Post How to reboot into Fedora after installed dual OS


Hello,

I already have XP, I installed Fedora to a partition on another hard disk to make it dual OS. During installation, I choose XP for default OS in boot loader.

Now the problem it only reboot into XP, I am not able to choose which OS boot.

Can somebody please help.

Hello,

What version of Fedora did you install? Most likely you installed grub, but I just want to verify. What you can do is use the Fedora disc that you burned to run a rescue, or live, version, and you can mount your /boot partition and edit your settings. The file you need to edit is /boot/grub/grub.conf.
Let us know if you have any other quesitons.

ok, so you have 2 disks, a Windows one and a linux one.
Your bios keeps booting Windows because installing linux on a second disk does not tell the bios to change which disk is booted.
A solution for you could be to change which disk is booted from by going into the bios.
Then if you can boot into Linux this way, you could edit your /etc/grub.conf file to have a Windows entry that goes to disk one.
Please confirm this works, and if you need further help

Thanks for seeing that, I just woke up. In all honesty, the OP just has to make the secondary hard drive the primary drive, and that's it, due to Fedora most likely seeing windows in the first place. Don't quote me on that, but I am pretty sure of that.

Thank you for reply.

Yes, you are right, This is the problem . I went to bio, unfortunately, not able to set bio to boot from the hard drive with Linux. Because it is a ATA(PATA) hard drive. My PC only have SATA port, so I installed this ATA drive using the parallel cable for the CD-ROM. I could not find any ATA drive in use in Bio, although I was able to read and write on this drive in windows and Fedora was already installed on this drive by using installing DVD. I could not find a why to identify this ATA drive in bio.

I don't not know what to do, maybe I should get one more SATA drive and reinstall Linux.

I appreciate you help.

Jason

If you can't set your Fedora hard drive to first boot priority, you could try installing Grub to the mbr of your xp disk. If you don't want to do that, you can modify the xp bootloader to boot Fedora. It's a little more convoluted. Google "boot Linux from xp with boot.ini" and you should find a number of sites explaining this. Here's one:
