Hi Merle Sebzda,
Thanks for reaching out! That issue where the Surface logo flashes for a few seconds and then disappears when booting from a recovery USB is something we've seen pop up in the community. It usually points to either a corrupted recovery image, USB formatting issues, or sometimes a deeper hardware problem like a failed SSD. A few things you can try, use a fresh USB drive 16-32GB, FAT32 format, make sure you're using the correct recovery image for your Surface model from Microsoft’s recovery page, and boot using Volume Down + Power. If that doesn’t work, try Volume Up + Power to access UEFI and check if the USB is detected. You may also send a screenshot of the error here so we can review it. Additionally, please check if the USB and SSD are being detected in the UEFI settings.
Let me know how it goes, happy to help walk you through any of the steps!
Best,
Carl
