How to Remove Windows 7 from dual boot with Windows 10

Johnboy · 04 Aug 2015

I have a little problem. I have Windows 7 and Windows 10 Enterprise Build 10240 set up in a dual boot configuration on the same hard drive. Windows 7 is the first partition on that drive and Windows 10 is the second. I have decided to keep Windows 10 as my main OS and want to remove Windows 7 and reclaim that space for the Windows 10 partition.

What is the easiest way to accomplish this without a complicated and long procedure? I have tried Easeus Partition Master 10.5, but am unable to format or delete this active partition. I tried to format and/or delete this through Windows 10 as well with no success.

Thanks

Note that you might have to repair Windows 10's bootloader using a repair disc/USB drive by typing this command into Command Prompt:

bootrec /fixmbr

I used EasyBCD 2.2 to remove the W7 bcd text and reset the countdown to 0 seconds for the boot menu. Then I formatted the W7 drive. Done.

You might need to remove Windows 7 from the boot tab of System Configuration (msconfig).

Thanks for the answers...Will try both of them this weekend when I have more time to play around with this.

Update: Used GPart and deleted the Windows 7 partition and extended the Windows 10 Partition to include that space. Ran the MBR fix command that was given in a reply here, but my system did not boot. Tried a repair with the system repair disc I created, but still no luck. I ended up just deleting all the partitions and formatting the space as one partition and re-installing Windows 10 again. All is OK now.

Thanks again for the help. That was my first time using G-Part. Looks like a handy tool once I can figure out all the options and use it properly.
