Fedora Users — Re: Grub working on interactive mode

You need to edit you grub.conf file, put ther three lines below into your /boot/grub/grub.conf, there's some extra 'mantra' in there as well to show you an image as the background, timeouts and other stuff, I've attached mine as an example.

The other important file is /boot/grub/device.map is automatically generated by the grub command, there is a 'nice' way to do but I've forgotten, here's _a_ way to do it:

mv /boot/grub/grub.conf /boot/grub/device.map.backup && echo "quit" | grub --device-map=/boot/grub/device.map

This will give you the device mappings for grub style device names.

Then just fix up your grub.conf and do a `grub-install` and you should be done :)

To save a little confussion, I have FC1 on hdc2, /boot on hdc1 and WinXP on hda2.

Hope that all works for you.

You can try like this

grub> root (hd0,0)
grub> kernel /boot/vmlinuz root=/dev/hda1 ro hdc=ide-scsi rhgb acpi=on

grub> boot

Now you can reconfigure your Linux

Hi! I´m trying to boot my FC1 box and the grub now, instead of opening the screen with options to boot on Win or Linux, it now opens a GRUB prompt with lots of options. I tried several, but could not boot to linux. What should I put on the Grub prompt to get into the box? Regards, Thiago
