how to make os option menu appear in a dual boot pc?

Hi,
Mam,

1. I could boot into both win7 or 10 through multiboot menu F8.
It places multiple boot options for you but it's called one time boot menu. Multiboot menu is actually what we established on win 10 disk.

2. Now, We would take cover that system crucial parts are not accessible from each other :
(a) As you said Its from within windows 7 :

(Option 1)

(b) from within windows 10 :

(Option 1)

3. I think you know that the partition 'First' on win 10 disk is already not accessible from win7.

4. Hello ..
For this i re-did it. I changed priority for win 7 to be first.
When i turn on my pc , it goes directly to win 7 without the dual menu.
So i suppose it works as you expected.

Be clear about it there is difference in changing boot priority and disabling a drive from booting options.

5. You can also have a metro style ( win 8 & win 10 ) boot loader for the win 7 disk with the help of EasyBCD.

Hello mr.Vineet
Have a nice evening.


I removed the yellow assigned partitions from each os as guided.


And i have just now realised that i cant access "first" on win7.. why is that?
Is it because its a primary partition?

I dont want to bother you with further questions, you have already helped me quite alot.

Hi Mam,
Good Morning,

1.And i have just now realised that i cant access "first" on win7.. why is that? Is it because its a primary partition?
Because it is not assigned a drive letter in win 7. I thought you did so sometime because normally it doesn't happen on its own. No, Then boot in win 7 & assign a drive letter to the 'First' partition. Drive Letter - Add, Change, or Remove in Windows - Windows 7 Help Forums
(The same link as above but now we are doing it all opposite!)

2.I dont want to bother you with further questions
No botheration for me, i am enjoying. But to maintain the forum's dignity, we should not go off topic. You can always make new posts in the proper section for a particular problem OR you can just discuss anything in the 'General Discussion' section.

Thanks & Regards. ...
