View Full Version : Upgraded to Ubuntu 16.04.1 - made a mess of my disk ....

November 26th, 2016, 11:41 PM
I decided to finally upgrade to 16.04.1 from Ubuntu 14.0.
I did a clean install - but the old version is still in its own partition taking up space.
I do have windows 10 on the hard drive and wanted Ubuntu 16.04 installed next to it. 16.04.1 seems to be working fine, but Grub shows the old 14 system still their in its own partition.

Any suggestions? I just want to be sure I have all disk space reclaimed. Normally I would just wipe the disk and install clean, but I need windows in its own ntfs partition.

I always do what you have done, so I know that my backup of /home, data, setttings & list of installed apps is complete & I have fully reconfigured new install while old install is still working.

I keep old install as I always use 25GB which is not large with new drives. But have most data in other data partition(s).

You can erase partition. Depending on where it is on drive it may be easy to combined or just about impossible.
Post this, if you have labeled partitions it will show what they are.
sudo parted -l
And this:
lsblk -o +FSTYPE

Here are the partitions:

Model: ATA Hitachi HTS54502 (scsi)
Disk /dev/sda: 250GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:

Number Start End Size Type File system Flags
1 1049kB 18.3GB 18.3GB primary ntfs diag
2 18.3GB 18.4GB 105MB primary ntfs boot
3 18.4GB 104GB 85.3GB primary ntfs
4 104GB 250GB 146GB extended lba
8 104GB 142GB 38.1GB logical ext4
5 142GB 195GB 52.9GB logical ntfs

Disk /dev/sdb: 2000GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:

sdb 8:16 0 1.8T 0 disk
└─sdb1 8:17 0 1.8T 0 part ntfs

It looks like both sda6 and sda8 contain Ubuntu. I'm not sure which one is the latest version (16), but suspect it is sda8. sda5 looks like windows.

Windows actually boots from sda2 as that has boot flag. Windows only boots from the primary NTFS partition with the boot flag.

You show sda8 mounted, so if you have booted newer install then sda8 is newer install.

What about sda6? what is that? (I see it is also ext4) - the older Ubuntu system (14)?

Thread moved to Installation & Upgrades

Since sda6 was not mounted, it probably is the older install.
you probably can compare UUID, fstab and kernels to know which is which for sure.

But you have the NTFS in between the two ext4 partitions which complicates the issue.
NTFS partition do not like being moved. Repairs always required and sometimes do not work.
Before doing anything be sure you have good backups.

oldfred - Could I just wipe the disk clean - reinstall my windows 10 system (from backup-restore) first and then re-load ubuntu 16 from scratch.
Will this clean up my partitions and free up additional disk space?

Depends on backups.
But I might just delete sda5 thru 8 and reinstall Ubuntu, particularly if you do not have much configuration effort in Ubuntu or have it backed up.
And make sure to back up the NTFS sda5. NTFS does not like to be moved. And any move with lots of data is slow, but you could move it to start of extended partition if you also have it well backed up. And after move run chkdsk on it.

Oldfred - would you suggest backup software to do the job correctly. I do have the windows 10 system backed up already, but need to back up the Ubuntu piece. I also have Kodi installed, but have the data files backed up on the network.

I do not backup Ubuntu itself. With Linux it is too easy to just reinstall.
I do back my data, /home, some files from /etc and list of installed applications.
But having installed several times with every release, but using LTS as main working install have scripted most updates and install is 10 min, update another 10 min or so. Usually fully configured in about an hour.

Some so like full image backups and use clonezilla.

Clonezilla !! of course - thanks!

One final question - what linux syntax would you use to delete/remove sda5 through 8? I'll then do a re-install of Ubuntu 16.04.1.

Thanks again!

I have always used gparted.
Have not used command line since DOS days.
