  1. Can't boot into Win10 after deleting linux partition


    Ok so, I screwed up somethings and I am a by no means a pc expert so I need someone with more knowledge about this stuff.

    It happened when I deleted 2 partitions from my SSD where kali linux was located, which I dual booted with Windows 10. I deleted the partitions from a live linux distro when windows was probbably in hibernation because it was going to do some updates.

    After that I tried everything to fix it but I did not succeed and I am stuck now. :/ I couldn't reinstall kali or Manjaro because it would error out (something with python.boot and efi). Also I tried bootrec /fixboot with a live Windows repair USB but that also didn't work (acces denied errors). Gparted clearly shows my Windows partition still is there with some other 500mb partition but that doesn't show as bootable.

    When I try to install grub or mount disks in Manjaro live terminal I get all sorts of errors and can't proceed (I did install grub2). But grub and grub2 did't show any filesys with the ls command so. I got myself a boot repair live USB and ran the recommended repair thing. Wich showed that there was indeed 1 opperating system found (Windows 10 ofc). But after the repair I STILL can't boot into it, this time grub does show NTFS when using ls.

    The Boot Repair Utility recommended to ask for help on forums and upload the "Boot Info Summary" so here I go: http://paste.ubuntu.com/p/49Yt2Nc47B/

    I hope this posts reaches some smart guy who maybe could look into it and sees what I am missing out on. Thanks

    I am sorry for my bad English, I am not a English man.

    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.

  3. Windows 10 Installer deletes linux partition

    I have a Ubuntu and windows dual-boot and while upgrading to widows 10 during one of the restarts grub wouldn't boot a partition and went into recovery so I used a Ubuntu live CD and GParted informed
    me that my linux partition was missing. It was listed as un-allocated. This means that the Windows 10 installer deleted that partition. (The helpdesk told me to post it here)

  4. Can't boot into Win10 after deleting linux partition

    /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 Can't boot into Win10 after deleting linux partition :)
