Travelmate was working just fine, I loaded Photoshop elements 9 from a USB DVD reader which completed successfully and asked for restart to complete. It now just hangs on ACER logo screen. All attempts by the laptop to fix this loading problem fail and the BIOS has most of the useful stuff unavailable (e.g. only boot from windows, no USB option) . I understand I can set a supervisor password and disable secure boot that might enable me to restore from a full AOMEI backup? Since mouse on BIOS options, USB port (I can write the BIOS to USB OK) all work and I find it hard to believe that Photoshop trashed the entire Win11 system so I am hoping for a quicker fix? All help much appreciated.
