I recently bought an HP Pavilion Laptop 15t-cs300 and wanted to install Ubuntu 18.04.3 LTS on it. (dual boot with windows 10)
I used a USB installation drive with rufus. I booted it up and installed Ubuntu, however, I cannot access grub.
I installed grub to the windows boot manager partition and when I use efibootmgr I see ubuntu as one of the options.
However, when I reboot the computer to try to access the boot loader, it magically disappears and leaves me only with the windows boot loader. I was wondering if this is a UEFI/BIOS issue. Also, I'm wondering if anyone has any experience installing Ubuntu on this specific or related computer.
