Mint thinks I have EFI BIOS; I don't -- Trouble; Help needed

Post by markfilipak »

I've searched and found plenty of articles about how to get into EFI mode. That's not my problem.

I think that Mint THINKS I have an EFI BIOS, but I don't. What would cause that?
Note

Code: Select all

mark@mark-Lenovo-V570 ~ $ ls /sys/firmware
acpi  dmi  efi  memmap
mark@mark-Lenovo-V570 ~ $ 
So '/sys/firmware/efi/' exists. Is that the indication? What is it about hardware or process that would cause an install to make such a mistake?

Note: '/dev/sda2' is not clean and I don't know how to fix it.

Note: My BIOS settings are as follows:
1 Information
1-1 Product Name = Lenovo V570
1-2 BIOS Version = 44CN43WW
1-3 KBC Version = 44EC29WW
1-4 Lenovl SN = WB02836788
1-5 UUID Number = 29E7DDC0-CB7A-11E0-80EC-B2DBD19D08CE
1-6 CPU = Intel Core i5-2430M CPU @ 2.40GHz
1-7 System Memory = 6144 MB
1-8 Hard disk = TOSHIBA MQ01AB - 1000 GB
1-9 ODD = HL-DT-ST BDDVD - ATAPI
2 Configuration
2-1 System Time
2-2 System Date
2-3 USB Legacy = [Disabled]
2-4 Wireless = [Enabled]
2-5 SATA Controller working mode = [AHCI]
2-6 Power Beep = [Disabled]
2-7 Intel Virtual Technology = [Enabled]
3 Security
3-1 Set Supervisor Password
3-2 Set Hard Disk Password
4 Boot
4-1 Boot Priority Order
4-1-1 ubuntu
4-1-2 ATAPI CD = HL-DT-ST BDDVDRW CP40NG10
4-1-3 USB HDD
4-1-4 USB CD
4-1-5 ATA HDD = TOSHIBA MQ01ABD100
4-1-6 Windows Boot Manager
4-1-7 PCI LAN = Realtek PXE B03 D00
4-1-8 ATA SSD
4-1-9 USB FDD
Thanks!

Thank you, slipstick. That just about puts a lid on it.

I do not have an EFI BIOS. I need to reinstall Mint. I don't think it will make any difference. Do you have any advice regarding re-installing Mint? I assume it will wipe everything out... This is going to be painful.

I bet that, after I re-install, Mint will still think I have an EFI BIOS.

You better start thinking that, too. Because you do have UEFI. Why you are trying to deny it is beyond me.
Run efibootmgr, see for yourself. Below is output on an EFI machine.

Code: Select all

 efibootmgr 
BootNext: 0000
BootCurrent: 0004

But this would seem to indicate that you don't ?

The output of efibootmgr indicates clearly the box is booted in UEFI mode, there is no doubt. (Not that there was before.)

I don't think re-installing will change anything, but if you are determined to do it, I have heard that a program called Aptik is a good way to save your configuration, etc. for reinstallation.

Just a little semantical remark, to hopefully avoid confusion in the future:
There is no such thing as EFI BIOS. Your machine uses either (U)EFI or BIOS; not both. Calling it EFI BIOS makes things less clear.

I booted in CSM mode, the same box, now the output is different.

Code: Select all

efibootmgr 
EFI variables are not supported on this system.

Indeed. Point well made (and taken). Thanks, M.

Mint does not think, efibootmgr displays the boot order only when booted in EFI mode.

BTW, this is not funny any more.

Mint THINKS I have an EFI BIOS, but I don't. What would cause that?
2-3 USB Legacy = [Disabled]
Set it to 'enabled'.

It was 'Enabled' when this conversation started. I set it to 'Disabled' when slipstick suggested it. Note that 'USB Legacy' IS NOT the switch between UEFI and BIOS. It is to maintain support for legacy keyboards and such. However, I will set it back to 'Enabled' to comply. I will return and add a PS with the results. This will take a few minutes as I need to test it with both 'mintstick' created USB stick and 'unetbootin' created USB stick, and that will take some time.

PS: I have run the following tests with the results indicated.
'unetbootin' made USB stick with 'USB Legacy' BIOS setting set to 'Disabled' -- Result: BIOS does not 'see' the USB stick.

'unetbootin' made USB stick with 'USB Legacy' BIOS setting set to 'Enabled' -- Result: BIOS 'sees' the USB stick, but boot fails (black screen) without message.

'mintstick' made USB stick with 'USB Legacy' BIOS setting set to 'Disabled' -- Result: BIOS does not 'see' the USB stick.

'mintstick' made USB stick with 'USB Legacy' BIOS setting set to 'Enabled' -- Result: BIOS 'sees' the USB stick, but boot fails (black screen) with message: "Error: File '/boot/' not found".
Also note: The computer has a Phoenix BIOS and it is identified as such. It does not have (U)EFI. Why the Mint installer thought I had EFI when I installed Mint remains a mystery and it is probably a bug in the installer. I am pursuing this issue at github.

Yes, this is annoying but mainly the fault of manufacturers who, for some stupid reason, continue to refer to it themselves as "Bios". I guess they think their customers are too stupid to learn a new term.


@markfilipak,

No doubt about it -- your machine does have UEFI firmware! (Manufacturer is just calling it "Bios" -- see above.)

Are you having problems booting into Mint or Windows? Or was there some kind of other problem that made you think that computer wasn't UEFI-based and that UEFI install of Mint was the wrong way to go?

Did you in fact already install Mint? (Based on output already posted, I'm assuming you did.) If yes, boot into it and post back with output from the following commands in a terminal.
  • List full hardware specs of machine with this command:

    Code: Select all

    inxi -Fxz
  • Show current partition structure on hard drive(s):

    Code: Select all

    sudo parted --list

FYI, there are a couple of other threads on this same problem by the OP which will give you info on what has been tried:
