I booted the Linux-Mint Fluxbox DVD. There was no "Recovery Mode" but there was a "Compatibility Mode" ! I don't know what it means but I selected that option.

There appeared a black screen and it got hung with the following words:
Starting common unix printing Synchronization ..... [OK]

I waited for 15 minutes no progress happened

I gave up !

Hi,

You don't have any rescue option after booting..?at least let us know other options which it displayed..you do have grub.cfg....can you let us know its contents

The main directories and files used by GRUB 2 include:

/boot/grub/grub.cfg
This is the file most closely resembling GRUB's /boot/grub/menu.lst. This file contains the GRUB 2 menu information but unlike GRUB's menu.lst the grub.cfg file is not meant to be edited.

Each section is clearly delineated with "(### BEGIN)" and references the file in the /etc/grub.d directory from which the information was generated.
grub.cfg is updated by running the update-grub command as root. The update-grub command is a stub for sudo grub-mkconfig -o /boot/grub/grub.cfg. For standardization, the command update-grub will be employed, run as "root" with the sudo.

Nice Info !! So what I am supposed to do now

prayag_pjs · 10-12-2010, 11:24 AM

Get a terminal to type commands,some how choosing all options one by one

prayag_pjs · 10-12-2010, 11:27 AM

Take your Linux Mint 9 LiveCD (main edition), and boot up w/ it.

1) Open a terminal (if you know the partition your original Linux Mint installation was in skip to Step 3)

2) Type
CODE: SELECT ALL
sudo fdisk -l
Hopefully you recognize the partition your Linux Mint installation is on. E.g., /dev/sda1

you have to achieve poit no 1 and source is:

From you grub.cfg its clear that your grub is installed on sdb i.e second harddisk...

You have to install grub now on sda i.e main laptop hardisk ...

And using rescue mode you have to make the entry of external drive Linux partitions so that its listed in first harddisk's grub...

I am Fedora user from last 5 years ... so not able to give exact commands for linux min(ubuntu versions),but I am sure

procedure is same commands are different....

Aquarius_Girl · 10-12-2010, 11:35 AM

Posting this from my external harddisk;

Code:

Eccentric-aquarian anisha # grub
The program 'grub' is currently not installed.  You can install it by typing:
apt-get install grub

What does this mean ?

prayag_pjs · 10-12-2010, 11:42 AM

you booted from external harddisk right?
If so while selection of OS,it showed grub?If so,which hdd grub it was first hdd or second hdd?

about that apt-grub no idea....
