By default, fedora installation buat satu grub conf, if there’s 2 or more OS e.g windows XP, gentoo bla bla. unfortunatelly, some ppl akan experience tak leh dual boot. For example dual booting windows xp ngan FC2. yes it’s really a bug. for those yang tatau ler, https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=115980

Default installation grub config(depends go check ur grub.conf and see)

Rootnoverify(hd1,1)
Chainloader +1

tapi tak leh. dems!

Simple fix. no worry! sample test workaround which works on me. Open terminal issue command fdisk -l > partition.txt
Open partition.txt check ur partition windows anda. hda or hdb? Then issue this command sfdisk -d /dev/hdb | sfdisk --no-reread -H255 /dev/hdb

Assume yang hdb tu partition windows anda. check using fdisk -l. dalam some cases kena force. fdisk -l --force then reboot and see. Kalau tak bleh, u need to edit ur grub.conf either in /etc/grub.conf atau /boot/grub/menu1st change the windows line wif this.

title Windows
        map (hd0) (hd1)
        map (hd1) (hd0)
        rootnoverify (hd1,1)
        chainloader +1

Add the 2 line map map (hd0) (hd1) and map (hd1) (hd0), assuming tat ur FC is in the primary hd and windows kat secondary hd. refer to ur default grub made by FC installation. in some cases u need to map the drive, makeactive, force the bios to LBA bla bla!! Personally i recommend dont fdisk /mbr unless u r fcuking idiot. prepare FC rescue disk, paling cikai cari knoppix rescue disk, mana la tau!
