Windows 10: After Win10 re-install, HD has gone from 1TB to 13GB

I have a Dell 3277 AIO with Windows 10.After Windows update I began having black screen. I went through all the steps listed on the Microsoft site and ended up reinstalling Windows 10 using a USB flash drive and the file from Microsoft.Now my disk shows only 12.8 GB space, making it almost unusable. I don't even have enough space to download Support Assist.Any help appreciated.

Portable HD 1TB not reconized since Win10 Fall update

1TB SP Armor portable HD not recognized on 3.0 or 2.0 USB ports since Win10 Fall update. Ports will read USB flash drives. Also 1TB drive will read on another PC running Win 10 on both 3.0 & 2.0 ports. I have deleted drivers and reinstalled. Any suggestions
will be helpful. Thanks, Tom

 

clone MBR HD to bootable GPT partition?

My HP Vista laptop took a swim and died. I pulled the 320MB HD, put it in an external enclosure and found it still good. Bought a new Dell Win 10 machine w/ 1TB HD. Plan was to:

• 
  Partition off a piece of the new 1TB w/ native Win10 Disk Management.
  
• 
  Clone the 320MB Vista drive into the new partition w/ Easeus Partition Manager.
  
• 
  Run Paragon-adaptive-restore on the Vista partition.
  
• 
  Set up as dual-boot Win10 / Vista.
  

Ran into problems right away. Apparently can't clone the MBR HD to a GPT partition and have it remain bootable. Don't see a way to do this without wiping the new Dell 1TB clean – which I'm hesitant to do, especially since I'm about 6000 miles from
home right now.

• 
  What's the solution to cloning the MBR drive to a bootable GPT partition?
  
• 
  Am I on the right track? I really want to preserve this Vista installation - I have 30+ years of data in legacy programs on it that would be very difficult to access in Win10.
  

TIA

 

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.
