Installing Win10 Pro/64 on a new computer build. The installation failed partway through the software load with the Microsoft (non-informational) error message:
"The computer restarted unexpectedly or encountered an unexpected error. Windows installation cannot proceed."
So it's a hardware error, a software error (I've seen a bad install media before,) or a driver issue (highly doubtful, since it's a brand new install.)
Reboot from DVD, delete the partitions, try again.
I started by suspecting RAM. I pulled 4 of the 8 sticks out, reset the BIOS to boot from the DVD, and tried again. Nope.
I started testing the RAM one stick at a time. Same error on the first three sticks. OK, chances of bad RAM are now next to zero.
I pulled the M.2 SSD out, connected power and SATA cables, and added a blank 2.5" SSD. Same error. Not the SSD drive.
For grins I changed the SATA mode to RAID from the default AHCI. The installer completed all the way to the reset. AHA! (I thought...) Nope.
This time I got a BSOD. At least I got a BUGCODE NDIS DRIVERS. There was also a QR code on the screen. Maybe Microsoft will be able to tell me what the problem is! Nope.
The QR code takes me to a Microsoft web page that basically says: "A BSOD means that you have a hardware or software issue." Thanks a lot. Very helpful.
What am I left with? Could be the graphics card. Could be the CPU (highly doubtful.) Could be the motherboard (please God don't let it be the motherboard.)
I decided to google the BUGCODE. One of the sites mentioned that Win10 has issues with some Wi-Fi chipsets/driver combinations. So I disabled the onboard Wi-Fi controller, and hallelujah it worked.
Just to be sure, I put the M.2 drive and all the RAM sticks back in, booted from the DVD, deleted the partitions, and reran the installer. Success!
What a PITA. (No, I can't install LINUX on this computer, so don't even bother...)
