It fails with the following error quickly flashing: error: file `/boot/` not found Then followed by: error: cannot allocate kernel buffer. error: you need to load the kernel first. press any key to continue... This occurs when doing an update from 19.04 to 19.10 and also when just booting off a usb drive with 19.10. When booting off the usb drive. The first error flashes quickly before displaying the usb installer options. Selecting any install / boot option results in the second error about kernel buffer. I have tried all combinations of bios settings I can think of, such as toggling secure boot and other options. The only thing that made a difference is booting via USB with LEGACY EXTERNAL DEVICE BOOT. This allows the installer to complete, but I cannot then boot off the hard drive. I have tried the same USB drive with 19.10 on a Dell XPS 7590 with BIOS 1.2.3 and the USB stick boots fine. I have also tried many different USB drives on my 9570. I have tried a few daily builds of 20.04 with the same result. I tested with 20.04 beta as well. Note: 19.04 and earlier continues to work no problem.
