GRUB has installed itself over Windows


I have a major problem.

I've used LILO as a boot loader for some time (and still do), and when I changed kernel yesterday grub somehow got installed on my Windows partision. This makes it as if I select to boot Windows I get into grub, wher I cen select Windows to get into GRUB and so on (or any of my kernels to get into linux)

This is a major problem as I have to use Windows to be able to pay my rent. Which I'm supposed to do today.

Is there any easy way to get back the windows partision. (a windows boot disk does not recognize the format of the former Windows drive so I can't get into windows, and I don't want to reinstall as it would probably mean that I have to reformat the Windows partsion just as I'm starting to get the installation to work without crashing moe then 50% of the seesions)

Any help at all?

When you get to the GRUB boot screen you say you choose Windows. Does this boot Windows?? If so then you just need to change your grub boot file. If you can't boot into windows through grub then there is a bigger problem lurking.

When you changed kernels did you keep an option to boot into your old one?? What distro you are using might be helpful for someone else to help you.

I've solved the problem. Figuring out what I had done helped alot.

I remember that I was thinking about changing to GRUB yesterday, but changed my mind. Anyway I had already run the command to install GRUB (or so I thought), so I just did a LILO -v to skip it.

Now I realized that I must have run `grub-install /dev/hdc[b]1]/b]` instead of `grub-install /dev/hdc` and as a result of not knowing what I did I replaced the boot sector of the Windows partision with GRUB.

To answer rberry88's questions: This resulted in nothing at first when I were just jumping between differen kernels yesterday (yes, I kept my old kernel), but when I today were going to start Windows to pay my rent (as my bank doesn't support Linux ) I got into GRUB. grub had the option to boot my kernels and Windows, but the option Windows just started GRUB again, and I could keep that loop on for infinity. Booting linux from GRUB worked just fine, so I got here and posted for help. Well, actually first I tried to boot by CD rom and SYS c: but it wouldn't recognize the file system.

As I did want to fix this problem as sson as possible I tried to find any help already available on it, and finaly I found this page after half an hour.

So I did
dd if=/dev/zero of=/dev/hdc1 bs=512 count=1
booted from the CD again, and then did
sys a: c:

And it all worked.

Cool, glad to see you got it worked out. Booting issues and compiling new kernels seem to give me the biggest stress tests but it's all worth it once all is solved.
