# Installing Debian 8.6 on Lenovo Thinkpad t460s



## Overall Status



This repo generates a debian NetInst `.iso` file for t460s.



1. For installation: Access to internet via eth0 interface is needed.

2. It creates a user `debian` with password `insecure`

3. User `root`has no password. Access to root via `sudo su -`

4. It creates an encrypted LVM partitioning with

	* /boot type ext4 size 250 MiB

	* / type ext4`size 10 GiB

	* /home type btrfs size rest of space



Feel free to change thinks (see [t460s.postinst](https://github.com/micressor/lenovo-t460s/blob/master/profiles/t460s.postinst) and [t460s.preseed](https://github.com/micressor/lenovo-t460s/blob/master/profiles/t460s.preseed)) before

you create the `.iso`.



**WARNING:** this is an almost fully automated installation. Once you boot

from the USB media: **!!! ALL EXISTING DATA ON THE DRIVE WILL BE LOST !!!**



*Last successful test was tag [0.1](https://github.com/micressor/lenovo-t460s/tree/0.1) with debian 8.6 (jessie).*



Have you successful tested a later version of this repo?

Open a issue and let me know. Thanks. :-)

## 1. On Windows: Update UEFI BIOS



1. The easiest way to update UEFI BIOS, do it on windows. Download and flash

the latest from [here.](https://filedownload.lenovo.com/supportdata/product.html?id=Laptops-and-netbooks/ThinkPad-T-Series-laptops/ThinkPad-T460s)



## 2. Build debian netinst CD form this repo



	apt-get update

	apt-get install -y simple-cdd git xorriso

	mkdir ~/src

	git clone https://github.com/micressor/lenovo-t460s.git

	cd lenovo-t460s

	sudo build-simple-cdd --conf profiles/t460s.conf --dist jessie --force-root



## 3. Install .iso to usb media



Copy generated `.iso` file to your usb media device `/dev/sdX`:



	dd if=images/debian-8.6-amd64-CD-1.iso of=/dev/sdX bs=1M

	sync



## 4. Prepare UEFI BIOS



Configure your BIOS like this:



* Restart -> Load Setup Defaults



* Config -> USB -> USB UEFI BIOS Support [Enabled]



* Security -> Secure Boot -> Secure Boot [Enabled]



* Security -> Secure Boot -> Reset to Setup Mode -> [Enter]



This changes Platform Mode to `Setup Mode` and Secure Boot Mode to

`Custom Mode`.



To get HDMI Port working:



* Config -> Display -> Boot Display [Display on dock]



### Optional



* Config -> Keyboard/Mouse -> F1-F12 as Primary Function [Enabled]



## 5. Install from media



**WARNING:** this is an almost fully automated installation. Once you boot

from the USB media: **!!! ALL EXISTING DATA ON THE DRIVE WILL BE LOST !!!**



Insert your usb media and boot your t460s with F12 option to select your

media. **Note**: Not all usb media's (I use a SanDisk) are recognised.
