Do you want to create new System Reserve partition?

If Windows 10 installed HDD missing a EFI System Reserved partition you can create one by following below instructions.

Please boot your computer with Windows Installation Media and from Windows Recovery Environment start the Command Prompt.

From Command Prompt execute below commands one at a time:

Code:

Diskpart

List Disk 

Select Disk 0

List Partition

Select Partition X

Shrink desired=100

Create Partition EFI

FORMAT FS=FAT32 LABEL="ESP"

Assign Letter=W

Exit

 bcdboot C:\Windows /s W: /f  ALL

Use "List Disk" command to find out disk number assign to Windows 10 installed drive.

Replace number 0 zero with disk number assign to Windows 10 installed drive

Use "List Partition" command to find out Windows 10 installed partition assigned number.

Replace X letter with Windows 10 installed partition assigned number.

You may need to replace C: drive letter with Windows 10 installed partition drive letter.

I have to warn you Diskpart tool is very dangers so please make sure to execute Diskpart command carefully.

You can't assign same drive letter to any partition.

What are you talking about ???. Don't you know that both his disks are MBR disk type ? and you are telling him to create EFI partition which only used for GPT disk.

It lists the partition but fails with the boot files.

It shows there is no free disk space on disk 0 , 2 &3 and only 1024K on disk 1 & 4. Maybe just another bug.

In your last thread I've asked if you wanted to install as Legacy-MBR or UEFI-GPT. You answered a UEFI-GPT and installed as Legacy-MBR. After Updates, System can't boot. Repair is required. Is it possible?

Is your BIOS up to date?

What is funny is you asked me question like i don't know what is MBR disk is if this is not the case then it is obvious that i did not know he is using MBR disk.

I guess I missed some settings creating the bootable USB with RUFUS.
My motherboard is a bit old. If I remember correctly I've updated once, couple of years ago.

Please consider another clean install followed by drive testing.

I think that's what I have to do.
Could you suggest ways for drive testing? Software, cmd, whatever...

For Drive heath you can use Samsung Magician or CrystalDiskInfo

For a complete drive test you can use SeaTools

Last BIOS for your P8Z77-V LE is Version 1104
Only update using BIOS update option (don't do it under Windows)

Megahertz listed some.

Run HD Tune (free version) (all drives)
HD Tune website
Post images into the thread for results on these tabs:
a) Health
b) Benchmark
c) Full error scan

Run Sea Tools for Windows
long generic test
Post an image of the test result into the thread
SeaTools for Windows |
Seagate
How to use SeaTools for Windows | Seagate Support US

Check the BIOS for Legacy and UEFI options.

Legacy > MBR partitioning
UEFI > GPT partitioning

@Megahertz
@zbook

A lot of useful material provided.
Thanks a lot!
I'll proceed and get back with results.

A clean install is the optimal time for MBR to GPT as there are no risks of data loss.
GPT allows > 100 partitions

OP can you please execute below command to let us know if disk we are working is GPT disk or not if we are working with GPT disk there will be asterisk symbol under GPT entry as shown at the screenshot i have posted.
