Windows 10: System config: Unable to change to higher number of CPU cores when booting up if choosing...

I have 8 CPU cores, I tried to boot with only 1 and the OS was super slow. I opened System Config to change it back to 8 and I only saw 1. I did solve this by unselecting the number of cores option. If this is a bug, please fix it, thanks.

Win 10 BSOD after reducing number of CPUs

• Win 10 x64 running in VMware Fusion VM on MacBook Pro w/ 6 physical cores & HT.
• When VM is configured with 5+ CPUs, Windows runs fine.
• When VM is configured with 4 or fewer, BSOD INVALID SYSTEM CONFIG INFO
  • WINLOAD.EFI missing or corrupted
  • Attempt to repair using ISO image fails

OS X 10.15.4, VMware Fusion Pro 11.5.3

Win 10 Enterprise

Version 1703

Build 15063.2108

Any suggestions appreciated, as I need to move this VM to another HW config with fewer physical CPUs.

Thanks!

 

Is it safe to change CPU core setting in msconfig on HP laptop?

Do not fiddle with 'Number of Cores' in msconfig, Windows knows which cores to engage in which order at boot time!

Set your power plan to 'High Performance', right click on the CPU graph and choose "Change graph to ► Logical processors" then all cores will be utilized 100% during use.
Never mind boot time.

 

Stuck on BSOD Bad system config info after changing number of cores

So I changed the number of cores in msconfig and now my computer will not boot. I can't even get it to boot in safe mode. I also tried to reset numproc and truncatememory but they don't even show up in bcdedit on command prompt! I can't even reset my computer.
PLEASE HELP
