Dear Friends,
Let me post some useful tips for linux(redhat).
Tip #1:
Normally we know that the procedure to install linux is to first install windows and then linux. But there can be a thousand reasons for which the situation can arise that u have to format windows and install it afterwards. As a result Linux becomes Inaccessible after installing windows. Now to bring back the dual boot option back Try this :
1. Insert the first cd of linux distribution
2. at boot prompt type linux rescue
3. It will then bring u a shell prompt and there type chroot /mnt/sysimage
4. then check ur disk format by typing fdisk -l ;
5. If it is hda then type grub-install /dev/hda
6. then type reboot to reboot ur computer.
Now the grub boot loader with dual option will appear. As I prefer grub boot loader so I gave the procedure using grub.
Tip #2:
Here is another problem that I he faced durong installation is when he was installing the linux(redhat 9.0) it hanged at some pacages for abt 35 mins and then he just rebooted. But then his computer neither boot to wiindows nor linux and showed a text like GRUB and hang there. In a problem like this try
1. insert win 2000 cd (bootable)
2. select repair option which is 'R'
3. Then choose 'C" for command prompt.
4. at the dos prompt type:
a:\>fixmbr ; it will then ask for some confirmation and just say 'yes'
a:\>fixboot ; it will then ask for some confirmation and just say 'yes'
At last reboot ur computer and then u willl get ur winodws back again.
Tip #3:
As we know there are 6 run levels in linux from F1 to F6. To get more run levels in shell mode
1. open /etc/inittab using vi editor ( as u can use any editor of ur like).
2. there u can see something like this
#Run gettys in standard runlevels
add one more line there like
7: 2345:respawn:/sbin/mingetty tty7
now u get another run level in F7.
Friends pardon my english as I am not that good but hope u understand.[/list]
