    Dual boot: Safe to delete 1 OS ?


    Hello !

    Currently, I have dual boot Win7 and Win10. And the only reason I have Win7 is because the drivers for a printer were not updated to Win10. Now recently HP did just that, and I no longer need Win7.

    The way I have it set up is that I have Win7 on one partition, Win10 on another (100GB each) and the rest is Storage. Is it safe to simply remove and format the partition that has Win7 on it ?

    Thanks.

    Go to MSCONFIG (Win key+r, type in msconfig)... will get something similar to this:Dual boot: Safe to delete 1 OS ?-2015-09-12_05h58_09.png
    Delete the OS you no longer want. Go to Disk Management, Dual boot: Safe to delete 1 OS ?-2015-09-12_06h01_42.pngand on the OS drive, right click the partition of the unwanted OS, and delete. Now unallocated , free space.

    EDIT: BACKUP FIRST!! Just good practice.... And after the steps above... reboot...

    As long as it isn't the active partition with the boot files the computer is using to boot with.

    Probably. Khi's recovery drive has EasyBCD and Macrium Reflect which both definitely could be used to restore the boot files.

    Navy is correct Macrium is excellent for finding and repairing the boot records on all partitions at the same time. Kyhi's rescue is here Windows 10 Recovery Tools - Bootable Rescue Disk - Page 43 - Windows 10 Forums and has recently been updated. Also, you can get the free version of Macrium here: Macrium Reflect Free
