Installing ubuntu on acer x483 but installation stopped and this is what i see Udevd[261]: '/sbin/blkid -o udev -p /dev/sdb'[3102]terminated by signal 9 ( killed)

You could copy the contents from the external drive to the internal one. Boot from an external CD or DVD with the Ubuntu installation image on it. Doing so will allow you to write over the internal drive. Learn the dd command (start with "man dd" from your Ubuntu terminal window. An example might be "dd if=/dev/sdb of=/dev/sda"

"if" is short for "input file", but can represent the whole device (drive), which is what you want. "of" is short for "output file". You can use Ubuntu's Disk Utility to examine all your drives and figure out which one is which.

This is a very powerful command and nothing else I can think of can wipe out a disk you meant to keep any faster or more thoroughly, so be very sure you figure out which (sda sdb, and so on) is input and which is output. The "dd" command produces no output until it's done, just quietly working away on gigabytes as ordered.

Yes you can resize your drive later, before installing ubuntu on the same drive with another operateing system you need to defrag the existing drive, and then resize the partition and then install the ubuntu.

Your installation medium may be corrupted. Try downloading Ubuntu again and burn it to disc or use Linux Live (Google it) to load it onto a USB drive to boot from. Once you do that try reinstalling it. Make sure you download the latest version, either 12.04 LTS or 13.10 (currently latest as of Nov 10th). A new version is released every 6 months and a new LTS is released every 2 years. Version number signifies the year (12 for 2012, 13 for 2013) and Month.

You will need an Ubuntu Live boot CD, you can download from ubuntu's site. Burn to disc and Boot to it on your laptop.

• Once booted, select Try Ubuntu without installing.
• Open a terminal (ctrl + alt + t)
• type sudo fdisk -l
• This will show all your partitions, your main part should be the biggest usually sda1
• Type sudo mkdir /media/sda1
• Type sudo mount /dev/sda1 /media/sda1
• Now Type sudo chroot /media/sda1 to change to your disks context
• Now enter passwd <username> where <username is your login name, remember it is case sensitive.
• Now enter a new password twice.
• Now remove the ubuntu disc and reboot. Your password should now be the new one you created.

Take your Sanyo back to Linux box, hook up the USB cable, and then mount it.

Copy the files that you want to keep on to the $HOME directory on Linux.

Next, from a terminal, run
sudo fdisk -l

to display all the mounted filesystems on the computer.

It might be /dev/sdb1, or /dev/sdc1 You should be able to pick out the M3000 as its hard disk size is 6.0 GB. Let's assume that the USB drive is on /dev/sdb1

Re-run the fdisk command.

sudo fdisk /dev/sdb

(press m to get the help menu).

Recommend that you choose d to delete a partition,
then n to create a new partition
when asked about the code for the new partition, use b -- this corresponds to Windows 95 FAT32 file system.

Don't forget w to write the new partition definition out to the USB drive.
Lastly q to quit fdisk.

Once you exit fdisk, remount the M3000 and make sure that you copy your files back on to it.

All Linux and Windows systems should be able to recognize your drive now.

Its GRand Unified Bootloader used in Linux OS.
Normally you get this error when GRUB is not able recognise the partition from which you are trying to boot the system. Make sure the boot partition on your system is recognisable by GRUB (such as EXT3).

You can try to restore the GRUB using the LIVE CD

1. Boot From Live CD
2. Open Terminal Window
3. type >sudo grub
4. then type : find /boot/grub/stage1
5. you'll get something like: (hd0, 1)
6. then type : >root (hd0, 1)
7. type: > setup (hd0)
8. >quit
9. >exit

Remove the Live CD and reboot the system.


Please let me know if you need any further assistance.


