  1. Deleted one boot partition


    Hi,


    I am hoping someone can help with a simple solution?


    I used to have 2 bootable Windows 10 partitions on the same hard disk, as I needed two totally separate logins/operating systems. When booting, I was asked which one I wanted to boot from and all was good.


    Unfortunately, one of the partitioned operating systems had a problem and I had to reset the PC using the blue screen Troubleshooting options in Windows. It asked me for my login password for the partitioned system I needed to reinstall windows on and off it went. All looked fine until I restarted and I now do not get the option to boot into the other non repaired partitioned operating system.


    I cannot see any option in the blue screen menus to access it anymore. I think the new windows installation has over written the boot manager so it now only thinks there is one OS.


    I can see the other drive partition when in Explorer, so it has not been deleted.


    Please can someone help, and advise hopefully a simple solution to recover the option to boot from the other OS.


    Many many thanks in advance.

    :)

  2. /boot Partition?

    [Solved] /boot Partition?

    Ok, I like playing around with multiple operating systems so I tend to have a few installed at a time. My issue is related to the bootloader. Every new Linux OS I install installs its own version of Grub. That's fine until you delete that partition.... *Bang Head :banghead:

    I was thinking about creating a small (ie ~50MB) partition that /boot will reside on. This way I can have one copy of Grub that would boot my several OS(s) depending on what they are. I think this is a good idea so I can delete one OS's partition and still be able to boot the other OS(s).

    Unfortunately, I am not an expert with bootloaders and I'm not really sure how /boot has to do with booting. Can someone tell me how feasible my idea is? I'm looking for a way to have multiple OS(s) but only one bootloader so when I delete one OS, the bootloader will still be intact.

    Any ideas/suggestions/advice is appreciated! *Smile Deleted one boot partition :)

  3. /boot Partition?

    If you have a newer CPU, I would suggest using some Virtualization software.

    Virtual machine software that's free like Virtual Box or a "to buy" one like Vmware...

    You can install, mess with and even straight up destroy OS's in a nice, safe little sandbox, and it doesn't hamper a thing *Wink Deleted one boot partition ;)

    Deleted one boot partition

    Delete my W10 Partition

    Do you want to safely delete your Windows 10 partition and use only Windows 7?

    If Yes, then boot to your Windows 7, run msconfig, go to "Boot" tab, you will see something like this :

    Choose "Windows 7" and click "Set as default", then choose "Windows 10" and click "Delete", restart if asked or necessary.
    Now the boot information for Windows 10 has been deleted and you can safely delete your Windows 10 partition (make sure no important files are on the Win10 partition). To delete and extend your partition you can use many partition manager tools.
