Can't get Rufus to work for *UEFI only* on 32bit (I'm probably LOST here)


(Note: this isn't a 'dup' of my other tablet install thread)

I'm trying to learn to create=burn bootable USB pendrive=stick.

Rufus was suggested. (I chose p=portable version; probably doesn't matter)

Which Partition scheme and target system type should I choose?
MBR or GPT; BIOS-UEFI or just UEFI?

Rufus seemed to suggest non-BIOS (uefi-CSM?) UEFI (only): see pic.
BUT, then *ALL 32bit* .iso (yes, Mint too) get this Unsupported ISO error:
https://superuser.com/questions/7423...n-gives-errors

So, I moved from 32bit XP netbook to 64bit Win7 laptop (non-UEFI)
and UEFI-only wrote some
but still fails with this: https://github.com/pbatard/rufus/issues/170
So, I can't create=write=burn a 'good' UEFI USB with Rufus.

Also, I was missing GPT (vs MBR) option, when running on 32bit.

I also fell down the rat-hole of choosing dd instead of iso
because it suggested trying DDmode IF (iso mode) doesn't "work", meaning "boot" I think.
Also, choosing dd-mode will force XP to write a 32bit .iso in UEFI-only! Is this 'bad'?
Choosing dd-mode initially, only allowed a .img file (no! .iso)

Sorry I'm sooooo LOST. Patience please

I can test-boot UEFI-only USB in VBox, IF I could ever get Rufus to work.

Sorry, I disagree. Other thread is about tablet boot; this is about Rufus writing.
Understanding the options Rufus gives, esp. running Rufus on an old XP 32bit netbook (and Rufus's MBR vs GPT options, on a non-UEFI Win7 laptop), has nothing to do with: getting a Win10 tablet's UEFI?BIOS to see and boot from a USB device (when ?tablet? may need ?signed? UEFI-only). The XP 32bit netbook has 3 usb ports, kbd, touchpad, &power-connector; the Win10tablet has one microUSB port, for only 1 of: power, USBstick, kbd, mouse. I'll probably end up returning the tablet; if I do, does that mean I can't use Rufus any more? No. Is EFIshellPrompt == Rufus? No.

Probably Rufus won't work for what I want. (And it doesn't run on Linux nor do multiboot)
Still, I'd like to learn/understand how to use Rufus, for any&ALL situations, UNrelated to any 1 tablet. And, the other thread is messy enuf already, without a Rufus-issues tangent.

My Conclusion: no one knows how to create the 'right magic' UEFI usb.

Some of these windows 10 tablets have an odd deal about the loaders. Did you check on this issue? Some need a (I forget) 64 bit loader to run a 32 bit os or the other way?

Can't say that I fully understand what you are asking or doing.

If one took an iso file of ubuntu and used a working dd command to a usb drive it should result in a bootable (on some systems at least) usb drive. I've not tested dd4windows on any modern linux. Last time I used it was on a floppy.

I have always selected "MBR partition scheme for BIOS or UEFI" and iso mode. This usually works on both efi and non-efi system. Basically what it does is formats the usb as fat32, installs syslinux for booting non-efi systems, and extracts contents of iso to the usb.

My Conclusion: no one knows how to create the 'right magic' UEFI usb.
First, I would like to say that, from experience, UEFI does not work in 32-bit. I'm not Rufus expert, but whatever software you use, you cannot make a bootable USB for a 32-bit OS with UEFI compatibility. From explanation on Rufus website, the Windows on which Rufus is running can be 32-bit, but the iso you are burning must be 64-bit UEFI compatible, obviously.

Now, for that "right magic" part. Since you mentioned "doesn't run on Linux", actually, if you are using Linux, you can make a bootable UEFI USB quite easily. There are several ways, but probably the easiest way is to use the dd command:
Code:
dd if=PATH_TO_ISO of=/dev/sdX
sdX is replaced with the appropriate device (e.g. sdb, sdc ...)
IMPORTANT: the iso must be a UEFI compatible OS.

If you only have Windows and Rufus, just ensure you have an iso for an OS which is 64-bit and UEFI compatible and that you choose GPT.

Thanks #5&6. Tried UDF. Tablet wouldn't even see the 'MXT' (usb pendrive)
('Win7' non-uefi laptop won't boot GPT=UEFI UDF, of course, since non-efi bios
Tried MBR BIOSorUEFI UDF combo Worse: laptop booted internal hdd Win7 when I chose the MXT, and Win7 is going to spend the rest of the day M$updating itself)

So many combinations (of choices in Rufus) to try
And, I'm betting, NONE are what the evil Tablet wants


Completely OT st00pid?: linuxmint18.2xcfe64bit.iso on the Win7 laptop (NOT the evil tablet!)
it (live, again on laptop, NOT tablet) asks for F1 to login; username mint, <enter> for no pwd
isn't valid. So, how do I login?
