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

Xeratul · 08-06-2015, 11:12 AM

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 UEFI

endrive 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?

Xeratul · 08-07-2015, 01:37 PM

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

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.

Gave up waiting for root device. Common problems . 
boot args /cat /proc/cmdline)
- check rootdelay=

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?

goumba · 08-07-2015, 08:08 PM

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.

Xeratul · 08-08-2015, 07:02 AM

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!!

Xeratul · 08-08-2015, 11:30 AM

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.
