grub doesn't show boot menu, just goes directly into Linux ?
 
Fedora 13 = Primary Master drive
Windows XP = Secondary Master drive

I installed Fedora 13 from a cd.
Here's my fdisk:
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

Disk /dev/dm-0 doesn't contain a valid partition table

Disk /dev/dm-1: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

Disk /dev/dm-1 doesn't contain a valid partition table

Disk /dev/dm-2: 28.2 GB, 28152168448 bytes
255 heads, 63 sectors/track, 3422 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

Disk /dev/dm-2 doesn't contain a valid partition table

Here's my /boot/grub/grub.conf:
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.

initrd /initramfs-2.6.33.6-147.2.4.fc13.i686.img

my grub/menu.lst is the same as /boot/grub.grub.conf

Thanks.

Change the timeout value and comment out the hiddenmenu line:

Code:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/mapper/vg_bryan-lv_root
# initrd /initrd-[generic-]version.img
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
#hiddenmenu
title Fedora (2.6.33.6-147.2.4.fc13.i686)
root (hd0,0)
kernel /vmlinuz-2.6.33.6-147.2.4.fc13.i686 ro root=/dev/mapper/vg_bryan-lv_root rd_LVM_LV=vg_bryan/lv_root rd_LVM_LV=vg_bryan/lv_swap rd_NO_LUKS rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us rhgb quiet
initrd /initramfs-2.6.33.6-147.2.4.fc13.i686.img
title Windows XP
rootnoverify (hd0,1)

See if that does it. :)

Agree with brucehinrichs and the menu.lst file you see is a link to the grub.conf file

trien27 08-15-2010 01:07 PM

Thanks, Bruce.
Changing the timeout and commenting out the hiddenmenu works.

Last time I got the grub menu, but when I went to Windows XP, there's an Error 13. Hope I don't get it now.

I will try to get into Windows XP now and see what happens.

New problem:
Using Grub menu doesn't boot into Windows XP, clicking on Windows XP just gets a blank screen, then gets me back to the Grub dualboot menu, not Windows XP? Using F12 at the splash screen and selecting Primary Slave Drive does work and boots into Windows XP. Should I use mapping/remapping?

Thanks.

DrLove73 08-15-2010 03:48 PM

You are missing
Code:

chainloader +1
at the bottom of the file, below
Quote:

title Windows XP
rootnoverify (hd0,1)

trien27 08-15-2010 09:49 PM

Now I get the grub menu with WinXP, but when I click and tried to load it, there's an Error 13: Invalid or unsupported executable format. I have no idea what else could be wrong. I already added the line

chainloader +1

but still get this problem.

Thanks.

DrLove73 08-16-2010 03:35 AM

UuuuPSsss, I missed your XP is on the slave drive (top of the first post). In that case you have to use
Quote:

rootnoverify (hd1,0)
or maybe
Quote:

rootnoverify (hd1,1)
(I do not use dual boot).

If this does not help. thy adding from this:

Quote:

title Windows XP
map (hd0,0) (hd1,0)
map (hd1,0) (hd0,0)
rootnoverify (hd1,0)
makeactive
chainloader +1

or

title Windows XP
root (hd1,0)
savedefault
makeactive
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1

trien27 08-23-2010 08:55 PM

Tried this:
title Windows XP
map (hd0,0) (hd1,0)
map (hd1,0) (hd0,0)
rootnoverify (hd1,0)
makeactive
chainloader +1

but I get Error 21: Selected disk does not exist.

I'll try:
title Windows XP
root (hd1,0)
savedefault
makeactive
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1

later and see what happens.

trien27 08-25-2010 06:43 PM

I tried:
title Windows XP
root (hd1,0)
savedefault
makeactive
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1

And now:
I get Error 21: The selected hard drive does not exist[Windows XP hard drive: Primary Slave drive],
plus
I get all three OSes selections: old version of Fedora, new version of Fedora & Windows XP.

DrLove73 08-26-2010 10:28 AM

What about clean code like this:
Code:

title Windows XP
rootnoverify (hd1,0)
chainloader +1

or
Code:

title Windows XP
rootnoverify (hd1,0)
makeactive
chainloader +1

maybe those swaps do something to it.

One other thing crossed my mind. Take a look at /boot/grub/device.map file. I believe you need one extra row for "hd1". Since you added HDD later, grub might not have it in device map file and even my previos examples might work out of the box after you fix device.map file.

trien27 09-06-2010 04:54 PM

tried the rest of the posts, but none worked: Everything says "Error 21: The selected hard drive does not exist"

Larry Webb 09-06-2010 08:12 PM

Sorry did not see it was marked solved.

trien27 09-07-2010 05:57 AM

I initially thought the problem was solved. I kind of did things too quickly. It still is NOT solved.

Larry Webb 09-07-2010 06:25 AM

I have read the posts and I am confused. In fedora from terminal as root run command fdisk -l and post the results. Your original grub menu has XP on the second partition of the primary drive but above you say it is on slave.
