/dev/sda1 1 5 40131 de Dell Utility
This partition looks good and doesn't need to be resized.
This looks like your Win's 7 Recovery-
These are your Win's 7 Partions and all is good.
/dev/sda2 * 6 2451 19644416 7 HPFS/NTFS
/dev/sda3 2451 26597 193953017 7 HPFS/NTFS
However this extended partition....I am not sure if it's one you created or the manufacturer's of your computer created. I need to find that out-
And your Linux Distro is on sda5 and sda6 is the swap partition that you created-
/dev/sda5 26597 38407 94863360 83 Linux
/dev/sda6 38407 38914 4067328 82 Linux swap / Solaris
Looks like you need to do one of 2 things-
You can use a program/application called 'G-Parted' to re-size your Linux distro.(should of came with your disto)
If not it can be installed-
(Or) you can re-install Backtrack and make the partition for your journaling file system (/)ext3 only 20 GB
And allocate 1 or 2 GB's for your swap
70 GB is a tad overkill for your Backtrack-
Is this a Dell laptop?
If so do you know the model so I can look it up?
Be back to help you in a little while I need to find out how big in MB or GB Backtrack is and confirmation of the
Extended partition I'll either have to find the answer to that on your computer manufacture's website in the list of specifications.
