    Missing 100GB after installation failed.

    I tried to install Ubuntu multiple times yesterday with no avail. I have a brand-new 1.5TB HDD and had 870GB left on it.
    During the first step of installation (resizing partition using 100GB) I got this error:

    Ubiquity:5851): Gtk-CRITICAL **: gtk_widget_draw: assertion '!widget->priv->alloc_needed' failed

    I then turned my PC off and booted back into windows to see there was 100GB missing. I looked at my partitions within windows AND Ubuntu 'try' mode. There's no partitions and Ubuntu didn't install... I really would like to get my 100GB back, can anyone help?

    Is there a 100GB unallocated space? If the partitions were never created, that would leave the space as unallocated. Windows might have issues seeing it since it was done by linux tools, but Gparted or cfdisk or parted in ubuntu live mode should see it fine.

    Also, don't resize your windows partition with the ubuntu installer. Use the windows Disk Management tool. Winodws doesn't like other tools touching its system partition. Once you have the unallocated space created by the windows shrink, you can install ubuntu using the automated or the manual method, as you wish.

    I used Gparted and there's only like 10MB unallocated.

    Can you post a screenshot of Gparted?

    What makes you think you have 100GB missing?

    All of your space is accounted for by the 2 NTFS partitions

    Maybe because before attempting installation I had 880GB and after it failed, I only had 750.

    Re: Missing 100GB after installation failed.

    I have no idea what you are talking about, is it the free space you see inside the C: partition in windows?

    Your disk is 1.36TiB which is approx correct for a disk of 1.5TB and as mentioned above, all space is accounted for.

    Now, how much unsued space you see inside C:, that is a different subject and is up to windows. That red warning symbol on sda2 usually means you need to run chkdsk in windows. So, boot windows and run chkdsk on C:.

    The failed install may of made a filesystem overhead for the etx4 partitions which isn't counted as a partition but instead part of the filesystem table.

    That has nothing to do with it.

    The 5% reserved space issue is for ext4 filesystems, which the OP doesn't have.
