I formatted my HD by misttake losing all partitions including manufactture data and I am now faced by the grub rescue prompt. I was running Windows 7 alongside Ubuntu andwonder how do I get somthing going on my notebook. I've got a Windows 7 and Ubuntu disk of a previous version although I had upgaded to the latest version of Ubintu online. Please help...

Do you want to start over (fresh) and duel boot Windows and Linux?
Do you want to access your old data files?

Please give more information so that we can help you even more.

I wamt to start over for I believe there is no other choice. Do not know where to begin. I do welcome your input...

If you don't have any data you want to try to retrieve, just boot the windows 7 CD/DVD, set the BIOS to boot from the CD/DVD drive and boot windows and install it. Then repeat with Ubuntu.

If you have data, you can try to find/save it using testdisk, download from the link below. You might try an online search for using it before you try so you have some background knowledge.

Thank you. But my BIOS by defaught looks for the boot sequence on rhe CD drive yet I am still taken back to the grub rescue pr ompt. I think it migjt be the result of losing the data the manufacturer of my machine put on a partition...

The grub rescue promp gave me the error message no such partition on my attempt to load a Windows 7 cd?

upon entering ls after the prompt I am getting (hd0) (hd0,msdos1) (hd1) (hd1,msdos1)? I deleled all partttions on my HD except for the largest one by mistake in anticipation of starting over with a clean system. I think it was ACER's partititioñ that screwed me up...

Grub is on the hard drive, only. If you are getting the grub rescue prompt, you are going to the hard drive and your BIOS either isn't set right or is malfunctioning. You might check for additional options in the BIOS because it is not possible for you to get anything related to grub unless you are going to the hard drive.

Which simply means your grub entry is pointing to the wrong partition which is probably explained in your last post. Your last post indicates two hard drives??

You should not see a grub rescue prompt if you are booting from the windows or any other bootable CD/DVD. I doubt deleting Acers partition caused the problem you have. If you have a windows installation CD and your BIOS set to boot from CD as first boot priority, you should see the CD boot. If it is skipping that, your BIOS may not be configured properly, the cables on the CD drive may be loose or the CD drive may be bad.

Load you ubuntu cd & post output of to see wha is left after attempted reformat,maybe you didn't erase /home

I have only one HD. The ls display confused me too. I set the BIOS to defaught except 4 the CD ROM that I put in the first position. The problem persists. I will also take a look at remaining suggestions...

Can you test with a different bootable CD (e.g. an Ubuntu one)? It sounds like there may be something wrong with the Windows disk if the BIOS will not boot it.

If you want to a dual boot hard drive then you will need to load on Windows first.
Before you do all of this you will need to wipe grub off of your hard drive first.
Download DBAN (Darik's Boot And Nuke):
http://sourceforge.net/projects/dban...6.iso/download

This link is an automatic download so you do not have to do anything except wait.

(Burn this file to a blank disc and boot the computer with it. Do not unzip this file.)

What you need to do with this very good piece of software is to first load it into your machine
(make sure your computer is set to load CD/DVD drive first) and then turn off your computer (this wipes/clears all of your ram of any data), wait 10 seconds and then start up your computer/laptop/notebook. When DBAN has booted (you might have to wait a few seconds/minutes for it to boot) just select the default section (read carefully what it says on your screen).
You need to press your keyboard key marked "F10" for it to start and wipe your drive. You will need to wait at least 3 to 4 hours or at least until it gets to 4 or 5 percent. When you have got to this mark then just do a full shutdown of your computer and wait for 10 seconds (this wipes/clears all of your ram of any data). When you boot up your computer, your computer should ask/tell you that you have "no system" installed, this is a good sign, now you can load on your system disk of either first Windows (if you want a dual system with Linux) or just load on any linux disk, as in your case Ubuntu.

If you need any more assistance just call/post on here.
