Gautam Buddha's Sayings

Hi Friends,

There are lot to experience in and for this life. Buddha's thoughts take to us to internal journey. We need to know ourselves before heading towards any other person, thing, etc.

---He Said :-

* "Chaos is inherent in all compounded things, Strive on with diligence."

* "You will not be punished for your anger, you will be punished by your anger".

It is very difficult to be yourself

If we love someone, we become like him.
If we hate someone, We become like him,
If we have a strong enemy, Sometimes We think, act and react like him,
All these leads us to be like others,
But very few people success in knowing themselves, As we study less about ourselves.
So we need to give time to study ourselves first.

grub grub grub grub grub repeated message LINUX

 Dear Friends,

My linux system was giving multiple or infinite message of GRUB:-

GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB GRUB

Now to solve this, google our Best friend helped me  in resolving this problem.

Step 1 :- Created a bootable USB.
Step 2 :- Booted the system with setting the USB bootable option in BIOS.
Step 3 :- when booted, 3 options appeared as usual to install the OS, booting to rescue mode.
press F5 key to rescue mode and bring to prompt.

now write

linux resuce

it will bring the system to rescue mode with selection of Language and an option to skip the network connectivity. We also have to skip the mounting of File system part.

It will bring the system to # prompt.

From this # prompt i.e. linux rescue mode. We can reduce the root volume if needed. SO bringing the topic back to grub issue. 

Now write command grub at linux rescue # prompt. it will bring the system to grub> prompt. like below :-

#
#grub
#




grub> find /grub/stage1
(hd0,0)
grub> root (hd0,X)
grub> setup (hd0)

after this my system was booting. and the message which was coming, gone.

but it showed corrupted lines in kernel and disk selction so edited the same and then rebooted. 

we need to use tab and write the correct kernel path, boot the system with the correct path of the kernel. System successfully rebooted. For making this change permanent. we need to edit the file /etc/grub.conf. like bwlow is the system gub.conf which worked well.


[root@localhost grub]#
[root@localhost grub]# cat /etc/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.
#          root (hd1,4)
#          kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
#          initrd /initrd-version.img
#boot=/dev/sdb
default=0
timeout=5
splashimage=(hd0,4)/grub/splash.xpm.gz
hiddenmenu
title Red Hat Enterprise Linux Server (2.6.18-308.el5)
        root (hd0,4)
        kernel /vmlinuz-2.6.18-308.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet crashkernel=128M@16M
        initrd /initrd-2.6.18-308.el5.img
title Other
        rootnoverify (hd0,0)
        chainloader +1
You have new mail in /var/spool/mail/root
[root@localhost grub]#


My system's Other OS is Windows which was also facing problem While booting up. Now it is also fine.

Now my system is giving me an option of booting the system with DUAL BOOT option.

A little tribute to Nirbhaya

Hi Friends,

This is a small tribute to the bravest girl ever, Nirbhaya. She is still living in us with all power she had.

----

Main ek Ladki hu,
Main Nirbhaya hu,


Majboot kar Iraade Main jeena seekhu,
Zameen par sakht kar kadam uthuun,
Roshni Meri Surya ko Jala de,
Main wo hu Jo Darr Ko b dara de,
Darr ka har pal Jhuk Jaye Mere Saamne....
Main wo Shakti hu har Kamzor ko jeena sikha de....

Main ek Ladki hu,
Main Nirbhaya hu....

Pooja mujhe mere bachpan mein,
Mana mujh ko tab durga ka roop,
Ab ye Durga Jaag chuki hai mujhme,
Ab atyachaar na sahegi,
Ab bechari na rahegi,
Ban kar chandi ka swaroop..

Main Ek Shkati hu,
Main Durga Hu,
Main Nirbhaya hu,



----

The Bravest Girl Nirbhaya..
