GRUB

[zerohourkill]

Where should i install GRUB(i mean partition) so if i want to delete distro i dunt have to clean up my whole Hard Disk, but only Linux partition. I once deleted Suse, and then i couldnt boot in windows xp, it said that computer cannot find Grub. So i just emptied my whole hard disk, cuz i wasnt able to boot or reinstall windows

I think if want to use grub then it will take over on mbr,
else if u do not want to do this then istall it to first linux sector and prepare a boot disk,
coz then u`ll be needing this every time u need to boot into ur linux mexhine,

Secondly, it takes about 5min to repaire ur MBR after deleting linux partetion from ur HDD, so it`s better to install it there nd ther repaire ur MBR.

You even don't need to make boot floppy.
download XOSL, and you can manage booting

grub is a very powerfull boot loader and does away with the need of softwares like XOSL. On my system Grub gives you the option to boot into
Fedora
Gentoo
Slackware
Win XP
Solaris 10

So grub installed on the mbr is the best option.

Its easy .install it on the first sector of mbr.When you don`t want the linux.Use a boot floppy for windows ar a bootable cd.then run
fdisk
set the active partition to your windows partition and then do
fdisk/mbr to remove grub.

@pradeep_chauhan
I had installed suse9.1 on hda10 partition.Then I installed mandrake 10.1 by deleting a partition on windows so the suse partition got renamed to hda9 and now mandrake is installed on hda10.I also have winxp.How do I triple boot the system.i.e my grub shold show
1.winxp
2.suse 9.1
3.mandrake10.1

I know I have to edit the grub file biut i can`t find it in /boot .By the way the present grub show windows and mandrake

 

[pradeep_chauhan]

Do you have a seperate / boot partition ? I think there is a seperate boot partition so make a dir at any place say /mydir and
# mount /dev/hda8 /mydir
now
#vi /mydir/grub/grub.conf

here you have to edit the details as per the new partitions.

If this does not work post the partitions you have on your hdd.

 

[vignesh]

there is no hda8 that is the swap partition.hda9 is mandrake and suse is in hda10 but used to be in hda9 before mandrake was installed.

 

[vignesh]

there is no hda8 that is the swap partition.hda9 is mandrake and suse is in hda10 but used to be in hda9 before mandrake was installed./boot partition I only know there is /boot in the root directory where the grub.conf is present or are you talking about the /boot type of filesystem.

 

[pradeep_chauhan]

Please post all the partitions on your disk. Till now i know
hda8 = swap
hda9 = linux 1
hda10 = linux2

also you say that in hda9/boot there is grub.conf then edit it whats the problem?

 

[vignesh]

there is no grub.conf in hda9 I am asking you where it is in mandrake. there are 4 windows partitions hda1,5,6,7.

 

[pradeep_chauhan]

When you start your system Do you get the grub splash / choice screen? If yes press the key to edit the entry and see where root= XXXXXXX points to thats the location where you will find the kernel and in the same location within /grub will be grub.conf.
aslo boot in linux do a
# fdisk /dev/hda

then give command to see partitions p
pl post the output you get.

 

[vignesh]

the current choices are mandrake and windows in mandrake`s boot screen is it same as grub i don`t know.

The output of the fdisk command of my disk is as below


[root@pebble pradeep]# fdisk /dev/sda

The number of cylinders for this disk is set to 19457.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

[root@pebble pradeep]#

In the listing the partition /dev/sda6 is the /boot partition and when i mount it you will see the grub.conf file
[root@pebble pradeep]# mount /dev/sda6 /mydir/

[root@pebble pradeep]# ls /mydir/grub/
device.map ffs_stage1_5 menu.lst splash.xpm.gz vstafs_stage1_5
e2fs_stage1_5 grub.conf minix_stage1_5 stage1 xfs_stage1_5
fat_stage1_5 jfs_stage1_5 reiserfs_stage1_5 stage2
[root@pebble pradeep]#

I hope this helps

 

[vignesh]

Do we have to have a /boot partition along with swap and the / partition ?
I cant understand anything there.

 

[pradeep_chauhan]

Why dont you post your hdd info? as i said before and shown above doa fdisk /dev/hda and then select option p the resulting o/p please post it. Without this info its not possible to go any further.

 

[vignesh]

hda1 =winxp
hda5 ,hda6,hda7 are fat32 partitions
hda8 = swap
hda9 = linux 1
hda10 = linux2

the present grub is
mandrake default one showing linux and windows

 

[vignesh]

hda1 =winxp
hda5 ,hda6,hda7 are fat32 partitions
hda8 = swap
hda9 = suse but was before in hda10 since I had a extra fat32 partition.which I removed when i installed mandrake
hda10 = mandrake

the present grub is
mandrake default one showing linux and windows

 

[pradeep_chauhan]

Boot into linux, ithink you will be able to boot in linux 2 and check for grub in filr in /boot/grub/
If not there the only other place is as follows
make a dir /mydir and mount the linux 1 partition on to it
#mount /dev/hda6 /mydir
then go to /mydir/boot/grub/
here you will find the file.
