It is stuck on the boot menu/ app menu screen and wont fully power on, its a Lenovo thinkpad yoga 14 its been going on

Hello,

I'm sorry to hear your computer won't load past the boot menu.

Perhaps I can be of assistance?

Does your computer ever load to Windows at all?

Gotcha.

B​y experience, it seems as though your HDD (Hard Drive) maybe already failed. The only reason why you can't get past the Boot Menu is cause the computer itself is looking for Windows to boot / load but if your HDD has already failed, then the computer is waiting for you to boot off another drive.

To make sure this is the cause, you can go into your BIOS menu on your computer and try to find the HDD if it is still listed.

Or, you can try to boot into the Lenovo's Hardware Diagnostic software and run it to test the HDD to see if it is still in working condition.

I believe pressing F1 or F2 is the way to get into your BIOS Menu in your Lenovo. Make sure to restart your computer and press F1 or F2 to enter into the BIOS Menu.

Oh, well done.

On the Boot Menu, do you happen to see the your HDD in the list?

ATA HDD1: SanDisk SSD U110 16GB should be where Windows is booting off of. There's only one HDD / SSD that is installed in your computer. What happens if you select it?

So no error message or nothing?

If the HDD / SSD drive is ok and you can't load into Windows then this means Windows is corrupted and must be reinstalled again.

What happens if you select the Windows Boot Manger?

I'm trying to find if your laptop has a recovery partition to reinstall Windows.

Did your computer come with any software disks?

Try this, restart your computer and press F11. Tell me what happens.

Wow. Pressing F11 should've triggered a recovery to reinstall Windows.

Well good thing you told me that cause I was trying to reinstall it as new again but that required erasing everything.

Let's try one more step.

Let's go into your BIOS Menu. When you get to the Boot Menu / App Menu on your screen go to App Menu and choose Setup.

Yes but this requires to open the laptop and pull the HDD / SSD out and buying a enclosure device to connect to your HDD / SSD drive and connecting it to another computer to extract the files off.

Ok.

Head over to Startup tab.

T​ell me what is listed where it reads UEFI / Legacy Boot.

One of these devices. You insert your drive in it and by USB cable connect to another computer and you can extract your files.

It's just like an external HDD.

Where it reads UEFI Only try changing it to Both. Press enter to change it.

Can you navigate to UEFI/Legacy Boot? You should have the UEFI/Legacy Boot highlighted and to your right where it reads UEFI Only, it should be highlighted in black and then by pressing Enter you can choose from three choices.

What else is listed under UEFI/Legacy Boot?

Can you navigate to UEFI/Legacy Boot Priority? Is it listed on your screen?

I assume you also can't change CSM Support to Yes can you?

Darn. That could be the reason why it won't load into Windows. CSM should be set to Yes.

C​ould you go to Boot Order Lock and select disabled?

I have a Lenovo ThinkPad T440 and my BIOS settings is set like this:

​UFEI/Legacy Boot - Both

UFEI/Legacy Boot Priority - Legacy First

CSM Support - Yes

What disk?

I found out something. Try this, go to Security tab, find Secure Boot, enter and tell me what is listed.

Ok, try going to Secure Boot and select Disable. Once done go over back to Startup tab and try to change the CSM Support to Yes.

Choose CSM to Yes then exit and save.

Keep UEFI to Only for now.

It should restart your computer and then we'll see if it loads past the Boot Menu screen.

No. We're trying to tell the computer in how to boot properly again.

Ok, it's a start. Let's go back into BIOS Menu again, go to Startup, select UEFI/Legacy and change it to BOTH now. Save and exit.

If it takes long, try pressing F12 for the quick boot menu. Once there, select your HDD / SSD and press enter.

Besides in UEFI/Legacy having UEFI Only and Both, was there another option to select?

Try changing it to Legacy this time. Save and exit.

Still no luck?

So did you get past the Boot Menu now?

Wow. I just burned out all available options in how to get your computer to boot into Windows. It should've worked when we unlocked CSM to yes and choose Both for UEFI/Legacy.

Only thing I can come up with is perhaps the Windows OS is damaged.

Diagnostics doesn't test the Windows software. It only runs hardware tests.

Does your Lenovo still have warranty?

I was going to recommend to take your laptop to the nearest Lenovo shop and have them check it out in person. Perhaps they can actually get your laptop up and running. Here's a link to find the nearest Lenovo tech shop >>> http://lenovo.force.com/bplocator

Sorry I couldn't get this done through here. In a situation like yours, it's pretty difficult for me to troubleshoot when the laptop is not in front of me.

That is why I recommend to find a Lenovo tech shop service in your area and hope a local tech can fix your issue hands on.
