[SOLVED] Can't boot to installer

[Dannyps]

I've installed Ubuntu lots of times on my UEFI computer without any troubles. The last few days, I've been trying to install Debian Jessie on my computer. I do the steps bellow:

- Download the corresponding iso (amd64).
- Create a UEFI bootable USB drive with Rufus.
- With Safe boot, Fast boot and CSM disabled, I boot to the USB drive.

I expect to see something like this:


But what I get is this:



I'm using an Asus PC. GL550JK.
The UEFI version is 205 (from Asus Support website).

Things I've tried:
==================
- Booting with CSM on => Same behaviour. It's not my intention to install debian with CSM on, though.
- Using Wheezy instead of Jessi => Same behaviour.

Any thoughts? What else can I try? Do you need more info about anything?

Thanks in advance

- Create a UEFI bootable USB drive with Rufus.

If you only have Windows, use USBWriter instead.
http://sourceforge.net/p/usbwriter/wiki/

If you still have Ubuntu, use:

Code: Select all

# cp debian.iso /dev/sdX
# sync

https://www.debian.org/releases/stable/ ... -isohybrid

Replace "debian.iso" with the full name of the ISO image and replace "X" with the drive letter assigned to your USB stick (plug the stick & run `dmesg|tail` or `lsblk` to find this).

Thanks. Using USBWriter worked. I don't understand why, though... Do you have any possible explanation?

I think Rufus attempts to modify the MBR and the Debian ISO uses a GUID partition table so this messes it up...

Ok, thank you again.
