Hi,I have a dual boot (fedora 14 with windows xp),haven't used my box for around 13-14 months.Yesterday when I started the box,I wasn't able to see the windows os at boot time,how can I log in to window OS.I am able to login to Fedora,as it is the only option that is coming.

below is the output of cfdisk

In fedora, you can check the grub.conf if the Windows OS boot menu is exist. If it still here, you can press any key to chose the boot menu when the fedora 14 boot splash appears, because fedora 14 boot linux as a default choise.

If you can boot Fedora, you should have a /boot/grub/grub.conf file. Check it to see if you have an entry for windows. It would probably be sda1:

title windows xp
root (hd0,0)
chainloader +1

I have changed the boot order and now i am able to login to windows xp only.The problem is that in the boot menu,even after pressing any key the menu doesn't appear and it loads the os which is default.

Now is there anyway I can switch to Fedora as default option.

can you show the boot.ini in xp c: drive it hidden by default.

Are you still using the Fedora Grub to boot both xp and Fedora?
How did you "change the boot order"?
If you are still using the Grub bootloader and don't see a menu, you will need to put a hash mark (#) to the left of the line near the top:

#hiddenmenu

You can do this with a Linux Live CD including Fedora but without knowing how you did whatever you did, it's kind of pointless to get into more detail.

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect

Yes I am still using the Grub bootloader as I haven't changed anything except the default option in the grub.conf which was earlier 0 to 1,and the timeout to 30.

Thanks

Boot your system with a Live Fedora USB or CD. Map yourself to your grub.conf and paste it here.
