Hi,

I am trying to prepare upgrade to Window 11. I just found out that my Boot Manager and Window 10 are saved in 2 different Hard Disks. I tried to change the boot setting in BIOS to the Disk Window saved but it does not work. It saying error of no boot manager.

Here is some information for my PC, my Boot Manager is somehow under F Drive (It is a Plextor 128GB SSD) and the Window is under H: (C:) Drive. (It is under a ScanDisk 240GB SSD). I do have another 3 disk. (E Drive: 4TB HDD, Z Drive: 1TB HDD and D Drive: 1TB NVM) Majority of the program are saved under the H: Drive. I cannot see any other data in F Drive as well.

I want to combine or migrate the Boot Manager and Window together into the D: Drive which is empty. After this is done, I will change the disk format from MBR to GPT for the F Drive. Then, move the whole Window back to F Drive from D: Drive. After everything ok, I will backup and then upgrade to Window 11.

Who can help and tell me how to combine or migrate the Boot Manager and Window into 1 places? Pls kindly share your idea with me.

Pls let me know if you need any other information.

Thank you very much

I would be tackling this issue from a different angle.

whatever drive you want Windows on, get any info you want kept off and onto one of your other drives.
then disconnect all other drives, only leaving your 'soon to be' boot drive connected to the SATA0 port.

use Windows Media Creation Tool to make a bootable USB stick with the latest image of either Win10 or Win11.
reboot the PC with the stick in and BIOS configured to boot from USB first, and install a fresh image of Windows, removing all partitions on the drive when offered.

after the reinstall you can then reconnect all the other drives.

Hi Bruce,

Many thanks for answering my question. I never think from this way. I got couple of question for this:

- When install a fresh image, will the process set the SSD to GPT?​
- Can I use my Window 7 product key to install my Window 10? My Window 10 is free upgrade from Window 7 offered by Microsoft in the past. Or I need to install from Window 7 and upgrade it again?​
- Is it correct I need to reinstall all the program as well?​
​
Thanks

- When install a fresh image, will the process set the SSD to GPT?
honestly, I can't remember, I haven't down it for a while.
I want to say Yes. pretty sure, when Windows installs afresh, it sets up everything it needs automatically.

- Can I use my Window 7 product key to install my Window 10? My Window 10 is free upgrade from Window 7 offered by Microsoft in the past. Or I need to install from Window 7 and upgrade it again?
no need. during the install it'll ask to re-enter your Product Key, click the "I don't have it" and the process will continue.
when you do get back on the web, Windows will auto-reactivate.

- Is it correct I need to reinstall all the program as well?
sadly yes, the drive will be as it was when you first got it - virginal.

I believe a fresh install is always better and reinstall programs - upgrade only if you can't reinstall programs.
You could try this - Backup first
Why not transfer existing windows and programs from current HDD?
This has a 50/50 chance of working.
1. Create Recovery Media (USB or DVD)
  • Click Start , then type "create recovery drive." Windows will provide relevant results as you type.
  • Select Create a recovery drive.
  • At the "User Access Control" prompt, Select Yes to open the Recovery Drive wizard. Keep the check box next to Back up system files to the recovery drive checked, click Next.
  • Connect the USB flash drive to an available USB port, ensure that the drive selected is correct, then click Next.
  • Let the process complete.
Now that you have a recovery media
Disconnect all drives expect windows - windows will not boot.
Put usb or dvd in and boot
Go through the screens to startup repair Click on me
This should create the boot sector onto the windows disk.
Will the computer boot with just windows disk installed?

Or you can try this Click on me
1. Click Start and type command prompt in the search box. Right click the Command Prompt program from the given list and select Run as administrator.
2. At the prompt type bcdboot c:\windows /s c: and press Enter. Make sure you want to boot from C drive. If not, change it to the correct drive letter. Wait for the process to be completed.
