Hi, All-

 

I'm here to ask for a little help with the dreaded UEFI...

A friend just gave me on old HP Omen gaming tower, model 870-244.

As expected, I am unable to get to the BIOS- it keeps intercepting that.

Oh, I do get various boot screens but it's all HP UEFI stuff.

I can get so far as having a blue BIOS-y looking window that offers

UEFI Boot Sources or Legacy Boot devices. But It won't actually

let me select Legacy devices. I have a DVD in the optical drive

with Linux Mint 22, and I can hear the drive head sound (twice)

each time I boot. This is about a 2018 computer build...

I would sure like to get a look at the BIOS to see what devices

boot order is set up.

 

Upon further playing, I disconnected the Win 10 HDD and substituted

an old 120GB SSD I had laying around. Initial success- I was able to

boot into 2 live DVD sessions of Mint 22, access the net via FF, etc.

The mobo was able to boot to my DVD with no BIOS fiddling.

 

Then things went sour after I used gparted to move some partitions

around on that drive. I was getting ready to install MInt 22. Now

the tower can't utilize that drive, not can it do anything with a brand

new, out of box, unformatted 1TB HDD. Not can it use another 32GB SSD

I had on hand. So apparently I have hosed... something... At least the mobo

can 'see' all of these drives but they are now unusable for a live DVD

linux session.

 

BTW after that happened, I moved the 120GB SSD over to another

computer and used gparted to start from scratch- reformatted,

set up an extended partition with swap and two ext4 in it, plus

three other FAT32 primary partitions. I formatted the drive MSDOS...

I think the linux partitions had previously been ext3, if that makes

any difference... No help.

 

So as a test, I hooked up the original WIn 10 HDD and was able to

boot into windows. This tells me the mobo and power supply and RAM

etc are all still good. That is where it stands. I'm confused, frankly.

Open to suggestions. What would you suggest I try next?

 

My friend sanitized Windows and also set me up as an alternative

user with admin privileges before giving me this tower. Removed

all personal files, defragmented Windows, did general cleanup.

Windows seemed to be working fine, other than being so very

tediously slow to boot up (remember, HDD on board).

 

Thanks, guys- I would really appreciate any help you might send

my way...

BTW the specs on this box are (roughly):

 

3.6GHz dual I-7 Intel processor, 16GB RAM installed...

Win 10 installed on original HDD... Something like a 240GB drive...

Failed to open EFI/Boot/mmx64.efi - Not found
Failed to load image??: Not found
Failed to start MokManager: Not found
Something has gone seriously wrong: Import_mok_state() failed: Not found

 

One update: After struggling with a torturously complicated 'boot menu', I did find

that pressing/holding F6 at power up got me to where I could F10 to get into the BIOS.

A necessary prior step is to hit the Esc key to get into their 'startup menu'.

Whew! But changing the boot order does not help. Despite moving the DVD

drive to the top of the list, I still get the error message above. This box could

formerly boot into a lived DVD session, now it consistently refuses to do so and

is complaining about not finding a bootable image?

 

I'm wondering if I might be dealing with a flaky DVD drive. Previously I had not been

getting the mobo to recognize a DVD copy of Mint 20.1. I then downloaded and burned

an image of Mint 22 and that did it- booted into a live DVD session on Mint 22- twice.

Then came the hard drive problems, possibly self-inflicted?

 

I'm now thinking maybe I burn an image into a flash drive and plug it into a USB port?

USB is in the boot order...

 

Edit: Usb stick with Mint 22 also fails to boot. Same error message.

 

Update: Changed from Secure Boot to Legacy Boot in the BIOS under Security.* Mint 22 appears to be installing from the USB stick now. I did, however, get a warning that no efi partition could be found (or something to that effect). Warning that the installed OS might not be bootable. This has been a pitched battle, every step of the way. Need I say that I hate UEFI? Clearly they worked hard to make this as difficult as possible... OS installed fast enough, and appears to be repeatably bootable at power up. What a freakin' ordeal this has been!

