Why this helps

When users panic in partition or boot screens, bad clicks happen. A recovery script keeps actions safe and reversible.

  • Protect existing Windows install
  • Reduce accidental partition changes
  • Provide clear fallback path

Emergency sequence

Recovery checklist
  1. 1. Stop and do not apply changes
  2. 2. Boot Windows via one-time boot menu
  3. 3. Confirm files and backups
  4. 4. Retry later with guided dual boot

Detailed steps

Step 1: Freeze the process safely

If partition labels or install options look unclear, stop immediately. Do not continue with manual partition writes.

Step 2: Boot Windows from UEFI menu

Restart and open one-time boot menu (often F12, Esc, or F11). Select Windows Boot Manager.

Step 3: Verify your baseline

In Windows, verify key files open, free disk space is available, and backup destination is reachable.

# Optional from Linux live USB to inspect disks read-only sudo lsblk -f sudo fdisk -l

Step 4: Retry with safer installer path

When ready, choose guided "Install alongside Windows" instead of manual partitioning.

If unsure, stop and generate a diagnostics bundle before attempting again.

How to verify

Troubleshooting

Windows no longer appears in boot menu
  • Open UEFI settings and re-order boot entries so Windows Boot Manager is first.
  • If needed, use Windows recovery USB and run Startup Repair.
Linux GRUB appears but Windows entry fails
  • Boot into live USB and run os-prober / grub update for your distro.
  • If still broken, boot Windows directly from firmware and repair bootloader.
