I made a dual boot on my laptop.

  1. I backed up all my files on an external HDD, destroyed the internal hard drive's partition table by creating a new one from an Ubuntu live USB,

  2. Partitionned as following:

Windows (10) partition (150 GB) formatted as NTFS Ubuntu (18.04.1) partition (150 GB as well) formatted as Ext4 DATA partition (1.5 TB) formatted as NTFS for now, looking for a better choice

  1. Installed Windows 10 - I had to delete the Windows partition in the Windows installer, then it created all it needed by selecting the empty space.

  2. Installed Ubuntu - Only customized the root mount point and GRUB location (on the Ext4 partition)

Now I'm looking to mount my data partition in both Windows and Ubuntu automatically at startup. I, of course, have disabled fast boot in Windows. I have no idea how to achieve this in Ubuntu (I already know how to assign a folder to a specific location on the hard drive in Windows).

Ideally I'd use ExFAT but I'm not sure Linux can read/write on it.

EDIT: Here's the output of sudo parted -l:

Model: ATA ST2000LX001-1RG1 (scsi) Disk /dev/sda : 2000GB Sector Size (logical/physical): 512B/4096B Partition table : gpt Disk Flags:

Thanks in advance.

  • Sorry I forgot basic politeness and didn't greet you guys and this is my first post and I can't see an "edit" feature.

    (1) Below the question there are "share", "edit", "flag"... (2) no need for greetings, a Q&A site works best without them ;) (3) NTFS is fine for a shared data partition and in Ubuntu there are several methods to mount it automatically on boot. There's no point in using exFAT.

  • Hi and welcome to the site! First of all, don't worry, in fact we prefer to avoid greetings (and often edit them out) here since we like to keep things simple and avoid "chit chat". That said, the edit button is just under your question's tags, next to "share".

    Now, please edit your question and show us the output of running sudo parted -l which will list your disks and tell us which one of those you want to have available. Also, please explain what you mean by "better option" than NTFS. What's wrong with NTFS? You don't want exFAT for a non-flash drive.

  • @karel the answers there don't address how to automatically mount the drive on boot.

You can indeed use exFAT on Linux after installing the exfat-fuse exfat-utils packages from aptitude on Ubuntu. I would recommend you stick to NTFS though. exFAT was designed for smaller drives.

  • You may add ups and down for NTFS. I also like to use NTFS for a shared partition but it's not able to keep permissions.

  • I thought exFAT was "more dual boot friendly", hence why I was hesitating.
