Dual Boot Windows 8 and Ubuntu 12.04 LTS in Dell Laptop

So I was given a new laptop by Torsten yesterday because I used to use Mac that was really not a good platform of doing real *work* of a computer scientist.  And my old Ubuntu platform laptop was becoming really slow for my purposes.  As the new Dell laptop came with Windows 8, I had to install Ubuntu along with it to make my work going.  I was really having trouble installing it because recently they have updates the BIOS firmware of laptops which they call UEFI. They keep the previous setting of BIOS in a mode called Legacy.  First, as the UEFI mode was not allowing to make a choice for the boot order selection, I went to Legacy mode and installed Ubuntu under it.

But turned out that if Windows 8 is installed under UEFI mode and Ubuntu is under the Legacy mode, your laptop will not allow the enlisting of the two OS-es to make a choice.  You have to install the two OS-es under the same mode.  Thus I found out the most legit way to do it:

After installing Ubuntu,you have to update the grub to detect the installed Windows 8 as well.

For that run the commands described here from Ubuntu.

Probably you will end up having a lot more options that usual, you can delete the extra options by editing

Since one is not bound by fixed working hours, they can schedule their work at the time when they feel most productive and convenient to them.

People mostly find that in this situation, their productivity is higher and stress levels lower. Those who like isolation and a tranquil work environment also tend to prefer this way of working. Today, with the kind of communication networks available, millions of people worldwide are considering this option.

    Women & Men who want to be independent but cannot afford to leave their responsibilities at home aside will benefit a lot from this concept of work. It makes it easier to maintain a healthy balance between home and work. The family doesn't get neglected and you can get your work done too. You can thus effectively juggle home responsibilities with your career. Working from home is definitely a viable option but it also needs a lot of hard work and discipline.
