I have had Ubuntu 7.04 and Windows 2000 in my very low-end computer (PIII @ 600MHz) since April now. Windows on one HD, Ubuntu on another, and files on one FAT32 HD. Everything has worked fine, selecting the OS you want to boot is fine with GRUB. However today I Changed the processor to a newer (still old) PIII @ 933MHz. Doing this required me to change the motherboard also.

The problem is that now the Windows refuses to boot at all, and Ubuntu cannot load the graphic interface, it boots to ubuntu terminal after error messages.

My questions are:
Is this about GRUB and the new setup? If so, how could it be fixed?

Or is it about something else? If so, tips would be greatly appreciated.

Thanks in advance, ~NU

PS: If you need more info, I am happy to try and provide.

Changing the mobo means that the modules being loaded are not necessarily the correct ones for your new hardware which will obviously cause problems - I reckon you may need to reinstall.

You could try booting from your install disk and doing an Upgrade option to reinstall GRUB - should be available with Ubuntu
There are other ways of doing this but this may be easiest.

Windows will probably boot as well but will also need drivers etc - again better to reinstall.....IMHO

Yeah, I was hoping for another way to get over it, I hate installing windoze, but reinstalling is probably the best solution here.

Thanks for the help anyways!

You almost certainly need to reinstall Windoze. It will overwrite the grub setup, assuming its in the master boot record of the first hard disk. Grub can then be reinstalled from the linux command line. I cant remember whether to use command grub-install,
Details here, or to install grub from grub. (I think the latter is best for you).
Graphics can be restored in Linux by reconfiguring X. There is a command-line program in Puppy that does this. I cant remember its name. Check the Puppy website for it.

Okay, things have changed.

I have already decided to reinstall Windows, but i do not want to reinstall it twice (I did some hardware changing between two computers)

So now the two setups are:

Main one has a new mobo, new HD in which the Windows will be installed, the file HD and the Linux HD. I only have to reinstall the two OSs, all is clear on this computer.

The another one has the old mobo, the old Windows HD and a new file HD. The Windows HD has that little GRUB in it, which only starts, and refuses to load, because the main files are on the linux HD, which isn't in the computer. So currently I cannot start windows on it.
----
Putting the Ubuntu HD in didn't help, because the mobo refuses to comply with an unix disk, wonder why, as it had no problems when I first had it there..
I just want to get the grub out of it, as I will not put two OSs on it.


Hopefully you got all that, thanks in advance!