 

*I will have to recheck whether dropping Secure Boot has affected my ability to boot into Win 10 using the original HDD that came with the tower. But then the only anticipated use I can foresee presently for Windows is to possibly be able to finally use a couple of flat bed scanners that are Windows only compatible. They have been gathering dust for close to 20 years now... 🔓

 

After ~17 years playing in the Linux sandbox, I may have gotten a little better at 'self help', figuring things out on my own. 😉

Ok, your problem is 99% secure boot. Just as expected, it boots fine after removing secure boot. Secure boot is made for windows but you can get it to work under linux if you don't mind wasting time for a useless feature. https://www.makeuseof.com/what-is-secure-boot-how-does-it-work/

 

You had me thinking it over until you mentioned Secure Boot and then I knew exactly what your issues were.

UEFI works great on linux so that was not your issue at all. You may as well move to it as legacy has its limitations (2tb boot drive and such).

I was thinking the same thing as I read through this.  If Clutter had just turned off SecureBoot, this might have gone quite smooth for him.  No doubt it was difficult to locate in an unfamiliar UEFI/BIOS setup.  Moving the EFI partition was the fatal blow, however, and all hell broke loose.  If EFI had been left intact, it was still easily salvageable.  Never move an EFI partition that's already on the disk.  It's okay to create and install an EFI partition on a new and unformatted disk.  Don't move THAT partition.  There are exceptions, but for those like myself, it always breaks something and just creates WAY more work than necessary.  Leave EFI partitions alone.

Clutter has already enabled Legacy mode and seemingly installed Mint22 with a MBR/BIOS config.  He'd have to start over....turn off Legacy/COSM boot, and reinstall Mint with a GPT/UEFI configuration.  Since it's a brand new installation, presumably without heavy customizations already made, I'd probably do that; if only for the reason to gain experience with UEFI, as BIOS will soon go the way as 32-bit OS....specialty cases only. 

 

I agree with SB....UEFI is better.  UEFI is the future (present?!) and it's actually no more complicated than BIOS.  It's that damn SecureBoot that gives UEFI a bad reputation.  Thank Microsoft for that (shocker!).

 

It sounds like you resolved it yourself, Clutter, but if you wanted to have a go at it again for the added experience and knowledge, just disable SecureBoot and Legacy Mode in the UEFI.  Your LiveMedia should install without a hitch....with all the benefits of UEFI.  FWIW...

Thanks, Guys-

 

At this point, much of what you're saying makes intuitive sense. No, I don't have all

that much emotional investment in the currently installed Mint 22 OS. Just a good

chunk of my time, banging my head against Secure Boot, which I had kinda sorta

heard about already. So I didn't really expect it would be all that smooth an

operation. The key stumbling block was the tower didn't come with the user

manual- thus a lot of unnecessary fumbling to get at the BIOS. I finally found it

based on a hint from the former owner ("maybe F6?") but I really had to resort to

all kinds of variations, repetitively.

 

I've lost nothing really, so far as whatever Linux OS and personal files were on the

120GB SSD. I had already migrated those contents to a bigger SSD, which lives on in

one of my antique Dell workstations. I'll play with this as is for a few days, even adding

stuff, but am not averse to starting over. I haven't taken time to go back to the original

HDD to see if I have in any way hosed Win 10. (through my BIOS tinkering)

I did receive an "Emergency boot disk- Newest version- compatible with all versions

of Windows"- along with the tower. And some speakers.🤭

 

Compared to my old Dell boxes, which are nicely laid out with everything very

accessible, this 'new' HP tower is a rats nest. Looks like I would have to remove

the metal shroud around the big video card to have enough hand room to even plug

a 2nd SATA cable into the mobo. And that is held captive by part of the wiring harness.

But cutting a tywrap or two and unplugging the video connector should make room

enough to pull that out. Anyway, free is a very nice price! And it comes with a

higher CPU speed and double the RAM of my Dells, maxed out at 8GB. Also a much

more powerful video card. Former owner mentioned it might be expandable to 32GB

RAM. Without reading the manual, I'm not yet sure of that. I do see 4 slots in two colors.

But sometimes each color accommodates a slightly different style RAM. So TBD...

I did download 'something' from the HP site. I'll have to go over it and see what's in

there. Heading straight for Specifications.

 

So now I'll just play, erercise it online with my usual emailing and web surfing,

usually with FF bloated with dozens of open tabs- LOL! Very helpful comments

above. I'll have to fully digest all that info. Then I can tell better if a redo would be

the better path.

