after that i did

Code:

grub-install --recheck /dev/hda

Installation finished. No error reported
This is contents of the device map /boot/grub/device.map
check if this is correct or not. if any of the lines is incorrect, fix it and re-run the script 'grub-install'.

(fd0)    /dev/fd0
(hd0)    /dev/hda
(hd1)    /dev/hdd

then i typed this to check if they are correct

Code:

cat /boot/grub/device.map

(fd0)    /dev/fd0
(hd0)    /dev/hda
(hd1)    /dev/hdd

then i rebooted i got same error

Code:

GRUB Loading stage 1.5.

here is the config file again

Which OS is giving you the error? FC5 or Windows?

gujuboy · 05-02-2006, 09:55 PM

its error i get i cant boot in any of OS.

billymayday · 05-02-2006, 10:03 PM

I believe 21 means Selected disk does not exist.

Since Grub uses it's own drive designations (you've listed them yourself), shouldn't it read something like:

default=1
timeout=30
splashimage=(hd1,4)/boot/grub/splash.xpm.gz
hiddenmenu
title Fedora Core (2.6.15-1.2054_FC5)
root (hd1,4)
kernel /boot/vmlinuz-2.6.15-1.2054_FC5 ro root=LABEL=/ rhgb quiet
initrd /boot/initrd-2.6.15-1.2054_FC5.img
title Windows XP Prfessional
rootnoverify (hd0,0)
chainloader +1

?

got the same error

billymayday · 05-02-2006, 10:15 PM

Not my area, but what I'd do is comment out the linux load (and the splash) and see if windows boots.

Then I'd do some grub reading and check that hdd5 equals hd1,4 and not hd1,5, hd1,2 or hd1,3.

My money's on hd1,2, but as I said, not my area

gujuboy · 05-02-2006, 10:20 PM

anyone else have any solution for this?

billymayday · 05-02-2006, 10:22 PM

Didn't work?

billymayday · 05-02-2006, 10:31 PM

From the manual page:

The device syntax used in GRUB is a wee bit different from what you may have seen before in your operating system(s), and you need to know it so that you can specify a drive/partition.

Look at the following examples and explanations:

(fd0)

First of all, GRUB requires that the device name be enclosed with `(' and `)'. The `fd' part means that it is a floppy disk. The number `0' is the drive number, which is counted from zero. This expression means that GRUB will use the whole floppy disk.

(hd0,1)

Here, `hd' means it is a hard disk drive. The first integer `0' indicates the drive number, that is, the first hard disk, while the second integer, `1', indicates the partition number (or the pc slice number in the BSD terminology). Once again, please note that the partition numbers are counted from zero, not from one. This expression means the second partition of the first hard disk drive. In this case, GRUB uses one partition of the disk, instead of the whole disk.

(hd0,4)

This specifies the first extended partition of the first hard disk drive. Note that the partition numbers for extended partitions are counted from `4', regardless of the actual number of primary partitions on your hard disk

gujuboy · 05-02-2006, 10:39 PM

From where grub should be reading?

here where i have installed Windows XP

Code:

/dev/hda2                3826     14946     89329432+      f        W95 Ext'd (LBA)

here where i have installed FC 5

Code:

/dev/hdd5                3145      6169     24298281       83       Linux

billymayday · 05-02-2006, 10:47 PM

I'd have thougt hda,1 for Windows (or is it extended in which case it would be hda,4 if hda1 is primary?). Is hdd5 a primary or extended partition?

lol i m confused now.. i dontknow where i have installed windows in .. all i know is windows in Disk /dev/hda: 122.9 GB, 122942324736 bytes

billymayday · 05-02-2006, 11:18 PM

It's the partions you need to worry aout, not the drives. You already know the drives from the original post.

And yes, I think grub is confusing
