Friends,

my dell laptop configuration is

dell inspiron 14 N4010

3gb,320

core i3

windows 7 home premium

      I have tried almost all versions of ubuntu after 9.04 release.but still my problem is tolerated only by the 9.04 version.Every time when they make a release i hope oh it might solve my problem..the problem is that when ubuntu has been installed it works fine until I get into windows and restart from windows.it shows error containing the message "no module found","Please enter any key to exit" , "no operating system found".i have given a seperrate partition of 20GB(sda6) for ubuntu.I have searched so many solutions.I would like to install ubuntu ultimate edition Lucid Lynx since it contains all the packages that I needed.

        yesterday, I saw a reply post in ubuntu forum.

its like this..

sudo grub

>root (hd0,0)

>setup (hd0)

>quit

i got an error that the device can't be mounted.

i don't know the actual sectors from where it boots...

it shows "Grub loading stage 1.5.."etc..

i have tried the find command also.it also shows error.

when i take the ubuntu 9.04 from grub it shows Boot from (hd0,5)..etc.. but when I install other versions its default sector for boot loader installation is hd0.should I change that?i heard that only dell and hp is having this problem.every time a new release comes i hope either ubuntu or dell will fix this problem.it becomes just a hope!! Every time I return back to 9.04 itself.Fortunately its stable every time!!.

I have read somewhere that Data safeLocal backup in dell overwrites the MBR, that's why this problem occurs.but i don't like to uninstall it, because its a great tool provided by dell so i tolerates my problem..

    I'm  doing my b.tech  course and i like to recommend all my friends to buy dell because of its customer support.i hope anyone will give me the actual procedure that i should follow.Also I want to know why all these problems comes,means technically what is happening in the disk sectors.please give me the details.

Thanks in advance..
