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
