How to apply changes made by fdisk

  • 772

I have a SSD, allocated 100G for Ubuntu and 150 G for Windows 10, then I decided to increase the volume of Ubuntu. In Windows, using EaseUS, I freed 50G, then in Ubuntu I ran fdisk. It showed up 50G as a free disk. Then I hit Resize and it offered 150G as I guess calculated based on my free disk. I said yes and then selected Write and then rebooted the system.

fdisk -l /dev/sda shows:

Disk /dev/sda: 238.49 GiB, 256060514304 bytes, 500118192 sectors
Disk model: ADATA SX900     
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: 0x6ef3495a

Device     Boot     Start       End   Sectors   Size Id Type
/dev/sda1  *         2048    718847    716800   350M  7 HPFS/NTFS/exFAT
/dev/sda2          718848 295313090 294594243 140.5G  7 HPFS/NTFS/exFAT
/dev/sda3       295313408 296364031   1050624   513M  b W95 FAT32
/dev/sda4       296366078 500117503 203751426  97.2G  f W95 Ext'd (LBA)
/dev/sda5       296366080 500117503 203751424  97.2G 83 Linux

So far, so good. However I'm not sure if the changes has applied because when I tried to check free disk using System Monitor it shows 100G and 97% used:

So, did I increase the volume? How do I apply changes made by fdisk?

    As far as I can see you haven't changed the size. You seem to have 3 "main" partions:

    • sda 1+2 windows partition
    • sda 3+4 Fat32 partition
    • sda 5 Linux partition

    sda 5 is shown with 97.2 GB. The sum of all is around 350 gb. So where should that additional space come from?

    I would advise to use gparted for resizing partions. I've used it even on devices that had a windows partition. It always worked.
