How to restore grub in linux?

I had a problem on my computer before. I accidentally damage MBR (Master Boot Record) on my PC and wasn't able to use my system for several days.

After a thorough research on the internet I was able to restore grub and boot back to my linux system.

Here are the steps I did:

1. Download a Live CD on you linux distro.
2. Burn it on a CD/DVD/USB.
3. Use it as first boot on you computer.
4. When you are on it, you can gain complete access to your lost Linux OS.
5. Mount you linux system into /mnt/my-linux-os
- su
- mkdir /mnt/my-linux-os
- mount /dev/sda{any number if you have partitioned your disk} /mnt/my-linux-os
6. Type 'grub-install /dev/sda' (to install Grub to the MBR of the 1st HD)
7. Restart and you should get the boot menu.

Or, you can also try this one:

1. Boot your Live CD.
2. Use terminal, login as root: su
3. type the command 'grub' and press enter
4. type root (hd0,0)
- or if your not sure the right one, you can type 'find /boot/grub/stage1'. This will output something like '....(hd0,5)'. use that one in this step.
5. type setup (hd0)
- just remove the comma and the next number.
6. type quit
3. Reboot.

How to make movie of jpeg images?

It's just very easy to make video/movie on Linux operating system (in my case Fedora).

You can try using 'convert' command in the terminal.

convert *.jpg movie.mpg

Or, you can also try: (just replace the variable with '$' with true values)

mencoder mf://$PIC_DIR/\*.jpg -mf w=$WIDTH:h=$HEIGHT:fps=$FPS:type=jpg -ovc lavc -lavcopts vcodec=mpeg4 -oac copy -o $DEST_VIDEO

Hope that helps!

Windows 7 Ultimate

Wazzup everyone, been busy for awhile, Christmas, New Year, outing, beach, work, and some more. Well, it's been really busy but fun, really really fun.

Now, I'll share with you my experience on this latest Operating System (OS), by Microsoft Corporation, Windows 7 (Ultimate). This one is even better than XP and Vista indeed. Well of course you wouldn't expect a newer version to be less better that the older one right?

Windows 7 is the latest public release version of Microsoft Windows, a series of operating systems produced by Microsoft for use on personal computers, including home and business desktops, laptops, netbooks, tablet PCs, and media center PCs.
