I will try to look at your posts daily and reply, I leave for work early and get home late.
1. Next time the PC has issues booting I will look for error code.
2. I have the following USB devices attached
a. Weston Digital external drive: USB3
b. Logitech Nano Receiver: USB3
c. USB3 cable for connecting/charging phone. Nothing connected when booting.
d. Logik Hub: USB2. I have removed for the time being.
3. 3 No. results for CHKDSK for the new SSD attached.
There are known USB boot problems on X99 , so I am not sure if your issues are one thing or you have several none related issues. attached is a ASUS Q-Codes PDF I made from online posts elsewhere.
There are SD Errors in the new CHKDSK Reports too......
Did you check if Trim is working ?
In Magician is installed turn off Rapid mode if used? and uninstall it
Try Bios 2101 again , use USBFLASHBACK rather than EzFlash
As a bit of a novice on what happens behind the scenes in the operating system. Can you explain what are SD errors are where they are on the CHKDSK log. Do you have a link to a site that explains CHKDSK that I can read up on.
I saw a report yesterday of someone with boot issues etc on one the ASUS Forum's I'm on ,after He tried 3301 on his X99a , he said he had no issues on 2101 too , so I am wondering if the new Bios's for Broadwell E are no longer 100% good for Haswell E chips like we have too.
Not OCing are you? did I ask that ? if so put everything back to Auto , Optimised Defaults when you go back to 2101 and see how it goes 1st.
I keep looking at your system specs to check but it is actually
System: Self build
OS: Windows 10 Pro
Mother Board: Asus X99-A/USB 3.1
CPU: Intel Core i7-5820K 3.3GHz 6-Core Processor
Memory: Corsair Vengeance LPX 32GB DDR4-2666
Graphics Card: Gigabyte GeForce GTX 970 4GB
PSU: EVGA SuperNOVA NEX 750W
Hard Drive: Samsung SSD 850 PRO 256GB
Your system is very close to my X99 system , I'd have the 3.1 too if it hadn't died and killed the CPU too.
SD=Security Descriptor it is cleaning them up each time which is why it says it found no issues at the bottom
from one of your chkdsk files...........
Stage 3: Examining security descriptors ...
Cleaning up 777 unused index entries from index $SII of file 0x9.
Cleaning up 777 unused index entries from index $SDH of file 0x9.
Cleaning up 777 unused security descriptors.
Security descriptor verification completed.
38034 data files processed. CHKDSK is verifying Usn Journal...

CHKDSK doesn't actually fix the SD Errors apparently , just claims them back , but not sure why they are there...

On my board everything after Bios 2101 is for the new CPUs. I am still running 2101 and have never tried the newer bios versions. Are you using the original X99 board or a second generation X99? I am just curious. The 2nd generation boards were built to accommodate the changes made in the new CPUs. Sure they said they would work on the 58-59 series chips, but.....
I have an original 2011-3 board and a 5930K and have had none of the problems mentioned in this thread. Maybe I am just lucky. (knock on wood). It just strikes me that if you are seeing the loading screen, the BIOS has finished POST and it is all on the OS and HDD. Not that I think I know everything, just trying to understand what is happening.
He is on 1st gen , see post #19 or #35 above for his Desktop specs not his listed laptop specs , same board I had , but I am now on 2nd gen a X99A II (801 bios) after a RMA but still on 5820K .
All help and ideas welcome , still no sure if it is one issue or several cos of X99
especially since I've had nothing but trouble on X99 since a new build in Feb.
