Windows 10: Setting number of processor in advanced boot settings causes windows to fail booting

Hi everyone, so I have a lenovo z50-75 laptop with latest windows 10 pro installed and when I try to set the "Number of CPUs" to max cores of my CPU, my system fails starting gets stuck on the windows logo and the loading circle never shows up any idea why is this happening?

Here are my specs:

Windows: Win 10 Pro Edition 64bit 10.0, Build 19042

CPU: AMD FX-7500 Radeon R7, 10 Compute Cores 4C + 6G 4 CPUs ~ 2.1Ghz

Manufacturer: Lenovo

Model: Lenovo z50-75

RAM: 8gb

DirectX: 12


Thanks!

Windows 10 fails to start after setting number of processors in advanced boot options

Hi Al,

I did something stupid and can no longer get into my computer....

I have a hp elitebook 8760W with 16GB of RAM. When doing renderings, I noticed that it never uses more than 4GB of memory, even when all 4 cores (8 logical processors) are maxed out at 100%.

Googling the topic, I came up with a suggestion of going into advanced boot options and checking the memory checkbox, forcing the use of 16GB rather than unchecked (auto).

While there, (and here comes the stupid part) I also checked the number of processors checkbox. Not knowing if it refers to physical processors, number of cores or logical processors, I went "safe" and selected 1.

The computer rebooted fine, but on running task manager again, it revealed that I was still running less than 4GB RAM and now only one processor, instead of 8. So back I went and unchecked the checkbox for the number of processors. All subsequent attempts
to boot into windows failed and all I get is a blue screen with:

your pc ran into a problem and needs to restart. We're just collecting some error info, and then you can restart. (100$ complete)

if you'd like to know more, you can search online later for this error: BAD_SYSTEM_CONFIG_INFO

I also tried restoring to a previous restore point, by that failed as well.

Any help or advice would be much appreciated.

New Secondary Drive Causes Boot Failure Windows 10

For the second time now, Windows 10 failed to boot after initializing and formatting a spare drive (using Windows Disk Management). After the boot fail, UEFI boot settings were still set to boot from Windows Boot Manager, but it still wouldn't boot, just goes into diagnostic mode, fails to repair boot problem, and goes to the repair menu. In advanced options I can then load a recent image (made with Windows 7 Backup and Recovery in control panel), and everything goes back to normal. My question is what causes this problem, and how do I repair it without re-imaging Windows? I don't recall ever having this problem in other Windows versions, only in Windows 10. Anyone else notice this problem?
