File partition problems with Fedora Core 4 / Windows XP dual-boot installation
I've been having some difficulty getting Grub to see my Windows NTFS partition after I used partition magic to resize it and then DiskDruid as part of the Fedora install.
Grub wasn't seeing the Windows partition.
Disk /dev/sda: 160.0 GB, 160000000000 bytes 255 heads, 63 sectors/track, 19452 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 1 7 56196 6 FAT16 /dev/sda2 8 9729 78091965 7 HPFS/NTFS /dev/sda3 * 9730 19388 77585917+ 83 Linux /dev/sda4 19389 19452 514080 82 Linux swap / Solaris
This was because the Windows partition (/dev/sda2) was flagged as hidden.
Grub therefore didn't write this into the grub.conf file on installation
I used parted to switch the hidden setting off:

I then changed the /boot/grub/grub.conf file as follows and it all now works:
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You do not have a /boot partition. This means that
# all kernel and initrd paths are relative to /, eg.
# root (hd0,2)
# kernel /boot/vmlinuz-version ro root=/dev/sda3
# initrd /boot/initrd-version.img
#boot=/dev/sda3

This was quite useful for explaining the syntax in the grub.conf file:
