error: attempt to read or write outside of disk ‘hd0’ [How to Solve]

Introduction

Some situations (such as BIOS limitations or this grub error) may require to create a separate/boot partition at the beginning of the disk and set up Ubuntu to use it

Here’s how to do it easily:

Procedures

Step 1 – boot on Live CD or live USB

Start the computer:

-Linux secure remixlivivecd or liveusb, then select “Try Ubuntu”, and then go directly to Step 3 below

-Or Ubuntu Live CD or live USB, select “Try Ubuntu” and go to step 2 below

Step 2 – install boot repair in a real-time session

After entering the Ubuntu real-time session, install boot repair in this way:

Connect to the Internet

Open the terminal (Ctrl + Alt + T) and type:

sudo add-apt-repository ppa：yannubuntu/boot-repair && sudo apt-get update
sudo apt-get install -y boot-repair

Step 3 – run GParted

Start GParted from any of the following:

-Dash (Ubuntu 11.04 and next): click the Ubuntu logo in the upper left corner of the screen, then type GParted and click the GParted icon that will appear

-Or system – > Management – > GParted menu (Ubuntu 10.04)

-Or type gksudo GParted in the terminal

Step 4 – create a 1GB partition at the beginning of the disk

Through GParted:

-Reduce one of the first partitions of the disk so that creates 1GB (= 1000mib) of free space at the beginning of the disk on which Ubuntu is installed. This free space must be within the first 100GB of the disk (the starting position of the disk at its end must not exceed 100GB). Important: to adjust the size of Windows Vista/7/8 partition, use windows tools instead of GParted

-In this free space, create a 1GB partition with format ext4

-On paper, write down the name of the new 1GB partition. This is usually similar to/dev/ sdxy (x is a letter and Y is a number)

Step 5 – run boot repair

Start boot repair from any of the following:

-Dash (Ubuntu 11.04 and next): click the Ubuntu logo in the upper left corner of the screen, then type boot and click the boot repair icon that will appear

-Or system – > Administration-> Boot repair menu (Ubuntu 10.04)

-Or type boot repair in the terminal

Step 6 – choose the right option

In boot repair:

-Click Advanced Options

-Go to the grub location tab

-Check the “separate/boot partition: sdxy” option (sdxy must be your 1GB partition)

-Click “apply”

-Note the URL that will appear on the paper ( paste. Ubuntu. COM/XXXXXX/)

-Turn off the computer

-Remove Live CD and/or live USB

-Turn on the computer. You should be able to boot to Ubuntu by now

– aLinux-Secure-RemixliveCD or liveUSB, then choose “Try Ubuntu”, then go directly toStep 3 below.

– or a Ubuntu live-CD or live-USB, choose “Try Ubuntu”, then go toStep 2 below.

Step 2 – Install Boot-Repair in the live-session

Once in the Ubuntu live session, installBoot-Repairthis way:

Connect internet

Open a terminal (Ctrl+Alt+T) and type :

sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update

– or System->Administration->gParted menu (Ubuntu 10.04)

– or by typinggksudo gpartedin a terminal

Step 4 – Create a 1GB partition at the start of the disk

Via gParted:

– Reduce one of the first partitions of the disk in order tocreate 1GB (=1000MiB) of free space at the start of the diskwhere Ubuntu is installed. This free space must be locatedinside the first 100GB of the disk(its end must not be located at more than 100GB from the start of the disk). Important: to resize Windows Vista/7/8 partitions, don’t use gParted but Windows tools instead.

– In this free space, create a1GB partition formatted in EXT4.

– On a paper, note the name of this new 1GB partition. This is generally something like /dev/sdXY(X is a letter, Y is a number).

Step 5 – Run Boot-Repair

Launch Boot-Repair from either:

– the Dash (Ubuntu 11.04 and next): click the Ubuntu logo in the top-left corner of the screen, then typebootand click on theBoot-Repairicon that will appear.
