dual boot win 10

I had upgraded my old 32 bit win 10 to a 64 bit win 10 system and while I was transferring my files, I dual booted from the original 32 bit Win 10 system. Now that everything is running smoothly, I would like to remove the old 32 bit partition and included
the space in my new 64 bit system. However, when I go into the disk management, it is listing the old 32 bit system as 'system,active,primary' partition and is listing my new 64 bit system as (boot, pagefile, crash dump, primary partiton). I am afraid to make
this partition as active in case I lose all my files. Any suggestion of how to get rid of the 32 bit partition and make the 64 bit system bootable?

Thanks

Wipe a dual boot machine and reinstall Win 10?

I have an old machine that started out on Win 7. I updated/upgraded over the years and it now has two SSDs one with Win 7, the other with Win 10. I created the dual boot a long time ago from the Win 7 drive.

I'm worried wiping will negate my Win 10 lisence since it was an upgrade not the original OS. I have the original Win 7 serial, but I don't think that is relevent to the process any more.
At any rate, I'd like to give the machine to an elderly neighbor, so I need to wipe it and reinstall Win 10. I don't know where to begin. Anyone able to point me in the right direction, for a step by step?

 

Dual boot problem

Hi all.

I have an older PC that used to run XP. I upgraded it to Win 7 and have now upgraded to Win 10. I now want to make it a dual boot Win 10 system, using the second drive as a disaster recovery backup.

When I set up the dual boot Win XP / Win 7, the system put system boot files on the XP disk. Now I can't boot into Win 10 with that disk off line, nor can I format the XP disk to install Win 10 as it has running system files on it.

I have created a recovery USB flash drive but even after setting the boot devices in BIOS to boot from USB, it will not boot from the recovery disk. My next step is to create a recovery CD to see if that will work.

Any suggestions?

Regards,

Steve
