legacy to UEFI Issue

[alphabeta]

I installed my windows on legacy but I want to reinstall it as UEFI when I chance the the option in the boot menu the bootable devices are gone and only IPv4(xx-xx-xx-xx-xx-xx) and IPv6(xx-xx-xx-xx-xx-xx) are shown and when one of them is selected I get "EFI Network 0 for IPv4(xx-xx-xx-xx-xx-xx) boot failed " 

 

so how I get this fixed ?

 

P.S. it's Lenovo z50 Laptop

Because the drives are formatted as MBR partition table which can't be detectable in the bootable devices menu.

I'd like to refer to Microsoft for that point:

 

Converting a disk from MBR to GPT through CMD:

1. Open a command prompt and type diskpart. If the disk does not contain any partitions or volumes, skip to step 6.

2. At the DISKPART prompt, type list volume. Make note of the volume number you want to delete.

3. At the DISKPART prompt, type select volume <volumenumber>.

4. At the DISKPART prompt, type delete volume.

5. At the DISKPART prompt, type list disk. Make note of the disk number of the disk that you want to convert to a GPT disk.

6. At the DISKPART prompt, type select disk <disknumber>.

7. At the DISKPART prompt, type convert gpt.

 

if you have a usb drive with a windows installer on it you can run that and press shift + f10 to open up a cmd which can be used to do the above aswell.

Delete all the partitions while installing the Windows.

 

Then click NEW, then click Ok and Ok. In this process, it will automatically initialize the drive to GPT partition table.

 

You can now install the OS and after that, You can partition the drives with help of EASEUS Partition manager if you want.

 

 

Ask me if you want to know how to make UEFI enabled bootable USB.

No need to do such long.

 

It will automatically initiate the drives in GPT when you delete all partitions and create a new partition.

Download and run Rufus software.

 

Insert your USB,

 

Select your USB from "Device" in the software menu,

 

Select GPT Partition scheme for UEFI computer,

 

Select the Windows ISO image in the little CD icon,

 

And then start the process. Your USB drive will be formatted and copied with Windows Installation files in it.

 

Then try to boot.

 

It should work.

 

Don't missout to select GPT Partition scheme for UEFI computer. It is important.
