Re: [SOLVED] USB image - Access Denied error

Sorry OP, my posts in this thread are irrelevant — I failed to read through the thread properly before answering and didn't appreciate that you're trying to boot a USB stick rather than an installed system.

Apologies for the noise.

But thank you for trying to help.
Just unlucky that my first installation is fraught with so much difficulty.

Hi

I do not know if the following video is relevant https://www.youtube.com/watch?v=jw_ZNgEn874 . Apologize if not. Is CSM disabled ??

Have a nice day

Re: [SOLVED] USB image - Access Denied error

In the meantime I have found out that the BIOS Superuser password of the PC is set, which prevents me from disabling Secure Boot.
(I bought the PC secondhand.)

So I have three options:

  • Disable Secure Boot. I must first unset the password by removing the CMOS battery.

  • Find a way to boot Devuan.

  • Use Debian.

I can't change the BIOS settings because the BIOS is password protected.

I have been warned on the Lenovo forum that removing the battery won't clear the password and risks blocking me out of the PC.

My web search lead to
https://www.cocosenor.com/articles/comp … aptop.html
where at least the first option seems quite safe to try.

EDIT: duly edited. Thanks @Camtaf.

I booted from a Debian USB into grub and tried to boot Devuan in the other USB drive:

Re: [SOLVED] USB image - Access Denied error

Hi

The interesting part is that you can boot debian. But Devaun and Debian are using the same secureboot key as far I know of.

So what is the difference ??
Another option is to install Debian and then migrate to Devuan.
Or install Debian (or even Windows) and run Devuan in a virtual machine.
Or get another motherboard for the machine.
Maybe try to reset by removing the battery. You will most likely loose nothing if you have backup of your data. The problem might be loosing encrypted partitions by a reset. But backups solve that problem..

That is what I can think of right now

Re: [SOLVED] USB image - Access Denied error

I just had an unexpected miracle when trying a variation of booting with both the Debian + Devuan USB sticks.

With both sticks plugged in I selected USB on the BIOS Select Boot Device screen, which gives no choice of USB drive when multiple are plugged in. The blue screen came up, I thought I was looking at Debian, but no, I did a double take and  it said Devuan !!!!

What was different ? - This was Chimaera netinstall, created with copy/paste.
(By copy/paste I mean: Format USB as FAT32, then copy paste the contents of the image via drag & drop.)


A recap of what I have tried :

  • [which image + USB] | [which write method] | [result]

  1. Beowulf desktop-live | AnyBurn, Unetbootin-windows, dd-Windows | Secure Boot Access Denied error

  2. Chimaera desktop-live | AnyBurn, Unetbootin-windows, dd-Windows, copy/paste | Secure Boot Access Denied error

  3. Chimaera desktop-live + Debian | copy/paste | BIOS loads Debian, grub: Secure Boot refuses to load Devuan

  4. Chimaera netinstall | AnyBurn, dd-Windows, copy/paste |  no error, no load, BIOS re-presents  Select Boot Device screen

  5. Chimaera netinstall | Rufus |  Secure Boot Access Denied error

  6. Chimaera netinstall + Debian | AnyBurn, dd-Windows, copy/paste  | BIOS loads Devuan installation menu


Just to be clear: The only successful attempt requires the Debian USB to be plugged in but it is not loaded or used in the process.




I have not yet attempted the actual installation.

Re: [SOLVED] USB image - Access Denied error

Wow, that is weird. But then again, I have yet to see two uefi implementations that act the same way. If you install from there, be sure you know which drive you are installing to.

If you search at youtube for 'Lenovo T550 replace cmos battery' (or factory reset) you will find some videos showing you how to do it. If you do it, keep track of which screws go in which holes. They are not all the same.

Re: [SOLVED] USB image - Access Denied error

It looks like I don't need to disable Secure Boot now. I definitely won't be screwing with the laptop myself.

I've used a Linux desktop for 15 years but never done a system installation. Hence it had been suggested to me to use desktop-live.

I'm sure I'll need help with the netinstall here. It's my only PC.

Re: [SOLVED] USB image - Access Denied error

Have a look at https://www.devuan.org/os/install and drill down the links. Especially https://www.devuan.org/os/documentation … all-devuan may be useful. Unfortunately it only shows the legacy grub installation, not the efi version.

Re: [SOLVED] USB image - Access Denied error

@Élisabeth, the ISO file is supposed to be put onto a USB memory stick to reside from the physical block 0 and up on the USB. Copying onto a partition is not the right way.

To achieve that on windows seems unduly complicated but it should be possible, and in particular I believe dd-windows may be used for it. The important point is that the USB becomes an exact copy of the ISO from its block 0 up to whatever size the ISO is, and then the USB stick can have whatever on the blocks after that. (Somewhere I saw the suggestion that "the disk as a whole" is Partition0 with dd-windows)

The first partition on a disk starts some few blocks in and the first few blocks contain the partition table. The ISO file starts at block 0 and includes a partition table for its partition layout, which includes an EFI partition and a CDROM partition. All that must be put onto the USB memory stick from its block 0.

Note that when you "format the USB as FAT32" you actually create a single first partition on that USB, and then copy&paste just copies the ISO file to be a file on that partition. Doing that is not the right way. Again, just to have it repeated three times: you'll need to copy the ISO onto the USB stick as a whole to become the exact memory image of the USB stick from block 0 and up.

Ralph.

I absolutely agree. I just tried this tip out of despair.

But, if you look at my post point 4, the PC does not boot from the Devuan USB regardless of whether I use dd, AnyBurn or copy, unless the Debian USB is in the other slot.

Re: [SOLVED] USB image - Access Denied error

Ok; afaict AnyBurn has the "Burn image file to disc" button to master a USB stick from an ISO file, and if you used that, then the USB stick is mastered correctly.

The next would be to get an overview of which boot options the UEFI startup code sees. Apparently there is a windows' program named bootcfg to use for that.
https://docs.microsoft.com/en-us/window … ons-in-efi
If I understand correctly, you would start an Administrator command line shell for running bootcfg, and (from the doc) the applicable command seems to be bootcfg query. You should try that with the mastered USB in place, and perhaps also with the mastered Debian USB in the secondary place.

Please drop the resulting output here for us to look at.

EDIT: then I saw that apparently bcdedit is a replacement bootcfg... so maybe you already posted something. Though in that post it only shows the windows boot entry, so maybe you will need to repeat that with the mastered USB in place. My random doc pointer for bcdedit is
https://docs.microsoft.com/en-us/window … ds/bcdedit

EDIT2:
and this one is useful for bocdedit /enum variants
https://docs.microsoft.com/en-us/window … edit--enum
.. perhaps a good list from

bcdedit /enum osloader

.. or maybe

bcdedit /enum all

I used Create bootable USB Drive with the HDD option.

No, that's not the right thing. Doesn't it have the "Burn image to disc" option? All else will try to mess with the image.

How did this repsonse get into my post ?


AnyBurn has this option. But it can't be used for USB. I immediately get an error: Aucune unité de gravure detectée (no engraving unit detected)

Re: [SOLVED] USB image - Access Denied error

sorry about editing your post.. must be tired...

Ok. so AnyBurn is no good, then. Possibly dd-windows? but you must make sure to select The Whole usb stick and not any of its partitions.. except that possibly dd-windows uses the name "partition0" for the whole disk (again I've picked that idea from my web searching)
