A hard drive is invisible to disc management

Simply does not even appear anywhere in any program in win 10.
However drive appears in the bios.
Using Ubuntu drive appears in gparted and disks, and I can create and delete partitions on it.

The history of the drive, it recently had a severe boot problem, and I copied most of all my data off. If I tried to boot win7 or ubuntu from it, it error-ed, for windows saying ' a disk read error has occurred'. However in the ubuntu file manager all the files are there and can be copied.

Is there a program that can show the drive in windows 10? I think, when win10 boots, it somehow rejects the drive as a drive.

1) First check to see if the drive is identified by the BIOS.

2) If the drive is identified by the bios then open each:

a) device manager > disk drives > post an image into the thread

b) disk management > widen these two rows before posting an image: Status and Volume > double check the status column and make sure that is sufficiently wide so that none of the characters are cutoff > post an image into the thread

c) file explorer > post an image into the thread

3) Download and install: Drive letter view version 1.6

Ok here they are. The missing 750gb Hitachi drive is in the memmory of device manager as a hidden device. As of course a while ago it used to work in windows.

here is the other end of Drive Letter View

Yes the drive appears in the bios.

Run an admin command windows. Run diskpart, then automount enable then restart. Do you see the drive then?

See Enable or Disable Automount of New Disks and Drives in Windows

Can you see the drive and explore the contents using Minitool Partition Wizard?

Bios screen to show the 750gb hitachi drive. And windows wanted to do a major os update. so I have been battling with this since yesterday. I thought it had died, it boots 10 to that revolving wheel, then the whole screen goes black after a long time, then it reboots. A reboot loads linux grub which defaults to ubuntu. Then I have to restart and it gets hung on the bios screen. The only way forward is to unplug the PC from the wall and reboot. I select win10 to boot, it goes through the same mess.

So I booted the win10 CD, and did a SFC /scannow. it comes back clean and says it is in middle of upgrade. So I shut down, and it finally starts upgrading now at 50%, but then it shuts down to restart and I am back to the black screen again for a very long time! Then again the update screen and it is at 75% now.
Win 10 update is taking a very very long time. Booting that install DVD also took way too long, about 45 minutes to get to the command prompt to run sfc.

its up to 84% now.

I did get the login screen, logged in and doing more updates.
