Solved Cant boot into portable OS

Recently i installed a portable OS onto a micro sd card but when i try to boot into it, it just launches my normal windows version instead of the OS im trying to ( i am trying to boot into it from the Advanced startup )

I never tried to do such a thing, but (on regular base) I do use a linux operating system starting from USB-drive (for image-backupping purposes).

And I know that for that you have to disable the secure boot in the BIOS/UEFI and you have to change the order of booting there as well. Your micro SD card has to be in front of the normal system disk.

Please make photo's of your BIOS/UEFI settings for Secure boot and for Boot order and post them here.

Most pcs will not boot from an SD card, only usb drives. You can put sd card in a usb reader.

For the Surface Pro you find information about (changing) Secure Boot and Boot Order here:

If indeed the PC does not start from an SD-Card, (as @cereberus just wrote) you have to look for that too or put the operating system on a (selfbooting) USB-Drive (Flash memory on USB-stick).

Why reply if you have never booted from sd card, only usb drive?

Most pcs cannot boot from an SD card.

Additionally, your answer is inaccurate regarding secure boot. Some OSs do not require secure boot to be disabled

True - but some will -- even quite old BIOS only PC's. I still use a couple of HP Proliant Gen 8 Microservers as NAS's
which do have boot from internal SD card as an option -- actually that's a useful function as I replaced the DVD drive with an SSD - but it can't boot from the SSD which is where obviously I want the OS to be on. But as I use Linux I only need GRUB (the boot loader) to boot from the SD card it's fine as GRUB then loads the OS to the SSD which is what I want. Note some USB-> SD adapters don't always boot either -- especially with higher capacity micro SD cards --especially if you are using an adapter for reading those -.i.e micro sd Card into SD adaptuer then the SD thing into the USB adapter.
