I’m sure there are lots of posts out there, that point to info on this… PLEASE: Point me in the right direction!
My PC cr#pped itself, so led me to purchasing a new (to me), PC.
Old PC: Optiplex 9020 Mini Tower… Not Win11 compliant.
New PC: Optiplex 9060 SFF. Win11 Compliant
So, decided to try putting old HDDx2 (GPT partitions) into new Computer - they are OK.
HDD#1: Boot drive with Win10/Tumbleweed/Ubuntu
HDD#2: Various ‘inactive’ partitions.
When I try to boot the old drives, Win10 boots fine, but Linux gives:
“Operating system loader failed signature verification. Warning: The file may have been tampered with!”
Help!
Can I fix this? How? Or do I have to reinstall? Tried running install USB, but get the same message…
Thanks,
John.
