#257478 — efi problem

I suspect the GPU is suspect because there are small blocks of pixels 
appearing where they aren't wanted.
I'd like to re-install the OS as I've got copies of everything I think.
Just to see if it's maybe a driver issue.
Thing is I can't get the f12 options screen of the PC to let me boot 
from a CD in this EFI mode what's grub done.
How can I boot from CD in this EFI mode?

Without knowing the make and model of the computer, it is difficult to 
offer specific advice.


When you power up the computer, there should be a hot key to enter the 
System Setup utility (or whatever it is called on your computer).  Press 
it.  Then find whatever screen(s) are used to enable boot device(s). 
You may need to create an entry for the optical drive and/or enable 
booting from the optical drive.

You try other keys besides F12. You tap them repeatedly after
turning on. You try them in combination with Escape. There
are usually a number of features on different keys, like:

F1        System Information
F2        System Diagnostics
F7        HP SpareKey
F9        Boot Device Options
F10       BIOS Setup
F11       System Recovery

Cheers,
David.

If you can tell us what model of motherboard this is, we can maybe
tell you what key. If you have another Debian machine somewhere,
use dd to write a netinst.iso to a USB stick and boot from that?

Many old machines respond to DEL key tapped repeatedly on first booting up

F1 / F5 / F7 are all possibles: F12 is usually for a one time boot

You may need to set priority order for BIOS/MBR/Legacy and UEFI boot order
separately.

Good grief!  Use etcher or dd to copy it to a USB flash drive. Or put 
the machine in compatibility mode, and bypass the UEFI.

Are you sure it's supposed to be F12 on yours?

  what does efibootmgr say when you run it from the 
root prompt?

  mine lists the CD drive and if i change the boot 
order to put that first it will boot from that device.

  man efibootmgr

BootOrder says that CD should be tried first. Do you have something like 
"Fast Boot" option in firmware settings (earlier called BIOS)? If so I 
suggest to disable it. Check that boot from CD is enabled there.

If the timeout setting is respected by firmware, you may try to increase 
it to e.g. 10 seconds. Likely 1 second is not enough to spin up CD.

I have no experience with Dell and I am not aware that some kind of 
idiosyncrasy that has to be taken into account.

  yes, man efibootmgr would have told you:


efibootmgr -o 0008,0000,000A,0003,0004,0007,0001,0002


and then reboot.

  of course, if you want the above order different you can
change it as you wish.

  boot current can be ignored for the moment.  check it after
you reboot to make sure it has changed to what you want it to
be.

  boot next may sometimes be useful (see man page).  in your
case using 

# efibootmgr -n 0008

  would set 0008 as the next time (and one time use only)
boot entry.  but if you want this to be a permanent change
you have to set it using the -o option.


  as an example of adding a new one - sometimes grub updates 
wipe out my refind entry so i have to put it back in using:

efibootmgr -c -L Debian_Refind -l "\EFI\BOOT\BOOTX64.EFI"


  and then i set it as my preferred first one:

efibootmgr -o 0,1,5,6,7

  of course my list is different than yours...

Yes, and with no floppy and a deceased optical drive, you
were scuppered. But times change, and there are workarounds.

What's the name written on the front of the computer?
Is the optical drive internal or external?
What /have/ you tried so far? Which keys, what happened?

Cheers,
David.

Install grml-rescueboot

sudo apt-get install grml-rescueboot
Place bootable ISO files in the /boot/grml folder.

Since this is a system folder, the operation must be conducted as
"root". For example, if the ISO is located in the user's Downloads
folder, the command would be:
sudo mv ~/Downloads/<filename.iso> /boot/grml/
Update GRUB
sudo update-grub

(If I'm understanding everything correctly, this is the non-hacker way.)

I just tried it. It may work with a grml CD ISO; I didn't try it. The
code builds the grub.cfg entry correctly, and that works. But grub
refused to boot the debian netinst image I provided.

  i'm sorry for not going back and re-reading everything
(about to head outside for the rest of the day).

  do you have a spare USB stick that will hold the netinst 
image?

  i suspect you may have not copied it simply as the directions
in the installation guide recommends or done something strange
and it may just be simpler to try a USB boot instead.

  that's my thoughts at this point.  hope you will make better
progress on this soon.  :)

No worries. I have USB sticks, CD-RWs, etc. I just did the experiment
to see how well it worked. Thanks for the thoughts, though.

It seems I falsely assumed that, seeing that the package is in Debian,
that it could boot a debian iso. Upon further research I realize that
this is apparently not the case. I guess the key word is "rescue."

How about Ventoy (mentioned here I think by Dan Ritter once) on a usb
stick?
 
But then I think I've forgotten already the problem we're trying to
solve.

Taken into account current size of netinst, I see not point in avoiding 
of iso-scan:
760M debian-bookworm-DI-rc1-amd64-netinst.iso
