Im new to Linux and know almost nothing about bootloaders and BIOS. Im trying to install Ubuntu 19.04 on my win10 machine, but after 7 hours have been unable to install, as Ubuntu will not recognize that win10 exists on the filesystem and will only allow the Erase option.

I have gone into the BIOS and played with every combination of settings that have been mentioned on several guides/questions relating to this problem

What im Trying to install: Ubuntu 19.04 from a USB drive (called Ubuntu amdx64)

What im trying to install on: Windows 10 version 1903 Build 18362.388

I formatted the drive with Rufus using both of the following settings Rufus settings 1 Rufus settings 2

Things that have been done since I started: Disabled Fast Boot Disabled Fast Startup in Win10 Made sure C: drive was error free and ran chkdsk

I have performed any combination of:

Enable/Disabled CSM Enable/Disabled Secure Boot, as well as loading/unloading dbs Enable/Disable Windows UEFI booting (Switching between Windows UEFI and "Other OS") Changed bios load order

Here are my system specs My machine info

As noted i have looked through several guides but still i cant make them coexist at all.

Thank you for any and all responses

EDITS: changed out machine info screenshot as it did not load properly

  • The window which says erase everything, does it contain an option saying `Something else' ? Nov 20, 2019 at 4:53

If you already have Ubuntu 19.04 on USB you should be able to boot it using the Try Ubuntu without installing option.

Once Ubuntu is loaded, go to Show Applications --> Disks. Resize your Windows partition to create an unallocated partition of (ideally) at least 25 GB.

Format the unallocated space to Ext4 Filesystem.

Install Ubuntu with either Install Ubuntu icon on Desktop (highly recommended) or reboot and follow the normal process.

Make sure you use the custom install option and select the Ext4 partition that you just formatted.

Wait for the installation to complete and you are done!

  • There's nothing to disagree with here except that the recommended size is of the Ubuntu partition is at least 25GB.

You can install GParted using sudo apt install gparted, then launch it using sudo gparted.

Make sure that your disk is selected, then resize the windows partition to the size that you want. Then move to the unallocated space and press format to ext4 filesystem.

After that, return to the ubuntu installer and do the necessary steps. When you reach the install menu, press custom install and select the partition that you just formatted to ext4. Then wait for the installation process to complete.