Thank you for choosing Fixya

Here you go:

Download the Ubuntu Live ISO (if you dont have it already) and burn it to CD
Restart your computer (booting from the Ubuntu Live CD)
Insert a 1GB or larger USB flash drive
Open a terminal window and type sudo su
Now type fdisk -l to list available drives/partitions (note which device is your flash drive Example: /dev/sdb). Throughout this tutorial, replace all instances of x with your flash drive letter. For example, if your flash drive is sdb, replace x with b.
Type umount /dev/sdx1
Type fdisk /dev/sdx 
type p to show the existing partition and d to delete it
type p again to show any remaining partitions (if partitions exist, repeat the previous step)
type n to make a new partition
type p for primary partition 
type 1 to make this the first partition
hit enter to use the default 1st cylinder
type +750M to set the partition size
type a to make this partition active
type 1 to select partition 1
type t to change the partition filesystem
type 6 to select the fat16 file system
type n to make another new partition
type p for primary partition 
type 2 to make this the second partition
hit enter to use the default cylinder
hit enter again to use the default last cylinder
type w to write the new partition table
Type umount /dev/sdx1 to unmount the partition
Type mkfs.vfat -F 16 -n usb /dev/sdx1 to format the first partition

"Alternately you can try mkfs.vfat -F 32 -n usb /dev/sdx1 (doesn't always work)"
Type umount /dev/sdx2 to ensure the partition is unmounted
Type mkfs.ext2 -b 4096 -L casper-rw /dev/sdx2 to format the second partition
Remove and Re-insert your flash drive
Back at the terminal, type sudo apt-get install syslinux mtools
Type syslinux -sf /dev/sdx1
Restart your computer, remove the CD and boot back into Windows

Using Windows to prepare and move the files to the USB Stick:
Create a folder named USB on your computer
Download UBconvert.zip using this link - http://www.pendrivelinux.com/downloads/UBconvert.zip
Now, extract the files to the USB folder
Move the Ubuntu  ISO downloaded earlier to the USB folder
Click fixu.bat from the USB folder (follow on screen instructions)
Move all files from the ubuntu directory to your memory stick
Reboot your computer and set your system BIOS to boot from USB-HDD or USB-ZIP. Also set the "Hard Disk Boot Priority" if necessary.

You should now be booting into Ubuntu Linux from your USB drive!

Use apt-get from the terminal to install the ntfsprogs package - sudo apt-get install ntfsprogs

Then you can use the tool ntfsfix from the terminal to attempt to repair a ntfs partition.

Example:
* unmount the drive if it's mounted already
sudo umount /dev/sda1 - read below for device naming info
then type: sudo ntfsfix /dev/sda1

Note:
A typical home pc or laptop has 2 or 4 IDE channels as follows:

• ide0 = primary
• ide1 = secondary
• ide2 = tertiary
• ide3 = quaternary

For example:

• ide0 = primary master = hda
• ide1 = primary slave = hdb
• ide2 = secondary master = hdc
• ide3 = secondary slave = hdd
• sata0 = 1st sata device = sda
• sata1 = 2nd sata device = sdb
  

and so on...
SCSI & SATA devices are listed as devices sda, sdb, sdc, sdd, sde, sdf, etc. in the /dev directory. Similarly, partitions on these disks can range from 1 to 16 and are also in the /dev directory.
Now each hard drive has 4 primary partitions (limit of PC x86 architecture). First partition is denoted by number 1. For example:

• First partition : /dev/hda1
• Second partition : /dev/hda2
• Third partition : /dev/hda3
• Fourth partition : /dev/hda4
• sata0 device, 1st partition: /dev/sda1
• sata1 device, 1st partition: /dev/sdb1

And so on.
You can run command fdisk -l (lowercase L) to display a list of partitions:

WARNING! These examples may result in data loss. Use fdisk command with caution as it can manipulate / overwrite your partition table.

You need to get into bios to change the boot order. You can usually get into bios by tapping F12, esc, or whatever depending on who wrote your bios. Once you get into bios, you should see something like change boot order somewhere. If you don't know where it is then just keep scanning each page and you will find it. It will be called something "boot order". Use the directions on screen to change it to whatever drive you desire and you should be good to go. If you can't do it then write back and let me know.
