First Install on a New Dell Inspiron 17R

Ok, I have finally retired my old laptop to light duty in my wife’s service, and I have a nice brand new Dell Inspiron 17R.  (Inspiron 7720)  This post was originally intended to document how I initially set it up.  Unfortunately, it wasn’t as straightforward as I wanted.  It took me a bit of experimenting to figure it out, and this post might be a little crazy.


My first task is to prepare the hard drive.  It came with Windows 7 on it, and I still want access to Windows just in case.  So, I need to shrink the partitions to preserve Windows but make room for the Main OS.  I booted into Ubuntu with the try mode of the installation CD.

My first attempt was to use GPartd.  This would have worked fine except I had a new computer with GPT partitioning.

Opening GPartd Partition Editor

Once open, it showed my main drive.

Next step: resize the main OS partition.  I can just right click on the partition and choose Resize:

In all actuality, I found that I could resize the drive from the installer.  That’s the route that ended out working for me.


One of the tools that helped me was GDisk.  You can install it with apt-get …

skp@chestnut:~$ sudo apt-get install gdisk
[sudo] password for skp:

Apparently, I still don’t have it quite right.  gdisk complains that something is wrong.  It’s not worth fixing to me right now because it boots and works for me.  Here’s what it says:

$ sudo gdisk -l /dev/sda
GPT fdisk (gdisk) version 0.8.1

Caution: invalid main GPT header, but valid backup; regenerating main header
from backup!

Caution! After loading partitions, the CRC doesn't check out!
Warning! Main partition table CRC mismatch! Loaded backup partition table
instead of main partition table!

Warning! One or more CRCs don't match. You should repair the disk!

Partition table scan:
 MBR: MBR only
 BSD: not present
 APM: not present
 GPT: damaged

Found valid MBR and corrupt GPT. Which do you want to use? (Using the
GPT MAY permit recovery of GPT data.)
 1 - MBR
 2 - GPT
 3 - Create blank GPT

Your answer: ^C

My SSD does apparently have a valid GPT layout.  Here’s what it says:

skp@chestnut:~$ sudo gdisk -l /dev/sdb
GPT fdisk (gdisk) version 0.8.1

Partition table scan:
  MBR: protective

Found valid GPT with protective MBR; using GPT.

On my first drive, fdisk returns this:

skp@chestnut:~$ sudo fdisk -l /dev/sda

So, I don’t know how helpful this post was, but maybe you pulled a few helpful tips from it.
