Set up a dual operating system and install Windows 11.
Set up a dual operating system and install Windows 11.
Updating from version 10 to 11 replaces your bootloader, which is why you can't access your Linux partition. Windows 11 includes certain security features in your system that require specific configurations. Since you managed the update successfully, it's likely the setup is correct. You might need to rebuild the bootloader using GRUB again for it to function properly.
The update succeeded initially but then the system failed to start. Windows automatically rolled back to an older version. I have multiple installations with different boot methods—GRUB for Ubuntu and Windows, both on the same partition. In BIOS the default was set to Windows, but those settings didn’t get updated. Now in Win10 it works fine, though the Linux option isn’t accessible from there.
I think the issue could stem from Win11 requiring secure boot enabled, which may conflict with your Linux boot settings. There are resources available online that explain how to configure this for compatibility with both Windows 11 and a Linux installation.
Phew! I was planning to set up Ubuntu in dual boot mode, but if it needs any adjustments to function properly, I'm holding off. Fingers crossed for a quick solution soon. Appreciate the help in this thread!
You'd need to start with Windows before getting into the Linux part, right? I'm setting up a native Linux install just to enjoy playing Steam games on both platforms for fun.
I've been using Linux since 2011, and I discovered a key tip: "DON'T DUAL BOOT." It's really frustrating. Every Windows Update can mess with your GRUB bootloader. With Windows 11, security features like Secure Boot and TPM make dual-booting even more complicated. Still, if you must, the best approach is to use two separate disks—one for Windows, one for Linux. Press F12 during boot (or whatever your system uses) and select the correct disk. Avoid messing with GRUB, and Windows won't ruin your boot partition with each update! To be clear, GRUB works great... it's Windows that has issues! They intentionally break the GRUB loader during updates to push Linux out.
HI there ,first of all use bootable pen drive and then update the os to win 11 , move to bios/uefi select linux grub as your default boot loader done ! if updating to win 11 affects the boot option then reinstall the kali with 10 gb swap area and 90 gb main partition
