Windows 10: [Solved] Fresh Windows install on SSD with GPT wont Boot

Hello Community


This title is found several times in several forums through google. But I didnt found any solution to my problem.


ANSWER: Here is the answer to the problem. If you are sure that you did set up the GPT Partitions needed for Windows right or you let Windows do that and the Disk is not detected by your PC after Installation. Check if the Disk is detected in Legacy Mode. If the PC cant detect the Disk in non Legacy Mode but you are sure that the Disk is GPT, then check the Storage Pool on your Windows. You need to log in to your Microsoft Account on a running OS and the Disks that are in the Storage Pool need to be also plugged in. Then delete the Storage Pool and do the Windows Installation as usual. If you cant do that then I dont know how you can get that Disk working. Just formatting the Disk wont help you and using a tool that writes zeros to the Disk wont help you either!


First my PC Setup and what I want to do:


Motherboard:



Disks: Samsung SSD 840 PRO Series 125 GB Windows installed

Samsung SSD 850 EVO Series 500 GB Games and Programs

Samsung SSD 860 EVO Series 1000GB Games and Programs

Goal: Migrate Windows from 125 GB to 500 GB and throw the 125 GB out. Then replace with another 1000GB SSD for Games and Programs


I wiped the 500 GB clean now even with MiniTool Partition Wizard placing zeros and installed Windows on it with an USB, which was prepared via the Media Creation Tool. I tried it with letting Windows setup my GPT clean Command via Diskpart and then "New" Button when in Windows Setup and with manually creating it 300MB System EFI, 128MB MSR, Windows, 1000MB Windows RE tool. Both methods give me the same error result. While installing Windows I had only the 500GB SSD plugged in with SATA. No other disk was plugged in.





After the installation the PC restarts and I get a black screen with a white underscore blinking. After some time, it switches to UEFI. When I disable Legacy Support in UEFI then I get an Error Message from UEFI that Legacy Support is disabled instead of the black screen with the white cursor. Usually this means that the Disk is in MBR Format but as you read, I prepared it the right way. So somehow my UEFI does not recognize the Windows Manager on the EFI Partition.


I also disabled Secure Boot. Checked that AHCI is enabled. Updated the UEFI on the MoBo. Did a CMOS reset. The Disk while installing is on the first SATA Port and like said the only one used. I tried the same asdescribed with the 1000 GB SSD and had exactly the same result. However, when I started first, I was stupid and formatted the 125 GB as well before the I installed Windows on the 500GB. For a moment I had no Backup Disk with a running OS. But I managed to reinstall Windows on the 125 GB just fine. I dont understand why I cant get those 500GB and 1000GB SSDs to run Windows.


I wasted the whole Weekend for that and I am at the point where I forget about the extra 1000GB SSD I wanted to buy and just buy another 500GB install the OS there and thats it. But I m unsure if a new SSD will solve my problem.


I m really thankful for some solution suggestions. I m conviced there is no error on my side but maybe I overlooked something.


Error Message with SSD 500GB:




UEFI Boot Menu with 500 GB SSD "Windows Boot Manager" missing:





UEFI Boot Menu with 125GB:





When Only 500 GB SSD and USB is plugged in and I go to Command Prompt for ScanOs check I get this:





But with list Partition I can see the Primary Windows partition and I checked there is a Windows installation on it.

windows 10 slow boot

I was having a slow boot issue on my Windows 7 install a little while back. It would take about 30 - 40 extra seconds to boot up for whatever reason.

I would try following these steps, while this didn't solve my issue, it did increase Read/Write to where it should be.

In the end, I had to reinstall my Windows 7 entirely to fix the booting issue. It was taking around 35 seconds to boot, and after the fresh install it takes about 7 seconds to boot.
