Hie,I have just switched to Ubuntu,and have installed Ubuntu 13.10 along with windows 7.At installation time i just gave 15gb to Ubuntu,later on i decided to give my one of partition E:/ to Ubuntu ,so deleted it and formatted it to ext4 through some disk application named "Disks" in Ubuntu.But this suddenly creates a lot problem to me.

  1. Formatted partition is not being mounted. and prompt with following lines appear:

    Error creating partition on /dev/sda:
     Command-line `parted-align optimal-script "/dev/sda" mkpart logical ext2 384777Mib 479045091327b"exited with non zero exit status 1:
    Error:You requested a partition from 403GB to 479GB.
     The closest location we can manage is 403GB to 479GB.(udisk-error-quark,0)
  2. When i rebooted system i have following error:

    Filesystem unknown
    entering in rescue mode
    grub rescue>:

    Which i solved with following commands

    set prefix=(hd0,msdos7)/boot/grub
    set root=(hd0,msdos7)
    insmod normal
  3. But now every time i boot system i have to type these commands manually.

Somebody help me out .Please!

Once you have booted using the commands

set prefix=(hd0,msdos7)/boot/grub
set root=(hd0,msdos7)
insmod normal

open a terminal using (Ctrl+Alt+t) and type:

sudo update-grub

and enter your password. This will update the partitions and inform grub which partitions to search for while booting.

That is working absolutely fine with grub problem, :) but Is there anyway of my mounting error?(Problem 1) I'm hopeless in that .. – Neha Mar 30 '14 at 8:35
You should probably post it as a different question, you may get a better response. – i08in Mar 30 '14 at 8:36
