Reinstalling GRUB Menu

The system is not running knoppix. It's running Redhat linux I think.

You can backup apps? :|

Oh redhat? Well you can call redhat customer support. And yes you can back up youre whole system like in windows.

Well thats making an img.. but restoring the image would leave me with the same no GRUB problem...

Well, no. It will install an operation system, like a clean install, exept that it has all your software and settings. Get it?

I get it.. But I don't get it.. Somethings telling me that won't work though...

well im not sure if i can help you further. Just download a software that does this (too lazy to look for one)

Ok so.

When I run the "dd if=/dev/hda2 of=/linux.bin bs=512 count=1"

I get an error saying " no such file or directory."

Also, noticed you said knoppix partition. I am booting from knoppix on a cd.. I think it's redhat linux on the next partition. I'm not even sure xD.

Edit.

So I noticed when I ran the command it was saying "dd: opening '/dev/hda2' : No such File or directory"

So i figured it was just pointing to the wrong path. I opened up explorer and changed /dev/hda2 to /media/sda2.

When i run the command with /media/sda2 it says "opening /linux.bin': permission denied"

:S

For this method to work Grub must be placed in the Linux root partition and Not the MBR.
Then you run the DD command.

How many partitions do you have on your computer?

How do I do that?

Recovering GRUB after reinstalling Windows

As above, when Windows is reinstalled, the master boot record will be overwritten. This can be avoided by backing up the boot sector, by following the instructions from step 2 in the above section 'Installing Windows After Ubuntu'. An alternative method is to use the Ubuntu LiveCD to reinstall the GRUB boot sector, here are step-by-step instructions, to be run after Windows has been reinstalled:

1. Boot into a LiveCD .....You have an Ubuntu Live CD right?
2. Open a terminal
3. Open the GRUB Command line utility by typing

sudo grub

1. Tell GRUB where your Ubuntu partition is by entering
2. root (hdA,B).... IN YOUR CASE root (hd0,1)...... Ubuntu is on your 1st harddrive 2nd partition

Where 'A' is the hard-drive number, starting at 0, and 'B' is the partition number, starting at 0. For example, if Ubuntu was installed on the second partition of the first hard-drive, the command should be

root (hd0,1).... RUN THIS.....there is a space between ROOT and (

1. Tell GRUB which drive to put the boot sector on

setup (hd0,1)... RUN THIS....... will install GRUB to partition and not MBR.....
there is a space between SETUP and (

If you run...... setup (hdo)....... it will install GRUB to MBR.

1. Leave the GRUB Command line
2. quit..RUN THIS

and reboot. This will not give dual-boot yet.

If this works post back and I will help with the next part. This is the link:
