I am a experienced Debian operator, however new to efi. just starting to work with it.
I am currently trying to install my system with efi boot.
When I downloaded the Debian 10.ISO file and used for install, it initially let me select efi file format from the list when manually partitioning disks.
However, all of a sudden it is not available.
I can not figure out why.
I am changing to efi boot because I may want a drive that is larger then 2 terabytes and also I am trying the run oracle VM and having a lot of trouble About EFI BOOT, when I try to run my virtual machine.
At any rate does anybody know why efi is not available?
I have been working on this for days and have done a lot of searching on google about efi and installing it.
Thanks,
Donald

Re: efi file format not available on install
Did you see this when you did your searches ?
https://wiki.debian.org/SystemVirtualization
================================
https://wiki.debian.org/KVM
I suggest at least trying this, but I am no expert at all, and since yours is a VM, I can see how it may need a different approach,..From: https://wiki.debian.org/GrubEFIReinstallProblem2: EFI boot entries disappear after reboot
The uefi firmware did not create a proper boot entry in NVRAM. This has been seen in a Lenovo Thinkcenter M92Z. The symptom for this will be a missing HD path after the debian entry in the efibootmgr --verbose output. --- read the entire page---
Another suggestion,or hint, you might want to consider using something besides "Oracle", that is a problem within a problem, there are better VM software, EG: QEMU /KVM,... but any way it is your choice,I am trying the run oracle VM and having a lot of trouble About EFI BOOT, when I try to run my virtual machine.

Re: efi file format not available on install
Perhaps the installer is not booted in UEFI mode, switch to a console screen and check for /sys/firmware/efi — that will only exist if the system is booted in UEFI mode.sodcore wrote:At any rate does anybody know why efi is not available?
Make sure that UEFI is enabled and "Legacy" mode (CSM) is disabled in your firmware ("BIOS") options.

Re: efi file format not available on install
What do you mean exactly by "efi file format" ? An EFI system partition (ESP) ?sodcore wrote:When I downloaded the Debian 10.ISO file and used for install, it initially let me select efi file format from the list when manually partitioning disks.

The Debian installer offers to create an ESP only when booted in (U)EFI mode, not in BIOS/legacy mode.
You do not need EFI boot to use drives larger than 2 TiB. You need GPT partitioning. GPT can be used with BIOS too. You can select GPT when doing an expert install.sodcore wrote:I am changing to efi boot because I may want a drive that is larger then 2 terabytes
Re: efi file format not available on install
I had to boot in efi mode to make it work.
Thanks.
I will post if I have futher problems with efi boot mode install for system. Not on the vm.

Re: efi file format not available on install
I am trying to sign my uefi security keys with mokutil for my oracle vm to work correctly.
I am not sure if I need UEFI security enabled.
I get an error if I try to turn them on with or with out the the keys being loaded.
DO I need the keys enabled to sign the keys and if so how do I install the system with it on.
I keep getting errors that the EFI files are not there.
Thanks,
Donald

Re: efi file format not available on install
Please open a new thread for that problem, it is off topic here.
Be sure to search for a solution first though, for example https://gist.github.com/reillysiemens/a ... d79b2182a4
