My Blog After 12 Years

2022-01-13T03:29:00.001+02:00

After 12 years from my latest post, and after 10 years from my graduation, I decided to resume my favorite habit of writing.

I will write my thoughts about my career, about the challenges I encounter every day. I will write here about the technical ones. I am thinking of writing my personal thoughts but in another blog.

My Experience with Xubuntu

2011-10-27T23:04:00.000+02:00

Hi,
It's too long since last time I posted. Actually I don't know why, may be because there were no an interesting technical topic to speak about,
today I'd like to speak about my light experience with Xubuntu. I have heard about Xubuntu while I were searching for another good distributions, I have figured out that XFCE desktop environment (which is the actual difference between Xubuntu and Ubuntu) has better performance than Gnome, but on the other hand it has less gui effects than Gnome. I advise you to try XFCE desktop Environment.
Simply open Ubuntu software center, type in the search textbox Xubuntu desktop system.
after you install it just reboot or logout, and when you are asked to login select the session as Xubuntu session.
Good luck with Xubuntu.

how to add windows to grub menu

2010-09-02T19:17:00.000+02:00

Hi Dear reader,

Since I'm new to Ubuntu, After I had installed it (clean install), I couldn't access Windows Vista. My Machine automatically selected Ubuntu,I guessed that my windows was dropped but I was wrong. the matter that the grub didn't detect windows installation I think this was because previously I installed Ubuntu inside windows via wubildr.

In order to solve this problem we should follow those instructions:
Firstly, we should know the windows partition via this command in the terminal:

sudo fdisk -l /dev/sda

then notice the windows partition and memorize your windows partition according to me is dev/sda2 off course it may differs.

then, we have to create a new file with name 11_Windows
via this command

sudo nano /etc/grub.d/11_Windows

this created a new file and we have to add the following lines:



#! /bin/sh -e

echo “Adding Windows” >&2

cat << EOF menuentry “Windows 7″ { set root=(hd0,1) chainloader +1 } EOF

then save the file..

Note: Bare in mind that in earlier version of GRUB, if your Windows was installed on first partition then you need to give root=(hd0,0). Thats how GRUB used to number partitions. Starting from GRUB 2, you need to giveroot=(hd0,1), if your Windows is installed on first partition. So under GRUB 2 it looks like this:

First partition (/dev/sda1): root=(hd0,1)
also you may change "Windows 7" to "Windows XP" or "Windows Vista" according to your windows instillation.

then type:
this command

sudo chmod a+x /etc/grub.d/11_Windows

then this command:

sudo update-grub

you should see someting like those:

# sudo update-grub
Generating grub.cfg …
Found linux image: /boot/vmlinuz-2.6.30-9-generic
Found initrd image: /boot/initrd.img-2.6.30-9-generic
Found linux image: /boot/vmlinuz-2.6.30-8-generic
Found initrd image: /boot/initrd.img-2.6.30-8-generic
Adding Windows
Found memtest86+ image: /boot/memtest86+.bin
done

Now Congratulations you've add windows to your grub menu so, Reboot and enjoy dual boot
