  1. Deleting partitions in windows 10 (from old linux dual boot)


    I had a linux dual boot on my laptop with Win10. In changing distros I have made a mess and want to start afresh first with just win10 and sorting out partitions. I'd like advice on what linux or redundant win10 partitions I can safely delete on my Lenovo Yoga 2 pro laptop. I'm on Windows version 10.0 19043. Screenshot from Disk Management: And info from bcdedit /enum all and reagentc /info also shown. I hope this helps. My understanding is that partition 10 is the active recovery partition. I'd like to keep a recovery partition rather than a bootable usb/iso. I don't know what purpose the D: serves. Any guidance appreciated, I suspect I can delete partitions 1,3,6,7 and 8 but any clarification welcome and much appreciated. --- Code: C:\WINDOWS\system32>bcdedit /enum all Firmware Boot Manager

  2. 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)

    How to go about building a tri-boot system?

    i dual boot all the time, and going in to tri boot is easy.

    step 1) partition the drive in to 3 partitions ( leaving 1 empty for the linux installer. )
    step 2) install windows on the first 2 partitions.
    step 3) install linux, and let it auto partition the remaining space. ( i recommend at least 30gb of space for linux, because it will make things a lot easier. )

    step 4) enjoy.

    Deleting partitions in windows 10 (from old linux dual boot)

    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.
