Hi. I bought an Asus laptop with Windows 8, my brother update to Windows 8.1. But was a deception. We decide to install Linux Mint 17.2 Xfce.

I made the same like always, i formated all disk, and i installed Linux Mint.

At boot, the laptop go to Bios, and no more. Didn't have options at boot section.

I'm desesperate.

What can i do?

Thanks

Might be an UEFI laptop. Did you disabled secure boot in bios?

Might help to have a look here

Thansk for answor.
No, i didn't do that. I formated all disk. I don't have windows system.
With USB live distro, i see the partitions with system files.
But i just cheked, BIOS dont recognize these partitions, just CD/DVD and USB memory when is load. No more.

Hi.

Did GRUB install?

Yes, i made all instalation normal. But, at reboot system with new linux, just go te Bios. And at Bios not detect the linux partitions, just CD/DVD and USB if is connect.

Of course linux partitions are Ext4. I think don't recognize it. And i don't know what to do.

use your install disk/usb and from a live session open a terminal and post

and

post results back here. Secure Boot mentioned earlier is a setting in your bios screen.

Mint, being based on Ubuntu, should be able to leave Secure boot ON (Ubuntu is signed).

HOWEVER, it would require an EFI partition to boot if you still have secure boot on (since that means legacy is off). Did you create a ~200-500 MB EFI partition as the very first partition, or are all linux partitions? If you didn't create the EFI partition and secure boot is on, that's the problem. Grub probably attempted to install to the MBR of the hard drive but the hard drive is GPT, and thus no longer looks at the MBR for anything.

Thanks tocky. i wil do sudo "parted -l" and "fdisk -l" just now.

Timothy - IJust did a frseh installation, with a new /boot partition. Was not possible use fat2, i use ext 2. But is the same, the laptop go to bios inmediatly.

At connect USB and choose drive to boot, it show 2 Linux Mint, one start with UEFI at name. I used that. But nothing.

Exactly, how i made a EFI partition? What is that? Im reading, but i don't find that options in "parted" section at install.

This is that i get at use command: sudo parted -l :

mint@mint ~ $ sudo parted -l

Warning: /dev/sdb contains GPT signatures, indicating that it has a GPT table.
However, it does not have a valid fake msdos partition table, as it should.
Perhaps it was corrupted -- possibly by a program that doesn't understand GPT
partition tables. Or perhaps you deleted the GPT table, and are now using an
msdos partition table. Is this a GPT partition table?
Yes/No?

And, this is using sudo fdisk -l:

mint@mint ~ $ sudo fdisk -l

Yes Jamison, i use grub. Was installet an harddrive. But, as i understand, BIOS don't "see" that partitions. Even using a /boot partition (ext2). Was not possible use fat32

Based on what you posted, yes, you are using UEFI w/ GPT hard drive partitioning, which means you MUST have a VFAT partition as the first partition, mounted to /boot/efi and set as bootable as your EFI partiition for grub to install to.

If you do not want to do it this way, you will need to go into BIOS and turn off secure boot and enable legacy mode to boot to the MBR, but this will also require a reformat of the hard drive to MBR from GPT.

Thanks Timothy. You are telling me that I must create a partition using the option "Efi boot partition". Then, I must use that for something, put there something, or is for system, just i created and its all? I do my other partitions normally?

Yes, create the FIRST partition on the disk of ~200 MB using that EFI boot partition. If you have the option to create it as EFI boot partition it will automatically use it correctly. If you DON'T have the option for "EFI boot partition" then it's just a vfat partition that is bootable and mounted to /boot/efi, this will accomplish the same thing as creating it as an EFI boot partition but doing it entirely manually. This is where grub will actually be installed by the system now. As long as you create it then your install should work as grub will be able to install.

All other partitions create whatever & however you want (with EFI , it's honestly easier to not use a seperate /boot partition IMO, but you still CAN, just not really as advantageous anymore). But that EFI partition must be created for grub to be able to install correctly.

Just wondering, shouldn't Ubuntu (Mint) install handle this automatically?

Not if you choose manual partitioning. Which many prefer because most installers just don't set it up the way we like (for instance I always found *buntu installer wants to use far too small a / partition if you tell it to use a separate /home partition).
