What a helpful reply! And QUICK too
1) Legacy boot.
It was an official HP article that misled me, possibly an early issue as I didn't filter on date
I felt a little uncomfortable during all the UEFI hassle, as I do this v. rarely, yet I felt sure you should just tap F9 and you get the boot options
You are confirming that's so. Great! That feels right.
2) Fix Boot.
I reckon the SSD windows has not been touched since it was cloned
So I shall try Rescue Boot and straight in Fix Boot; all done in UEFI mode
It either works or it doesn't. I'll soon know.
If fails, I'll re-clone from macrium backup... No sweat
3) It is a SATA SSD, not NvMe, so I think I'm OK. Not that I knew about the NVMe driver issue though
This is actually a friend's PC, and my own is working OK, which helps
I was all cocky this morning, and it all went pear shaped.
Your reply has restored my confidence. I wasn't that far off.
And I've learned something about hidden implications of UEFI v Legacy too
Ten out of Ten to you and the forum I think
- but I won't really know for sure till I try it!!
