[SOLVED] GRUB on wrong disk

[borobudur]

Hi,
my desktop has two disks (A and B). I installed ubuntu on disk A and edubuntu on disk B. With installing edubuntu the start up process reads now from the disk B the grub file.

I wanted to remove the disk B but this isn't possible anymore :-(

How can I change it that the system reads the grub file from disk A ?

Thanks

I reinstalled the whole system :mad:

That's the final solution.
