Windows 10 cant be installed on GPT - Cant boot dvd in UEFI mode

Hello Guys,

recently i purchased a new laptop that came with win10.

The laptop is Lenovo z50-70

Unfortunately my brother managed to download so many viruses, that I decided to do clean Win 10 install. I had no important data on the laptop and I thought it would be the easiest solution.

So I inserted Win 10 dvd that I got with the laptop into the drive and went on with the process. Decided to not keep any data, formatted the drive, and when I needed to choose where I want windows installed, it told me it cannot be installed on GPT Style partition, which I found weird, because Windows was installed there before.

The partitions look currently like this:

So I did some reading and found out that I should boot in UEFI mode so that I can use the GPT style partition, however when I wanted to boot from DVD using the UEFI, it wouldnt work.

Using these boot settings:

I got this result

Then I played around with the boot options a bit:

Resulted into this:

Just a black screen with LENOVO. I tried multiple times and either nothing was happening, the PC was silent or other time the dvd drive was making rhytmical noises over and over again.
Opening the DVD tray got me this:

Got me here:

And using these settings:

Got me into the windows installation, but again could not install because of GPT.

To be honest I have no idea what am I doing, but since the windows was installed there before and apparently on the GPT partition, it should be somehow possible.
Perhaps the issue lies within the DVD?
If possible I would like to avoid deleting the partitions that were there before.

Here is some more information that could help:

This is what I get after pressing boot options after pressing the oneKeyRecovery button:

Thank you for any help you can offer.

Hello, trying to use the restore to factory settings does not work. Something about missing partition I think, however I did not remove any partitions ,just formatted the one that contained the OS.

The dvd that came with it is Win 10 install DVD. When I boot it in legacy mode, it behaves exactly as expected.

I can use either win 64bit default settings or other OS default settings.
I suppose I should use the win 64 bit ones?

When you get to the screen that lists all the partitions existing on the hard drive, press Shift + F10 (you might have to also press the FN key to get the actual F10 - Shift+FN+F10). This will open a command prompt Window. Run the following commands that will erase the entire hard drive:

Diskpart
Select Disk 0
Clean
Exit
Exit

When you get back to the screen with the list of partitions, click the Refresh function. You should see Disk 0 listed as nothing but unallocated space. Highlight the unallocated space and click Next to let Windows 10 create the partitions it wants and proceed with the install.

Okay, I used the defaults:



Bu I got the EFI DVD/CDROM boot failed message.

I suppose this will remove the factory partitions and wont use the UEFI features?

In that case I ll need to finds USB stick.

Any reason why it would display the efi boot failed?
