Windows 10 is split between 2 drives

[Georgi Gospodinov]

Hello,

 

 

I was trying to use MBR2GPT for the Windows 11 upgrade but it returns a validation error because apparently my Windows 10 installation is somehow split between 2 drives.

 

You can see in the screenshot that the SSD says "Boot" and the other drive says "System".

 

Whenever I mark one of them not active, Windows is not booting and returns "No operating system found"

 

Is there a way to fix this and upgrade to WIndows 11 without formating my SSD and losing all of my apps?

 

Also, why is there no "System Reserved" partition?

 

 

 

Thanks!

Use Easybcd to move your bootloader to the system drive. Always unplug all drives except the install drive when installing Windows, it's a Windows thing.

Thank you for sharing this tool, will it be possible to do the opposite? Move System to the boot drive?

The "system" label doesn't matter.

 

It does seem you have everything needed to boot on the SSD, can you boot with the HDD disconnected? If yo then you might be able to convert with it disconnected.

Your Windows install was done in Legacy mode so there's no EFI partition.
