Booting iso images with GRUB 2

Booting iso images with GRUB 2 With thousdands of linux distributions around , booting iso images with out burning it to a cd or dvd  saves a lot of money and effort.   Let us try to boot system rescue cd. I have  ubuntu  lucid lynx installed on my laptop. Let us see how to boot   system rescue cd  from the iso image.   Get the latest system  rescue cd from here. I keep all my iso images under /boot/iso folder . You can choose a different folder. (but note the exact path) Add  the following lines to   /etc/grub.d/40_custom file   menuentry " SystemRescue CD ISO " { loopback loop (hd0,1)/boot/iso/systemrescuecd-x86-1.5.8.iso linux (loop)/isolinux/rescue64 setkmap=us isoloop=/systemrescuecd-x86-1.5.8.iso initrd (loop)/isolinux/initram.igz }  You may have to tweak ( hd0,1 ) depending on  the location of your  iso image.   The line         loopback loop (hd0,1)/boot/iso/systemrescue...

Blogger Play and Bloglines Wall of Images

Blogger Play and Bloglines Wall of Images Blogger Play is a self-running slideshow of photographs recently uploaded on Blogspot blogs. Other than the image, you also get to read a short excerpt of the accompanying blog post and the profile of the blogger. Excellent implementation.

Wishlist - They should offer categories in Bl...

Booting Disk Images in Linux

Booting Disk Images in Linux A Picture can be Worth a Thousand Words Sometimes there is no substitute for booting a computer to gather data.  But the forensic consequences of  directly booting the system under investigation are prohibitive.  And, while it can be possible to restore a computer image to another hard drive and install that drive in the computer hard drive for booting, this can be costly, very time consuming, and you only get one shot before youve changed the data from original (and repeated boots may be desirable depending on the investigation). In response to this, tools like LiveView were created.  The concept was to boot the forensic image, rather than restore it, and capture all system changes in a disk cache.  The operating system could be booted quickly and repeatedly from an original state.  However, I never found LiveView to be very effective, and it the past few years I have avoided Windows-based tools whenever possible .
