Installed Ubuntu twice - can't delet the old one.

Let's assume you are going to use your Ubuntu Live CD. Boot it up, then go into System>Administration>Partition Editor. GParted will boot up and show you the partitions on your hard drive(s) (you can switch between drives using a button on the top right). You will see your 2.5 GB partition, your 18 GB partition, and your linux-swap partition, and also a table listing them with some further info to help identify which is which.

-Get rid of your 2.5 GB partition - right click on it and select 'delete'.
-Then expand your 18 GB partition to use the extra space - right click and select Resize/Move, then increase the size to max. available.
-Then click the big 'apply' button.

Simple, right? No need to fork out $35 (unless of course you want to). Gparted is on pretty much every live linux CD out there.



First of all I’m a complete newbie to Linux and my problem is similar to this thread (post moved to new thread and link to older thread added by moderator). I downloaded Ubuntu 14.02 32bit and upgraded to Ubuntu 16.04 32bit. Its working fine now but my disk is almost full because I downloaded it twice (or maybe three times) by mistake. Ive tried to fix it myself but had no luck. here's what i did:

I got the following partition info from Tereminal using: sudo fdisk -l:

Disk /dev/sda: 111.8 GiB, 120034123776 bytes, 234441648 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x006c006c

Device Boot Start End Sectors Size Id Type
/dev/sda1 * 63 136884168 136884106 65.3G 7 HPFS/NTFS/exFAT
/dev/sda2 136884222 214972415 78088194 37.2G 5 Extended
/dev/sda4 215896064 234434559 18538496 8.9G 7 HPFS/NTFS/exFAT
/dev/sda5 152602624 210917375 58314752 27.8G 83 Linux
/dev/sda6 210921472 214972415 4050944 2G 82 Linux swap / Solaris
/dev/sda7 136884224 152602623 15718400 7.5G 83 Linux

Partition table entries are not in disk order.

And since there are three Linux entries I presume the /dev/sda5….27.8G partition is the one I did by mistake.

I’m trying to delete it using GParted Partition Editor but having no luck.

When I click my RHM on /dev/sda5...27.8G 83 Linux and select Delete I get the following error:

Unable to delete /dev/sda5!

Please unmount any logical partitions having a number higher than 5

Now, /dev/sda6 doesn’t have an option to unmount so I did it on /dev/sda7 and got the following error:

Could not unmount /dev/sda7

# umount -v "/"
umount: /: target is busy
(In some cases useful info about processes that
use the device is found by lsof(8) or fuser(1).)

I’ve done this a number of times but get the same errors every time.

Can anyone please help?
