Hello

Could you please help me.

1. I was on Windows 7 with 3 TB Toshiba, everything was fine....

2. But when i performed clean install of Windows 10, it does not see last partition! It sees it as unallocated space!

Here's the screenshot of the driver managament

Could you please tell me what to install to make it work again. Actually i need its data.
The only solution i see is to perform recovery from backup which and then copy all files and then install all again.
 
I cannot read Russian so I don't know if you have these partition names or not:

This is what win 10 creates on a fresh install on an UEFI motherboard

Partition 1 - Recovery
Partition 2 - System - The EFI System partition that contains the NTLDR, HAL, Boot.txt, and other files that are needed to boot the system, such as drivers.
Partition 3 - MSR - The Microsoft Reserved (MSR) partition that reserves space on each disk drive for subsequent use by operating system software.
Partition 4 - Primary - Where Windows is to be installed to.

What is meant to be in the last partition? If you expected win 7 to survive through a fresh install, that isn't how it works. If HDD is formatted as GPT win 7 will not boot anyway.

Are you trying to keep win 7 or fresh install win 10 over it? Depending on your bios type, what you do to get win 10 on varies at that stage. See here: http://www.tenforums.com/tutorials/1950-windows-10-clean-install.html
 
Hello Warp,

My system is in other hard drive and boots from it.

My question was about second hard drive which is 3 TB for data. There was a tool called AsusTek Disk Unlocker, which is not available for Windows 8/10 now and its setup does not work...

I found old version of that tool which installs and now i finally managed to get all my data....

Thanks!
 


Actually after reading your post i got the idea to see what tool was used for 3TB extension, so i opened backup and saw it.

Thanks anyway!
