My Aspire XC-1760 with :-

BIOS R01-B0 05/06/22 (Now updated to R01-B1)

EC Firmware 1.01 12/03/2021

Processor i5-12400

It came with 1TB hard disk but the plan was to install Windows 11 on a SSD instead. I have been installing Windows since before Windows 95 but this is my first with Secure Boot!

All worked well for many months until I was partitioning a USB connected SSD. Part way through I didn’t notice that the USB drive had become disconnected and think I had just deleted the secure boot partition on C:\!

Booting from a Windows 11 install USB drive does not see the SSD drive listed in the BIOS.

Name Total Size Free Space

Disk 0 Unallocated Space 0 B 0 B

Disk 1 Partition 1: ESD-USB 7.2 GB 2.6 GB

I still have the original Windows 11 hard disk that was supplied with the computer and unused since it was replaced by a clean install on a SSD. Booting from the original Windows 11 Hard Disk progresses slowly and displays the Time and Date on a normal blue display screen! If I press the “Return” key my name is displayed but under it the words “Something happened and your PIN isn’t available. Click to set your PIN again”. Underneath the words “Set up my PIN”. I click “Set up my PIN” and eventually a message about requesting a code to enable to create a new password but no code arrived. The next day I repeated everything possibly giving more time for a network connection and a code arrived and I can login and everything works but rather slow!

If I now boot from the USB disk Diskpart still finds Zero disk space as above!
