[Solved] Debian fails to install on UEFI

[Augiz]

Hello, to clarify the laptop I'm trying to install debian on is Lenovo Ideapad 120s-14IAP.
Basically what happens it freezes on splash screen.

Using Debian 9.5 amd64 architecture, compiled into usb drive with rufus.
On UEFI architecture it just freezes on splash screen (lenovo logo), on Legacy bios it installs, but then its not possible to dual boot.
The very same usb with the very same debian works fine on my other two computers.

Ubuntu and linux mint (from same usb drive) installs just fine and works well on this laptop on UEFI. So the problem must be within debian.

Tried multiple usb drives too - no success.

Thanks for help.

In UEFI mode on your machine, have you disabled Secure Boot and fast boot?

[Augiz]

Yeah secure boot is disabled (if it weren't - debian would just drop warning). There's no fast boot option in bios but on windows settings its disabled.

As I said the screen just freezes on splash screen, which doesn't happen with linux mint or ubuntu on the very same settings.

Please write the technical details of your computer.

Pentium n4200, 4gb ram, 120gb ssd (not emmc), hd resolution. Laptop only has usb 3 ports (maybe thats the catch?). But i only own few usb 2.0 drives. Regardless ubuntu installs so does mint.

Is there a way to install debian on legacy then make it bootable from uefi?

[p.H]

Using Debian 9.5 amd64 architecture, compiled into usb drive with rufus.

In "dd mode" ?

On UEFI architecture it just freezes on splash screen (lenovo logo)

Can you elaborate ? Can you select the USB media containing the Debian installer, then is the GRUB menu displayed ?

Ubuntu and linux mint (from same usb drive) installs just fine and works well on this laptop on UEFI.

FWIW, Ubuntu and Mint support UEFI secure boot. Debian does not (yet).

Is there a way to install debian on legacy then make it bootable from uefi?

Yes.
The hard part will be to set up the multiboot with Windows.

Found this on websearch for debian+Ideapad+20s-14IAP there is a link to an older reddit that explains some BIOS settings that worked on another Ideapad 120s-12IAP

Tried both iso and dd - same result.

Cant find a way to mess up with greyed options - "platform mode" and "secure boot mode" (which is set to custom).

just to be clear that's the system splash screen? the one that appears on boot? so you don't get to the grub menu?

Correct. If I have the "secure boot"="on", the "secure boot status" still stays on disabled and the result stays the same.

Can't see the pictures right now but on some UEFI firmwares you must set a password to unlock secure boot settings.

You did not answer this :
In the UEFI boot menu, can you select the USB media containing the Debian installer ?

I can see usb with debian being recognised from bios boot order screen, and its obviously the #1 on the list.

But you know when pc is loading you get that splash screen with manufacturer logo - "Asus", "Lenovo" or whatever - after which the OS boots right in. So yea I get stuck on that splash.

[p.H]

Do you mean that the "lenovo" splash screen is displayed after you selected to boot from the USB drive ?

[Augiz]

Correct, and just freezes on that.

[milomak]

which install media have you chosen?
