How to fix 25H2 problem on Surface Pro 7

To recover the Surface Pro 7 and fix the 25H2 issue, first focus on getting a working USB recovery drive that the device can boot from, then use it to reset Windows.

1. Recreate the USB recovery drive correctly
   • Use a USB drive that is at least 16 GB.
   • On a working Windows PC, download the correct Surface recovery image for Surface Pro 7 from the Surface recovery site (as described in the referenced Q&A) and follow the instructions in Creating and using a USB recovery drive for Surface.
   • If the USB was prepared manually and the Surface does not recognize it, ensure it is formatted as FAT32 and made bootable:
     1. Insert the USB drive.
     2. Open Command Prompt as administrator.
     3. Run diskpart.
     4. Run list disk and identify the USB disk number.
     5. Run select disk X (replace X with the USB disk number).
     6. Run clean (this erases the USB).
     7. Run create part pri.
     8. Run select part 1.
     9. Run format fs=fat32 quick.
     10. Run active.
     11. Run exit.
     12. Copy the Surface recovery image contents to the root of the USB drive.
2. Make sure Surface can boot from USB
   • Enter Surface UEFI and verify:
     • Enable Boot from USB devices is On under Advanced options of the UEFI Boot configuration screen.
     • If a boot order is configured, Enable alternate boot sequence is On.
   • If a Windows Insider build was previously installed, toggle Secure Boot: turn it Off, save and exit, then turn it On again so the USB boot drive is recognized.
   • If the USB still does not boot, try another USB drive.
3. Boot from the recovery drive and reset Windows
   • Boot the Surface from the working USB recovery drive (see Boot Surface from a USB device for details).
   • When the recovery environment starts:
     1. Choose the language.
     2. Choose the keyboard layout.
     3. On Choose an option, select Troubleshoot.
     4. Select Reset your PC.
     5. On Reset your PC:
        • Select Next.
        • Select Yes, repartition the drives.
        • Choose Just remove my files (faster) or Fully clean the drive (more thorough).
        • Select Reset.
   • This will reinstall Windows on the Surface Pro 7 and should restore network and NAS access if the issue was caused by the 25H2 update.
4. After reset
   • Let Windows Update run until no more updates are available.
   • Test Internet and NAS access before reinstalling additional software.

If the USB drive used for recovery was larger than 32 GB and is now stuck with a 32 GB RECOVERY partition, delete that partition and recreate a full-size volume using Disks & volumes or Disk Management as described in the references.
