notes on installing grub on a disk that is not mounted as root

AZ Loco - Sat, 2014, May17 - 22:39
  • boot the system with a live usb
  • make sure that the system hard drive is mounted. Find out what its block device name is and on what folder it is mounted. For this you might want to use the "df" command.
  • make yourself the super user by issuing the command "sudo su -"
  • use the mount command to mount the /dev and /proc mounts to "mountpoint"/dev and "mountpoint"/proc
  • chroot into "mountpoint"
  • run the following command "grub-install "blockdevname"

Let's assume that your system is booted via live usb, and the partition on which you have your operating system is /dev/sda3, and that partition is mounted as /mnt/hdsystem, "blockdevname" is /dev/sda (note that it is /dev/sda, it is NOT!!! /dev/sda3!!!), and "mountpoint" is /mnt/hdsystem.

Siege Your Servers!

LinuxJournal - Mon, 2014, May12 - 14:59

Setting up Web servers is fairly simple. In fact, it's so simple that once the server is set up, we often don't think about it anymore. It wasn't until I had a very large Web site rollout fail miserably that I started to research a method for load-testing servers before releasing a Web site to production. more>>

Android Candy: Waze

LinuxJournal - Thu, 2014, May08 - 14:08

I have a love/hate relationship with Waze. The idea of peer collaboration regarding traffic, combined with the technology to accomplish it on an enormous scale is truly amazing. Yet, every time I've used Waze myself, it's been an exercise in frustration. It has insisted I turn left off a bridge, and then it refused to reroute me when I didn't. more>>

SciPY for Scientists

LinuxJournal - Wed, 2014, May07 - 10:19

In my last article, I looked at NumPY and some of its uses in numerical simulations. Although NumPY does provide some really robust building blocks, it is a bit lacking in more sophisticated tools. SciPY is one of the many Python modules that build on NumPY's. more>>
