Dual Win10 boot w/Bootit Uefi, how to...

Postby ILe » Tue Nov 13, 2018 4:33 am

Hello, got BootIt UEFI a couple of weeks ago.
My purpose was to have 2 Win 10, in the same computer. Easy?

Configuration is 1 SSD, where is 7 partitions, ESP, MS reserved, Win10, Win10, "D" drive, Restored, WinRetools.
Dell original configurations, except original "C" has been divided to 3 partitions.
1. Win 10 as a "C" drive, the win I use
2. Win 10 as a BackUp Win
3. "D", which is intend to be a common

After installing BootitUefi, I had one Win to select, which works fine, I suppose? (Tells me something after selecting, but boots up)
2. Win 10 is a copy of 1. Win, which has been copied with Bootit.

So, up to here, it's fine.
Now, when defining an other Win to BootItUefi menu, I should be able to point bootmgfw.efi from ESP partition, but there's only one.

How to add a new entry for 2. Win?

For 1. Win10, there's "Microsoft.001" folder, and I believe I'm missing second folder, from where to boot second Win10?

With BCD edit, I can add second entry to Win boot (BCD/boot), but it's inside bootmgfw.efi, and I can't point it in BootItUefi OS selection.

Are you using the most current version of BIU? Update if not. Did you do the copy in Partition Work? It should have created a copy of the booting files.

Otherwise, I usually create a new folder (Microsoft.002, or whatever's next) and copy the contents of Microsoft.001 into it. Then use the BCD Edit feature in Partition Work to update the references to the Windows partition. For example, using TBOSDT from BIU:

cd \EFI
dir
(should see Microsoft.001 folder here)
md Microsoft.002
cd Microsoft.002
copy ..\Microsoft.001\*.* /s

Then edit the boot item to use the bootmgfw.efi file in the new Microsoft.002 folder (e.g. \EFI\Microsoft.002\boot\bootmgfw.efi) and make sure the "Rename Directory" option is enabled. BCD Edit info can be found in this KB article:

Just bought it a couple of wks ago, ver 1.04.

I copied 2. win10 from original (1.) win10, with copy feature, built in BIU (was it "disk imaging"?).
Somewhere in the forum was told to tick option "copy booting files" (or something like that).
But the only thing I've found, close to that, is "update boot partition", which actually will point 2.(just copied) win10 in microsoft.001... and 1. win 10 will remain unused.
Somehow I believe this option should copy a new entry to boot sector (microsoft.002) which would give an option for boot menu to point bootmgfw.efi from microsoft.001 to 1. win10 and and other bootmgfw.efi from microsoft.002 folder to 2. win10.

As You wrote, "Otherwise, I usually create a new folder (Microsoft.002..." You've created that... but how to do it?
I've copied, with BIU, several times my 1. win10 to an other partition, but a second boot folder (Microsoft.002) hasn't apperared.
And so far I haven't figured out, with which tool/program I could do it manually.

If I somehow manage to create an other folder (Microsoft.002), then using BCD edit should not be a problem...

Then, after BIU was installed... following warning appeared, right after BIU menu disappears, for a couple of seconds.
"Warning: Unable to point UEFI to current boot item (1h 0h)"

Update.
Don't know how to use TBOSDT from BIU, but I created usb boot for TBOSDT.
Boots up, like DOS prompt... but doesn't see EFI. (CD \EFI).

ILe,

If you copy the Win10 partition in Partition Work, copy/paste to Free Space, you get an option to "Add to Boot Menu". This will create a Boot Item. A BCD Edit isn't needed.

OK.
That's what I read from somehere (some forum?).
Would be the easiest way to do it.

When starting to copy, there're "settings" available.
It's a popup window, called "global settings", blue background.

When source/destination has been selected, there's an other "settings" available, which is not a popup, and is called "options", white background.

Neither of those has a selection "Add to Boot Menu".

When/where this option is available?

ILe,

I think you are referring to Disk Imaging. Disk Imaging is not used for the procedure I described. You need to use Partition Work. When you click Paste you will see "Add to Boot Menu".

Paul's instructions refer to using Scrpting on the BIU desktop. TBOSDT boot media can be used but Paul's instructions are easier.

OK, with Partition work it really appeared. The selection.
Last night I copied original Win10 to an other partition, and tick "Add to Boot Menu".
In the morning, less than 60% was done... had to cancel it.
So, now I need appr. 24h time period, to not use my laptop, in order to copy it.
Just don't know when that is possible....

Could try Paul's way, as copying windows takes usually appr. 20 min.
But for some reason, when I created a bootable USB for TBOSDT, it didn't recognice EFI partition?
Got to find a manual for that and play with it.
Partition work seems to not be an option, as it takes too much time.

Disk access can be very slow via UEFI on some systems. In that case, I would do the normal copy (like you did) and manually copy the Microsoft folder and setup the boot item.

In case it wasn't clear, you can run TBOSDT directly from the BIU desktop by clicking the Scripting icon or by selecting the Utilities menu and then Scripting. (The Scripting option won't be available if you didn't include TBOSDT when you created the BIU boot media).

All right, now, more playing ...
Scripting was not enabled, actually it wasn't even a choice.
After downloading a new official package, it appeared.

With it, copying win...001 folder was possible, and settings for the new OS was possible to make.
(Seems, that copying win...001 folder in windows, will cause some weird features? For example, when booting win, it goes to a "restore" mode??)

Anyhow, 2. win boots up, and seems to work.

Now there's (so far) one thing left.
After selecting win from BIU menu, there's a text:

"Warning: Unable to point UEFI to current boot item (1h 0h)"

I wonder whether it's a fault or feature?

ILe,

When you boot each Win10 can you check Disk Management to confirm the correct partition is C: drive.
