Windows 10: Disk crash made my C: drive invisible and messed up partition info

I have a 2TB SSD inside a Lenovo Carbon X1 Gen 9, running the December 2022 version of Windows 10. My 2TB is partitioned into the C: drive, about 450GB, and a number of other partitions that hold software, various personal and business files, music, etc. The computer has been acting a little strange, and a couple of weeks ago suffered a BSOD crash. Since then, it has become increasingly difficult to use, and a couple of days ago, the computer just would not boot into the C: drive.

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that

 

Unallocated Space to C Drive

Unallocated Space to C Drive

Hi Travis,

It appears that a disk partition was created but was never assigned its allocation. Assuming there are no files stored in the unallocated partition, perform these steps to combine it with your C: drive:

• In Disk Management, right-click on (C which appears next to the
  Unallocated partition.
  
• Select Extend.

Let us know if you're able to combine the spaces after following the steps above.

Regards.
