There are parts of the company which are very Linux friendly (as can be seen by some of the projects on their GitHub page [0], like the thunderbolt for Linux driver and BIOS flash for Linux utility they maintain). This applies mostly to servers and enterprise products, but there are actuall workstations, laptops, etc. that have good support for non-Microsoft operating systems. They even sell a laptop with Ubuntu pre-installed (the XPS 13" Developer Edition). But then, when it comes to consumer-targeted products, the customer there wants to dictate what can and cannot be done (bearing in mind that the customer is actually Microsoft, not the purchaser of the computer itself). That's why most of those systems (i.e., non-servers) end up with locked down EFI configurations and hardware which is not well supported or flat out won't work with Linux. That's just how it goes.

I haven't had experience with this specific Inspiron model, but I'd be surprised if it were any different. https://www.dell.com/support/manuals/us/en/04/inspiron-3668-desktop/inspiron%203668_sm/system-setup-options?guid=guid-2d1e8a4f-e5a2-49eb-823d-707f15a41edc&lang=en-us appears to be the appropriate manual for working with the UEFI on this model. It lists the same "Enable Secure Boot" and "Enable Legacy Option ROMs" settings I was expecting to see, and IIRC the final setting (which may be optional) is under what "Boot List Option", mentioned near the top of the document. So it's likely that this is in fact supported. That said, I've also had problems with formatting, partitioning, and installing to a hard drive (on one of these systems) for UEFI boot from a "legacy"-booted external device - so there may be reason to go for a UEFI-style bootable external device anyway. (IIRC, the reason why "legacy" boot to internal devices is now prohibited is not a Dell decision, or a Microsoft one, but a consequence of an Intel decision which they've implemented in their motherboard chipsets; Intel has apparently decided to drop all support for non-UEFI boot to internal permanent hard drives, presumably for security reasons of some kind, and since that's hardware Dell can't override it in the firmware. So this won't be just on Dell computers, at least not going forward, although IIRC AMD has not yet taken a similar step.) -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.

I think, BIOS of your PC supports native EFI mode only, on top of restricting ability to manually select bootable media. (I've never seen a PC with restrictions like this, yet.) Is there an option to at least disable Secure Boot, or is it forced too? I'd try to switch hard disk with pre-installed OS to a blank one (temporarily disconnect all hard disks for a test, if you don't have a blank one) and make sure you've prepared UEFI-compatible bootable USB media. If bootable USB media was made correctly, and there is no other bootable disk found, it should start EFI bootloader from USB. And if not, it is possible that Secure Boot prevents it from loading by checking signature of bootloader against pre-installed in BIOS certificates issued by Microsoft. Usually there is an options in BIOS to disable Secure Boot or install alternative certificates. I've seen successful attempts to trick UEFI to load "grubx64.efi" EFI bootloader by placing and renaming it to "/EFI/Microsoft/Boot/bootmgfw.efi" I think it is also possible to edit BCD boot loader settings to add one more bootloader entry to the list and chainload "grubx64.efi". Just like grub chainloads other bootloaders, but the other way around. I've not tried this, but it looks doable. -- With kindest regards, Alexander. ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ Debian - The universal operating system ⢿⡄⠘⠷⠚⠋⠀ https://www.debian.org ⠈⠳⣄

Since last upgrade of the companies notebook it can no longer boot from NFS (TFTP boot) or USB stick. The reason is UEFI+Secure boot. Unfortunately they protected the bios with password, I do not have. Might be you look into UEFI and secure boot unless it is defaulted and you can not remove, which I doubt.
Re: Dell BIOS
Mirko Parthey composed on 2017-01-17 00:36 (UTC+0100): The BIOS clock could still have the correct time despite a dead battery because the Linux system gets the time from an NTP server and writes it to the BIOS clock on shutdown. The clock then runs on ATX standby power and will only lose its memory when the power cable is removed. The same applies to the BIOS settings. That's the logical expectation, but not the way it always works. Just hours ago on a Dell SFF Optiplex 745 I found a dead battery. After installing a new one I decided to remove it after first setting the BIOS clock and rebooting. Without having removed the power cable, only removing the battery and no other changes, on first subsequent boot it reported BIOS settings reset, and sure enough, clock was reset to its build date just short of 10 years ago. -- "The wise are known for their understanding, and pleasant words are persuasive."

