If Windows can’t find drive C:, this is usually a drive problem, not an app issue.
What to check first:
Disk Management (Win + X)
– If C: is missing, RAW, or unallocated, Windows can’t read it.
– If it exists but has no letter, assign C:.
BIOS (F2/F12 on Dell)
– If the drive doesn’t appear there, the HDD/SSD is likely failing.
If C: does appear, run:
chkdsk C: /f
sfc /scannow
Bottom line:
If the drive isn’t seen in BIOS, it’s a hardware failure and the drive needs replacement.
