I'm trying to dualboot Windows 10 and Ubuntu 20.04.
Here's what I did:
Shrunk over a 100GB using the Disk Management utility in Windows.
After booting Ubuntu from a USB, selected "something else" in the installation type.
Formatted the free space to
ext4
mounted on/
. This is a logical partition created at the beginning.
After the installation finished, I did not see the GRUB menu and booted into Windows.
I've already done two restarts and still don't see the option on Ubuntu under the "boot" section in BIOS.
I'm booting using the default UEFI settings.
I haven't created a swap partition because my laptop has 32GB RAM and SSD storage.
Can someone please suggest how I can get around this? (I'm using a Thinkpad T480 if that helps)
Update 1:
Secure boot was already disabled in BIOS (no changes made to this before or after installation)
