You can (temporarily) edit that (it won't change the files on disc, just
what it's going to use as you boot, now). Or you can go to a command line
interface in GRUB and just type in commands anew.

All things being equal, the primary master drive is /dev/hda and primary
slave is /dev/hdb, then secondary master is /dev/hdc and secondary slave is
/dev/hdc. If both drives are on the same port, your Linux drive is
/dev/hdb. But if it's on the next IDE port, it's /dev/hdc.

GRUB doesn't use /dev/hda style of naming, it uses HD0 - HD4 etc. Counting
the drives that it can find. Zero being the first drive, one being the
next. So, I'd say your root is probably (hd1,0).

The kernel uses /dev/hda style of naming, and yours might need a
root=/dev/hdb3 where mine's got VolGroup entries. Note that this is the
*system* root (/), not the GRUB root (where it boots from). That could be
on any partition. Mine happens to be on hdb3, on one of my systems. It
depends on how many partitions are being used, and what order.

I'd expect your grub.conf file to need to be something like the following,
seeing how the default method for Fedora seems to use Volume Groups:

title Linux
        root (hd1,0)
        kernel vmlinuz-2.6.11-1.35-FC3 ro root=/dev/VolGroup00/LogVol00
        initrd vmlinuz-2.6.11-1.35-FC3.img
