Embarassing problem: now it is more difficult to boot from USB

10. Problem solved !

to earth-shine with his suggestion.

Now I can easily boot with my USB stick again, and install in UEFI/NTFS mode or legacy/FAT32/MBR mode if I wish. It's awesome. Somehow that damn OS, which I inflicted upon myself, caused my BIOS to get corrupted.

If I had a good workbench and a good set of computer tools, I would not have messed up my CMOS battery bracket twice now. The first time, I accidentally broke the holding bracket so that destroyed any chance of restoring it properly. I suppose I could have tried to get a technician to replace it, but not worth the cost and aggravation. I cannot do it myself. Replacing the motherboard ? Again, not worth the cost and aggravation.

This time, the bracket and clip and underlying spring all seem to be intact, but so far I cannot get the clip and spring to hold the CMOS battery in place.

I lived without a CMOS battery last time, and I can do it again this time.

Thank you everyone for your time and suggestions ! You all are the best !
