Disk Size ( C ) only left 28 GB from 480 GB after boosting from flash drive and drivers missing

[TPO001]

Hello friends,

The problem is first started from the last update of windows 11

After clicking the windows upgrade and restarting I've received a blue screen with "Boot Device Not Found Please Install an Operating system on your hard disk (3F0)

After that I have done the diagnostic check and both hard disk  drive are passed.

But the window cannot boost still.

After all of this I have decided to boost the windows 10  from the flash drive, and it works but...

after boosting the windows, my disk ( C ) size only left instead of 450 GB and cannot down load the driver software. and disk size is full. furthermore the audio drivers are unplugged as well. 

So is there a way to recover the missing part of the disk ( C ) and how to maintain a fine working window. 

Thank you and best regards

Pai

Any Windows version upgrade like the one you did takes up LOTS of space for the MS files -- which then do NOT get removed after the update.

Here are some things you can do to recover some of the disk space:

Also, the community Win10 Forums has the following suggestions:

Finally, there is a freeware app known as Wise Disk Cleaner. I use it every day to get rid of junk files: https://www.wisecleaner.com/wise-disk-cleaner.html
