Title: [SOLVED] Unable to boot from ssd on thinkpad t460
Post by: jyp on 2016/12/10, 19:52:27
Hi everybody
Just bought a Thinkpad T460 and was very keen to install siduction on it.
I removed the original hdd with Windows and replaced it with a Samsung ssd; also upgraded the memory to 16G.

The machine boots fine from the usb drive with siduction on it.
The installation  was always successful (I tried many times either with efi or legacy only).  In the "BIOS" settings, I tried to get rid of anything related to Windows (secure boot ... etc).

The machine does not boot from the local ssd; I always get a silly screen asking to choose the boot device and choosing the Samsung ssd only brings back the same window over and over. I search the forum and found some advice but always the same result. I am at lost. Any idea?
Thank you.

Did you try installing, say Ubuntu, for testing?

Hi devil
No, I have not tried Ubuntu because using siduction kind of spoils you ;-)

Asking to boot from hard drive does not work.

Choosing _hardware detection_ from the live usb and checking Disks, I get the following:
Code: [Select]
>Disk 2
   Disk 0x81 (EDD30)
   ...
   MBR: Grub 2
   > Partition 1
      ...
      type: indication that this is legacy MBR
      boot flag: No
     ...

Using gparted, I flag the first partition with boot.

Thanks for the quick reply

Set the bootflag!

Using gparted, I put the boot_legacy flag on /dev/sda1
Did a new install.
Same result :-(

Tried using fdisk (x for expert mode, A for the boot flag) but no success. The ssd still does not boot.
The new version of fdisk does not offer the usual simple command (_a_ to toggle boot).
Maybe there is a better way that I am not aware of. I will keep trying but...

Thanks towo

The simplest way is using cfdisk.

Problem solved :-)
@devil: no need to test with ubuntu, siduction is more than good enough thank you!
@towo: setting the boot flag was the trick of course. Following your advice in another post, I went the legacy way.
Using fdisk I created a fresh partition table <o>; then the option <a> to put a boot flag became available and this solved the problem.
Thank you all.

thanks

It was a fresh install on a thinkpad t460.
After, I did <apt-get dist-updgrade> (not yet used to apt) that went perfect (even with more than 1500 pkgs) except for the manpages (upgrade warnings today).
