Solved Can't boot my Pc after checking the box under Maximum memory

[Marianix]

I can boot to bios i don't have yet a bootable usb
But is it related to a motherboard issue?

If you can boot your computer to BIOS setup utility then its not faulty motherboard its the corrupted Windows OS that is causing the boot problem.

Then why is my other hdd not working also?
My third hdd is a win7 pro 32bit and it has no problems

 

[FreeBooter]

Did you installed the Windows OS from the computer that is not booting?
Do you get any error message?

 

[Marianix]

No it is a separated copy of windows so i have two copies of win7
All are in good condition until i checked the maximum memory on msconfig

What you can do is connect the HDD that is connected to computer that is not booting to a working computer and replace registry hives stored in \windows\system32\config folder with registry hives stored in Windows\System32\config\RegBack folder and connect the HDD to not booting computer to find out if Windows OS will boot.

 

[Marianix]

Its 64bit does that matter?

 

[FreeBooter]

The registry hives and backups of the registry hives are stored at the HDD that is connected to the computer that is not booting.

 

[Marianix]

Have you encountered this problem?

 

[FreeBooter]

No i have not but most Windows OS settings are stored at in registry hives you said Windows OS wont boot after you made changes to Windows OS settings.

 

[Marianix]

You mean the msconfig?

 

[FreeBooter]

You mean the msconfig?

Yes any settings configured from Msconfig utility will be stored at in registry hives which is stored in \windows\system32\config folder.

Windows Vista/ 7/8/8.1/10 keep a regular backup of the registry hives handy in case you need to overwrite a corrupted registry hives. By default, the RegIdleBackup task runs every 10 days, so that’s as far back as you would lose if you replaced the current registry hives with the automatically backed-up registry hives files. You can find the backed-up registry files in \Windows\System32\config\RegBack folder. You can connect the HDD to working computer and use Windows Explorer to replace registry hives stored at Windows\System32\config folder with backups of the registry hives stored at Windows\System32\config\RegBack folder that is also stored at not booting HDD.

 

[Marianix]

What should i copy
Replace
Backup

 

[FreeBooter]

In Windows\System32\config\RegBack folder you will found five registry hives files copy them to Windows\System32\config folder.

 

[Marianix]

Thats it?

 

[FreeBooter]

Yes that is it.
