Simple linux tweaks!!

Changing the Boot sequence!!

Here is a noobish but useful tip for people having more than 1 OS. When we install linux after windows, the default OS becomes linux. To change this sequence follow the steps given below.

• Go to root->boot->grub->menu.lst
• sudo chmod a+w menu.lst
• change default 0,to the line no of the preferred OS.

Creating .deb file

After .\config

Instead of make install do check-install or sudo apt-get install checkinstall

.deb is created in source dir.

GRUB 17 error

I have had this error 17 many times from having bad power downs and crashes for other reasons. In most of my cases the problem is usually from a bad magic number in the root partition. This can be easily fixed by doing this:

a. boot from any live CD (ubuntu install disk works for me)

b. open accessories->Terminal

c. in terminal type "sudo e2fsck -b 32768 /dev/hdaX

replace the hdaX in line above with the disk that you have your root mounted from

for example sudo e2fsck -b 32768 /dev/hda2

in my case I have windows installed in /dev/hda1 and my root partition for ubuntu in at /dev/hda2 also if -b 32768 fails you can try other numbers including -b 8193 or -b 98304 or -b 163840.
