Hi, I bought a T440s and am trying to install Win 8 in UEFI mode. I have an original Win 8 DVD (system builder) and tried it via USB as well. My problem: There's no UEFI DVD/USB option in the boot menu (F12) - only DVD/USB without UEFI. However if I put the DVD/USB in my friends MacBook Pro the EFI option is shown. So the problem is probably the T440s.
I tried a lot of different settings in the BIOS:

UEFI only/both
CSM enabled/disabled
Secure Boot on/off
Quick Boot on/off

Furthermorem, the T440s is equipped with a 500 GB Samsung EVO SSD. MBR/GPT should not be the problem, since it should still show the UEFI option in the boot menu even if the SSD would be partitioned in MBR.
What am I doing wrong?

Hello Mistapsn, and welcome to Eight Forums. :)

If you use the settings below, do you see the same partitions that are in screenshot under step 8 at that point? If so, then it's installing as UEFI.

UEFI only
CSM disabled
Secure Boot off (you can turn on after installation has finished)
Quick Boot off (you can turn on after installation has finished)

Hello,
Recently assembled a brand new PC using the asrock Q1900DC-ITX Motherboard. I have a brand new Samsung 850 SSD 120GB, 4GB ram, etc.

I have a Windows Enterprise 64 bit ISO file. The Motherboard is UEFI. I followed the step by step directions in this tutorial. I used Rufus on a 16GB flash drive. All went well.

I made the adjustments in the BIOS to boot to the UEFI USB drive, restarted, then windows begins to install. Problem is, I only get through the 2nd step where Windows is beginning to install (with the green check marks etc). I then get various errors including 0x80070057 and this one most often 0xC0000005 - verify installation sources are accessible.....

Ive been trying various things over the last 3 days with NO luck. Any suggestions? Also, will a bootable windows DVD work in my situation (with UEFI BIOS)?

Im getting desperate lately:)

Thanks,
Brandon

Cannot get this to work on my laptop.

It seems I can only boot off the usb stick enabling legacy mode.

When I make the partitions in the setup it keeps making MBR on my SSD not GPT.

If I follow the guide the USB isnt bootable at all.

--edit--

Was due to the filesystem i had selected ntfs.

However fat32 has a 4 gig filesize limit so I ended up having to split my wim file to make it work with fat32.

The windows installer is an odd beast, here is some anomalies I have had with 2 usb sticks.

Originally both my usb sticks were MBR yet one would not allow partitioning MBR drives, the other would not allow GPT, I could never find the difference between the two to find out why. I was able to install GPT win8.1 on my desktop tho using GPT with the fast usb stick (which was blocking MBR installation).

My new laptop is GPT, however the fast USB stick was creating MBR partitions. This is why I had to make a GPT USB stick, because the installer will only create GPT partitions on my laptop when the USB stick booted from GPT.
