American Megatrends: LEGACY boot not found at all in bios menu (only UEFI)


Hello,

When launching the BIOS American Megatrends, pressing ESC or F8 to boot menu, I can launch and start Linux.

The boot menu says:

UEFI: shell
Windows
UEFI: flashdisk 8gb <--- LINUX

Ok, when launching Linux, no devices /dev/sdX except the pendrive, and no wireless, no audio,... can be found.
There is no micro-SD seen using blkid and fdisk-l.
it is a no way.
startx does not work either since :0 does not found a X server
UEFI blocks all !

http://www.ami.com/support/bios-uefi-firmware-support/

There is no LEGACY. There is Flash of BIOS either.

the bios information is:
bios vendor: american megatrends
core version 5.008
compliancy uefi 2.3 ; PI 1.2
Project version v1.6.3_R008
Build date in 2014
Microcode path 82a
GOP information intel gop driver 7.2.1007

It is a Aptio setup utility 2013
There is main advanced chipset securtiy boot save&exit

tehre is nowhere Legacy !

What to do?

Most distros have uefi support. What are you trying to boot?

A linux pendrive live from Ubuntu.

The boot menu tells:

UEFI : pendrive
and I fear that it is UEFI protect, and Windows 8 boot works well since it is windows.

Ubuntu has good UEFI support. In fact they can boot on secure-boot systems. Here's an article on making a UEFI bootable Ubuntu pendrive.

Sorry my pendrive is gparted... maybe too old?
I have made it with http://www.pendrivelinux.com/univers...easy-as-1-2-3/
Linux boots but no hardwares show into the linux with blkid,...

I tried the debian stable also with pendrivelinux universal creator: http://gensho.acc.umu.se/debian-cd/c...6-standard.iso
but debian does not boot. I ends on windows 8.

I believe you have to use amd64 iso, not i386 iso to boot in UEFI mode.

Thank you! I can see the hard-drive with the iso debian-8.1.0-i386-netinst.iso
Code:
dd if=debian-8.1.0-i386-netinst.iso of=/dev/sdc  ; sync
1) so harddrives are visible!
Linux debian installer can boot after UEFIendrive and then "install debian", keyboard,... !

2) problem, the debian installer usb-pen does not detect the wifi. I will try to find an usb2ethernet adapter.

Some new results.

So I managed to boot Debian Install CD from the USB pendrive.
Ok, so, went to harddisk during debian-installer, and I deleted all partitions of the mmcbl0 and installed Linux normally on it.
I deleted all paritiotn of this windows 8 ntfs and including EFI of 134mb.

I noticed that after installation the debian installer has given me an EFI partition of about 500mb.

So I start the machine after installation success and I end up into a console like stuff with EFI...

what to do?

I believe that I shall have left the previous default EFI partition?
Luckily I did a backup with dd of the whole disk before.
Is it right?

visibly deleting all with including the EFI partition was not a great idea.

http://www.eightforums.com/general-s...partition.html

I shall try to re-make a efi partition to run linux (maybe).

After installing successfully Debian CD-1 iso, then, grub loads normally,... and
in the course of the start of the machine/debian, I get this:

Code:
Begin: Running /scripts/local-block ... done. Begin: Running /scripts/local-block ... done.
Begin: Running /scripts/local-block ... done. Begin: Running /scripts/local-block ... done.
Begin: Running /scripts/local-block ... done. Begin: Running /scripts/local-block ... done.
Begin: Running /scripts/local-block ... done. Begin: Running /scripts/local-block ... done.
Begin: Running /scripts/local-block ... done. Begin: Running /scripts/local-block ... done.
Gave up waiting for root device. Common problems . 
boot args /cat /proc/cmdline)
- check rootdelay=
- check root=
Alter! /dev/disk/by-uuid/lksdklfj does not exist . Dropping to a shell!
...

busybox v1.22.1
(initramfs)
So it seems that debian at start does not find the disks!!
But debian can see them !!! debian-installer could see the disks and install debian on it !!


what to do?


maybe the kernel of debian-installer is better suited than the debian which is on the mmcblk0 itself?

DO not delete the EFI partition, as that's where UEFI looks for the bootloader stubs (grub.efi, grubx64.efi, etc etc). Without that partition, UEFI doesn't know where to look for a bootloader.

Also, it seems the filesystem does matter. Some PCs I used it must be FAT16, others FAT32.

1) I put back the EFI partition using my dd backup image!!

2) I deleted windows 8, and put Debian on it with debian installer cdrom.

3) DEBIAN WORKS On it with into the grub
Code:
 vga=0x318 xforcevesa nomodeset
<============= THIS WAS THE SOLUTION TO BE DONE TO THE GRUB !!

I installed Debian on it. Debian fully works but the hardware (wifi, audio,..) sucks
I boots however the wifi, audio,.. touchscreen are NOT working !!

Debian is JESSIE ! Debian 8!!

I have noticed that the problem with the GRUB is a bug of JESSIE.

acpi = off is not working under JESSIE.


I would like to know if under WHEEZY the ACPI=OFF would work.
