Clean Convert GPT and Reinstall Windows | Generated by AI

Home 2026.07

Question: Now in command prompt (via Repair your PC) — what next?

Answer: Run diskpart and redo the clean/convert, same as before:

diskpart
list disk

Confirm which disk is your main SSD (the ~476GB one).

select disk 0
detail disk

Check it says Partition Style: MBR or GPT, and confirms it’s the right disk (not the small 14GB Disk 1).

clean
convert gpt
exit

Close the command prompt window, go back to the main Repair/Setup menu, and boot into the Windows 11 installer USB again (not Repair — you need the actual Setup flow to select install location). From there:

  1. Get to “Select location to install Windows 11”
  2. Click Refresh
  3. Select the now-unallocated Disk 0
  4. Click Next — let it auto-create partitions

Then immediately check the partition list before hitting Next again — confirm EFI System Partition shows up alongside MSR/Primary/Recovery. That’s the thing that was missing last time and caused the boot failure.
