Problems with Grub

[Aperez <alfredoj69@gmail.com>]

Hello everybody

I had installed Fedora but I decided to install Debian Sarge. After the 
Sarge installation process I get following messages:

GRUB loading stage1.5
GRUB loading, please wait
Error 18

PC hangs

I tried fdisk /mbr with a win 98 diskette and install sarge again. But 
the same problem occurs

Any suggestion?

Thanks