It means that the colored pair is a dual channel set and that you should install RAM as a pair to take advantage of it. Basically match the colors if you are only use two slots.

If the mobo has four ram slots and you are only installing two sticks of ram the manual should tell you which slots to populate first. Worth checking up on as some mobos are funny about ram installs. 😎

Late to the party but I have worked with HP for years and generally if secure boot is off they will install LM using a UEFI config and run fine. They also have the capacity to run in Legacy mode but no need.

I never use DVD Live setups anymore as USB thumbdrive is faster and easier.

Aside from switching off secure boot and making sure the machine will boot first from USB I never mess with the UEFI/BIOS settings. I just take a GPT formatted blank SSD and let Linux Mint do its thing.

Lenovo laptops are also pretty good in dealing with either Legacy or UEFI setups.

So obviously running GPT and UEFI. Linux Mint was installed here from a LIve USB just choosing to wipe the disk and allow the defaults.

More great info, guys. Thanks! I was aware of the RAM socket color coding in terms of

'channels', also RAM type compatibility sometimes differing between the two colors.

 

Thanks for the reminder about GPT. I had reflexively reformatted the drive as MSDOS.

Looks like GPT is the better choice. I'll remember that in the future. Just another bad

habit I need to change. Same applies to burning DVD .iso images. Just a habit...

 

I did install Mint 22 using an image on a thumb drive. Boy, was it ever faster. This was my

first test drive of Mint 22 and I'm favorably impressed. The Mint guys are still doing a

great job. I still have one or two boxes with Mint 20, and several more with now obsolete

Mint 17. These are infrequently used. Mint 17 is no longer supported. I need to update

those towers but had been putting it off because of the time consuming task of

preserving all my files. Clutter has accumulated a lot of, ahhh, clutter over the years.

Wonderful old photos and such that I want to save...

 

I know already I'm going to be very happy with this gift/windfall. The HP tower is fast,

especially with an SSD hooked up. It spent its early years running from an HDD

using Windows. That combo must have hobbled an otherwise fast machine. My very

positive experience installing from a flash drive has convinced me to go online and

buy a bunch or them, probably mostly 32 and 64GB. They have gotten amazingly

cheap in recent years. I had to move a bunch of files from one flash drive to another

to have an empty media to put the OS image on. Took a lot of time to get that very

slow process completed. I had no empty flash drives on hand...

Going through some of the online info on this HP computer, I found instructions

for socketing RAM. It says 32GB RAM capacity, the type is DDR4-2133,

unbuffered/non-ECC. I guess I'll go shop Ebay and see how expensive this

type is, just for grins. Actually, I'm not at all certain I need that much memory.

Probably 16GB will be enough for me. I never got into computer gaming... 😉

 

My old Dell workstations max out at 8GB. I was therefore excited to be getting my

first ever machine with 16GB installed. And as a 'hand me down'...

I would stick with 16GB if you have it. I have never really needed more than 8 GB with Linux Mint on any of my boxes. Unless you plan on heavy-duty video editing or running virtual machines 16 GB will be plenty.

I have found that the best upgrade you can do in any machine is an SSD.

Agree completely. Ventoy on a usb stick is the way to go as the majority of distros will run just fine from that set up. Easy to set up Ventoy and makes life so much easier once done. There are still some distros that will not boot from a Ventoy + usb set up but not many.

Yup 16 GB of ram is sweet any more is just a waste of money unless you plan on heavy-duty video editing or running virtual machines. Only a handful of  the very latest games can use more than 16 GB.

 

These days ssd's are so so yesterday. Nvme's are the way to go for speed these days and they are stupidly cheap too. 🤭 Ssd's will speed up any older pc and very noticeably too.

I have just retired a pc running a previous generation i7 Skylake cpu + Nvidaia 1070 gpu + 16 GB of ram and it was brilliant. Coped with every game at almost ultra settings. Upgraded as it was stuttering and struggling a bit with Fallout 76 in very intensive activity scenes.

Trouble with flash drives is that they are prone to sudden failure. You might find that a dual socket external drive dock will be a cheaper option in the longer term as it will alow you to utilize any SATA drive.

