Hello Microsoft Community,I recently attempted to install Linux on my HP Pavilion laptop, which was previously running Windows 11. During the installation process, Linux seems to have overwritten my Windows installation, and now my PC cannot boot from the internal drive.Issue Details:I initially had Windows 11 installed on my laptop.I started the installation of Linux, but during the process, the system overwrote Windows instead of dual-booting.Now, when I try to boot the PC, it does not detect any operating system from the internal SSD.I acces

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.

Yeah, but he's throwing OS X in there. Not quite as easy to do, but not all that hard. Manual configuration of GRUB is necessary.

 

How can I move windows 10 boot files to another drive to allow linux

One advice to you before installing LINUX. Don't let GRUB loader to take over the MBR and control the booting process, but install GRUB on its own partition. Normally, when installing LINUX, it will install GRUB on the MBR of the disk and be the default boot manager. take a look at the screen shot:




By default, #1 will be installed and once done, you'll get an ugly dual boot screen from GRUB. #2 is the prefered way.

1. Keep Windows boot manager in control.
2. Since GRUB boot loader is in its own partition, you can boot it as a stand alone. You can
   also make an image or clone to another HD partition on another PC and it will work.
   What I did is to install and setup LINUX in one PC, make a copy and restore to another PC
   so all will be up to date.
3. Windows won't know LINUX existed until you setup dual boot and you'll get the nice looking
   windows GUI dual boot menu using Easy BCD. If you later want to remove the dual boot, remove the
   entry with Easy BCD.
4. Any update from Windows won't affect LINUX and vice versa.

Having said all that. It's extremly easy to set up Linux to work with Windows. Here's the steps:

1. Install Windows which you've already did
2. Boot up LINUX to install. Follow the steps untill you get to the screen asking where to put the GRUB loader.
   Assuning that you'll install on the same disk as Windows, say Disk 0 then LINUX will select /dev/sda to install the loader,
   This step is important and if you miss it, it won't work. Select /dev/sda# where the # is the partition you will install LINUX,
   set up swap space and the rest to continue.
3. Once done, reboot to Windows. At this point Windows is not aware of any LINUX existed since the GRUB
   loader is in its own partition.
4. Download and install Easy BCD then run -> Add new entry -> select GRUB2->Select the installed Linux partition.
   
   
   
5. Reboot, you'll will get the nice looking dual boot menu.
