Grub just displaying "GRUB"

[Andre Schlink]

Hi,

i've installed FC4 on a box with Win2000 on an SATA-Drive. I Would like to
boot FC4 using the Windows Bootloader (its a company PC). After installing
FC4 on a separate HD i recognized that the DVD drive was jumpered as master
and the HD i installed Linux on was jumpered slave. I've changed the jumper
settings and booted using the rescue CD in order to adapt /etc/fstab and
reinstalled grub with --recheck to get the device.map corrected.
Grub is installed to the root partition /dev/hda1 and the bootsector is
added to the windows bootloader:

grub-install --recheck /dev/hda1
dd if=/dev/hda1 bs=512 count=1 of=bootsector_fc4

When i try to start linux grub just displays "GRUB" and nothing else happens.
Installing grub to a floppy gives exactly the same error.

Here's my grub.conf:

#boot=/dev/hda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
#hiddenmenu
title Fedora Core (2.6.13-1.1352_FC4smp)
	root (hd0,0)
	kernel /boot/vmlinuz-2.6.13-1.1532_FC4smp ro root=LABEL=/ vga=794
	initrd /boot/initrd-2.6.13-1.1532_FC4smp.img
title Fedora Core (2.6.13-1.1352_FC4)
	root (hd0,0)
	kernel /boot/vmlinuz-2.6.13-1.1532_FC4 ro root=LABEL=/ vga=794
	initrd /boot/initrd-2.6.13-1.1532_FC4.img


device.map:

(fd0)	/dev/fd0
(hd0)	/dev/hda
(hd1)	/dev/sda

mounts:

/dev/hda1 on / type ext3 (rw,defaults)
/dev/hda2 on /home type ext3 (rw,defaults)
/dev/hda8 on /opt type ext3 (rw,defaults)
/dev/proc on /proc type proc (rw,defaults)
/dev/sys on /sys type sysfs (rw,defaults)
/dev/hda6 on /tmp type ext3 (rw,defaults)
/dev/hda3 on /usr type ext3 (rw,defaults)
/dev/hda5 on /var type ext3 (rw,defaults)

The SATA HD is recognized as a SCSI-drive? Is that ok?

I looked through grub man page but found nothing in the truobleshooting section.
Does anyone have a clue what i've done wrong?

Tnx, Andre
