grub2 not found WinXP

kotfantazer · #1 30th March 2012, 05:19 PM

Hello!
I tried to edit config files grub, but it did not help.

Completed: su-c 'grub2-mkconfig-o / boot/grub2/grub.cfg' but this is also did not give any result - grub found two core Fedora, but have not found Windows.

Command sudo update-grub doesn't exist.

How to find Windows? =))

Advantage of advice:

make sure you have os-prober installed.

Code:

su -
(root password)

yum install os-prober

The run the grub2-mkconfig

Code:

su -
(root password)

grub2-mkconfig -o /boot/grub2/grub.cfg

Package os-prober-1.48-2.fc16.i686 already installed and latest version

***DBelton*** · #4 31st March 2012, 01:26 PM

what does the output of grub2-mkconfig -o /boot/grub2/grub.cfg show?

Also, what is it output of fdisk -l

you have to run fdisk as root user.

***DBelton*** · #8 31st March 2012, 01:53 PM

That's interesting... Are you even able to boot Windows XP?

Windows XP usually requires itself to be on the first primary partition of the first hard drive. You have it in a extended partition, with your linux partitions before it on the drive.

That could possibly be your problem, too. I'm not certain if grub2 can pick up a Windows XP install in an extended partition or not, and even if it can, I'm not certain if Windows XP would even boot.

Just for reference, here is what I have on my machine where I dual boot Windows and Fedora.

Code:

Oops! Yes, I noticed that GRUB calls to Windows. But boot is not happening.
I thought that this is the problem with the configuration.
Windows was installed first. And it is run.

Sorry for my English!

***DBelton*** · #10 31st March 2012, 02:09 PM

ok, what does your /boot/grub2/grub.cfg file look like? Can you copy/paste it here?

kotfantazer · #11 31st March 2012, 02:16 PM

Advantage of this advice now. Also did not help.

It's written by me

***DBelton*** · #12 31st March 2012, 02:22 PM

Ok, run

su -c blkid

And note the value it gives you for /dev/sda5 (just the UUID value)

the part you wrote, for your Windows XP.. change it to look like this:

Code:

menuentry "Microsoft Windows XP Professional (on /dev/sda5)" --class windows --class os {
	savedefault
	insmod part_msdos
	insmod ntfs
	set root='(hd0,msdos5)'
	search --no-floppy --fs-uuid --set=root value noted from blkid command above
	drivemap -s (hd0) ${root}
	chainloader +1
}

kotfantazer · #13 31st March 2012, 02:31 PM

ok. change in which file?
/ etc/grub.d/40_custom

or

/ boot/grub2/grub.cfg

***DBelton*** · #14 31st March 2012, 02:37 PM

you can put it into your /boot/grub2/grub.cfg file for now and see if it works for you.

If you run grub2-mkconfig again, it will overwrite the changes, though, so once you figure out what works, then you need to change the /etc/grub.d/40_custom file so that it puts it in when you run grub2-mkconfig.

kotfantazer · #15 31st March 2012, 05:07 PM

Added this:
menuentry "Microsoft Windows XP Professional (on / dev/sda5)" - class windows - class os {
savedefault
insmod part_msdos
insmod ntfs
set root = '(hd0, msdos5)'
search - no-floppy - fs-uuid - set = root B484A45B84A4223A
drivemap-s (hd0) $ {root}
chainloader +1
}
