When I say, "FAST", I mean that I downloaded the 24H2 ISO, burned it to a new 16GB Flash Drive, using Rufus, and then installed the OS onto a spare HD/ssd on my MAIN PC. . . in less than an hour. Now, that's FAST!!!
Just for general information, I went into the BIOS here on my Gigabyte motherboard, and I went into the DDR Memory Control and I reset the CAS Latency on the ram down from 11T to just 9T. Then I did a Reboot Timer test. With the CAS Latency at the original 11T setting, the reboot time was 69 Sec's, and after resetting it to 9T, my reboot time was just 56 sec's. A definite performance improvement.
I wish I had done that years ago. Live and learn!!!
Cheers Mates!
