6.10.1 and 6.10.2 boot only for me at first launch after upgrade. Next launches don't boot with no detection of usb with message "cannot mount /dev/sda1 - PRESS ENTER TO REBOOT"
With 6.9.2 i have no problem. So 6.10.1 or 6.10.2 dont fix the problem for me.
What should i do ? Recreate the USB support and delete all partitions, recreate GPT, create FAT32 partition and finally use the tool for recreate the USB support from backup with 6.10.2 in UEFI mode ?
