How to Dual Boot Endeavour OS 2021 with Windows 10 (UEFI/Legacy)

bro is that mean I need to install VS code and other programs in linux?

Hey, this is probably a dumb question but does the install alongside option make a swap partition or have some form of swap included ?

Your method somehow didn't work for my legacy bios laptop. after installing linux endeavour OS, the boot menu doesn't show windows 10 option. How do you fix this?

man i have all disabled secure and fast boot and the dual boot option at startup is not appearing. I have to change boot order every time. I try now reinstalling the system step by step as you did but I don't thing I made something different. I ll come back if I find a solution. The thing is that I want online installation so I can put i3 window manager. I had to delete some efi partition that were unessesary but Im starting to believe that there is a conflict with the previous grub of ubuntu i had which i have erased. Lets hope it will work now

TY very much!, In uefi you need to set fast boot off and something else?
