Clean Disk 0 Convert GPT Install | Generated by AI
Question: Disk 0 confirmed as the UMIS NVMe 512GB drive, correct target — proceed with clean?
Answer: Yes, this is the right disk. Confirmed: NVMe, Online, 476GB NTFS Volume C, Healthy, not read-only. This is your target SSD, not the small Disk 1.
Proceed:
clean
Wait for DiskPart succeeded in cleaning the disk.
convert gpt
Wait for DiskPart successfully converted the selected disk to GPT format.
exit
Close the command prompt window entirely, then from the Repair menu restart into the Windows 11 USB installer (not Repair again — you need the full Setup GUI to get to partition selection). Go through language/edition screens to “Select location to install Windows 11,” click Refresh, select the unallocated Disk 0, click Next.
Critical check this time: after clicking Next, wait a few seconds for Setup to auto-create partitions, then if it errors again immediately go back to the partition list screen and look — you should see 4 entries on Disk 0 (System/EFI, MSR, Primary, Recovery). If EFI System Partition is present this time, the install should proceed past the reboot without the earlier failure.