Per the HP website with motherboard specifications- you can put an M key M2 2280 NVMe Pcie 3.0 SSD on the motherboard.

BTW NVMEs are SSDs. NVME is just a connection type like SATA. https://www.pcworld.com/article/558324/nvme-vs-m-2-vs-sata-ssd-whats-the-difference.html

 

All of it is technically flash memory as they do not use platters.

Most of the laptops I have inherited are too old for NVMe drives. I have one in my latest desktop. However, just about everything built in the last 15 years can use a SATA SSD. Obviously an NVMe drive is the smarter option if possible. I use the term interchangeably with SSD as both are a huge upgrade over a mechanical drive.

It's quite easy and reliable to upgrade in place from Mint 21 to Mint 22. Anything older you have to nuke and repave. I don't have separate partitions for data so I copy anything important to backup and then reinstall. However I have upgraded my oldest Linux Mint system several times now without a reinstall.

Yeah I meant SATA (SATA drives are the larger, 2.5-inch drives that most resemble classic laptop hard drives.) and NVME  (NVMe is primarily seen on PCIe-based SSDs that are built in the M.2 size. Those are the stick drives that are a few inches long and around an inch wide.). Between NVMe and SATA, NVMe SSDs are always much faster.

 

These are quite a neat explanations,

NVMe drives operate over the PCIe interface, which provides multiple lanes for data transmission. That makes them significantly faster than SATA drives, which is the main takeaway here. A typical SATA SSD may have read/write speeds of around 500MB/s, but new NVMe SSDs operating on the PCIe 5.0 interface can hit 14,500MB/s. That’s huge, and you will absolutely notice the difference in day-to-day use.

Quite the interesting topic, faster solid state drives in general. Even I,

not at all a 'power user', have started to accumulate smaller SSD's.

I had two on hand for this recent event. And I do sort of think of them

as being just a bigger, klunkier sort of 'USB stick', although there is

really no comparison to a SATA interface's speed. Hey, you can

actually install an OS into a thumb drive. I never have. Seems to me

that OS would be fairly machine specific, anyway. But my recent

experience means I now have an appreciation of how much better it

is to install an OS from a thumb drive image. Now I'm thinking about

CD/DVD as more of a media storage sort of thing. I do love to ply the

used market for the occasional music album or movie. Clutter loves a

bargain...

 

I understand SSD's do have a wearout mechanism. That gives me

pause when contemplating the used market for these drives. Gamers

probably beat the living carp out of this type drive.

 

NVMe is an intriguing new topic for me. I was at least aware that some

users have various super fast little modules plugged directly into mobos.

I will have to learn more about this tech. I suppose we all do owe a lot

to gamers. Those guys may be mostly responsible for the tremendous

growth in PC capabilities- although there are plenty of other 'super

user' types in the mix. Here am I at the opposite end of the PC user

continuum, just an emailer/web surfer LOL! But even I do see and

appreciate such obvious gains in speed coming from solid state drives.

 

I do think my new HP box was quite the windfall. Fastest box I have

ever owned to date. Has a silly dual vertical LED light bar running up the

front panel. It slowly changes colors... 🤩😆 If I get tired of the light

show I can strategically cover this 'amazing spectacle', making due

allowance for a horizontal slit at the base of the vertical DVD drive

and a cutout for the eject button. Also making note that the upper part

of this cover cannot be tape, since the drive occasionally needs to

pop out the top 40% of any such cover...

This is most intriguing. I will look into this sort of thing. It would be great to have

a way to hot plug a SATA SSD externally on a desktop tower. But it uses a USB

pipeline? Anyway I will work on understanding what these can do. Way more

convenient than having to remove all the clutter from the top of the tower

(books, CD, DVD, etc.) and pulling the side cover off. 😉

 

My new HP tower has four USB ports on top, in the front. Thumb drives plug

down into those jacks at a slight angle. Two of the USB symbols say "SS".

I am assuming that's 'solid state' as in SSD? And one of the SS ports has a

lightning bolt symbol as well... BTW the tower also has beaucoup USB ports

on the rear panel.

SS identifies the port as USB 3 (faster data transfer). I think the lightning bolt means it's also a Thunderbolt port but I haven't used that technology.
