...  as well as with GRUB2 (though IMHO with some added complexity) once you are in the bootmanager you can chainload *everything* or *nearly everything*, whilst ...

Clover supports GRUB2 out-of-the-box.
So it does also kind of semi support its sibling grubfm by a1ive.
You just have to rename grubfmx64.efi to grubx64.efi and copy it to [FOLDER_3] like

    EFI/GrubfmFaked/grubx64.efi
    
and move [FOLDER_3] to "USB_ESP"/ like folder 1 and 2 previously.

@ relynx

 

With all due respect I kindly suggest you to open your own Topic to talk about all details of your procedure, and there answer questions related to it. And please stop hijacking this topic.

 

Hijacking a Topic, unnecessarily disturbes and create confusion to other readers.

 

You can be sure I will read your Topic, as I can boot from my grub4dos menu.lst or from Ventoy directly to my full installed Linux Mint or Linux Lite (both Ubuntu derivated) VHDs located into a HD partition, to try your procedure and I will let you know there if I have any questions.

 

Best regards

 

Your friend

My very appreciated friend, I'm terrible sorry for hurting your feelings. :D

It seems to me that lately you are becoming very sensitive  (maybe it is caused by age).  :buehehe: 

 

If I understood fine one of your previous comments, your proposed approach includes the use of grub4dos, so far in my experiments only successful result not using an auxiliary USB device to boot, was when booting AIO_BOOT directly from grub2 MBR disk first active primary FAT-32 partition the CloverLegacy into it.

 

I haven't tested so far booting from grub4dos MBR disk and chainloading to AIO_BOOT grub2 located on first active primary FAT-32 partition, but it is very easy to test that, all I have to do is change the MBR, edit the menu.lst and reboot.

@alacran: Being sensitive definitely isnt caused by age. I should know, i'm one of those types. people have to be very careful what they say or do around me, because how i'll react in any given moment is unpredictable.

To my knowledge, Wonko has never revealed his age. His real name is known, a public records search wouldnt be very hard. my guess is high 50s to low 60s. That he is a grouch only makes him seem older.

@alacran

Well, I am - admittedly - an old, grumpy, bastard :w00t: :ph34r: since many, many years, I don't think I became any more sensitive lately, most probably it is just a matter of a different level of ability to cope with rudeness, or, if you prefer, what till a few years ago I simply ignored, now I prefer to talk about openly.

 

I would say that with age I increased my directness/straightforwardness.

 

@anonvendetta

Good guess.   :thumbsup:

 

@relynx

Good to know. :)

...

Pardon me, but the topic title reads "Testing UEFI booting on a only Bios PC".
Please kindly depicts which of my posts deviates from the said topic?

Anyhow, it is your thread, and I'll respect your rules, if you rather prefer holding a monologue.
But to abide from future disturbances may I suggest you to choose the topic title accordingly
or at least put a disclaimer in the first post something like
        "... subjects ONLY to Windows grub4dos AIO_Boot ..."
?

No issues whatever, everything you posted is AFAICT, appropriate, interesting :worship: and on-topic, or at least as on topic as my own posts/comments..

 

alacran evidently is in a bad period/bad mood (or - alternatively - you and me are both into one such state of mind :dubbio:, I love coincidences ;)).

 

Anyway, last time I checked and AFAIK, he is not an Administrator or Moderator of the board, so his comments and suggestions on what you should do are only personal opinions.

DUET 32 or 64-bit can be used instead of CLOVER. Here is a video of how I run WinXP 32-bit under UEFI DUET 32-bit (IA32) on old PC x86 Thin Client Igel 4210 (VIA C7 CPU, AWARD 6.00PG BIOS):

@reboot12: The DUET bootloader looks like your screenshot, but without the IBM logo. How did you get it in there?

You have to compile the DUET from the sources by inserting your logo: Custom logo on UEFI boot screen
 
Here is my DUET IA32 with IBM logo: FAT32_IA32.zip

@reboot12: I used (years ago, with Windows 7) the x64 DUET linked to here:

 

http://www.rodsbooks.com/bios2uefi/

 

That DUET file is no longer available, and it doesnt work right on my current PC anyway. It worked great on the laptop I had then, though. I still have the archive for it laying around somewhere.

 

No idea where to find the source code, or if it's still available. Probably on GitHub or GitLab.

 

Edit: When I say that it doesnt work now, i mean that it doesnt see my NVMe SSDs. Or even my SATA SSDs, sometimes. I can usually get it to boot, but not always. I'm tempted to try Clover again, it seems to be superior, and more compatible with recent hardware.

 

Edit 2: i just tried booting it from a flash drive. it fails to boot multiple times, never a success. Maybe it's because i have 64gb RAM? i know it worked when i had 16gb, before i upgraded.

You have compiled different DUET x64 versions in this topic: UEFI DUET Installer - REFIND boot manager
Or try make USB flash drive from this: Tianocore Uefi Duet Installer
or download from this: link in the description

 

P.S. Win7 64-bit can be run under UEFI class 3 without CSM using the UefiSeven loader - this even works with WinXP 64-bit (amd64):

UefiSeven: Easily boot Windows 7 on UEFI class 3 devices

 

WinXP 64-bit test UefiSeven in pure UEFI and UEFI+CSM

Boot WinXP SP2 64-bit from UEFI class 3

Hijacking a Topic, unnecessarily disturbes and create confusion to other readers.

 

You can be sure I will read your Topic

 

 

Note for self:

avoid posting (polite) suggestions on alacran's threads, as they will be likely ignored, whilst the rest (comments and opinions provided for context) will be nit-picked to death.

 

Technically, the solution to avoid such grievances is to write an abstract in one single post of any thread and to clean it up over the time, like Alacran has started anew in post no. 355 of the "Grub4EFI" thread.
