Dual Boot

srimaya_rath · 15-01-2007, 10:13 AM

Hi Guys,

1. Initially I had only Red Hat Linux 9 was installed in my computer. Yesterday I installed WIN - XP Professional along with Red Hat Linux. But the dual boot prompt is not showing. It's directly going to WIN - XP when I'm booting. I want to use Linux also. Please guide me how to get that dual boot prompt.

2. I'm having a 320 GB HDD. I've not fitted it to my computer. Will it slow down my computer if I'll fit it?

this is because ur GRUB is gone. search forum for restoring GRUB. And its always better to install linux after windows and not vice-versa because GRUB can redirect to NTLDR but reverse is not possible(atleast not easily).

Boot using Linux CD and at prompt type:

linux rescue

and after following instructions, u'll get sh prompt, now give following commands:

chroot /mnt/sysimage
grub-install /dev/hda

Here /dev/hda refers to ur HDD...

And any reasons for using such a outdated distro?

hi Vishal thanx a lot for your suggestion .

I have run into a small issue. everything works smoothly till i reach the shell prompt.

when i excute the following on the shell prompt:

grub-install/dev/hda

message i get :

file or directory not found

when i execute the following :

grub --install/dev/hda

message i get:

invalid device requested

why such messages !!

So regarding this i have some queries:

1 does every body have their HDD on hda or is it installation specific.
2 if it is installation specific how do i know to which hda my HDD correspond to ?

thanx in advance

check the output of fdisk -l to know the partition name
hda is usually the first PATA disk then hdb
sda is usually the first SATA disk then sdb.

Code:

fdisk -l

The above command will give you the idea of which disk you have installed linux on.

Vishal Gupta · 15-01-2007, 10:40 PM

And also there is a "space" between grub-install and the partition name

JGuru · 16-01-2007, 12:00 PM

Actually, the correct procedure is as follows:

# fdisk -l | grep Linux

This will display two Linux partitions, one is root & the other swap.

You must install GRUB in the root (ie., Linux partition).

For eg.,

# grub-install /dev/hda3

NOTE: In your case it may vary. See the output of the command "fdisk -l"

phreak0ut · 16-01-2007, 05:22 PM

Also, there should be a space between #grub-install and /dev/hda3 I think you are typing wrong. Check it out

srimaya_rath · 19-01-2007, 10:40 AM

Hi,

Yes, now I'm able to see the dual boot. Thank you all...
I was giving wrong command. I was not giving any space after grun-install...
But now I'm getting 3 prompts. 2 for linux and one DOS. Why 2 linux prompts are coming???

One must be failsafe.
Check your /boot/grub/menu.list file.
