Please forgive--I only have cell access:

Win 10 build 1607 w/last week's update
Toshiba Satellite laptop A665
BIOS: Phoenix SecureCore Tiano Setup ver. 2.30

Trying to solve problem, in MSCONFIG> boot tab > advanced settings > I unchecked # of processors to use at boot.

Now can't boot Windows. No bios setting for # of processors. On boot up, get error

bad system config info

System then goes to "blue screen" options. Tried everything in Advanced options -- System Restore 3x using 3 different restore points - error code 0x800700b7

Startup Repair no-go

Startup Settings - will not boot into any Safe Mode

Do not have System Image, any system/OS disc or any recovery disc or USB drive and no backup available (literally in another state).

I don't think System Reset (reinstall w/saving programs and data) will work or should be necessary, partly because already can't boot to Safe Mode w/networking.

I CAN ACCESS Command Prompt and can see all of HDD and files.

bootcfg gives ERROR: Cannot open boot.ini file. (I cannot locate--not used in Win10?)

Don't understand how to use bcdboot, don't want to make things worse.

One Web comment said to change msconfig settings in Registry Editor but no "msconfig" key.

Another said use bcdedit but not entirely clear instructions :

>bcdedit /deletevalue [identifier] truncatememory

but I'm not confident in trying that. [identifier] would be either GUID, default or current. Oddly, there was a GUID but now it shows "default" and I didn't make any changes !!

truncatememory value is 0x10000000.

Please help--can't afford repairs or replacement or continued downtime, am trying to find job and resume and info only on HDD.

Thanks!

FIRST: NEVER DO WHAT I DID! Do not mess with the processors on boot setting EVER.

MS 2nd level tech said bcdedit would not work.

SOLUTION :

Did Reset, saved data but could not save programs. All works great.

Downside: just need to download software, install and adjust all system and program settings.

Upside: got rid of all clutter in one move--PC now fast again!

Hope this helps somebody.
