Windows 10: Dual Boot Computer Not Working After Windows May Update

My dual boot (Win 10 and Linux) computer stopped working during the Windows Update to the May update.


Apparently, GRUB stopped working and now Windows won't boot at all. I can still boot into Linux. The hard drive appears to have all of the files, but it must have a bad MBR; just my guess.


I've tried "Bootrec /RebuildBcd" from the command prompt and several similar commands, and all the options in my recovery drive, but it still won't try to boot to Windows.


To make things worse, my old computer developed a hardware problem when I was trying to get it to boot; probably just too many quick power cycles. So I have a new computer that I'm trying to get my old hard drive to work in.


I would really like to not have to reload Windows, cost, and lose my installed programs that are on the drive. Although I should have an older system image that I should be able to load onto the hard drive.


Any and all suggestions will be appreciated.


Thanks,


Bill

Dual Booting with Windows 8.1


The procedure below will allow you to boot Windows separately or in dual boot configuration.
Here's what I recommend to do:

1. Disconnect the drive containing Windows 8.1
2. Install Windows 10 with one drive connected.
3. After step 2, reconnect the drive containing Windows 8.1
4. Boot up Windows 8.1. Open disk management and take a note of the drive letter of Windows 10 OS.
   NOTE: if you boot up Windows 10, then take a note of Windows 8.1 drive letter
5. Open Admin command prompt and type: bcdboot X:\windows where X: is the drive letter of Windows 10 (Windows 8.1 if you boot from Windows 10 in step 4)
6. Reboot the PC. You should have a dual boot screen.

NOTE: To break off the dual boot setting, Win+R->msconfig->boot and delete the none default entry on the list.

 

Performing Dual boot on the computer (Windows 10 and windows xp).

Hi Vaibhav,



You will not face any system performance issues on performing dual boot by loading older Windows version first (Windows XP) and then the latest Windows version (Windows 10) on the computer.



To perform dual boot on the computer, you first have to create partitions to load both the OS onto the drives. Create disk partition by following the steps below and perform dual boot on the computer.

• 
  Press Windows logo + R keys on the keyboard to open
  Run command, type diskmgmt.msc and press
  Enter.
  
• 
  Right click on OS(C hard drive and select
  Shrink Volume.
  
• 
  Allocate the disk space in MB and click on
  Shrink. An Unallocated drive will be created.
  
• 
  Right click on the Unallocated drive and select
  New Simple Volume option. Follow the onscreen instructions and provide a drive name/letter in the process.
  
• 
  Perform dual boot and check if the issue is resolved on the computer.
