Numbered Menu does not appear in Advanced Startup

Hello and Good Morning to you all.
I am sorry to post this here, but I couldn't decide which category would fit this the most.
I was trying to disable Driver Signature Enforcement, and after I boot into advanced startup and go to startup settings, and press "Restart", my PC restarts but doesn't boot into advanced startup...I cannot make the F/numbered menu appear.I must be doing something wrong, but I can't seem to figure out what that is.

Hi, from an admin command prompt please run
reagentc /info
and post the result. This will establish whether you have a Recovery partition correctly assigned.

Also post a screenshot of your partitions.

For reference: you may wish to try another method as well, though I'm guessing you'll see the same thing.
Boot to Advanced Startup Options in Windows 10

Hello and thanks for the quick reply.

Well, the obvious thing to note about your Windows partitions is that they are distributed between 2 physical disks, when really they should be on one.




However that probably wouldn't explain the lack of menu options.

What I would suggest is rebuilding your OS with all its partitions (Recovery, EFI, Windows, and one that Disk Management doesn't show) on the one disk.

This is possible without losing your current OS configuration.

That sounds like tedious work.Would you happen to have a guide on how I would do that ?
Would I use a third party partition manager or is it possible through W10 Disk Management ?

Hi, I'd start from the viwepoint of how you got to this situation...

Here's how I'd do it- which should also deal with any issues about Advanced Booting.

a. Make sure you have a full and complete disk image of both disks (you can create an image of each disk or partition or set of partitions separately) using Macrium reflect (to a large enough external USB disk or disks).

(Hopefully you are already using disk imaging routinely if you have followed advice so oft-repeated by tenforums members).

b. Clean install Win 10 to your SSD
c. Check that boots, and advanced startup is ok.
d. Restore the image of 'C:' in place of the new Windows partition
e. Reboot- automated repair should sort things out- if not, you can run Startup Repair by booting your PC from a Win 10 install medium.
f. Deal with any remaining data partition issues.

This is the least technical most routine solution to give you a sound configuration.

You will need: a bootable Win 10 install medium, a bootable Macrium Reflect flash drive (which you can create having installed M Reflect, large enough external storage for disk images.

Unfortunately I don't think I have a USB with such a big memory :/
Isn't there any other way besides doing a clean install ?

dalchina said:

That indicates you aren't using disk imaging... oh dear..

You need two problems fixing.. I wouldn't attempt that without backups as it's such a big reorganisation.

And recall- the clean install is just a means to the end of having your PC back exactly as is by restoring what you have.

Alright, I will schedule this procedure for the next day or so.But before starting anything, wouldn't it be better if I used the native back-up software provided by Microsoft? https://support.microsoft.com/en-us/...ack-up-restore

Thank you for taking time out of your day to help me.
