Hi Zara,
Thanks for reaching out. hHere’s how to reset your Surface Pro 7 without a CD:
First, try the built-in reset:
If your Surface still turns on, go to Settings > System > Recovery > Reset this PC and pick Remove everything. You can then get a fresh copy of Windows from Microsoft's servers (Cloud download) or reinstall it from your Surface (Local reinstall). If things are acting up, Cloud download is the better choice.
If that doesn't work, use a USB:
You'll need another computer and a USB drive (16–32 GB).
- Get the Surface Pro 7 recovery image over at Microsoft’s Surface Recovery page. You'll need to log in and enter your device's serial number.
- Format the USB drive to FAT32, and make it a recovery drive using Windows’ own tool.
- Extract the files from the downloaded recovery image to the USB drive.
- Plug the USB into your Surface, hold Volume Down, tap the Power button, and let go of Power while still holding Volume Down until the Surface logo shows up.
- Then, go to Troubleshoot > Recover from a drive, and choose whether to just remove your stuff or fully clean the drive.
What if you don’t have another PC?
You can still reinstall Windows through Advanced Startup:
- At the sign-in screen, hold the Shift key and click Restart.
- Then, head to Troubleshoot > Reset this PC.
Keep in mind that this only works if the recovery stuff on your Surface is still good.
Heads Up!
- Make a backup of your files, because resetting erases everything.
- Keep your Surface plugged in while it's resetting.
- If BitLocker asks for a recovery key, grab it from your Microsoft account.
