REMOVE OLD KERNELS

I tend to be on #ubuntu to help others. Today, an interesting question
popped up, how do I clean the old linux images and headers?

Each linux image / header has its own dir in /usr/src/

Let's start, uname -a ... do NOT remove this image

Let's do a sudo apt-get update ... make sure it is clean

If, for some reason, you get errors, try sudo apt-get -f install (fix broken)

Let's get a list of all the images, dpkg -l | grep linux-image

Another UEFI Adventure

I recently bought a new used Lenovo V570 laptop and wanted to dual boot it with windows 7 and Ubuntu 14.05. I found the drive had been erased with the exception of a recovery partition, but I was unable to access it.

Step 1:
I tried using the original format which was msdos and installed a fresh Windows 7. Unfortunately that failed. The Windows disk required GPT.

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

During install fests we sometimes need to install grub on a disk that is currently not mounted on root. For example, if a system can't be booted from its hard drive, but can be booted from a live usb, we want to boot from the live usb and "repair" the hard drive by installing grub on the hard drive. Once the hard drive is "repaired," the system can be booted again from the hard drive.