There may be a function key that brings up a BIOS boot menu. For Dell machines, it should be F12. Other candidates are F8 and F11. Choosing an entry in the menu takes effect exactly once, then the previous boot order is restored. This feature might be useful to you if the entries are the same each time and appear in the same order. > I don't think the CMOS batteries are dead because the > clock still seems to keep time Changing the battery is certainly worth trying.

I've seen thousands (literally: some television cameras I have repaired contained over 100 dodgy capacitors) of surface-mount aluminium electrolytics leaking. The electrolyte used in these [Japanese] capacitors was obviously very conductive, but it also dissolved copper. There was literally no limit to the types of fault caused by some tracks disappearing and some being bridged together. The mention of 'amine' rings a bell, when hot this electrolyte smelled of fish, so the quick way to distinguish between harmless flux left on a PCB after manufacture, and the brownish electrolyte, was to touch a soldering iron to it.

These dells could possibly be in that group as one has a BIOS date of August 1, 2001 and another is July 12, 2000. Both are Dell desktops so they could possibly be in that group.

Re: Dell BIOS
Martin McCormick composed on 2017-01-16 11:52 (UTC-0600): I don't know how common this is but the BIOS' of two Dell Optiplexes plus the BIOS of another Dell Dimension don't stay set the way one would like them to. As a computer user who happens to What models are they? If of approximately 2002 to 2007 vintage, they could be victims of the bad capacitor plague: http://en.wikipedia.org/wiki/Capacitor_plague I've resurrected several, but also failed on several, by replacing bad caps. be blind, the setup process is a royal pain in the backside because since there is no OS booted, the only output device is the VGA output. I have to hook it up to a monitor and have someone like my kind and patient wife or, before I retired, a coworker change the boot sequence order from floppy-C:-CDROM to CDROM-floppy-C: or CDROM-C:-floppy which prevents the hard drive from grabbing the boot sequence each time. I sympathize. I have a bunch of different models Optiplexes. I've had three different ones waste an obscene amount of my time lately. Each of these is installed in locations that make opening them up for maintenance a significant inconvenience. The first, a 780 with a Dell PCIe DVI port card and connected via DisplayPort, when shut down from Linux puts my new Dell 21:9 display to sleep in a fashion from which it cannot be awakened until after I remove and replace the 780's power cable. Even after a BIOS update it took quite some time to determine that the only way to acquire normal behavior was to remove the DVI port card. The second, a 745, even with latest BIOS, has taken to reporting low battery voltage, after the previous battery voltage was reduced to nil. I replaced it with a brand new battery with measured voltage up to specification, but it still pauses at every power up to report low voltage even though clock is correct. The third, a 270, has decided to randomly report failed RAM. Each time it has done so I've opened it, wiggled or removed and replaced the sticks, and then it would work normally. As I write this I'm running Memtest86+ on it after having replaced both sticks with matched pair of different brand but same 3-3-3-8 CL3 specification. I don't think the CMOS batteries are dead because the clock still seems to keep time so I am guessing that something happens that the BIOS code sees as an error maybe during bootup so it decides to re-order the sequence. One doesn't discover this until the next time the CDROM doesn't spin up when a bootable disk is in it. By the way, the CDROM works fine when mounting a CD or ripping one. Clocks will keep time even with voltage quite low. Batteries are cheap enough, as little as $2US for a card of 5 or 6, that they should be replaced, or at least checked with a voltmeter, if ever there is any indication of a problem that might be CMOS related. It's also a good idea when a battery has needed to be changed, to clear CMOS, then restore any desired custom settings. -- "The wise are known for their understanding, and pleasant words are persuasive."
