750 * 512 = 3968000 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xbb0eb409

This doesn't look like a partition table
Probably you selected the wrong device.

I am not sure what I am doing wrong.

Re: Laptop dead need HELP!

I went searching through the internet to find the exact post that I used to reinstall GRUB for me, and I found it...finally:

Reinstalling GRUB 2 from LiveCD
If you cannot boot from GRUB 2 and need to reinstall it, here is the simple method. For more details or for advanced options, refer to the Ubuntu community documentation here: Grub2 - Reinstalling GRUB 2:
Boot the Ubuntu Live CD (Try without installing).
From the Desktop, open a terminal - Applications, Accessories, Terminal.
Determine your normal system partition - `sudo fdisk -l` (That is a lowercase L)
If you aren't sure, run `df -Th`. Look for the correct disk size and ext3 or ext4 format.
Mount your normal system partition:

sudo mount /dev/sdXY /mnt

If you aren't sure if you mounted the correct partition, once it's mounted run "nautilus /mnt" to inspect the partition. If it is the correct partition, you should see the normal Ubuntu folders such as /bin, /boot, /etc, /home, etc
Example: sudo mount /dev/sda1 /mnt
Note: The partition to mount is normally the partition on which Ubuntu was installed: sda1, sdb5, etc. If you have a separate /boot partition, use the device on which the /boot partition is located. Grub 2 works best when installed in the MBR of the drive to which BIOS boots. Also remember that you mount the partition (including the number) in this step, but you do not include the partition number when you run the "sudo grub-install" command later.
Note: GRUB 2 counts the first drive (X) as "0", but the first partition (Y) as "1"
Only if you have a separate boot partition:

sudo mount /dev/sdXY /mnt/boot

with sdXY being your /boot partition designation.
Reinstall GRUB 2:

sudo grub-install --root-directory=/mnt /dev/sdX

Do NOT include the partition number.
Example: sudo grub-install --root-directory=/mnt /dev/sda
Note: Substitute the device on which Ubuntu was installed - sda, sdb, etc. Do not specify a partition number.
Unmount the partition *:

sudo umount /mnt

* Note: If you mounted a separate /boot partition, unmount it first:
Code:

sudo umount /mnt/boot

Reboot.

sudo shutdown -r now

EDIT: I apologize greatly for my faulty code..I thought I penciled it down right, but look at what that did. I am really sorry about that.

No need to apologize you helped me so very much it worked. You saved me a lot of grief from my wife. Thank you thank you thank you again.

Re: Laptop dead need HELP! (solved praise God!)

I saved you from the fury of a woman? My goodness man, I'm glad I found it when I did!

Jokes aside, it was not a problem. I've been given a lot of help from people such as Vinny, and oshunluvr, snowhog, etc. I figure, since I've been getting a lot of help, I can give help where possible. I knew[to a degree]how to help here. Yes, I goofed up on you, and I still apologize for that. But I managed to get you the correct stuff. It probably saved those guys a lot of time doing the same. Plus, it reinforces what I already know. So things are good. If you see something that you can help in, do so. Thats how these communities are formed. Everyone helps as much as they can.

You didn't get the memo? The one that updated "Hell hath no fury like a woman scorned" to "Hell hath no fury like a woman whose husband can't fix her computer"?

Good job, LinkMaster!
