Dell latitude E6220 crashes after install 64bit, but installs ok with 32bit

[lamap]

Hi
After I install ubuntu 16.04 (and also 16.10) 64bit, the pc does not boot. Caps lock blinks.

Instalation with Mint 64 is OK.

instalation with ubunt 32 bit is OK.

They all boot without problems with usb stick.

Can you please help?

Thank you.

Luis

That looks like it should be an UEFI system.
But 32 bit installs would only be BIOS/MBR. With 64 bit you can install in BIOS/MBR or UEFI/gpt partitioning.

Do you have Windows? Or just installing Ubuntu?

It was my understanding that systems from about 2012 needed sputnik, but then all those additional drivers were included in 14.04.
So I would think any newer version would still work.
