If you can’t access Ubuntu from the boot menu, perform these commands in the Ubuntu Live environment. Just boot from an Ubuntu flash drive and follow the above steps.
Does Ubuntu support Secure Boot?
Secure Boot is a technology that verifies the code that is launched by the firmware to prevent rootkits. Many Linux distributions don’t support Secure Boot, so if you want to install them, you need to disable Secure Boot first.
Ubuntu has been compatible with Secure Boot since version 12.10 and it should work on most PCs with Secure Boot enabled.
However, only the first-stage EFI boot loader is signed by Microsoft, which may lead to some boot issues on certain PCs. If this happens, you’ll have to disable Secure Boot from BIOS.
What are the disadvantages of dual booting?
Regarding the disadvantages, dual booting requires a lot of space on your PC, especially if you’re planning to use both operating systems regularly and install various software on them.
This isn’t a problem with larger hard drives, but if you’re running low on storage space, you might want to free up some space or consider upgrading your storage.
Another disadvantage of dual booting is multitasking. When using the dual boot, there’s no quick and easy way to boot to the other operating system.
Instead, you need to restart your PC and then choose the operating system that you want to access. Keep in mind that you have to do this every time you want to switch to another operating system.
This isn’t a major problem, but it can become tedious at times, especially if you use both operating systems frequently.
Lastly, there are booting issues that can occur, but this mostly happens when installing Windows after Ubuntu or any other version of Linux.
What Ubuntu distros can I dual boot with Windows 11?
Ubuntu has 8 different official distributions and they are the following: Kubuntu, Lubuntu, Ubuntu Budgie, Ubuntu Kylin, Ubuntu MATE, Ubuntu Server, and Ubuntu StudioXubuntu.
As for third-party distributions, there are about 40 of them, if not more. Regarding popularity, these are the top 3 most popular Ubuntu-based distributions:
- Linux Mint
- elementary OS
All Ubuntu distributions can be dual booted with Windows 11 without any major problems, and installing them in dual boot mode is similar for all of them.
The only issue might occur if you have Secure Boot enabled and trying to install older version of Ubuntu, but that can be easily fixed.
If you want to dual boot Windows 11 and Ubuntu, do that by following the instructions from our guide. However, since Windows 11 isn’t still officially released, you’ll need to dual boot Ubuntu with Windows 10 first, and then upgrade to Windows 11.
