I tried to copy an image file from a gzip’s image (dd) file of a raspberrypi boot drive to an sd card on 2 different pcs (win10 and win11) Based on the log, the write seems to be ok, but the verify fails. The only message I see is “Flash Failed” in the gui.

Hi, based on the logs, the verification is also ok. `gui.js:35 Verifying 1 device, 100% at 78.90 MB/s (total 78.90 MB/s) eta in 0s with 0 failed devices` I think it is a confusing message, which can be caused by an error parsing the results or another issue when trying to unmount the flashed device. Your sdcard should be flashed successfully and able to boot the RPi.
