UEFI installation and booting
I have Xubuntu 18.04 installed on a Dell Latitude E7440. The machine was refurbished and came with Windows 10, and I wiped the SSD and installed Xubuntu. I have done that many times, in fact, with nary a problem. Sometimes the machine boots (maybe one-third of the time) and the rest of the time I get the "No bootable devices found" with the F1, F2 and F5 options. Currently, the settings are UEFI with secure boot disabled and legacy options enabled. No other combination gets me anywhere close to booting.
I have tried many of the Google-sourced suggestions, including setting up the partition manually, using GPT (which came close to borking the SSD drive), switching from RAID to AHCI (which is the current setting), and trying to turn off Intel fast boot (could never quite figure out how to do that). I have also tried rEFInd, which sometimes allows me to boot into Xubuntu by using the live disk. However, when I installed rEFInd, the bootup list recognized it, but has given a variety of error messages and doesn't boot into Xubuntu.
I am resigned to rebooting until the machine boots or using rEFInd as a live disk, unless someone has a few thoughts about what can be done. Thanks, as always, for your help.
We've come a long say since Xandros and the Asus Eee 900, haven't we?
